DariTech – Tillamook

The plant, situated within the foundation of a former World War II blimp hangar, willprocess manure from the equivalent of 5,000 milking Holsteins from Tillamookcommunity dairies. Manure will be delivered in tanker trucks, and treated effluent will bereturned to the dairies for agricultural applications. No substrates will be digested withthe manure. The new system has three 1-million gallon insulated tanks — two fordigestion and a third for “finishing” the effluent. There are also two 250,000-gallonstorage tanks, one for receiving manure and the other for off-load back to the farms thatare bringing manure to POTB. This modern biogas plant will provide electricity to theTillamook People’s Utility District. POTB plans to sell the fiber by-product to nurseries andother horticultural users across the Pacific Northwest and northern California.
