What is the fuel consumption during thermal neutralization? 2

Answer

Influencing factors on the amount of fuel for waste incineration

The process of thermal neutralization and disposal of waste is carried out with constant or temporal use of fuel. Waste incineration is also possible without the use of fuel under conditions of constant continuous supply of waste to the main chamber. In this paper we’re going to find out what factors effect on fuel consumption and the functional mode of burners.

The first factor is what type of fuel will be used. There are several types of fuel used for waste incineration: diesel, gas, waste oils, fuel oil, etc. The calorific value of one type of fuel will be different from another. For instance, natural gas is more calorific compared to diesel, which means that gas consumption will be less than diesel consumption.

The second factor affecting the amount of fuel consumption is the calorific value of the waste. The higher the calorific value of the waste, the less fuel will be required for combustion (high-calorific waste is capable of sustaining self-combustion). To minimize or reduce to zero the consumption of fuel required for evaporation of water in the waste, heating to set temperatures and the cost of heat loss, possibly by the heat released by the waste. For example, the calorific value of contaminated plastic is more than 6000 kcal/kg, the calorific value of food waste is about 800 kcal/kg. So, unlike food waste, plastic can be burned without using fuel.

           The third factor is the amount of air supplied to the main and secondary chambers. If the air is supplied without preheating, i.e., taken directly from the environment, that requires a significant amount of heat to heat it up to the preset temperatures. Consequently, the more air oxygen is required to burn the waste, the greater the fuel consumption for heating it. The more organic compounds in the composition of the waste, the more amount of air for waste incineration will be required. For example, the burning of 1 kg of contaminated plastic requires stoichiometrically about 9 kg of air, the burning of 1 kg of food waste requires about 2 kg of air. However, plastic is more calorific and the heat released during its combustion is sufficient to compensate the temperature loss.

         The fourth factor is the size of equipment for thermal treatment and disposal of waste. The larger the unit, the more fuel will be needed to heat up the main and secondary chambers. For instance, there will be 4 kg/h of fuel consumption because of heat losses on the pressure vessel walls of the HURIKAN 150 incinerator, and 15 kg/h for the HURIKAN 1000 incinerator. At the same time, when the incinerator enters the operating mode, i.e., full heating and maintaining of a constant continuous supply of waste to the main chamber, the effect of size of equipment on the amount of fuel consumption is reduced due to different productivity: the more waste is burned per unit of time, the more heat is released, therefore, a more productive plant generates more heat.

         Thus, the amount of fuel consumption for waste incineration is variable, and depends on a number of factors. The fuel consumption can also be minimized or reduced to zero.
What is the difference between Hurikan and Volkan installations? 3

Answer

Eco-Spectrum produces three models of incinerators, which are divided into chambered incinerators of Volkan series, chambered incinerators of Hurikan series and rotary incinerators of Hurikan series. The fundamental difference between chamber incinerators and Hurikan is the productivity and volume of incinerated waste. Volkan series differ in loading volume, while the performance does not change (from 45 to 75 kg per hour), and the index in the name of the incinerators (150, 200, 750 ...) indicates the volume of a single load. Hurikan series are characterized by high performance, achieved due to the presence of grates and the volume of the afterburning chamber of gases. The grate system developed by our company allows to increase the area of combustion of waste, thereby achieving high productivity. Combustion system is designed in our company. The index of incinerators of Hurikan series indicates the performance of the incinerator (70, 150, 300 ...).

Rotary Hurikan series are a rotating lined drum that allows the disposal of liquid waste, such as oil sludge, waste oils, etc., in addition to solid waste. Due to rotation, the waste is mixed, thanks to which a certain productivity is achieved on certain types of waste, which a chamber furnace cannot provide.

Catalog
Is the use of incinerators environmentally safe? 4

Answer

The technology of waste and waste gases neutralization after waste neutralization has been approved by a positive conclusion of the state expertise of the federal agency of Rosprirodnadzor. Eco-Spectrum regularly analyzes the ash obtained after waste disposal, as well as testing of equipment for emissions at customers' operating sites is carried out on an ongoing basis.

Incinerator installations designed by our company meet all international standards of environmental and sanitary safety. Environmentally friendly emissions are provided by correctly calculated gas afterburning chambers and gas filtration systems. Thermal neutralization of exhaust gases in the afterburning chamber of gases occurs at temperatures exceeding 1100 degrees, which meets all international standards and ensures effective burning of dioxins and furans.

How cheap is it to burn waste? 5

Answer
The prime costs of thermal waste treatment are fuel for combustion. A multi-layer lining developed by our specialists, and automated control system significantly lower the fuel consumption in comparison with analog equipment. The automated control system of the incinerator allows to cut fuel costs by burning waste.

The burner is only needed for firing the waste, after that the fuel supply is automatically turned off by the program and logistics controller (PLC) and the air is supplied to the combustion chamber to support waste burning, while ceramic insulation layer and concrete lining perfectly keep the temperature inside, preventing heat loss, and effectively save fuel.

In case of continuous supply of waste in small portions to the main chamber, the generated heat can be sufficient to compensate for the costs of heat loss (evaporation of water, heating of waste and air), it makes possible to minimize or to set burners’ fuel consumption to zero. And this is the reason why costs under condition of proper operation of the equipment are minimized. And if we take into account the possibility of obtaining a secondary, economic and energy resources, the waste incineration process can become cost-effective.
How can the thermal energy obtained from waste incineration be used? 6

Answer
A huge amount of thermal energy is released at the process of waste burning, and it can be reused due to additional equipment manufactured by our company - a heat recovery system. The received heat energy can be used for premises and water heating.

What are advantages of incineration compared to other methods of waste neutralization? 8

Answer
The worldwide challenge of waste management is the rational recycling and the maximum waste reduction. The solution to this problem must be comprehensive.
For example, amount of municipal solid waste generation in Russia is about 63 million tons / year, even if to use the most modern and efficient waste sorting complexes, there will always be waste that cannot be reused (tailings).

In case the benchmark indicators of the National Project “Ecology” are reached, the amount of tailings for disposal will be more than 30 mln. tons per year. This number does not solve the issue of waste accumulation and landfill overusing, but only slightly extends their operational life. At the same time, the environmental pollution issues, as a result of the negative impact of landfills, remain unresolved and the energy resource or MSW are unconverted to energy.

