Assessment of the Impact of Municipal Solid Waste Landfills on the Environment of the Krasnodar Region

Abstract

The goal is to assess the impact of municipal solid waste landfi lls on the environment of the Krasnodar Region to further determine effi cient waste management technologies within the framework of forming a regional closed-cycle economy model. Materials and methods. The following research methods were used: information analysis, retrospective analysis, assessment of the current state of scientifi c developments and the application of innovative technologies, methods for analyzing the chemical and morphological composition of municipal solid waste, methods for calculating gas emissions, synthesis, and observation. Results and discussion. The main pollutants emitted into the region's atmosphere, as well as the share of greenhouse gas emissions by sectors of the region's economy, have been identifi ed. The average morphological composition of mu nicipal solid waste and the component composition of biogas at the accumulation landfi lls were determined. The average content of petroleum products and the average gross concentration of heavy metals in the soil of the landfi lls were revealed. The eff ect of landfi ll soil compaction on the effi ciency of aerobic and anaerobic processes in the landfi ll body was revealed. Methane emissions were calculated for various morphological compositions of municipal solid waste. Conclusion. The use of an integrated approach based on the introduction of the best available technologies allows for a signifi cant reduction in the negative impact of municipal solid wastes landfi lls on the environment of the Krasnodar Region, which largely contributes to the formation of a closed-cycle regional economy model in the region.
