Application of biodegradation for waste recovery

We produce the recultivation cover material through the so-named biodegradation process. Organic waste and non-organic waste are important components of the recultivation cover material. As a first step, any materials that cannot be used in the process (e.g. stone, metal waste) are sorted from the incoming waste and stored temporarily until they can be used another way, or forwarded to an authorised waste management company.

After sorting, we start to produce recultivation cover material based on the already known chemical composition and physical state of the waste. This is the so-called composite formation or homogenisation phase. In the mixer tank, we add to the main component the sewage sludge, some materials that help us to obtain the desired composition, namely to match the structure and porosity of our product with those of natural soil. To start biodegradation, an inoculating agent is added to the mixture at this stage. The biodegradation processes start to work at this very stage, even before placement in the so-called prisms. The maturing period is 6 to 12 months, depending on the raw materials used. Homogenisation is followed by a rest period, when the mixture, which has a high water content, is dewatered and dried. Biological processes are tested every 3 to 6 months.

The outcome of the maturing period is the recultivation cover material, which is suitable for utilisation on the sites right after the official inspection.


The processed waste becomes a natural component again after proper treatment and passing through controlled biological and chemical processes. The waste processed by us will decay to the same materials as those found in natural soils. Therefore, our product, which is subject to continuous official inspections, may be suitable for the improvement of agricultural soils.




“The technology used by Tata Environmental Co. is actually based on the 'copying' or modelling of natural processes. The well-defined mixture of different types of waste and inert substances resembles natural soil compositions. The different biodegradation and soil formation processes used are analogous to processes occurring in nature. As a result, the organic contaminants decompose and the added organic and inorganic components can be utilised. At the end of the decomposition and degradation process a composite material similar to natural soil is formed."
