AB - This paper presents the research findings of using two organic wastes – from feed additives production and malt production, which can optimize the process of soil remediation from petroleum products. The experiment was performed in situ with applying in the soil, contaminated with petroleum products (industrial oil), the excess sludge of malt production waste biological purification (1.8 or 3.6 kg/m2 was applied). The organic matter content in the sludge was 31.79 %. With account of the high initial concentration of petroleum products (3100−8600 mg/kg) and their degradation during a short-term experiment (21 days), a conclusion was made, that the excess sludge of wastewater biological treatment had the potential for remediating soils from petroleum products. The percent reduction made up from 16.12 to 85.64% (at applying 0.44 kg/m2 of petroleum products) and 20.37; 33.72 and 89.03 % (at applying 0.66 kg/m2 of petroleum products). From the second waste product, which contained 83.0 % of organic matter, − corn-steep extract purification sludge, − a water extract was obtained. It has been determined that the cell colonies, which appeared from this extract (8-fold dilution) in the agarized growth medium in the presence of used petroleum products, are not inhibited, and petroleum products become a source of biogenic carbon for them.