Currently, the incineration is the most effective way to reduce the waste disposal level of tailings to zero amount of waste, it allows to neutralize waste the safest way for environment, while reducing its amount and get secondary material and energy resources, turn waste into raw materials and generate heat and electricity.
Our company has developed and successfully implemented these projects by production of secondary material resources, such as waste into heat for industrial premises and using ash as an industrial material.
What are the advantages of incineration relative to other disposal methods? 9

Answer
The main problem around the world in working with waste is rational recycling and maximum reduction of waste volume. It is necessary to approach the solution of this problem comprehensively. 30% of the volume of waste generated worldwide can be recycled, this can be achieved using modern waste sorting methods, but no matter how modern and efficient the waste sorting complex is, there will always be waste that cannot be recycled (tailings) and at the moment the most effective way is incineration, which allows you to get rid of waste as cleanly as possible, while reducing its volume by 20 times.
What can be burned? 10

Answer
By incineration, it is possible to neutralize waste with organic inclusions that can be decomposed when exposed to temperatures. The list of waste is presented in the State Environmental Report on the equipment and is based on the legislative framework.
Brick or concrete – which lining to choose? 11
Answer

Disadvantages of bricks:
- frequent repairs;
- it falls out during operation, and untimely repairs lead to the burnout of the metal frame of the equipment;
- despite the high refractory properties, the brick material has a high thermal conductivity, which entails large heat losses (it is impossible to apply an insulating layer in the brick lining, which leads to fuel overspending to constantly maintain high temperatures in the chamber);
- on the surface of the incinerator, the temperature can reach 80-100 degrees or more, which is unsafe for the installation operator and reduces the service life of the equipment due to the constant thermal load on the frame.
Advantages of concrete:
- equipment operation without repair for at least 5 years;
- due to the technology of using an insulating layer and a metal frame, a huge amount of heat is saved, fuel costs for maintaining are minimized, which makes the cost of waste disposal low.;
- at high temperatures in the furnace (and it reaches more than 1000 degrees), the outer surface of the incinerator does not exceed 50-60 degrees, which ensures the safety of the operator during operation;
- thanks to the principle technology of monolithic filling of the lining, maximum mechanical stability is ensured during transportation, movement, relocation and, in fact, operation.
What types of fuel can the equipment run on? 12

Answer
In the production of our incinerators, we use a high-quality burner device of Italian production EcoFlam, which can use fuel as: diesel, natural gas, associated gas, waste oil (not suitable for regeneration), fuel oil. Also, the burners can be dual-fuel (from the above). If necessary, we can consider analogs of burner devices. The more powerful the pumps are needed (for example, for waste oil, fuel oil), the more expensive the burner device is, but it can pay off faster if the fuel source is available.
What are the main nuances of safe operation of the equipment? 13

Answer
During the operation of the incinerator installation, it is necessary to follow the equipment operation manual immaculately, and also observe safety precautions. Undoubtedly, the most important point is a competently selected staff who will understand the physical processes taking place in the equipment, monitor its integrity and good technical condition.

When incinerating different types of waste, it is necessary to take into account the morphological composition of the waste, the water content and gas formation during combustion. Experimentally, in small batches, select the optimal volume of the maximum load of the incinerator in order to avoid excessive ignition, smoke formation, and an uncontrolled set of temperatures.
What are the recommendations for the recovery of ferrous metals during waste recycling and disposal in the VOLKAN & HURIKAN incinerators? 14

Answer
The best available technologies for waste treatment involve the recovery of ferrous and non-ferrous metals from waste. The extraction of ferrous metals is done with a magnetic separator: the ash is placed on a conveyor belt or vibrating conveyor and all magnetic particles are attracted to a suspended magnet. The extraction of ferrous metals can be done when the raw waste comes out of the ash dump. Efficient extraction of ferrous metals requires additional treatment with intermediate grinding and sieving.

Useful components are extracted with an eddy current or magnetic separator. The technique is effective for particle sizes from 4-30 mm and requires an even distribution of waste on the conveyor belt. Non-ferrous metals are recovered after ferrous metals are extracted, particles are ground and sieved.

The approach feasibility is closely linked to the metal content of the waste arriving at waste treatment and disposal. This, in turn, depends on the collection mode and the pretreatment to which the waste is subjected before it is fed into the unit. For example, in areas with well-developed and successful separate household waste collection systems, quite small quantities of metals in waste may be found. Pretreatment of household waste to produce fuel from waste has the same effect.

Ferrous metals are recovered using a small amount of energy, and efficiency is increased by applying size pre-sorting, shredding and distributing the waste evenly across the magnet area. This involves the additional use of electrical energy.

Non-ferrous metals are separated by metal type and then remelted. As a result, the ash contains less metal and can be recycled into an inert secondary building material.

Technologically, it is possible to obtain noble and rare metals from copper electrolyte sludge based on oxidative roasting.

Certificates of conformity are issued based on the results of tests on ash dust samples. The supplier shall, on the buyer’s request, provide certificates of conformity with batches of fly ash dispatched from the place of generation.

If requested by the purchaser, ash sample test results are sent after test burns to the buyer as soon as they are available. Eco-Spectrum conducts a full range of research and develops recommendations for the further use of ash.

What are the recommendations and technical requirements for the characteristics of ash and residues from incineration in the VOLKAN and HURIKAN incinerators used for recycling 16

Answer

Recommendations apply to ash or other combustion products from combustion:

- household, industrial or commercial waste;

- sewage sediments or other newly generated waste;

- wood and wooden waste;

- rice bran;

- agricultural waste;

- sludge from the gas scrubbing unit;

- any combination of the above.

Ash disposal. The waste to be treated in the unit may contain refractory, non-combustible substances that pass into ash. Their presence affects the ash content: volume and quantitative chemical analysis. Thus, the amount of ash residue can be 3-50%, depending on the loaded waste composition. The output control serves to determine the physical and chemical properties and hazard class of the decontaminated material.

As SMR ashes and residues from waste incineration HS code 2621100000

After thermal waste decontamination of (incineration), secondary waste is generated according to the FCCW:

- 6 11 910 01 49 4 ash from burning sunflower husks;

- 6 11 910 02 49 5 ash from the burning of rice husks;

- 7 42 211 11 49 4 ash from the burning of bark and wood waste and sewage treatment sludge from pulp and paper production;

- 7 46 311 11 40 4 ash from the burning of dewatered sludge of domestic and mixed sewage is low-hazard;

- 7 47 112 11 40 4 ash from the burning of consumer waste in production, similar to municipal waste;

- 7 47 119 11 40 4 ash from the burning of consumption waste in the production, similar to municipal waste, mixed with industrial waste, including oily waste;

- 7 47 813 01 40 4 ash from the burning biological waste from the vivarium and laboratory animal waste;

- 7 47 821 01 40 4 ash from combustion of biological waste from animal housing, slaughter and processing;

- 7 47 841 11 49 4 ash from medical waste incineration, containing mainly silicon and calcium oxides;

- 7 47 911 11 40 4 ash from the combustion of waste paper, cardboard, wood and wood products, containing mainly calcium and magnesium oxides;

- 7 47 931 01 40 4 ash from burning paper, cardboard, wooden containers (packaging) from explosives, pesticides, agrochemicals and other chemical products;

The resulting scale (ash) after processing can form a secondary raw material. The resulting secondary raw materials can be used as a mineral additive or filler in the manufacture of heavy, light, cellular concrete, dry building mixtures, as well as mineral binders for the preparation of mixtures and reinforced soils in road construction. The final consumption of SMR will be: production of foam and gas blocks, ash bricks, paving stones, production of cements and dry building mixes of concrete and piece reinforced concrete products, drainage devices, tiles, production of waterproofing and soundproofing materials, mineral fiber, various composite materials, mastics, sealants, and paint and varnish products, act as a filler in road construction, runways, taxiways, parking lots in airports, in the construction of port facilities, to increase the seismic resistance of buildings and structures, reclamation of quarries, in the construction of landfills, landfill bunding, dumping in garbage dumps, tailings, sludge reservoirs, dams, industrial pools and channels; filling of mined out spaces with ash. (Appendix 2).

