I. Introduction
Municipal solid waste management requires a partial analysis of many aspects to establish a system with sustainable development. Many mathematical models have been made that represent a different way in which the collection, selection, transport, and storage of municipal solid waste is designed [1], [2]. The developed plan for the Pelagonija region foresees the reduction of organic biodegradable waste that is taken to the landfill, and it is directed to processes of recycling, composting, etc. However, a significant part of the biodegradable waste will end up in the landfill where biogas will be produced through anaerobic digestion over time. This enables an installation of energy systems for utilizing the components of biogas (methane), as well as preventing negative impacts on the environment (release of carbon dioxide and NMOC - nonmethane organic compounds). Therefore, a mathematical model and simulation for the production of biogas in the planned landfill is made using LandGEM [3], based and adapted according to the projected analyzes for the quality, quantity and composition of the municipal solid waste in the Pelagonija region. The Landfill Gas Emissions Model (LandGEM, version 3.03) tool is available for free use.
