Biogest America is building an agricultural biogas plant in Hurley, South Dakota. The company is providing engineering, design and equipment for a four-tank system with Brightmark in collaboration with Full Circle Dairy. The project will operate on 224,000 tons of cow manure each year. The cow manure would produce high quality organic fertilizer to be used as a substitute for chemical products. After the plant is built, the biogas would be captured, cleaned and turned into RNG at the farm. RNG is the only renewable energy source that can be carbon negative, reducing methane emissions from ag operations. The first gas production is expected in the first quarter of 2023.
