The promise of renewable natural gas is a sustainability win that has been financially and logistically out of reach for even the largest companies. Vanguard Renewables created the Farm Powered Strategic Alliance to start delivering on this promise for its founding members Unilever, Starbucks and Dairy Farmers of America.
The Massachusetts-based recycler uses anaerobic biodigesters to create renewable natural gas from food waste. Bacteria in the digesters consume the waste, creating methane and CO2 as byproducts. The gas can then be used for energy purposes.
