This case study explores the production and use of renewable compressed natural gas (R-CNG)—derived from the anaerobic digestion (AD) of organic waste—to fuel heavy-duty refuse trucks and other natural gas vehicles in Sacramento, California. Like fossil compressed natural gas (CNG), waste-derived renewable CNG enables fleets to save on fuel costs, operate more quietly, and emit fewer greenhouse gases (GHG) and pollutants. In addition, by diverting organic waste from landfills and capturing the biogas that would have been emitted as the waste breaks down, production of R-CNG eliminates potent methane emissions that would otherwise escape into the atmosphere, achieving significant GHG reductions above and beyond fossil CNG.
