The Washington Department of Commerce will provide $320,000 of Recovery Act funds to FPE Renewables, LLC to upgrade an existing anaerobic digester at Vander Haak Dairy in Lynden, Washington. This upgrade project will convert the digester from mesophillic operation to thermophillic operation. This conversion will require additional heat recovery capacity in a new generator set, a collection pit to provide a more consistent feedstock mixture, and some mechanical and utility upgrades to accommodate the additional heat and electricity. This project will allow FPE Renewables to produce more gas from the same amount of inputs. The project will utilize the excess biogas for which the current generator does not have capacity. The work will be conducted on Haak Dairy property on previously disturbed land.
