1. BTC PTEC Biodiesel Workshop August 7 – 8, 2006 BTC Pilot unit

2. BTC Biodiesel Pilot Plant The Northwest Energy Technology Collaborative (NWETC), a division of the Washington Technology Center (WTC), was awarded a $70,000 grant from the U.S. Environmental Protection Agency to conduct a one year demonstration project of a process that will provide fuel that will reduce diesel emissions. Matching funds of $280,000 were also raised to support this effort. NWETC procured four bio-diesel processors from BioDiesel Works. Two of these processors were installed at each of the participating colleges – Bellingham Technical College and British Columbia Institute of Technology. Student employees were trained to produce the bio- diesel as part of the colleges’ educational curricula.

3. BTC Biodiesel Pilot Plant The small biodiesel production units are converting filtered fryer oil from restaurants and food production into a cleaner bio-diesel fuel for commercial utility vehicles. The units will produce 144,000 gallons of bio-diesel fuel for the first year of operation. Puget Sound Energy (Washington) and BC Hydro (British Columbia) will operate utility trucks on the hybrid bio-diesel fuels. Each company will run a fleet of trucks that uses one of three blends of the bio-diesel product: B-5 (5 percent bio-diesel), B-20 (20 percent bio-diesel) or B-100 (100 percent bio-diesel). Total bio-diesel usage will be 12,000 gallons per month. The utilities will purchase the bio-diesel at the traditional diesel fuel price.
