The world’s largest ethanol producer plans to decrease water use in the production of ethanol by 22 percent over the next five years, which would result in a savings of one billion gallons of water per year.

In a presentation to employees today, POET CEO Jeff Broin said the company is committed to producing ethanol as sustainably as possible and minimizing its impact on natural resources.

Water reduction is the first goal of Ingreenuity, POET’s new initiative to improve the environmental performance of ethanol. The reductions will come primarily through installing a proprietary process developed by POET engineers that recycles cooling water rather than discharging it. The process has recently been installed in three POET Biorefining locations which now average 2 to 2.5 gallons of water per gallon of ethanol.

To kick off the initiative, Broin announced that the POET Foundation has committed more than $420,000 to the non-profit Global Health Ministries (GHM) over the same five-year period as POET’s water reduction goal. A portion of the funds will help GHM repair, construct and maintain 90 wells in Nigeria that that will give more than 300,000 people access to pure water.
