Farm Digester Evolution In Vermont
Maplehurst Farm in Greensboro installed a 300,000-gallon RCM digester to process manure from about 375 dairy cows. Recently, it was approved to receive off-farm feedstock to boost biogas production.

With over 15 operating anaerobic digesters and several innovative power purchase incentive programs, Vermont provides an opportunity to assess what is required
to advance AD in the agricultural sector.
