Waste To Energy Technologies InUrban Setting: Comparative Analysis Of Environmental And Economic Performance

Abstract

This comprehensive study examines the environmental and economic performance of various waste-to-energy (WtE) technologies in urban settings. The research compares incineration, anaerobic digestion, gasification, and pyrolysis technologies, evaluating their efficiency, environmental impact, and economic viability. The study utilizes life cycle assessment (LCA) and cost-benefit analysis (CBA) methodologies to provide a holistic comparison. Results indicate that while incineration remains the most widely adopted WtE technology, anaerobic digestion shows promising environmental benefits, particularly in reducing greenhouse gas emissions. Gasification and pyrolysis demonstrate potential for higher energy recovery but face challenges in terms of technological maturity and economic feasibility. The study concludes that the optimal WtE technology choice depends on specific urban contexts, waste composition, and local energy demands, emphasizing the need for tailored solutions in urban waste management strategies.
