Iowa could soon use the byproducts from two of its biggest industries – crop and livestock production – to create a new market in renewable fuel production, according to a report in Midwest Energy News.
This potential new market is the result of policy and economics. Last summer, a revision to EPA’s Renewable Fuels Standard (RFS) increased the value of biogas in the fuel marketplace. The revision means biogas will be added to the list of advanced cellulosic biofuels which refineries must either produce or purchase credits for. The quantity of cellulosic fuels that must be blended with gasoline is expected to increase over the next eight years which means higher prices for renewable fuels. Amanda Bilek, government affairs manager at the Great Plains Institute in Minneapolis, said this change to the RFS has created a new market for fuels produced using manure and other organic waste.
A 2013 report by the National Renewable Energy Laboratory found that Iowa led the nation in manure production. The study also examined methane content in not just manure but also wastewater, landfills and industrial as well as commercial organic waste. The Hawkeye State ranked 8th nationally for methane generation potential.
Iowa State University teamed up with EcoEngineers out of Des Moines to create an interactive map and website which calculates the amount of methane-containing waste within up to a 50-mile radius. Biogas production in Iowa has been modest thus far but officials expect the industry to grow in the coming years.
