Digester Developer Finds Sweet Spots
Vanguard Renewables uses an “everybody wins” approach as it builds, owns and operates anaerobic digesters on dairy farms to process food waste and manure according to a recent article by Nora Goldstein in BioCycle Magazine.

Vanguard Renewables was recently named 2018 Organics Recycler of the Year by the National Waste & Recycling Association recognizing the substantial contribution that Vanguard’s Farm Powered organics recycling and renewable energy production program is making to protect the environment and advance the waste and recycling industry.
With its recently opened fifth farm digester in Haverhill, Massachusetts, Vanguard has capacity to manage 490 tons/day of food waste and 120 tons/day of dairy manure.
Having multiple digesters in central and western Massachusetts gives Vanguard Renewables the insurance that if one digester is down, it has other facilities that can receive the food waste. “Having backup is super critical,” says Hanselman. “If we didn’t have redundancy in our processing capacity, the generator gets stuck with having to find an alternative outlet. Our goal from the outset was to beat that. We always have enough AD capacity.”