If the obtained ash is used for decontamination of the waste containing toxic and ecologically dangerous substances, pelletizing technology is applicable: mixing of 40-60 wt.% of ash, 10-20 wt.% of silicon oxide component of SiO₂ — 50-75%, Al₂O₃ — 530%, Na₂O — 5-20%, CaO — 1-10%, 20-40 wt.% of acid component. From the obtained mixture, granules are formed, powdered with dispersed refractory material, dried and heat-treated in two stages: for 10-30 min at 400-600 °С and for 1-20 min at 870-950°С. Technical result: increasing the strength, water resistance of the obtained non-toxic pellets of non-toxic form, and the suitability for safe burial or application. Such a method has been patented as a method of producing ash-filled polymer concretes when high-molecular-weight compounds, such as unsaturated polyester resin, are used as a binder. Such polymer concrete is characterized by high strength characteristics, resistance to chipping, products from it have a pore-free surface.

One way to process ash with a specific surface of 2000-4000 cm²/g, containing salts of heavy metals — cadmium, copper, lead and zinc, mixed with sulfur in a ratio of 1:1-1:2.5 and heated to mastic consistency, after which the mastic is poured into molds for making blocks, or fed to the machine for pelletizing. When testing the samples, in aqueous extracts, zinc, cadmium, copper was not detected, lead — 0.024 mg/l, the content of petroleum products did not exceed 0.1 mg/l, hydrogen sulfide is not released.

Acid ash should be used to partially or completely replace porous sands and reduce the average density of concrete. For structures of underwater and internal zones of hydraulic structures type IV acid ash should be used.

In general, the disposal of ash in the composition provides recycling into environmentally safe products up to 90% of the original mass of ash.

The use of ash as a reclamation agent for mine and quarry workings during mining for the purposes of environmental protection and sanitary and hygienic direction of their reclamation according to GOST 17.5.3.04-83.

At low pH values (less than 5) liming with calcium-containing reagents is used: calcium oxide CaO, calcium oxide Ca(OH)₂, and limestone flour (dolomite). At high pH values of initial raw materials (more than 8.5), deoxidation with Phosphogypsum is used. Sorbents and structurizers (pore-forming additives) are used to increase porosity and improve the structure of techno-soil.

The possibility of obtaining amorphous silicon dioxide (ASD) makes it possible to use the inorganic potential of rice husk as a raw material: SiO2 — 80 %, carbon C — 9 %, oxides (Fe₂O3 - 0.01 %, Al₂O₃ — 0.15 %, TiO₂ — 0.01 %, MgO - 0.4 %, CaO - 0.98 %, K₂O — 2.09 %, Na₂O — 0.07 %, Mn₃O₄ — 0.28 %, SO₃ — 0.8 %), moisture capacity — 2 %, obtained at high-temperature (600-800°С) influence on the rice husks in a vortex flow of hot oxidizing gas. It has high thermal insulation properties, high melting point, low bulk density and high porosity. It is used in the steel industry to slow down the cooling of metal by insulating its surface. The coating absorbs non-metallic inclusions (aluminum oxides) in the liquid steel.

Return the decontaminated soil into the economic turnover or the environment by improving its biological properties by introducing biogenic elements. Biogenic elements are applied in the form of agrochemicals — nitrogen-containing mineral fertilizers (ammonium nitrate, potassium nitrate, urea, phosphate fertilizers, potash) fertilizers included in the state catalog of pesticides and agrochemicals approved for use in the Russian Federation.

The heat or materials resulting from these technologies can be used for various purposes or not used if it is not profitable for economic or organizational reasons.

It is possible to get material SMR (ash, decontaminated soil) product quality certificate (voluntary certification).

Is it possible to get electricity from waste disposal? 17

Answer

It is possible to remove the generated heat energy not only by means of heat exchangers. The optimum solution considered is a combined heat and power generator that can utilize the waste heat of exhaust gas streams from 250°C to generate more than 600 kW of energy. The use of units in conjunction with modern thermoelectric generators (combined heat and power plants) eliminates the use of climate-damaging refrigerants as the working body using ethanol as the working body, in addition to the drive motor energy and highly efficient conversion of waste heat into electricity, compressed air, cooling.

Such a solution offers the user without affecting production:

•        produce demand-oriented energy: the necessary quantity and quality of energy;

•        higher efficiency: very low conversion losses;

•        useful heat that can be used for heating or drying/preheating;

•        useful heat can be converted into technical cold.

An alternative solution for heat generation can be the installation of a utilizing boiler, which converts the steam obtained into electrical energy. In addition, a condenser can be used for water cycling, or the use of waste steam to heat water at the enterprise. Then the exhaust gases if necessary, go to the gas scrubbing unit.

The sequence of processes for generating electricity by converting heat for this purpose is similar to that in diesel and gasoline power generators. Conversion of heat released during thermal decontamination into mechanical energy. Electricity is generated in the generator.

A popular type of generating set is its modification with autostart. The thermoelectric generator turns on automatically without operator intervention in case of an interruption of the circuit in the central power supply system. The equipment can be used:

•        as a backup power supply;

•        as the main supplier of energy;

•        for seasonal activation of the facility.

The recuperator unit makes it possible to heat water with the waste gases from the VOLKAN or HURIKAN Series to a temperature sufficient for heating the production facilities or for hot water demand in the plant.

Concentrated effluent from the gas scrubbing system and wastewater from process equipment washing can be used for ash cooling with steam removal to the firing unit.
Does Eco-Spectrum make heat recuperators for the incinerator? 18

Answer

A recuperator is a device for utilizing the heat of exhaust gases, in which the heat between the heat carriers is transferred continuously through a wall separating them.

Water pipe-in-pipe recuperator is a heat exchanger, whose operating principle is convective heat transfer from the flue gases flowing in the flue pipe of the incinerator (furnace) to the vessel (cavity) in which the coolant circulates.

Eco-Spectrum LLC produces recuperators, designed and manufactured in accordance with TU 28.25.11-001-37098548-2020.

The water recuperator is installed on the incinerator pipe. The water recuperator is bound by the customer with the necessary safety equipment.

The pipe-in-pipe recuperator should only be started up, directly operated and stopped after reading the operating manual (OM).
What is the thermal capacity of the heat recuperators in the VOLKAN and HURIKAN thermal decontamination complexes? 19

Answer
The use of the heat received from the operation of the thermal decontamination unit (complex) is a rational method of waste disposal (according to Federal Law No. 89).

