Abstract

In the period from 2013 to 2020, in all regions of Russia, there was an increase in household waste by 4.5-6.9 times an average. The study has identified that the properties of some wastes allow using them in economic sphere; it predetermines the interest in wastes as a secondary material resource. Some waste can be used as a fertilizer material and a substance for soil formation. It has to be considered that waste use can cause a number of serious negative processes, affecting all components of the ecosystem. Moreover, the polluting strength depends on the chemical composition of waste and the regulations for waste use. The purpose of the study is a geoecologic assessment of the resource potential of household waste in Orel in order to determine the possibility of their subsequent use in the region’s agriculture. The authors have presented the results of a ten-year monitoring of the resource potential of sewage sludge. According to chemical and biological components determined by the analyses, the examined waste belongs to IV, V classes of danger to the environment. It proves that they can serve as an organomineral fertilizer for the biological reclamation of disturbed lands.
