Missouri State Senator Mike Parson, a Republican running for Lt. Governor in 2016, toured the POET Biorefining Plant last Wednesday in Laddonia with POET General Manager Steve Murphy. The stop was one of several during a tour of ethanol and biodiesel plants across Missouri. About a :45 minute informational session was held with POET staff before Sen. Parson toured the plant, which is about to celebrate its 10th anniversary.
