How anaerobic digestion works
Our farmers are an integral part of helping us Reimagine Waste—they care as much about the environment as we do, which is why we’re proud to partner with various farmers throughout the nation.
At Brightmark, we capture the methane released from organic waste and convert it into renewable natural gas, better known as “RNG.”
By working with prominent farmers all over the United States, we started to create renewable natural gas. This renewable power was consciously developed with nature and the world around us in mind.
Organic waste has evolved into a resource that we can use for various new things—including heating our water, powering our homes, running our cars, all helping to lower greenhouse gas emissions and protect the planet that we all call home.
Reimagining organic waste
“With Brightmark, we now generate energy that was being wasted before—we are preventing waste and creating usable products.”

Our RNG projects are California Air Resources Board Certified
Our renewable natural gas projects decrease the carbon intensity of transportation fuels and are California Air Resources Board (CARB) certified.
Our RNG projects are certified by the Environmental Protection Agency
Our Helios, Yellowjacket, Augean, and Demeter renewable natural gas projects participate in the Renewable Fuel Standard Program—reducing greenhouse gases and expanding the nation’s renewable fuels sector.
How renewable natural gas is made
Renewable natural gas (RNG) is natural gas produced from organic waste like food waste and animal plant-based materials. The significant sources of RNG are landfills, animal manure, and solid waste extracted during wastewater treatment. The gas is considered “renewable” because it is created by continuously produced waste and is naturally occurring as part of the decomposition process. Anaerobic digestion technology captures raw biogas, cleans, upgrades, and compresses it into RNG.
Clean air, healthy soil, and new products. That’s what our RNG efforts are all about. We convert “waste” into biogas, biofertilizers, compost, electricity, and reusable water using organic waste like food and manure.
