February 21 (Renewables Now) - US waste-to-energy developer Brightmark Energy LLC on Thursday said it has added two dairy farms, bringing the total number to six, to its Yellowjacket renewable natural gas (RNG) project in New York.
With the latest additions, the project will be able to capture methane from 265,000 gallons (1 million litres) of manure daily and convert it to RNG for heating or transport and other products. Gas upgrade equipment is expected to be installed across all farms by the beginning of 2021 and when this happens the project is forecast to produce about 305,000 MMBtu of RNG annually, making it the company's biggest RNG project to date.
The sites part of the project are: Boxler Dairy Farm and Swiss Valley Farms in Wyoming County; Lamb Lakeshore Dairy in Niagara County; Lamb Farms and Zuber Farms in Genesee County; and Lawnhurst in Ontario County. The RNG from the project is to be fed into the local interstate gas pipeline.
Brightmark is looking to partner with other dairy farms, waste water treatment plant operators and feedstock suppliers on biogas projects across the US.
