In Illinois, GROWMARK, Inc. has partnered with Optimus Technologies, Inc., to test biodiesel in five semi-tractors in GROWMARK’s Manito Transit fleet as a potential pathway for transitioning the entire fleet to low-carbon fuels as part of GROWMARK’s ongoing efforts to look for decarbonization opportunities within the GROWMARK System. Since the pilot began in the summer of 2023, thousands of gallons of biodiesel have been used in the five Manito Transit trucks. Kubsch also says the drivers of the trucks using biodiesel have detected no change in performance.
