Iowa Researchers see Wasted Potential in Agricultural Renewable Fuels
A research team led by Iowa State University is studying ways to increase farmers’ interest in — and profits from — biofuels made from manure and other low-value biomass.
Anaerobic digestion, as it’s known, processes agricultural waste into renewable natural gas using an oxygen-free form of combustion. The gas then can be used on site or refined and distributed through existing natural gas pipelines.
