Renewable Dairy Fuels, a business unit of Amp Americas, has expanded production at its biogas operation at Fair Oaks Farms by 30%. 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% 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, Ind., 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 more than 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.”

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.
