The Challenge

Millions of tons of organic waste are produced daily—releasing methane and other harmful gasses, wasting energy potential, and creating disposal costs for industries and municipalities. Meanwhile, tightening emissions and solid-waste disposal regulations are forcing companies to find sustainable solutions fast.

The Opportunity

C2 Biogas turns environmental regulatory requirements into economic opportunity—providing a path to compliance that generates revenue instead of costs by transforming waste into RNG.

It’s not just what we do,
it’s how we do it.

Utility-Scale Energy Infrastructure

C2 Biogas’s plant is one of the largest biogas facilities in North America: an in-house designed, 100-foot high industrial complex producing pipeline-quality RNG, which can reliably power the equivalent of tens of thousands of homes.

Smart Use of Organic Resources

We capture value from residual organic byproducts, including pre-consumer food processing material and agricultural inputs, transforming them into clean energy. This diverts materials from landfills while helping protect regional waterways.

Built for Scale and Engineered for Performance

Our team has decades of experience designing complex industrial systems. Every detail of our process, from feedstock intake to discharge of treated wastewater, is engineered for efficiency, uptime, and long-term environmental benefit.

Measurable Climate Benefits

Every molecule of RNG we produce reduces the need to extract conventional natural gas, offsetting additional fossil fuel emissions. Also, capturing methane from waste prevents it from being released into the atmosphere.
