Fairly often during the exploitation of machinery (automobiles, motorcycles, chainsaws, motor cultivators, etc) there occur mini-spills, accidental oil spills (oil, gasoline, diesel fuel, kerosene) on soil and other surfaces, such as asphalt, concrete, stones etc.

Soils are the most difficult in recreation and remediation, as they accumulate toxic compounds that lead to decrease and cessation in plant growth. “Ultrachist” biopreparation can be used in situ, i.e. without removal of polluted soil that is actually for territories polluted with oil products: private homesteads as well as filling stations, automobile repair shops, car parks and garages, where it is difficult to carry out any other types of soil remediation.

During destruction of oil products there are not formed any harmful decay products, since biopreparation is composed from beneficial living microorganisms that naturally metabolize organic matter. These microorganisms notably accelerate the bioutilization of oil products and finally convert them to useful products that stimulate plant growth.
