A new plan to cut

The potential impact of this executive order goes beyond the volume of ethanol produced, however. Hallberg says that
Measuring life-cycle benefits would mean that no-till corn being sold to ethanol plants should receive a premium for sequestering carbon. It also means that ethanol plants selling fuel to
Prime BioSolutions happens to have a jump on emissions reductions at their low-carbon ethanol plant in Mead,
The Mead plant includes a feedlot with 30,000 cattle that eat the wet distillers grains, a byproduct of ethanol production. By being able to feed the distillers grains on site, the plant does not need to power a drier to prepare the grains for transport. Plants that are able to sell the distillers grains wet rather than dry can reduce emissions significantly circumventing drying machines.
The technology at the Mead plant goes farther, however, replacing fossil fuels with methanol given off by microbes' anaerobic digestion of the cattle manure.
Other methods are in place around the country to reduce greenhouse gas emissions at ethanol plants, including other ways to use manure for energy and a plant that supplements its energy needs with methane gas from a landfill.
