BIOGEST America has received a US order to build an agricultural biogas plant in South Dakota, it announced on 6 September.
The plant has a thermal output of 156,000 MMBTU per annum and operates on 224,000t of cow manure per year.
During the process, the manure is transformed into high-quality organic fertiliser that acts as a substitute for chemical products.
After the project is complete, the biogas generated by this manure will be captured, cleaned and converted into RNG.
The company said its proven biogas plant technology offers significant advantages in energy efficiency and operational safety as well as an easy and cost-efficient maintenance system.
“We are thrilled to have the opportunity to plan this anaerobic digestion project as a component of our new Full Circle Dairy. We are repeat partners with Brightmark for a simple reason: we know that we can trust them to get the job done,” commented Greg Van Ravenswaay, manager, Full Circle Dairy.
RNG is the only renewable energy source that can be carbon-negative, as it significantly reduces methane emissions from agricultural operations. BIOGEST’s RNG plants produce not only pipeline quality green gas but also an organic fertiliser that helps to lower the use of chemical fertilisers in agriculture.
