A wide range of organic pollutants such as oil, petrol, creosote and phenols are used by natural microorganisms as sources of carbon and energy. The final products are gaseous carbon dioxide, water and biomass. The variety of natural microorganisms and their high reproduction rates enable them to quickly adapt to various pollutants and combinations thereof. They also produce the tensides needed to dissolve the substances in water themselves. The water content and the supply of oxygen and mineral nutrients are the main factors which are optimized in the technical exploitation of biological processes. This biotechnical treatment is preceded by the mechanical treatment of the contaminated material. Conditioning and homogenization enable the rapid, extensive degradation of pollutants. Biotechnical treatment is performed either in stationary treatment units, at the construction site, or in situ in the soil.

• Biologically degradable organic pollutants

• Soil, excavated material, building rubble
  
  
• Other waste
