Abstract

Present Master Thesis investigates the cumulative energy demand and greenhouse gas emissions of common waste management systems in Austria. The main task was to develop a dynamic Excel-based file that is capable of modelling the mass, energy and fossil carbon flows under different framework conditions. The determination of status quo in Austria was conducted for the separately collected recycling-fractions of metals, lightweight packaging/plastics, paper and cardboard, glass and biogenic waste. Residual waste is the mixed municipal solid waste fraction whose treatment is simulated as untreated landfilling, direct mono-incineration and different types of mechanical biological treatment followed by the co-incineration of high calorific fractions in cement plants. Furthermore, within the creation of this thesis data of an Austrian waste management association with a different collection system of only wet-residual waste, dry or recyclable waste, paper, glass and organic waste has been analysed. After determination of status quo for all systems, effects on cumulative energy demand and greenhouse gas emissions when meeting the EU-recycling targets are calculated. In different scenarios targets are met through a higher amount of separately collected waste and improved technology in sorting plants. Finally, the performance of the described waste collection and treatment strategies is compared and evaluated.