In order to provide the recovery, it is necessary to complete the Unit with a heat exchanger. Shell-and-tube heat exchangers, element (section) heat exchangers, two-pipe heat exchangers of pipe-in-pipe type, twisted, ribbed, spiral, plate, plate-and-ribbed heat exchangers, and others are used.

When the maximum allowable operating pressure exceeds 0.05 MPa, the unit must be inspected and certified by TR TS 032 "On safety of overpressure equipment" and registered with Rostechnadzor.

According to calculations:

- VOLKAN Series: heat output in water or air — from 8000 kcal/h to 120,000 kcal/h; electricity generation — generator capacity from 3 to 25 kW.

HURIKAN Series: heat output in water or air — 8000 kcal/h up to 0.82 Gcal/h; power generation — generator capacity from 3 kW up to 250 kW.

HURIKAN R Series: heat output in water or air — 8000 kcal/h up to 5.16 Gcal/h; power generation — generator capacity from 3 kW up to 2,5 kW.

The data are approximate. Rated ambient temperature (air) +20°C, exhaust gas temperature + 200°C.

The heat output of water vapor at temperatures up to +200°C is equal to the heat output of air (water).

Recuperators are calculated and manufactured individually according to the specifications and the customer requirements, which takes into account the length of the heating duct, the area of heated rooms, etc.

Does Eco-Spectrum develop recommendations for the use of ash and residues from waste incineration as a secondary material resource (SMR)? 38

Answer
Eco-Spectrum develops recommendations for ash and residues from waste incineration, establishes methods for laboratory determination of physical characteristics, in order to determine the scope of application (production and construction).
The recommendations do not include coarse debris, only ash and fine fractional residues from waste incineration.

Recommendations are prepared on the basis of regulatory, normative, technical and design documentation, as well as on the basis of scientific, technical, educational and reference literature.
The entire process of waste management by stages, process cycles with the involvement of appropriate material resources in economic activities as secondary raw materials, with the main task of preserving and protecting the environment, human health and life is fundamental in carrying out such work.

Recommendations are developed individually for each customer of ECO-SPECTRUM based on the waste type or its mixture.
Does Eco-Spectrum develop any recommendations for thermal decontamination, are there any standards or requirements? 39

Answer
The main object of the recommendation in the requirements is resource conservation. The main objectives of the Standard development are to prevent the negative waste impact on the environment and human health by reducing the amount of waste produced and its maximum involvement in the economic turnover as a source of secondary material and energy resources in order to preserve and save primary natural resources, reducing the areas of waste disposal and their negative impact on the environment.

The recommendation subject is the management of production and consumption waste, in particular, obtaining energy resources and secondary material resources from ash and residues from waste incineration.

The recommendation aspects are: use of generated heat in the thermal waste destruction and technical requirements for the
characteristics of ash and residues from waste incineration intended for recycling.

Of course, the recommendations do not claim to solve all the safety problems of management of waste from the incineration of production and consumption waste, if any. It is the user responsibility to establish appropriate health, safety, and environmental procedures and determine the applicability of regulatory restrictions prior to the recommendation use.

Currently, thermal decontamination is only part of a comprehensive waste management system aimed at eliminating waste generated during human activities. Based on the principles of waste management adopted in the Russian Federation and the world as a whole according to Article 3 of Federal Law No. 89-FZ "On Production and Consumption Waste", the waste management policy is aimed at using the best available technologies to achieve performance with improved economic (lower cost compared to conventional) and environmental (higher environmental performance) characteristics, for this reason, the possibility of secondary benefit in decontamination is considered.

The developed recommendations are aimed at the practical support of the processes of wider recycling of ash and residues from waste incineration in the VOLKAN and NURIKAN units.

Recommendations are applied by ecologists, designers, engineers, municipal services, other end users interested in resource conservation, nature protection and ensuring occupational safety during collection and subsequent use of ash and residues from waste incineration with minimum loss of time, labor and financial costs, and causing minimal environmental damage. Recommendations developed by Eco-Spectrum LLC are unique, based on Eco-Spectrum own scientific and applied research, results of Eco-Spectrum activities, reference books and specialized literature, allowing to find the best solutions and recommendations.

What is the capacity of the VOLKAN 200 incinerator on the sovtol? 40

Answer
According to the data sheet of transformer waste with pentachlorodiphenyl, FCCW (Federal Classificatory Catalog of Waste) Code 4 72 120 01 52 1, the content in the waste sovtol-10 is 38.358%, metal content — 61.642%.

According to Information and Technical Handbook 52-2022 "Management of Wastes of Hazard Classes I and II", electrical equipment in the form of power transformers of various capacities may contain PCBs of the following composition: - sovtol-10 (90% PCBs and 10% 1,2,4-trichlorobenzene). The mass percentage of chlorine in pentachlorodiphenyl (PCB, chemical formula C12H5C15) and trichlorobenzene (C6H3C13) is 50 to 60%.

In accordance with SEER Conclusion No. 5, to ensure the optimum technological process in the presence of a state educational institution, it is necessary to ensure the content of halogenated organic substances (chlorine) in the range of 1-15%. Taking into account the approximate content of halogenated organic substances (chlorine) in transformer waste with PCBs 50-60%, at a nominal unit load of 20 kg/h, the unit capacity will be: for drained sovtol-10 — about 50 kg/h when mixed with other substances and materials to obtain a concentration of chlorine 1-15% and taking into account the approximate content of halogenated organic substances (chlorine) in the transformer waste with PCBs 50-60%".
How do you clean acid-forming pollutants? 41

Answer
Wet systems (wet scrubbers, TYPHOON Scrubber) are used for cleaning of acid-forming pollutants, which provide reduction of SO2 concentration in exhaust gases by decontamination with aqueous alkaline solutions (NaOH, Na2CO3, Ca(OH)2, etc.). Alkali dosing is necessary to maintain the pH value of the treated water in the range of 6.5 to 8.5. In addition, pH values below 6.5 lead to significant wear and tear due to the acidic environment. The actual amount of alkali needed to raise the pH from 6 to 9, determined during the test burn, is approximately 8 liters of 10% NaOH solution per 1 m3 of purified water. The actual value of the reagent consumption depends on the incinerated waste and is always individual. Alkali is dosed until the desired pH value is reached.

