Green Methane as a Future Fuel for Light-Duty Vehicles

Food waste (FW) has traditionally been disposed by incineration or landfilling; however, it can be converted to green methane (GM) via anaerobic digestion, and GM used as fuel for light-duty natural gas vehicles (LDNGVs). A lifecycle assessment (LCA) of FW-based production LDNGV operation in China, a new scenario, was performed. The LCA results were compared with those the conventional FW treatment, where “well-to-wheel” system boundary including collection, from FW, vehicle manufacturing, operation, disposal defined. showed that global warming impacts scenario are 44.3% lower than option. fine particulate matter formation impact dominated displacement effect electricity supply followed CO2 adsorption primary source. sensitivity analysis hydroelectric power best source could substantially reduce both FRS scenario. In short term, proposed feasible option achieving sustainable society minimizing environmental treatment.
