Patterson Farms (credit:

Patterson Farms, Inc. is a 6th generation farm, which was founded in 1830. In 1999 the family installed a composting facility for composting solids (even prior to subsequently adding a digester in 2005). Because they had been spreading manure in summertime (since it is environmentally the best thing to do), the odor elicited complaints from neighbors, which prompted them to look into anaerobic digestion as a possible solution. Six years later, the complete mix digester was up and running. Currently, the digester processes 45,000 gallons per day of raw manure pre-mixed with 15,000 – 22,000 gallons per day of whey.
