Abstract

This study presents a preliminary assessment of the implications on human health and ecosystem quality arising from increased materials and energy recovery from waste. Two scenarios were assessed encompassing different methods of waste distribution and elements of an integrated waste management system (composting, anaerobic digestion coupled with bio-methane recovery, incineration, and landfilling). The base scenario involved processing about 100,000 tonnes of municipal solid waste (MSW) per year and the modified scenario processed about 140,000 tonnes of MSW per year. The analysis was conducted following a life cycle approach using both midpoint and endpoint indicators. Based on a single tonne of waste processed, the results indicated lower (~ 66%) human toxicity with cancer and non-cancer effects (CTUh) and impact on human health (DALY) (~64% lower) for the modified scenario. Decrease in landfilling and increase in the recovery of the organic fraction from separated collection (OFSC) for biological treatment in the form of composting and anaerobic digestion in the modified scenario were the main drivers of these results. Considering savings in emissions from substituting the production of mineral fertilizers, the values of ecosystem quality (PDF*m2*year) indicated a lower impact (~86%) for the modified scenario.
