Using life cycle assessment (LCA) to evaluate environmental impacts of biogas distributed generation systems from municipal solid waste in buildings

Abstract

This paper accesses the environmental impacts over the entire life cycle of biogas distributed system using a traditional life cycle assessment (LCA) methodology. The result shows that biogas distributed system from municipal food waste could reduce vulnerabilities, and cut greenhouse gas emissions in a considerable amount in buildings. The result also establishes a network of process to examine a large number of paths to identify not only the phase emit the most environmentally damaging systems but the promising process for improvement of biogas system design.
