The fourth largest landfill site in the United States will get a renewable energy project.PORTLAND, Oregon , US, 2001-08-01 [SolarAccess.com] The fourth largest landfill site in the United States will get a renewable energy project. The Roosevelt Regional Landfill in Washington state will use a separation process to clean and remove carbon dioxide from the landfill gas. In a process developed by Acrion Technologies and provided by Evergreen Eco-Resources, gas from the landfill will fuel an electricity generator and the captured CO2 will be sold commercially. The initiative is the first renewable energy project undertaken by the Climate Trust Board in Oregon. “We’re excited to fund the first commercial-scale demonstration of this innovative environmental technology,” says CTB chair Diana Bodtker. “This technology should provide landfill operators with an important tool for countering global warming pollution while enhancing their revenues with carbon dioxide sales.” The CO2 separator is the product of a decade of research and development jointly funded by the U. S. Department of Energy and the private sector. The electrical generation will displace the need to burn fossil fuels at other power plants in the region. “Since burning fossil fuels releases carbon dioxide, the atmosphere’s bottom line will be improved,” adds executive director Mike Burnett. The captured CO2 will be sold to nurseries that currently stimulate plant growth in greenhouses by burning propane to increase carbon dioxide levels. Displacing the burning of propane provides a second source of CO2 offsets from the project. The separator will also eliminate nearly all major air pollutants from the landfill gas, including volatile organic compounds such as HFCs, PFCs, SF6 and other potent greenhouse gases, as well as sulfur compounds such as sulfur dioxide that causes acid rain. CTB was formed in 1997 in response to Oregon legislation that limits the amount of CO2 that a new power plant can emit. Facilities can comply with the standard by paying the Trust, which uses the money to fund projects that reduce atmospheric CO2 levels. Initial funding for the CTB came from the 480 MW Klamath cogeneration project that is nearing construction in Oregon. Four other projects involve financing of wind power facilities in the state.
