One of the largest environmental solutions providers in the USA aimed to reduce greenhouse gas emissions by employing renewable technologies. As part of its ongoing efforts, it sought assistance converting a landfill in California from a gas flaring operation to a landfill gas-to-energy facility. We managed the construction of this state-of-the-art plant. We started with bidding and subcontractor selection for landfill gas/HDPE piping, concrete, steel, carpentry, glazing, painting, fire protection, process piping, plumbing, heating, ventilation, and air-conditioning (HVAC), electrical, and high-voltage electrical scopes.
A pre-engineered metal building houses the gas treatment equipment and engines. An extensive controls system connects the equipment that compresses, cools, and filters the methane gas. The processed gas is piped to two reciprocating engines, which generate electricity around the clock. The state-of-the art emissions system includes scrubbers that remove carbon monoxide, sulfur oxide, and nitrogen oxide, making it one of the lowest emissions landfill gas-to-energy plants in the USA. The facility processes 1,100 SCFM of biogas, which is piped to the engines that produce 3.2 MW of renewable electricity 24 hours a day, seven days a week. This facility is capable of powering more than 5,000 homes.
