The Vanguard Renewables anaerobic digester, located on the Goodrich Farm in Salisbury, Vermont, is a state-of-the-art facility that receives up to 180 tons/day food waste and 100 tons/day cow manure and transforms these waste products into animal bedding, renewable natural gas, heat, and a liquid fertilizer. The facility is off-the-grid and generates its own electricity. The renewable natural gas produced by the twin digesters is upgraded to gas pipeline standards and injected into the Vermont Gas Systems pipeline. The liquid fertilizer exiting the digesters goes through a phosphorous removal process to reduce the impact on surrounding waterways and Lake Champlain. The combination and integration of these processes makes this award-winning facility an industry model for the future. The project was awarded the 2019 American Biogas Council's Up-and-Coming Project of the Year, and in 2021 enabled Goodrich Farm to receive the 2021 US Dairy Award for Outstanding Dairy Farm Sustainability. The project's grand opening was held in August 2021.
