Step by step history of a digester near the Massachusetts/Connecticut border:

Step 1 – After meeting Dan Woodger (left) a few years ago, Jim Muir invited him to a presentation by a specialist from Pennsylvania (far right) about benefits of spreading liquid digestate on fields.


Step 2 – At the request of Rockwood Farm, Muir identified a project developer (right) to obtain food waste to co-digest with the farm’s manure. The drop-off or “tipping” fees from haulers make larger biogas facilities in southern New England financially viable.

Step 3 – In-ground digester tank by RCM Digesters under construction at Rockwood farm.

Step 4 – Dan Woodger in front of his digester which now co-digests the manure of 400 adult cows with liquid food waste. The structure being built to the right will house a “de-packager” to process more varied waste and provide higher tipping fees to the farm.

Meeting of southern New England farmers we organized that included the Connecticut EPA, a generator set provider and representatives of five interested dairy farms. We heard from Jedd Moncavage of TeamAG (far right), who traveled from Lancaster County, PA  to share his experience with digested manure solids at the ten dairy farms he services (here is a video link with more on this subject). Today, three of these farms have operating digesters, another has a digester under development, and the fifth will truck his manure to one of these projects for digesting.
