Investigating the mitigation of greenhouse gas emissions from municipal solid waste management using ant colony algorithm, Monte Carlo simulation and LCA approach in terms of EU Green Deal

•This study majorly aimed to determine the effect of optimization on transport routes on the reduction of greenhouse gas (GHG) emissions from municipal solid waste management (MSM) within the scope of European Union (EU) Green Deal.•Apart from the previous studies, although several studies focused on economic dimension of optimization, this study has concentrated on the environmental issues in terms of GHG emissions.•The reduction values related to GHG emissions have been overlapped with each other in the result of route optimization with used methodologies which are ACA, Monte Carlo simulation and LCA in terms of GWP.
