After reducing the amount of emitted biogas to the safe level, biological products are introduced into
the wells for binding toxic substances into inert compounds, effectively destroying residual organic
matter and pathogenic microflora. These biological products are successfully used in industrial
wastewater treatment plants for the treatment of highly polluted wastewater and its degassing to the
state of technical water with the possibility of its discharge into fish-breeding reservoirs. The
biological products sink into the ground through the body of the landfill, neutralize the accumulated
toxic substances and pathogenic microflora, degas the soil being spread by groundwater, which
contributes to the rapid recovery of fertile ground and underlying soils, without employing expensive
and ineffective mechanical or chemical recultivation.
