Waste is one of the major challenges which modern world is facing today. Every year billions tones of waste are generated and these amounts are rising steadily.

Some major wastes which affect our environment are:

• Municipal Solid Waste (MSW)
• Different types of plastics
• Old tyres and rubber
• Auto Shredder Residue (ASR): plastics, rubber, fabrics, wires, etc.
• Organic waste: wood chips, saw waste, oil sludge, paper pulp sludge, poultry litter
• Medical waste from hospitals
• Electronic waste: computer boards, cables and wires

Wastes such as MSW, electronic waste, scrap tyres are currently either difficult to recycle or not 100% recyclable, while other waste such as medical waste is not recyclable and shall be disposed. Another typical example is goods packaging (e.g. food) when plastic attached to other materials (aluminum / polymer laminate). This laminate is inseparable from paper at the recycling facility. All these cases result in either incineration or landfilling.

On this website you will find the economically and ecologically viable industrial solutions of the different waste problems.

Brief summary of our core business:

• Waste-to-energy: pyrolysis as a source of bio fuel /green electricity
• Pyrolysis of toxic/medicine waste
• Pyrolysis of biomass and electricity production
• Pyrolysis of sewage/animal/paper sludge
• Pyrolysis: treatment of the decontaminated soil (oil, PCB, dioxin, mercury)

We perform turn-key projects (from a design phase to commissioning of the units) of the advanced proprietary waste-to-energy systems.

OUR GOALS: Practical implementation of the commercially proven environmental friendly and economically viable technologies:

• Stop polluting the environment
• Recover value from waste
• Decrease gas emissions
• Do not use food resources for energy production

With an increase in population, urbanization and technology advancement, the amount and type of waste generated by various sectors is rapidly increased, causing negative impacts on health and the environment.

Pyrolysis is the thermal decomposition of waste into gas and solid phases in the absence of the external oxygen supply. The process takes place under the temperatures typically around 500 C. The gaseous product of pyrolysis can undergo the following transformations in downstream processes:

• cooling down followed by oil condensing; liquefaction is applicable for a limited number of feedstock, such as plastics or rubber
• cracking and cleaning in order to be used as fuel in a gas engine; pyrolysis gas conditioning is a complicated problem and additional drawback is that further treatment of the pyrolysis char will be performed at the high temperatures around 1500 C
• secondary combustion and generation steam in boiler, which consequently will be sent to steam turbine to generate electricity

Some of the advantages of pyrolysis are that the pyrolysis process is relatively insensitive to its input waste, combustion products associated with the burned solid waste are not generated, and dioxins formation can be efficiently prevented.

Pyrolysis plants can be designed to operate either in batch or continuous mode

Batch pyrolysis system is usually implemented for smaller capacities.   The process cycle consists of several stages: a) loading waste, b) heating-up the system,  c) pyrolysis, d) cooling down the system, e) unloading products.

Batch system is used for scheme with oil condensing.

Batch process requires quite extensive manual labour. 

In spite of relatively low initial investments these units are less economically viable comparing with the continuous pyrolysis units.

We do not deliver pyrolysis batch systems anymore.

In Modular Pyrolysis Steam Cycle (MPSC) system waste is thermally degraded in a rotary kiln using an indirect, external source of heat, at temperatures of 400°–600°C in the absence of free oxygen supply. The volatile portion of the feedstock is thermally decomposed, producing syngas which is sent into a boiler, producing steam for power generation, with the flue gas treated in an emission control sub-system. Char from pyrolysis kiln is further treated to generate extra syngas to be used in the process.

The pyrolysis plant consists of several functional modules such as pyrolysis, energy recovery, electrical energy generation, gas cleaning, etc. implementing pyrolysis process with coupled conventional steam-cycle.

The plant performance is related to the composition of feedstock input (calorific value and moisture content). Average mixed waste content in the input varies. Due to the built-in design features, the MPSC system successfully accommodates sudden fluctuations in the waste quality from its average value, which occur within the facility.

Pyrolysis plants implementing oil recovery can also operate in continious mode

Pyrolysis has a number of important advantages over incineration.

• The pyrolysis system for treatment of MSW and other wastes demonstrates excellent practical performance in controlling the emission of harmful substances such as dioxins with levels dramatically lower than regulation values.
• The pyrolysis facility is self-sustainable, i.e. fuel is required only for start-up operations. Steam and/or electricity generated during operation is further supplied outside of the facility to the customers.
• The pyrolysis plant does not produce waste water effluent from the gas cleaning system. Along with this obvious environmental advantage it also makes the system less expensive.
• Another environmental aspect is the reduction of the residuals to be sent for landfill disposal. Some remaining non-toxic ashes can also be used in the building industry.
• Recovered Metals are non-oxidized and can be further used.
• Can treat both low calorific and high calorofic waste.

Municipal solid and industrial waste, as well as sewage sludge are generated in large amounts.

MSW pyrolysis plant can treat 

• fresh (unsorted) MSW
• sorted (high calorific) MSW
• MSW from landfill dumps (with soil)
• mixture of MSW with other waste, e.g. an industrial waste.

System performance depends on waste parameters: typical pyrolysis plant with the capacity 21 tph (daily treatment of 500 tons) of unsorted MSW generates 12-13 MWh of electricity, i.e daily about 300 MWe (gross). The system can also be designed to generate heat for a district heating/hot water supply.

Sewage sludge generated by waste water treatment, occupies large areas when it is sent to landfilling. Usage of sludge as fertilizer is limited due to the potential contaminations with heavy metals, pathogens, parasites, seeds of weeds. There are also handling problems due to odour and high water content. Sludge volume decreasing by drying or incineration besides other issues require high fuel consumption. Pyrolysis of mechanically dewatered sludge eliminates problems of contamination with bio-substances and decreases volumes of sludge. Additionally energy is generated without external fuel supply to the process.

Example of treatment of 350 tpd of sewage sludge with moisture content 65- 70% after mechanical filtration: the remaining ash constitute ~ 15% of the dewatered sludge. This self-sustained facility will generate ~ 23 GW of electricity on annual basis.

Treatment of oil sludge represents a significant expense. Tens of thousands of tons of oil sludge are generated annually from oil production, storage, refining, and transportation. The oil sludge related problem is also caused by leakage at oil tankers and oil rigs, resulting in oil contaminated sand and water polluted with oil sludge.

Proper treatment of oil sludge is essential since these waste materials are hazardous to human and environment.

The design specifications determine configuration of the pyrolysis system, i.e. whether to proceed with the oil sludge disposal and direct electricity generation or with oil condensing. Pyrolysis scheme with oil condensing may require further oil refinery.

Requirements to clean the contaminated sand and oil-water sludge after environmental catastrophes with oil tankers and rigs have led to the development of a special version of the pyrolysis system named as SOSA (Seawater-Oil-Sand). First SOSA plant was built in 1995.
