Landfill Gas-to-Energy Construction Management

One of the largest environmental solutions providers in the U.S. sought to improve the profitability of its landfills, while concurrently decreasing greenhouse gas emissions. Our construction team converted this landfill to an energy-generating system to help achieve that goal. Gas treatment includes a 10,000-gallon knockout pot to remove condensate, compressors, aftercoolers, radiators, and silencers. The plant is equipped with three 20-cylinder, 2,233-HP engines. Electrical work included installation of 3.5 miles of high-voltage lines, work at three substations, and laying of fiber optic, water, and force main to connect to the SVC building. New switchgear and master control center tie all the equipment together. When faced with unexpected site conditions such as an underground drain tile system, our constructors quickly pivoted to maintain the project’s critical path. This landfill gas-to-energy system treats 1,650 SCFM of gas emitted from decomposing organics in the landfill and generates 4.8 MW of electricity, an amount capable of powering over 4,000 homes.
