El Sobrante Landfill recently invested nearly $500,000 to expand its landfill gas collection system. Twenty-one gas collection wells were added to an already existing system of 160 gas collection wells that are located throughout the landfill.
The additional gas collection wells will improve the extraction of methane gas, which is produced by the natural decomposition of waste. The high-quality methane is sent to a gas-to-energy facility that converts it into nearly four megawatts of electricity while the lower quality gas is sent to El Sobrante?s state-of-the-art ultra-low emissions gas flare.
On a national level, Waste Management recently pledged to double its renewable energy output to ultimately power more than 2 million homes by 2020. Currently WM provides enough fuel to power a million homes through its gas-to-energy stations. That?s the equivalent of replacing 14 million barrels of oil or 3.6 million tons of coal every year.
