Amp Americas Expands Landmark Fair Oaks Farms Dairy RNG Project to Increase Biogas Production

With the Two Largest On-Farm Biogas Operations in the Country, Amp Americas Now Producing 5 Million Gallons of RNG Annually


CHICAGO (February 21, 2019) – Renewable Dairy Fuels (RDF), a business unit of Amp Americas, announced today that it has expanded production at its biogas operation at Fair Oaks Farms by 30 percent. The Indiana project was the first dairy biogas-to-transportation fuel project in the country and now has the capacity to produce over 2.3 million gallons per year of 100 percent renewable transportation fuel from dairy waste.

RDF’s Fair Oaks facility remains the second-largest dairy biogas-to-transportation fuel project in the country, bested only by RDF’s facility in Jasper County, Indiana, which came online in August 2018 as the largest in the nation.

With the completed expansion, the Fair Oaks project, which has been operating since 2011, now converts over 800,000 gallons of manure per day from 20,000 cows into renewable methane that is then captured, purified, and compressed to become RNG. The RNG is injected into the NIPSCO natural gas pipeline system to be used as transportation fuel.

“We are proud to bolster our production of clean, ultra-low carbon gas that increases our energy independence and substantially reduces greenhouse gas emissions, all while creating economic opportunities for rural communities,” said Grant Zimmerman, CEO of Amp Americas. “We’ve made revolutionary progress in our carbon reduction and renewable energy efforts, but this is just the tip of the iceberg.”

A pioneer in the renewable transportation fuel industry, Amp Americas continues to expand its national footprint and to invest heavily in dairy RNG projects by partnering with dairy farmers across the country to bring more low carbon gas to market. Amp Americas is currently producing 5 million gallons per year of RNG and working on several new projects that will increase that rate in 2019 and beyond. In addition, the company’s network of high performance, ultra fast-fill CNG fueling stations is now up to 20 and continues to grow. The company supports some of the largest CNG fleets in the country including UPS, US Foods and haulers for Select Milk and Dairy Farmers of America.

Amp Americas operates three business units: Renewable Dairy Fuels (RDF), Amp Renew and Amp CNG. RDF produces 100% renewable natural gas from dairy waste. RDF’s anaerobic digester at Fair Oaks Farms in Indiana received the first dairy waste-to-vehicle fuel pathway certified by California’s Air Resources Board (CARB). The project was also awarded a Carbon Intensity (CI) score of -254.94 gCO2e/MJ, the lowest ever issued by CARB. Amp Renew sources renewable gas from RDF and third party RNG developers to supply fuel to fleet customers through both owned and contracted station infrastructure. Amp CNG is a member of the Department of Energy’s National Clean Fleets Partnership which builds, owns and operates a growing network of CNG fueling stations for long-haul trucking fleets. Visit
