Croton Landfill, a 125 acre inactive Class II hazardous waste landfill, was capped in March 1995 and included the installation of 110 gas extraction wells and a gas collection system. With an estimated initial Landfill Gas flow of 1.4 million cubic feet per day and a methane content of about 50%, the landfill gas is a valuable energy source. Westchester County decided to utilize this methane gas.

Savin performed the design and construction management of this project, including an electrical power generation facility and a pilot-scale compressed natural gas (CNG) facility. The electricity produced from the gas-to-electricity facility will meet the needs of the landfill and adjacent Croton Park facilities.

The CNG pilot facility utilized innovative technology to purify the landfill gas to pipeline quality natural gas, which can then be sold to gas utilities or used as a fuel to operate CNG vehicles. The CNG pilot facility processed approximately 100,000 cubic feet per day and operated for two years.
