Brightmark Energy to expand western New York dairy biogas project

In the United States (US), Brightmark Energy LLC (Brightmark), a San Francisco, California (CA) based waste-to-energy development company, has announced that it has expanded its Western New York dairy biogas project to partner with six total farms throughout the region. Including two new farms, the Yellowjacket project will extract methane from 265 000 (US) gallons (≈ 1 million litres) of dairy manure per day and convert it into renewable natural gas (RNG) and other useful products.

According to a statement, the six farms participating in the Yellowjacket renewable natural gas (RNG) project include:

  • Boxler Dairy Farm – Varysburg, Wyoming County
  • Lamb Lakeshore Dairy – Wilson, Niagara County
  • Lamb Farms – Oakfield, Genesee County
  • Lawnhurst Farms – Stanley, Ontario County
  • Swiss Valley Farms – Warsaw, Wyoming County
  • Zuber Farms – Byron, Genesee County

After the planned installation of gas upgrade equipment across all of the farms is complete in early 2021, the project is anticipated to produce about 305 000 MMBtu of renewable natural gas each year, making this Brightmark’s largest RNG project to date. The company has partnered on biogas projects with 17 dairy farms in five states over the past two years.

We’re excited to expand our footprint in Western New York through the expansion of the Yellowjacket RNG project. We’re proud to partner with farmers who are on the leading edge of sustainability so that they can improve their bottom lines while being good stewards of their local environment, said Bob Powell, CEO of Brightmark Energy.

Refurbish and upgrade existing digesters

Previously, the anaerobic digesters on these farms produced electricity that was used both on-site by the farms and transmitted to the local electric grid. However, some of the digesters are more than 10 years old, and they had begun to cost more to maintain and operate than they generated in value.

Brightmark’s investments will include upgrading each digester to new technology capable of cleaning the methane gas and converting it into high-quality RNG for use in heating or transportation. The gas is expected to be injected into a local interstate gas pipeline.

After refurbishment work is completed on the systems, participating farmers expect to see drastically greater returns on their digesters, while further minimizing the local environmental impacts of the manure generated by their herds.

We’re really committed to protecting the environment and doing what’s best for the local community. We are excited to have the opportunity to partner with Brightmark to convert from generating electricity to producing RNG. This process will greatly reduce operational costs and with this technology increase the return on our investment, said Don Jensen, owner of Lawnhurst Farms.

Reduce GHG emissions and increase nutrient recycling

According to Brightmark, anaerobic digestion (AD) of dairy cow manure has been shown to significantly reduce local pollution and greenhouse gas (GHG) emissions. The process retains most of the nitrogen and phosphorus from manure and uses these nutrients to create balanced biofertilizers that help grow local crops.

Anaerobic digestion systems can prevent significant quantities of methane, a potent GHG, from being released into the atmosphere. This project will reduce the net GHG emissions from the manure processed at this facility at a rate of 117 783 tonnes per annum.

The New York State Energy Research and Development Authority (NYSERDA) is providing initial project planning funding and projects may be eligible for additional funding to implement upgrades to the digesters.

Brightmark is actively seeking other dairy farmers, wastewater treatment plant (WWTP) operators, and feedstock suppliers with an interest in collaborating on biogas projects throughout the United States.
