The ecological reconstruction of the sites contaminated with petroleum products is necessary to restore the geological environments affected by the economic activities specific to the petroleum industry. The purpose of ecological reconstruction is for the site to be returned to the environment for the resumption of economic and landscape functions, without presenting risks to the environment and human health. Decontamination technologies are based on various bioremediation methods. In many cases, significant amounts of soil are required to fill the resulting excavations and to systematize the land to complete the ecological reconstruction work. In the present study, the possibility to use sludge collected from a municipal wastewater treatment plant in the ecological reconstruction is presented. Both, the presence of hydrocarbon-degrading bacteria and the geotechnical characteristics make it possible to use the waste dehydrated sludge for the ecological reconstruction of the sites contaminated with petroleum products.
