GHG Emissions in the Current and Future MSW Management System in Zvornik, Bosnia and Herzegovina

Abstract

Each and every step in the process of municipal solid waste (MSW) management generates the greenhouse gases (GHG). Therefore, it is imperative to focus on MSW from the source to the final waste disposal in order to decrease the negative impact on the environment. This study aims to calculate the GHG emissions at the present moment (Status Quo) for waste management as well as on the improved MSW management that should be implemented in this local community by 2027 (Scenario 2027). To visualize waste streams in these two scenarios, the STAN 2.5 software was used, and for the calculation of GHG emissions in the City of Zvornik, the IWM-2 software was used. The MSW management Status Quo is basically characterized by the collection communal of waste and its deposition on the landfill without a degasification system and landfill gas treatment. The guidelines and recommendations for MSW management improvement, Scenario 2027 propose the establishment of separate collections of secondary raw materials and biodegradable waste, and improved collection and treatment of landfill gas at the landfill site. The implementation of these measures would result in a reduction of approximately 40% in GHG emissions compared to the Status Quo. The most significant impact would be realized in the environment due to the collection and treatment of landfill.
