Filed under: Ethanol, Manufacturing/PlantsEthanol company Poet (formerly Broin) today announced something called Ingreenuity, a "new initiative to enhance the environmental performance of ethanol." The first step in the process is to decrease the amount of water it takes to make the biofuel down to
2.33 gallons per gallon of ethanol, a 22 percent reduction compared to today's water usage rates. Instituting this reduction, called the Total Water Recovery process, is expected to take five years.



The main way Poet plans on reducing the amount of water used is by recycling cooling water instead of discharging it. Since it started making ethanol in 1988, Poet claims to have reduced the amount of water needed by 80 percent. Future steps in Ingreenuity are greenhouse gas reductions and the development of bio-based products.



Of course, Poet is not the only ethanol producer out there trying to limit the amount of water it takes to process feedstock into fuel. Coskata, for example, says that its cellulosic ethanol process requires less than a gallon of water for each gallon of ethanol it makes. Poet says it is willing to share its water reduction technology with other ethanol companies.
