Abstract The aim of this study is to quantify the environmental exchanges associated with the mechanical–biological treatment (MBT) of mixed municipal waste, for a specific MBT plant, based on the annual operation data for the year 2015. Modeling of environmental performance of the MBT technology is done on actual, real data of the operating plant, taking into account particular, explicit outputs and efficiencies of the plant. Results contribute to quantitative understanding of MBT technology and its environmental impact, including the impacts from individual unit processes within MBT. The study is based on Life Cycle Assessment methodology, employing the EASETECH model. One megagram of mixed municipal waste entering the MBT plant is adopted as the functional unit. The system boundaries cover the whole value chain from collection and transport of mixed municipal waste through mechanical and biological operations until final treatment of end-waste generated in the MBT plant. Results of modeling show the MB...
