(Radio Iowa) – An 80-million dollar U-S-D-A grant will provide new incentives to farmers in Iowa and Missouri who switch from planting corn and soybeans on marginal cropland — and grow native grasses and prairie plants to harvest instead. Roeslein Alternative Energy of St. Louis, Missouri, secured the grant with help from Iowa State University and the Iowa Soybean Association. Roeslein spokesman Brandon Butler says the company, which started in 2012, has been capturing energy from livestock waste.
“We’re able to tarp over those lagoons, capture all those gases, bring them to a centralized (location) and then we separate those molecules,” he says. “We upgrade the methane into…renewable natural gas — called RNG — and we directly inject that into the natural gas grid.” The new initiative plans to make renewable natural gas from the plant material harvested from local fields.
“The biogas is really, really important to rural America and agricultural communities,” Butler says. “This is reallly our chance to interact with this extreme push towards a more sustainable future.” Butler says this new project also fits with the company’s mission.
“We want to create processes that are good economically, they’re good environmentally and they’re good for wildlife,” he says, ‘because when it’s good for wildlife, it’s good for us as well.” The five-year pilot project will compensate farmers for growing restored grasses and prairie plants, which have deep roots that store carbon in the soil. The harvested biomass will be combined with manure in facilities that ultimately produce renewable natural gas.
