Zero Waste #Energy breaks ground on organic waste to CNG fuel facility

Zero Waste Energy, LLC (ZWE) broke ground on an anaerobic digestion facility in South San Francisco, CA that will convert organic waste into compressed natural gas (CNG) and compost. The Blue Line Biogenic CNG facility will convert 11,200 TPY of food and green waste into 100,000+ diesel equivalent gallons of CNG fuel. The company estimates that each collection vehicle will gather enough organic waste during just one route to fuel it for an entire day, creating a closed-loop system.

The facility is scheduled to commence operation in the second quarter of 2014.

The Blue Line Biogenic CNG Facility is being developed in a partnership with Blue Line Transfer Inc., South San Francisco Scavenger Co., Inc., and Zero Waste Energy, LLC.

The project addresses numerous AB 32 requirements, diverting almost 95% of the organic waste feedstock from landfills. The project will include a SMARTFERM anaerobic digestion facility with 8 dry digesters that will transform 11,200 tons of food and green waste per year into compressed natural gas (CNG), produce 60 kW of electric power and heat to run the facility, an in-vessel composting system that will mitigate odor issues and provide digestate that will be matured into compost.

SMARTFERM is an advanced dry anaerobic digestion system that processes organic waste feedstocks and generates renewable energy. SMARTFERM systems can include biogas-processing technology for combined heat and power (CHP) generation as well as compressed natural gas (CNG). In addition, in-vessel composting options can provide partial or complete maturing of compost for the wholesale or retail market. SMARTFERM facilities can process 4,000 TPY to 100,000 TPY of almost any organic material.
