Abstract

This paper presents an assessment of potential environmental impacts for eight planned non-hazardous regional landfills in Macedonia. Waste quantities for each waste management region and landfill capacities are estimated. Expected leachate quantities are calculated using Water Balance Method. Analyses and comparison of the likely landfill leachate per capita are presented, demonstrating that higher rates of leachate are generated per capita in waste management regions with higher annual sums of rainfall. An assessment of the potential landfill impacts on the water environment taking into consideration local geology and hydrogeology conditions is presented. Some general measures for leachate treatment that are in compliance with the modern EU standards are indicated. The goal of the study is to facilitate a better understanding about the sustainable waste management practices in cases of landfilling of municipal solid waste.
