What we solve

Ex-situ cleaning of contaminated soils and sediments

In almost all civil engineering projects, contaminated soil is excavated in enormous quantities every day. Because of the widespread contamination that is almost everywhere, this soil is typically transported to earth-insulated landfills. For planning and regulatory reasons, however, landfill space is becoming increasingly scarce and expensive – and any ground intervention is therefore considerably expensive. In addition, the centralization of landfills has led to an increase in transport distances and thus also the environmental and traffic effects of traffic. There is an urgent need to find ecological and economic possibilities for sensible use of the excavated contaminated soil – as close as possible to the extraction point.

A self-contained environmental remediation and recycling process for contaminated soil material and its reuse is a reasonable option. By means of bioremediation by our microlive® bacterial consortia and the appropriately balanced ekocomplex® nutrients, toxic elements are released and toxic compounds are broken down into safe end products such as CO2, water and NH3.

The biological degradation of toxic compounds by microorganisms is already widespread worldwide. Compared to conventional methods (chemical, thermal, physical) this is much cheaper and can be used for larger quantities with simple application in-situ.

Our different bacterial consortia microlive® can extract a wide variety of heavy metals and use toxic compounds as food and break them down into safe end products. We have registered our technology as an EU patent on ecological release of elements and degradation of organic substances using heterotrophic microorganisms, confirmed on over 50 contaminated materials and in several bioremediation projects in the EU.
