Big Island Biodiesel piloting UH Hilo biogas system

In Hawaii, Big Island Biodiesel has teamed with the University of Hawaii at Hilo on a lab scale of an upflow anaerobic sludge blanket (UASB) reactor, a single tank wastewater treatment system. A pilot scale model of the UASB reactor is located in Keaʻau at Big Island Biodiesel, a branch of Pacific Biodiesel, a company that converts used cooking oil and grease into biodiesel fuel. If the pilot scale reactor proves to work in its intended environment, the full-scale model will allow the plant to convert its waste products into biogas, which will supplement the energy needs of the plant.