What is the process of waste decontamination in the HURIKAN rotary incinerator? 54

Answer
The waste is loaded into the receiving hopper, from which it enters the screw conveyor and is fed into the rotating main chamber and passes through the burner flame. Under the high temperature influence, the combustion begins in the air oxygen environment.
Waste is moved inside the rotating main chamber (combustion chamber) of the incinerator, where it is exposed to high temperatures. As a result of waste combustion, flue gases are formed and go from the main chamber to the secondary chamber, and the ash comes to the ash collector - the system of automatic ash discharge.
In the secondary chamber (afterburning chamber), organic compounds of flue gases not destroyed in the main chamber, are burned off at high temperature by holding the gases for at least 2 seconds at high temperature (at least 850C)
The gas heated to a high temperature from the secondary chamber enters the heat exchanger, lowering its temperature to a value, at which it is possible to operate the gas scrubbing system.
The flue gases from the heat exchanger are directed to the gas scrubbing system, which consists of a cyclone filter with an additional dry injection system. Dust particles, sulfur dioxide, hydrogen chloride, heavy metals and organic impurities are captured. Flue gases are emitted into the atmosphere in scrubbed form through the chimney.
Is there any waste left over after gas decontamination in the HURIKAN incinerator? 55

Answer
Due to the unique recycling cycle system in conjunction with the incinerator, developed by Eco-Spectrum LLC, waste generation during operation can be eliminated, thereby reducing the level of impact on the environment.
The water treatment system consists of the following interrelated structures:
- tank for water supply to the gas scrubber;
- recycling water treatment tank, where the effluent is settled and treated, and the treated and cleaned liquid is fed back into the gas treatment system via a water supply tank to the gas scrubber.
The water treatment system can be equipped with a preparation and dosing station that allows to prepare reagent solutions and automatically feed them into the system, as well as monitor their content using sensors.
The water treatment system can be equipped with waste water cooling devices to reduce evaporation losses during operation of the gas treatment system.
The wet gas scrubbing system compared to the dry gas scrubbing system is preferable due to greater efficiency, the possibility of sharp gas quenching to prevent recombination of PCDD/F, minimization of the amount of by-product produced by the gas scrubbing system, lower power consumption.

Can Eco-Spectrum advise on the choice of magnetic separators, which separators have the best characteristics? 63

Answer

Sorted metals have one of the highest resale prices in the recycled material market.

In addition, it is considered much more economically viable to use recycled metal instead of mining it and remelting it for further use.

The eddy current separator for non-magnetic metals allows the separation of nonferrous metals. Due to it, conductive metals acquire a trajectory different from the inert fraction, which ensures the separation of non-ferrous metals. The eddy current separator is capable of separating non-magnetic metals such as Al, Mg, Cu, Ag, Zn, Sn, Pb from inert non-conductive materials such as glass, wood, plastic, rubber, paper, etc.

The magnetic separator allows to separate magnetic metals from the inert fraction. Magnetic separators consist of a magnet surrounded by a rotating conveyor belt.

Eco-Spectrum can develop a complex project, including equipment for metal sorting. We work with magnetic separator manufacturers all over the world and can offer the best solutions. Eco-Spectrum manufactures conveyor belts, separators, drum screens and other sorting equipment for sorting and disposal.

What to do with hazardous waste? 65

Answer
There are some types of waste not allowed to be sorted because of their hazardous characteristics or low marketability as secondary raw materials. These include: medical, chemical, textiles and other types of waste.

However, this does not mean that this waste should be sent to landfill. The best solution is to thermally decontaminate such waste by incineration, given the importance of scrubbing the flue gases to preserve the environment, with the possibility of using the scrubbed gases to produce heat and electricity.

Eco-Spectrum offers a wide range of incinerators with gas scrubbing systems with emission thresholds equivalent to Directive 2010/75/EC of the European Parliament and Council dated 24 November 2010 “On industrial emissions”.
Biological soil or compost? 66

Answer
Biological soil is the product of composting, which produces fertilizer.

The concept of bio-soil production is to periodically intermix the compost, resulting in material that can be sold to fertilizer companies.

Made of organic waste, it already contains many nutrients making it easy to mix the biosolids with additives to achieve the right level to produce the desired type of fertilizer.

According to the European Commission, more efficient use of nutrients means more sustainable and less resource-intensive agriculture, as well as less damage to local water sources.
Am I correct in assuming that water treatment is used after wet scrubbing, which allows for waste-free disposal? 67

Answer
The flotation technology is pressure flotation with partial recirculation of treated effluent to produce a flotation mixture. This method allows to clean wastewater from petroleum products and their processing, fats and oils, products of organic synthesis, surface active substances (surfactants), fine suspended solids, activated sludge from biological treatment facilities, etc. Flotator operates in the flow-through mode. Part of the treated water is fed by the circulation pump to the saturator; from the saturator, air-saturated water is fed to the flotation chamber inlet and mixed with the source water. In the flotation chamber, due to a sharp pressure decrease, dissolved air is released. Flocculated impurities (flotation foam) are continuously removed from the water surface by a scraper mechanism into a “dirty pocket” and drained away. The sludge is collected in the conical part of the flotator and sent for incineration, providing a closed cycle and waste-free disposal.
What does the automation and instrumentation system include? 68

Answer

What are the benefits of ashes after incineration, where can ashes be used after incineration? 81

Answer

Ash disposal. Waste sent for processing may contain refractory non-flammable substances that pass into ash. Their presence affects the ash content: residue mass and composition. Thus, the ash residue amount depends on the loaded waste composition. Outlet ash control is necessary to determine the physical and chemical properties and hazard class of the decontaminated material.

Earlier studies of ash show is composition domination by silicon and calcium oxides, which implies that the main area of ash application can be the construction field — use as an inert building material.

How does Eco-Spectrum prevent recombination of dioxins and furans? 86

Answer
When solving the problem of bringing the sulfur dioxide level to the MPE requirements and quenching of flue gases to prevent the recombination of dioxins and furans, decisions are made to use a wet gas scrubbing system complete with a Venturi scrubber with water spraying and an additional injection of an alkaline reagent. In the case of dioxins and furans, their presence in flue gases is due to their recombination in highly dusty gas in the temperature range from 200 to 450°C. Therefore, in this case, in order to avoid this process, it is necessary to avoid dust and air mixture in this temperature range for more than 0.7 seconds. Abrupt gas cooling (quenching) and dedusting prevent the formation of dioxins and furans, meeting the MPE requirement in emissions not exceeding 0.04 ng/m3. For sulfur and chlorine-containing waste, there are several options for flue gas scrubbing from acid gases (sulfur dioxide and hydrogen chloride), and the efficiency of the wet gas scrubbing system compared to the dry one is higher.

