Anaerobic Digestion Plant To Use Ethanol Byproduct
HAZEN, N.D. (AP) — A Minnesota company is exploring building a plant in central North Dakota that would use bacteria to turn lignite, manure and the leftover liquid from ethanol production into natural gas and fertilizer.
St. Paul-based Proterra Bioconversion says the $6 million plant would be investor-funded, though it is asking the Mercer County Commission to help by issuing bonds for the project.
The plant would be built at an industrial site at the Mercer County Regional Airport near Hazen. Hazen Economic Development Director Duke Rosendahl says it could create up to 20 jobs.
