Other digesters\u00a0produce methane, which is then burned to generate electricity.<\/p>\n<p style=\"text-align: justify;\">The company will use the fuel produced by its digester in its fleet of CNG-powered trucks.\u00a0\u201cWe\u2019re excited about the new digester because it allows us to turn compostable food scraps into fuel for the very trucks that collect those materials. It\u2019s a truly closed loop system,\u201d says company president Doug Button. \u201cPlus, the process keeps organic waste out of the landfill and cuts greenhouse gas emissions\u2014benefiting the communities we serve, the environment and our company.\u201d<\/p>\n<p style=\"text-align: justify;\">Made by <a href=\"http:\/\/www.zwes.ca\/Menu\/Home\">Zero Waste Energy, LLC,<\/a>\u00a0 the Blue Line Transfer anaerobic digester produces up to 500 diesel gallon equivalents (DGE) each day of carbon negative,\u00a0renewable CNG. \u00a0In addition, the process provides digestate, a nutrient-rich substance that will become certified organic compost. Compared to traditional composting, the dry anaerobic digestion process creates fewer greenhouse gas emissions and other air pollutants.<\/p>\n<p style=\"text-align: justify;\">SSFSC plans to process\u00a011,200 tons of food waste and food soiled paper every year from its customers in South San Francisco, Brisbane, Millbrae, Colma and the San Francisco International Airport. The new technology will serve an expanded push to sign up businesses for food scrap and food soiled paper collection.<\/p>\n<p style=\"text-align: justify;\">via <a