Advantages:
- higher scrubbing efficiency than for dry ones;
- gas quenching with abrupt cooling, which prevents recombination of dioxins and furans;
- less waste after the scrubbing system than for dry system.
What are the advantages of a freestanding afterburning chamber for VOLKAN and HURIKAN incinerators? 87

Answer
The advantage of all Eco-Spectrum incinerators is the freestanding combustion chamber, so the combustion chamber is accessible from three sides. This provides easy and safe operation, the incinerator body is not exposed to thermal shock when opening the cover, there are no obstacles for loading mechanisms or machinery when bringing and loading waste.
Eco-Spectrum engineers have developed removable hydraulic bucket loaders with a tipping function, making loading much easier.
What material is used for lining the cover of VOLKAN and HURIKAN incinerators? 88

Answer
The chamber cover is a moving part of the incinerator, and on a large perimeter, is created in addition to the thermal load dynamic. Therefore, an insulating lining under its weight over a large perimeter must meet the following technical requirements:

1. Light weight
2. Fire resistance up to min. 1100°C
3. No contact of fixing metal material with hot gas/flame
4. Durability

In the production of linings for incinerator covers, Eco-Spectrum uses high quality lightweight insulating materials of European quality that allow the unit to be serviced without great physical effort by personnel. At the same time, the cover lining provides protection for the metal body of the cover, which eliminates its deformation and destruction.
How does the location of the burners affect combustion? 89

Answer
The chamber burners in VOLKAN incinerators and some HURIKAN models are located in the end walls of the combustion chamber at an angle of 25 degrees, which allows the burners' flames not to cross, cover the entire loaded material with the flame, achieve the most efficient (high-quality) material combustion/incineration.
What is the usable volume of the combustion chamber? 90

Answer
Waste must not block process openings: burner ports, gas passages. The combustion chamber must leave a volume for the combustion products. When the chamber is fully loaded, the burner flame will go out due to a lack of oxygen and in this case, the incinerator will smoke from under the cover. Useful volume is a part of the internal space of the chamber, in which it is possible to maintain the specified conditions at the exhausted mode within the specified tolerances.
The HURIKAN 150 chamber incinerator is designed for the high-temperature thermal destruction, decontamination and disposal of industrial, medical and biological waste.
The waste is loaded into the loading unit or through sliding covers for oversized waste, after which, it enters the main chamber.

The main chamber (combustion chamber) is a welded box-type structure made of sheet steel and reinforced with stiffening ribs. The chamber lining is presented by two layers: the first (main) is heat-resistant concrete with operating temperature up to 1400°С, it takes the main heat load; the second (intermediate) is fiberglass refractory plate with operating temperature up to 1400°С, it additionally protects the metal body from high temperatures, allows to operate the installation in case of damage of concrete lining.

The burner units (BU) of the main chamber are installed in two rows. The upper row of BUs provides waste ignition and combustion, as well as maintains the decontamination temperature automatically in the specified temperature range. The bottom row of BUs provides waste ignition, minimizes mechanical underburning, provides decontamination of liquid waste, and maintains the decontamination temperature automatically in the specified temperature range. Due to these design solutions, uniform and complete thermal decomposition of waste is possible, and the minimum possible yield of ash residue is achieved. Then, the flue gases and decomposition products enter the secondary chamber.

The secondary chamber (afterburning chamber) is a welded box-type structure made of sheet steel and reinforced with stiffening ribs. The chamber is lined with high-temperature fiber, which provides a reduction in thermal losses of the chamber and reduces the structure weight. In this chamber at temperatures above 900-950°C, afterburning of unburned in the main chamber particles and gases (oxidation of CO, decomposition of dioxins and furans, etc.) occurs. The chamber volume is calculated based on the unit capacity and the morphological composition of the waste, which allows to hold gas for more than 2 seconds, ensuring quality decontamination in accordance with Directive 2000/76/EC of the European Parliament and of the Council on "Waste incineration", Brussels, 4 December 2000, European Parliament and of the Council of the European Union. The secondary combustion chamber burner units maintain the afterburning temperature automatically within the specified temperature range.

To improve the operation quality (to reduce the pollutant concentration in the emissions) after the secondary chamber, the flue gases go to the wet gas scrubbing system. This system is represented by the TYPHOON scrubber (Venturi scrubber) high-pressure direct-flow Venturi gas scrubber. In high-speed gas scrubbers, the main factor ensuring gas scrubbing is the water feeding into the high-speed dusty gas flow, which contributes to thorough water dispersion and subsequent washing of gas with water in the turbulent mode of gas flow. High purge gas velocities are provided by Venturi tubes. In general, TYPHOON scrubbers are a combination of Venturi tubes and downstream drift eliminators. Water enters the fastest part of the Venturi tubes (in the confuser). The scrubber has a water supply with the reagent introduction to decontaminate the gaseous impurities contained in the flue gases. Also in the process of high-speed gas flushing, the gas is abruptly cooled ("gas quenching") — this process prevents the recombination of highly toxic dioxins and furans, this method of "gas quenching" in the TYPHOON scrubber is the most effective and least energy consuming (water has the greatest heat capacity and heat of phase transition compared to air or other easily accessible heat carriers).

The gas treatment system requires a water treatment system. This system supplies water to the Venturi pipe for spray irrigation, diverts contaminated water from the cyclone drift eliminator, cools and scrubs the water, prepares and delivers water again to the Venturi pipe. The system make-up is insignificant and is associated with evaporation losses in the gas scrubbing system.

Scrubbed flue gases are removed from the system through the gas ducts due to the operation of a centrifugal high-pressure fan (smoke exhauster), which overcomes the resistance of the entire system and provides a nominal flow of flue gases.

n case of emergency situations in the gas scrubbing system, water treatment system or other incinerator is equipped with a bypass and emergency chimney to ensure, if necessary, removal of combustion products from the unit.

The basic operating parameters are controlled with the automation panel. It is located in the unit service area, which ensures efficient work of the operator and full control over the decontamination process. Built-in archiver and remote GSM connection allows on-site and remote control. 91

What is the capacity of recuperators produced by Eco-Spectrum? 93

Answer
The capacity of gas-to-liquid (gas-to-air) recuperators can vary from 10 kW to 3MW, depending on the incinerator model, recuperator purpose and afterburning chamber temperatures maintained.
What is the operating principle of TYPHOON wet scrubbing system from Eco-Spectrum? 94

Answer
Due to the high temperatures of waste disposal, the dry gas scrubbing line must, first of all, include a gas-air or gas-water recuperator (heat exchanger, cooler). Its main task is to ensure that the incoming gas temperature drops to a level safe for the downstream equipment operation. Gas-air recuperators can be equipped with fans for greater efficiency.

The gas scrubbing line itself must have at least two stages: coarse and fine scrubbing (Fig. 1).

Fig. 1 Process diagram of the wet gas scrubbing system of the incinerator

The first stage can be represented by cyclones (battery cyclones, dust collecting chambers, inertial dust collectors) for settling the coarse fraction of suspended particles. The second stage can be represented by gas scrubbers (sprayed gas ducts, flushing chambers, hollow and packed scrubbers, Venturi scrubber, foam and barbotage scrubbers, etc.), serves for fine gas scrubbing from suspended particles, as well as for decontamination of gaseous impurities. The number of apparatuses and the reagents used in the irrigation liquid depend on the composition of the gas to be scrubbed. When using Venturi scrubbers to scrub gas with a dust content up to 30 g/m3, it is possible not to install a recuperator and the first stage (cyclones, etc.).

Next, the gas must be scrubbed of dripping moisture. Centrifugal drift eliminators, plate drift eliminators and other devices can be used to reduce the moisture content in the scrubbed gas.

The required volume of pumped gas, as well as overcoming the resistance of the entire gas-scrubbing system, is provided by installing one or more centrifugal fans.

If necessary, the system can be equipped with an absorber.

