According to the companies, the Blue Line Biogenic CNG facility is the country’s first dry anaerobic digestion (AD) facility that converts biomethane into compressed natural gas (CNG) to fuel the collection vehicles that collected the organic material. This unique closed-loop system transforms 11,200 tons of food and green waste per year into biogenic compressed natural gas (CNG), produces heat to run the operations and provides high-quality compost. The facility can produce up to 120,000 diesel gallon equivalent (DGE) per year of carbon negative biogenic CNG—enough to fuel up to 18 of Blue Line sister company, South San Francisco Scavenger’s collection vehicles.
Each vehicle collects enough organic waste during just one route to fuel it for an entire day, creating a true closed-loop system and the first project of its kind in the United States. Based on current projections of the amount of fuel the dry-AD Facility produces for its CNG fleet, SSF Scavengers plans to achieve a 43 percent reduction in emissions from its entire fleet of vehicles..
