Waste management

ERMONASSA SA takes part in a collective system for the alternative management of construction and demolition waste and has the expertise to organize similar projects around the world. Construction and demolition (C&D) waste represent a special challenge, since it is produced in very large quantities and without proper management it can seriously affect the environment.


We also offer waste management services for sorted waste, such as waste paper (recycling mills), plastics (production of granulates), waste of electrical and electronic equipment or WEEE (recycling plants). Finally, ERMONASSA SA can offer solutions for the management of hazardous waste (contact the company for more information).

Wastewater Treatment Plant

Wastewater from households and industrial sources can be treated and be either safely disposed or reused for various applications. The size and the processing line of the wastewater treatment plant depend on the quality of the incoming wastewater and on the desired use. Our company undertakes the planning and construction of wastewater treatment plants for household and/or industrial sources.


Household wastewater treatment in the EU requires the use of primary and secondary treatment methods. Further treatment depends on the desired use of the processed wastewater. The processed water may be reused for irrigation or for industrial use.


Primary and secondary treatment methods are included. Moreover, the sludge can be treated and to be turned into suitable material for landfill cover. Please contact us for more information on further treatment.

Remediation of hydrocarbon contaminants

This case study concerns the construction, transportation and operation of a plant for the recovery of pollution from hydrocarbons. The plant was designed so as to be able to process waste by different levels of pollution. The goal was the recovery of hydrocarbons from the soil and sand. For easy relocation of the entire unit from region to region, the unit was manufactured as semi-mobile. Following each restoration project, the unit was transferred to a new location without the requirement for new buildings or supply facilities.


Performance data

Heating system: Thermal oil with temperature up to 400 °C.

Fuel: Diesel.

Unit type: Semi-mobile unit.

Batch size: 7 m3.

Throughput capacity: 2 – 5 t/h depending on level of pollution.

MBT plant for household waste

Household waste contains a lot of valuable materials, such as metals and plastics, as well as organic material that can be converted into either energy or compost. There is a wide selection of proven methodologies and technologies to be used for Household waste management.


Our company undertakes the planning and construction of Mechanical and Biological Treatment (MBT) plants for the management of Household waste. The first step of the planning is the analysis of the waste to be processed, which can vary even within the same town or municipality (between similar areas).


Quantitative and qualitative factors of the waste determine the selection of the applied technologies (i.e. if there is a high percentage of plastics and textiles, then focus on RDF production).


Our people have experience is some of the largest plants in Europe, including the one in Ano Liosia in Greece  (pictured), which has three processing lines and can handle up to 1.200 t/day.

Contaminated soil

The combination of heat with vacuum under completely controlled conditions achieves the separation of the pollutants and/or useable resources from the processed material. The treatment is accomplished by physical means – without burning the chemicals. This method ensures the proper processing whilst reducing the produced pollutants to a minimum, so it can be installed next to other facilities and in close proximity to residential areas.



Oily waste (refinery waste, drilling cuttings, oil sludge etc).

Mercury waste (catalysts, filter cakes, sludge, residues etc).

Contaminated soil (hydrocarbons, PCB, dioxins, mercury, solvents, organic lead etc).

Grinding swarfs and mill scale from metal processing.


Key facts

Heating system: Thermal oil with temperature up to 400 °C.

Energy source: Fuel oil, diesel, natural gas, biofuels, electricity.

Evaporation range: Boiling point up to 450 °C is achieved under vacuum.

Plant design: Fixed or mobile unit from 0.5 to 10 t/h.

Additional resources: Electricity, nitrogen, compressed air, water.


Advantages of the technology

Efficient heat transfer for drying process (efficiency > 80%).

Emission and dust free system via enclosed treatment of exhaust vapours and solids.

ATEX certified technology.

Design standards according to EN, ASME, GOST-R.

24/7 operation with 7,000 h/y guarantee.

Recycling Plants

Recycling waste is an old practice that has found a lot of applications in the 21st century. A lot of the produced wastes contain valuable materials that can be recovered and sold for a profit. Our company undertakes the planning and construction of recycling plants for waste of electrical and electronic equipment (WEEE), lead (Pb) accumulators and end of life vehicles (ELV). EU legislation requires all interested parties (producers, importers etc) to finance recycling facilities for the alternative management of the waste.


Waste of electrical and electronic equipment contain computers, refrigerators, TVs, washing machines, toys etc. WEEE contains a lot of different metals, as well as precious metals, that can be separated through either mechanically or by hand. Some contain dangerous materials that must be managed as such. WEEE recycling is a profitable business when properly organised.


Lead (Pb) accumulators are used in a lot of different applications and every year large quantities have to be properly managed. Lead (Pb) is of high value and therefore recycling of lead accumulators is a very profitable business. There are a few different options for the processing line that have different efficiencies and end-products. Choosing the best solution is based on a market analysis that takes the existing local legislation into consideration.


End of life vehicles are considered to be one of the most interesting sectors of waste recycling. ELV’s are composed mainly of old passenger cars, but new ones are coming into the mix with increasing rates. The differences between old and new vehicles are a lot, but they are processed in the same line. Most of the parts of a vehicle are made from metals and plastics. The methodology of vehicle recycling is not complicated, but the depollution (removal of dangerous materials) is mandatory prior to processing. Our people are experienced in planning, licensing and constructing recycling plants in Europe.
