COVID-19 UPDATE: Due to the economic fallout of the ongoing COVID-19 pandemic, we are forced to make some operational changes. Over the next month, POET biorefineries in Chancellor, South Dakota and Ashton and Coon Rapids, Iowa will temporarily idle production. In addition, the biorefinery in Shelbyville, Indiana will be delaying the startup of production.

POET has faced difficult times in the past and we have proven our resiliency. We value the partnership and relationship we have with all of our producers and look forward to getting back to normal operations. In the meantime, please reach out to your POET Grain representative if you have questions.

POET Biorefining, located in Caro, MI, produces 53 million gallons of ethanol annually and is the 14th ethanol plant built by POET which began building ethanol plants in the 1980s. With cooperation of the many local leaders and in partnership with members of the agricultural community and the state political leadership, POET Biorefining is excited to bring a new kind of value-added agriculture to the state of Michigan.

Ethanol production by POET Biorefining - Caro consumes approximately 18 million bushels of corn from the region and provides not only an environmentally friendly fuel, but also a valuable high quality livestock feed for local, regional and national markets.

The plant was honored with the Michigan Agri-Business Association’s 2011 Green Agri-Business Designation for efforts including a total water recovery system to eliminate wastewater discharge, a waste heat recovery system that recycles both heat and water, a Load Toad DDGS loader to get more product onto each rail car, and a recycling program.