The first stage can be represented by cyclones (battery cyclones, dust collecting chambers, inertial dust collectors) for settling the coarse fraction of suspended particles. The second stage can be represented by bag (fabric) filters (fiber and granular filters, electrostatic precipitators, ceramic filters), serves for fine gas scrubbing from suspended particles.

After dedusting, the gas is scrubbed of the remaining gaseous impurities. Catalytic and adsorption filters are used for this purpose, depending on the impurities.

The required volume of pumped gas, as well as overcoming the resistance of the entire gas-scrubbing system, is provided by installing one or more centrifugal fans.

If necessary, the dry gas scrubbing system can be additionally equipped with a dry sorbent injection system to decontaminate gaseous impurities.
The TDU has no lining layer to provide and maintain the stated temperatures in the chambers. Even in the case of structural "pipe-in-pipe" design, the inner tube will be exposed to temperatures that exceed the thermal resistance of the material, which will cause significant deformation, loss of bearing capacity, corrosion, and burning. Steel AISI 430 (lining chambers) is used up to +850°C, with prolonged use in the range of +400°C - +600°C becomes brittle, fragile and requires annealing for further use.
Significant heat losses not only increase fuel consumption to maintain decontamination temperatures, but also expose other structure elements to heat, degrading performance, reducing load-bearing capacity, increasing wear (supports, bearing assembly, etc.).

The HURIKAN 2000R incinerator has a double-layer lining of both the combustion and the afterburning chambers.

The combustion chamber lining (together with the loading and unloading unit) consists of:

1. Insulation of internal walls of the furnace body with fiberglass refractory slabs is arranged to reduce heat loss, ensure stable temperatures, minimize fuel consumption to maintain combustion, avoid high thermal loads on the metal body, increase efficiency and the service life of the unit. Heat resistance up to 1260°C.

2. Monolithic concrete with anchoring system provides resistance to mechanical loads during rotation and waste loading, extends lining service life without repairs, operation at high temperatures above 800°C, respectively, increases the unit performance. It also heats the exhaust gases in the secondary chamber for further thermal treatment (afterburning) at a temperature of at least 850°C to increase efficiency by accumulating heat, as well as minimizing fuel consumption. Heat resistance up to 1300°C.

The afterburning chamber lining consists of
1. Fiberglass refractory ceramic blocks designed to the secondary chamber configuration are installed by Z-block method that eliminates the contact of fixing materials with hot gas and open flame. This technology allows for long lining life, and the lining density, characteristics and thickness reduce heat loss and thermal load, correspondingly increasing service life and efficiency by maintaining high temperatures without heat loss. Heat resistance up to 1260°C.
2. High temperature alumina mastic provides additional protection for fiberglass blocks against thermal stress and abrasion. Heat resistance up to 1700°C.

What does the capacity of a waste incineration unit depend on? 97

Answer
The unit capacity is determined by the generated volume of flue gases, the time of its holding in the afterburning chamber and, accordingly, the temperature maintained in the afterburning chamber.

The combustion rate is directly related to the temperature set. When the material burns, thermal energy is released, which causes the temperature in the chambers to rise. To ensure stable temperatures in the waste incinerator, the combustion rate should match all the technical parameters of the main chamber (size, shape, volume, etc.).

The combustion rate of materials is usually estimated by the average speed of flame propagation through the combustion chamber space, expressed in meters per second. The combustion rate depends on the composition and degree of gas mixture swirling, compression ratio, combustion chamber shape, and other physical and technical parameters.

The combustion rate also depends directly on the diameter of the transitions and the combustion chamber volume. The gas swirling projection also depends on the position and angle of the burners in the chamber.
The combustion rate depends on the area of the materials to be burned.
98

Answer
The gas scrubbing system of THD unit is represented by a cyclone and a wet hollow scrubber. Based on the maintained temperatures in the afterburning chamber and the absence of any heat exchangers, it can be concluded that the cooling of flue gases before the cyclone is due to the dilution of combustion products with atmospheric air. This requires the installation of a more productive gas scrubbing system. Otherwise, the decontamination temperatures do not actually match the stated temperatures. The wet hollow scrubber is the cheapest, less energy-consuming solution in wet scrubbing systems, and therefore, less effective than other options.

There is no water treatment system in the sense that it should be. There is no reagent dosage as such. The effluent is essentially untreated and re-fed to the scrubber for irrigation. There is also no cooling in the system, the effluent temperature during operation gradually increases, and the scrubbing efficiency decreases. The sludge is discharged manually.

The gas scrubbing system of HURIKAN 2000R incinerator is represented by TYPHOON scrubber. This scrubber operation is based on the use of a Venturi tube as the most effective gas scrubbing device. Flue gases are cooled from 1200°C to 150°C by the differential pressure and supply of irrigation liquid. Cooling occurs at flow rates of up to 150 m/s in a fraction of a second, providing a "gas quenching", preventing recombination of dioxins and furans. The use of nickel alloys on the Venturi pipe inlet allows the system to operate at flue gas temperatures up to 1200°C. The TYPHOON scrubber, due to its high resistance, makes it possible to effectively clean the flue gases not only from micron and submicron dust, but also from chemical pollutants even when using ordinary potable water as an irrigation liquid.

The water treatment system of the HURIKAN 2000R incinerator recycle cycle cools the gas scrubbing system effluent, purifies the effluent, and feeds the purified and prepared liquid back into the gas scrubbing system. Preparation and dosing station allows to prepare reagent solutions and automatically feed them into the system, as well as control their content. The generated sludge is automatically fed to the incinerator for decontamination, completely eliminating waste from the gas scrubbing and water treatment system. The system is supplied in insulated, heated containers that allow the unit to operate at low temperatures without the risk of system "defrosting".
How to compare the performance of TDU 500 and the HURIKAN 2000R? 99

Answer
According to the State Environmental Expert Conclusion, the TDU unit, based on the critical temperatures of the afterburning chamber, we can conclude about the operation in the temperature range from 1000 to 1300°С. The combustion chamber volume is 22 m3. Exposure time is 4 sec. Under these conditions, the TDU unit is designed for decontamination (afterburning) of not more than 4000 nm3/h of flue gases. HURIKAN 2000R incinerator, according to the State Environmental Expert Conclusion, decontaminates flue gases from oil sludge combustion in the afterburning chamber at a temperature of at least 850°С. The combustion chamber volume is 25 m3. Exposure time of 2 seconds according to Directive 2000/76/EC of the European Parliament and of the Council on waste combustion, Brussels, 4 December 2000. Under these conditions, the HURIKAN 2000R incinerator is designed for decontamination (afterburning) of no more than 10,000 nm3/h of flue gases.

The HURIKAN 2000R incinerator has a capacity of more than twice that of the TDU unit, provided that the process regulations and guidance documents are followed.

