Manure, digester effluent (inoculum), and four food processing waste influents that are received weekly (or bi-weekly) at the Kilby Dairy Farm in Rising Sun, MD and placed into a covered lagoon dairy manure digester were collected. The digester input consists of 98% (by volume) cow manure and the remaining 2% consists of wastes from separate off-site manufacturing of cranberry sauce (CS), chicken fat for marinades (CK), meatball fat from frozen food processing (MB), and an on-site ice-cream processing plant (IC). The cow manure and the IC wastes are directed to the covered lagoon digester daily, with the CK wastes trucked to the farm and added weekly, and the cranberry and meatball wastes added on alternating weeks. Samples of the food wastes from the four food production processes were collected at the farm before being added to the digester, brought to the laboratory on ice and tested.
