Brightmark partners with New York dairy farms to produce RNG from manure

In the United States (US), Brightmark LLC (Brightmark), a San Francisco, California (CA) based waste-to-energy development company, has recently announced that it has partnered with three New York dairy farms on the Helios Project, the latest in a series of renewable natural gas (RNG) projects the company has launched over the past two years.

Gardeau Crest Farms located in Perry, Western New York, and Lawnhurst Farms in Stanley, and Willet Dairy in King Ferry, in New York’s Finger Lakes Region, have each signed supply agreements with Brightmark indicating their intent to provide the company with dairy manure from their herds that will serve as feedstock for the three existing anaerobic digesters on the farms.

The digesters will capture and extract the biogas in the manure, then upgrade it to pipeline quality biomethane (aka renewable natural gas – RNG) and inject it into a nearby gas pipeline for distribution.

Part of Chevron JV

The project is part of the recently announced joint venture Brightmark RNG Holdings LLC, a Brightmark platform in partnership with Chevron U.S.A. Inc. Once all of these projects are operational, Brightmark’s RNG projects will generate enough RNG each year to drive 1 600 18-wheeler trucks from San Francisco to New York City.

When fully operational in the third quarter of 2021, the digesters will produce up to 500 MMBtu of RNG per day or 182 500 MMBtu per year between the three dairy farms. Brightmark has partnered on RNG projects with 23 dairy farms in nine states over the past two years.

We are excited to partner with Gardeau Crest, Lawnhurst, and Willet to further expand our renewable natural gas projects in New York and deliver environmental and economic benefits to their communities. Brightmark aims to offset 22 million tonnes of CO2 by 2024 with our RNG projects and these partnerships are critical in helping us achieve our goal, said Bob Powell, Founder, and CEO of Brightmark

RNG a beneficial manure treatment option

Anaerobic digestion (AD) systems can prevent significant quantities of methane, a potent greenhouse gas (GHG), from being released into the atmosphere. According to Brightmark, research shows that when all climate benefits are considered together, RNG from dairy manure can reduce GHG emissions 400 percent when it is used to replace traditional vehicle fuels through this net carbon-negative process.

These projects will reduce the net GHG emissions from the manure processed at this facility at a rate of 55 000 tonnes of CO2e annually. After the methane is extracted from the processed manure, the remaining materials will be returned to the farmers for use as fertilizer on their fields that grow crops for their cows.

These partnerships will allow the farms to reduce land application of manure and improve odor and nutrient management practices.

We are proud to partner with Brightmark to further reduce our environmental impact and to ensure that we continue to be good neighbors to our local community with the odor management benefits our anaerobic digester provides. This partnership allows us to convert our manure waste into a valuable resource, while also improving odor control and reducing our emissions – a win-win-win for our farm, our community, and the environment, said Don Jensen of Lawnhurst Farms.
