Amp Americas, a pioneer in the renewable transportation fuel industry, on March 10 announced that its fourth biogas facility producing renewable natural gas (RNG) from dairy waste is now operational and has begun delivering RNG into the Alliance natural gas pipeline to be used as transportation fuel. Located in Morris, Minnesota near the state’s western border, the new plant is Amp Americas’ largest dairy RNG project to date and the state’s first on-farm biogas-to-vehicle fuel facility. With this project, Amp Americas has now developed dairy RNG production on 12 dairies with over 66,000 cows.
