Renewable Dairy Fuels Kicks off Construction of Indiana Biogas Facility


Renewable Dairy Fuels (RDF), a business unit of AMP Americas, has announced that construction has begun on what the company calls the U.S.’ biggest on-farm anaerobic-digester-to-vehicle-fuel operation.

Located in Fair Oaks, Ind., the dairy project will be the company’s second biogas facility producing renewable natural gas (RNG) from dairy waste for transportation fuel.

The new facility, expected to be operational this summer, will be 50% larger than RDF’s operation at Fair Oaks Farms in northwest Indiana. Amp Americas received the first dairy waste-to-vehicle fuel pathway certified by California’s Air Resources Board (CARB) for Fair Oaks Farms. The project was also awarded a Carbon Intensity score of 254.94 gCO2e/MJ, the lowest ever issued by CARB, Amp Americas says.

The new site is located in Jasper County, just a few miles from Fair Oaks Farms. Every day, three digesters located at three dairy farms will convert 950 tons of dairy waste from 16,000 head of milking cows into 100% renewable transportation fuel. The RNG will then be injected into the NIPSCO pipeline. Each of the digesters is a Mixed Plug Flow digester designed and built by DVO Inc.

“Transportation is now the largest source of greenhouse gases in the U.S. and a major source of smog-causing pollution. It is more important than ever to drive further adoption of clean and efficient domestic RNG within the trucking industry,” says Grant Zimmerman, CEO of AMP Americas. “There isn’t enough RNG being produced to meet customer demand. Our new project will help make strong headway toward closing the supply gap.”
