The use of waste as a secondary raw material is an environmental priority

In order to produce a cover layer we need good quality raw materials, that is, waste, which can be used for making a product that has characteristics similar to those of natural soil.

The processed waste consists of organic and inorganic components. The organic materials decompose during biodegradation, while inorganic materials form the frame structure of the cover material to be prepared. Any waste component that cannot be recycled by our technology (e.g. sorted out waste, packaging material, etc.) is forwarded to authorised waste management companies.

Authorised waste includes around 50 materials that are classified under different codes by the relevant regulations according to their origin.

The main waste categories that we use are the following:

          waste with oil content, e.g. oil-contaminated soil, oily sludge from car-wash companies;

          waste with high organic matter content, e.g. waste water sludge;

          easily degradable organic waste, e.g. biowaste, green waste or food industry waste;

          mineral or inorganic waste, e.g. fly ash, flue-gas cleaning waste, rock-dust, lime sludge;

          other substances, e.g. rain- or condensate water.

During the special process, processes similar to those in nature take place, but much more quickly, under controlled conditions and at an industrial scale.

The cover material produced can only be used after certification, with an individual license, subject to an adequate regulatory control.



“Inorganic waste (slag, dust-ash, etc.) accepted for use in our technology replaces the mineral components present in natural soil processes and plays the same role.

“Some microorganisms are able to use hydrocarbons—which are toxic to other living beings or difficult to degrade—as carbon sources for their vital functions. Of course, these microorganisms also need other macro-, meso- and micronutrients to build their body structure, grow and reproduce. It is more reasonable if the microbes get access to these essential substances by using the inorganic components of the pollution carrier medium (soil, waste).”

“The time needed for degradation may vary within wide limits—i.e. from a few weeks to several months or years—depending on the degree and nature of contamination and other factors influencing the vital functions and reproduction of microorganisms. Therefore, the efficiency of the inoculating agent not only depends on the manufacturer, but to a significant degree also on the professional work carried out by the staff in charge of the particular operation.”
