POET Biorefining, located near Cloverdale, IN was purchased by POET on June 29, 2010 and celebrated its grand opening event on March 15, 2011. The 92 million gallon per year facility was previously operated by Altra Biofuels.

POET has installed the company’s proprietary process technology and improved the original plant design. The approximately $30 million in upgrades include BPX, POET’s patent-pending fermentation process which uses enzymes instead of heat, reducing energy usage by 10-15 percent. In addition, POET installed a water recovery system and new pollution control equipment. The plant began operations on March 22, 2011.

In October 2019, POET was forced to idle the Cloverdale plant due to an unsustainable market environment for ethanol production brought around by EPA mismanagement of the Renewable Fuel Standard. At that time focus shifted to management of a grain elevator operation.

POET Biorefining - Cloverdale is pleased to be part of the Cloverdale, IN community.
