RICHLAND, Wash. – The City of Richland is commemorating the grand opening of the Horn Rapids Landfill Renewable Natural Gas (RNG) Facility, according to a news release.
The news release says the City and Pine Creek RNG entered an agreement in 2017 to create a new landfill gas treatment system to turn the methane gas at the City’s landfill into renewable natural gas.
Construction projects at the Horn Rapids Landfill and a Lamb Weston potato processing plant is now complete. The two would produce 2.5 million therms of renewable natural gas annually.
RNG is produced by capturing methane that would otherwise get into the atmosphere through landfills, wastewater treatment plants and food waste and purifying it to be used in homes.
Before the facility’s construction, the City used a flare to destroy methane produced by the landfill. That process will no longer be in use.
Pine Creek RNG from Denver collaborated with Avista in Spokane to build both treatment systems.