Do I need a license to burn waste generated in my own production and use the generated heat? 104

Answer
According to the law "On Licensing of Certain Types of Activities", activities for the collection, transportation, processing, disposal, neutralization, disposal of waste of hazard classes I-IV are subject to licensing. Thus, the planned activity falls under the definition of "disposal" and is subject to licensing.
Which category of land is suitable for the disposal site? 105

Answer

If the planned site does not correspond to the intended purpose, the transfer of land and land plots is allowed in cases defined by legislation.
How to choose an incinerator? 106

Answer

When choosing an incinerator, it is necessary to follow several mandatory rules.
In fact, we need to calculate two main parameters that we need to burn a particular type of waste. Incineration rate and waste fraction (size at one-time loading).

1. Type of waste (biological, wood, oil-containing, medical, etc.). The required burning rate depends on this parameter. Each waste burns differently!
2. The volume of waste per day in kilograms. This parameter also affects the burning rate.
3. Working shift in hours.
4. The size of the waste fraction in centimeters. This parameter will determine the required size of the boot window.

Here is an example of how you can choose an incinerator for a particular waste.

1. Type of waste - Biological (gastrointestinal)
2. Volume per day - 1000 kg
3. Working shift - 24 hours
4. Size - 1m3 = 0.7 kg of gastrointestinal tract

It turns out that in this case VOLKAN 750, VOLKAN 500. 1000 kg / 24 = 42 kg per hour + Fraction volume and morphology of waste (the gastrointestinal tract is very wet waste and a more productive incinerator is needed) is suitable for us.

Is it possible to dispose of chemical waste in an incinerator? 107
Answer

There is no single way to destroy chemical waste, there are 6 ways of disposal, which are used depending on the composition of the scrap.
1. Neutralization makes it possible to process harmful waste into safe ones due to various chemical reactions. For example, the hydrolysis of alkalis, which is applicable in the neutralization of poisons and pesticides.
2. Thanks to chlorination with oxidation, it is possible to neutralize substances by 99.99%. The procedure takes place using calcium, chlorine, sodium and hydrogen peroxide necessarily in water.
3. Alcoholism is a method of neutralization of chemical waste using chemical alcohols and mono-ethanols.
4. The simplest and cheapest way to destroy waste is the thermal method. As a result of the reaction, the chemical composition of the materials is completely destroyed, followed by their combustion.
5. Thanks to the distillation method, it is possible to split waste to displace liquids from them that participated in the initial reactions. After such splitting, the liquids can be reused.
6. The method of biological treatment of chemical waste has been poorly studied, it is used only in small factories.
Is the incineration of medical waste an acceptable method of disposal in accordance with the legislation? What methods and methods of neutralization (destruction) of medical waste are generally used? 108

Answer

Methods of medical waste treatment

In most countries that have ratified the Basel Convention of 1992, the rules and regulations for the disposal and transportation of medical waste are based on its provisions, which involves the use of technologies leading to the destruction of about 90% of medical waste and disinfection, followed by the disposal of the remaining 10%. At the same time, many countries, including Russia, still use the method of disposal in special landfills with preliminary disinfection for the disposal of most medical waste.

In the modern world, the main methods of medical waste treatment are:

Chemical disinfection

Chemical disinfection is most often performed using chlorine-containing substances. Chemical disinfection is often combined with mechanical processes, such as grinding or dissolving, to ensure complete penetration of chemicals.

Incineration using incinerators

Incineration is a controlled process of incineration of medical waste in a special furnace (incinerator). Waste intended for incineration in an incinerator cannot be sorted, so all waste is completely destroyed.

Steam sterilization under pressure and at a temperature of more than 100 ° C using autoclaves

Autoclave is a device for steam sterilization under pressure and at a temperature of more than 100 °. The autoclave is used for sterilization of dressings, linen, tools, dishes for bacteriological laboratories, nutrient media for growing microorganisms, etc. Autoclaves can also be used to sterilize medical waste before disposal in a landfill.

The principle of operation of the autoclave is based on an increase in the boiling point of water with increasing pressure.

Medical waste that has been disinfected in an autoclave must be further processed - compressed, grinded or crushed, so that the waste is unidentifiable and cannot be reused for other purposes. After sterilization and compaction, medical waste can be combined with household waste and disposed of in a common landfill.

Using microwaves

The use of microwaves for disinfection of medical waste is one of the recent innovations in this field. Microwave processing can be carried out both stationary and on mobile objects. For this type of disinfection, the waste is usually pre-crushed, then mixed with water and exposed to microwave radiation. The heat and steam generated during processing ensure uniform heating of all waste and effectively neutralize all biological preparations. Shredding reduces the volume of waste by up to 80%, while recycled waste can be disposed of in a conventional landfill.
An alternative method of sterilization of medical equipment, materials and medical waste is sterilization using ionizing, radioactive or infrared radiation
The sterilization effect of ionizing radiation is the result of exposure to the metabolic processes of the cell, while radioactive and infrared radiation, high-frequency vibrations exert their bactericidal effect with the help of heat developed in the treated object. Not all medical waste can be sterilized in this way (some microorganisms are radiation resistant). The risk of personnel exposure, although minimal, is also a disadvantage of this method.
What Federal law regulates the rules for handling medical waste? 109

Answer

At the moment, there is no separate federal law on medical waste in Russia, where the concept of "medical waste" would be clearly spelled out, rules for their collection, temporary storage, transportation, burial or destruction were contained, responsibility for the execution of each of the stages was determined, as well as measures applied in case of violations.

The rules for the treatment of medical waste are regulated by sanitary rules and norms N2.1.7.2790-10 of December 12, 2010 "Sanitary and epidemiological requirements for the treatment of medical waste".

What is more efficient, more profitable? Solid waste recycling or incineration? 110
Answer

Recycling About 40-50% of MSW are subject to repeated processing with the help of special technological equipment. The list of valuable raw materials includes the following types of waste:
- all types of metal
- glass
- polymers yarn
- and fabric products, paper
- tires, rubbers
- old asphalt pavement
- organic household and agricultural waste
All of the above materials can act as secondary raw materials after the processing process. Then they gain a second life in the form of products used in various spheres of human life.

Incineration is the most efficient way of disposal for all types of waste – solid, liquid and gaseous. It is carried out under the influence of extremely high temperatures exceeding the mark of 1000 ° C. The low-temperature combustion process is dangerous for the environment, as a result of which this method is being replaced by new technologies.

Burial is one of the simplest and cheapest options for waste disposal. Burial can be carried out on specially allocated land plots - landfills, quarries. This method of garbage disposal is ineffective and unsafe for the environment.

Result:

The prospects for generating income from the removal, storage, processing and incineration of garbage depend on their initial investments and the list of services provided. Only the collection and removal of solid waste on one unit of special equipment, which will regularly serve 6 - 8 points, can bring up to 6 thousand net profit per night, and 1 kilogram of solid waste in the cost of incineration costs is not more than 1.5 rubles. If there is not one machine, but several incineration plants, if there is at least one sorting line, it will be possible to process valuable scrap or at least just sort it, burn the "tails" after sorting, then the level of income from solid waste disposal activities will increase many times.
In combination, several methods can give maximum efficiency and economic benefits.
