Life Cycle Assessment of Anaerobic Digestion of Municipal Waste for Vehicle Biogas Production

Using ISO life cycle analysis and assessment methods, life cycle assessment (LCA) of anaerobic digestion of municipal waste for vehicle biogas production in Anyang was studied. Through the confirmation of the goal and scope, the inventory analysis and environment impact potential calculation were made to the vehicle biogas production process of anaerobic digestion of municipal waste. The results show that the maximum pollution emissions is in vehicle operation phase, and the maximum energy consumption is in vehicle biogas production phase, and the maximum contributions to environmental impact load is global warming, and the biogas generated by anaerobic digestion of municipal waste fully meets national standards for vehicle compressed natural gas. Finally According to life cycle inventory and environment impact assessment the analysis and suggestions were made to the city decision makers
