Seabreeze Farm

Dairy manure RNG project in British Columbia


Seabreeze Farm has been growing their business with renewable energy since 2012. In 2021, the small dairy farm replaced their existing biogas upgrading system with DMT’s Carborex® MS. As one of five operational renewable natural gas (RNG) facilities in British Columbia (B.C.), Seabreeze Farm continues to be pioneers of producing RNG in Canada. This case study highlights the benefits of using DMT’s technology for dairy and agricultural projects.

  • Made locally in Canada
  • Replaced an existing biogas upgrading system
  • 99.5% methane recovery using 3-stage membranes


Year: 2021
Location: Delta, BC, Canada
Product: Carborex®MS
Biogas Inlet: 180 SCFM (290 Nm³/hr)
Biogas Source: Dairy Manure & Agricultural Waste
Application: Pipeline Injection

About the RNG Project in British Columbia

As pioneers of producing RNG in Canada, Seabreeze Farm, a small dairy farm in British Columbia, made headlines back in 2014 when they announced they combined anaerobic digestion with a water-wash system for biogas upgrading. The farm’s decision to recently replace their biogas upgrading equipment with DMT’s Carborex®MS reflects what analysts have witnessed over the last five years. Particularly that membrane separation is the prevalent technology used in North America’s RNG industry.

“We’ve been making manure and food waste a revenue generator since 2014. With our new DMT biogas upgrading system we look forward to making RNG more consistently.”

Jerry Keulen, Owner of Seabreeze Farm

The B.C. RNG facility upgrades 180 standard cubic feet per minute (SCFM), or 290 Nm3/hr, of biogas generated by 275 milk cows and 12,000 annual tons of off-farm organics. Using DMT’s three-stage membrane separation technology, biogas from an anaerobic digester undergoes conditioning and upgrading to become a purified RNG stream. This pipeline-spec RNG is then injected into Fortis BC’s utility pipeline to provide thermal energy for homes and businesses.

Project Results

In terms of GHG emissions, the project equates to removing 650 vehicles from roadways or generating energy for 360 homes. Currently, this facility is one of five operational RNG plants in B.C. with many under construction. With the Seabreeze Farm Facility operational, five percent of B.C.’s natural gas comes from renewable resources. According to a recent report by the Canadian Biogas Association, Canada has the capability to tap more than eight times its current biogas and RNG production.

“The RNG project with Seabreeze Farm and DMT is a prime example of Canada’s biogas potential. Biogas can help meet our national climate goals, meet provincial waste reduction targets, and deliver more low-carbon and energy. Canada needs biogas now more than ever.”
