BioFuels Washington, LLC

Landfill Gas to Energy Facility

Tacoma-Pierce County Health Department originally issued a solid waste permit for the BioFuels Washington, LLC Landfill Gas to Energy Facility located at the LRI Landfill on December 14, 2012. That permit was most recently renewed on December 11, 2014.

Construction of the Biofuels facility began in the spring of 2013 and continued through the summer and fall. The facility began start-up activities in November 2013 and began producing electricity in December 2013. The facility is currently in full commercial operation and generates up to 4.5 megawatts of electricity.

The BioFuels facility uses landfill gas generated at the LRI Landfill to generate electricity and may in the future produce compressed natural gas (CNG). The renewable energy facility is located at the northern end of the LRI Landfill adjacent to the landfill gas flares. Landfill gas is piped to the facility where it is combusted in large Caterpillar engines. These engines power generators that create the renewable energy (electricity). The electricity is sold to and fed into the regional Puget Sound Energy electrical grid.

BioFuels originally proposed to develop the site in three phases. The first phase of facility development was Phase 1A, the conversion of landfill gas to electricity (now complete), followed by Phase 1B, the conversion of landfill gas to CNG. Proceeding with the production of CNG is currently on hold due to changing economic conditions. BioFuels may choose not to proceed with the production of CNG at the facility as originally planned. If CNG production is not economically advantageous, BioFuels will likely proceed with the development of additional electrical generation capacity at the site.
