Mitsubishi ZEBREXTM Technology to be Implemented by Aemetis to Reduce Energy Use and Lower Carbon Intensity of Biofuel

Mitsubishi ZEBREXTM Technology to be Implemented by Aemetis to Reduce Energy Use and Lower Carbon Intensity of Biofuel


CUPERTINO, CA, USA – August 30, 2018 – Aemetis, Inc. (NASDAQ: AMTX) and Mitsubishi Chemical Corporation (MCC) announced today that Aemetis will be implementing the Mitsubishi Chemical Corporation ZEBREXTM membrane dehydration system at the 60 million gallon per year Aemetis fuel ethanol plant in Keyes, California. The sales transaction involves a subsidiary of MCC, Mitsubishi Chemical America, Inc. The Aemetis plant upgrade is the first ZEBREXTM system installation in North America and is the largest implementation of the ZEBREXTM system worldwide.


The upgrade from the traditional Pressure Swing Adsorption (PSA) dehydration process to the ZEBREXTM system can reduce energy consumption in the production of biofuels by up to 25%, increasing production capacity while reducing the usage of fossil fuel-based energy and lowering the carbon intensity (CI) of ethanol produced at the plant. The unit will be designed and fabricated for Aemetis by ICM, Inc., headquartered in Colwich, Kansas, a leading ethanol technology provider. The Aemetis plant upgrade is the first ZEBREXTM installation delivered by MCC’s strategic engineering partner, ICM, in North America.


“Aemetis is a leader in the innovation and adoption of new technologies in both traditional and advanced biofuels,” stated Hiroyuki Kakiuchi, Manager of the ZEBREXTM product line at Mitsubishi Chemical Company in Tokyo, Japan.  “The ZEBREXTM system will allow the ethanol produced by Aemetis to  use  significantly less natural gas; reduce carbon emissions by approximately 16,000 tons per year; and provide increased ethanol production, achieving a lower carbon intensity biofuel that supports the goals of the California Low Carbon Fuel Standard (LCFS) and the US Renewable Fuel Standard (RFS).”


“The implementation of the Mitsubishi ZEBREXTM technology at the Aemetis Keyes plant is an excellent example of how the biofuels industry is utilizing advanced technology to reduce production costs and lower carbon emissions while increasing revenue per gallon and expanding capacity at both traditional and advanced ethanol production plants,” said Eric McAfee, Chairman and CEO of Aemetis.


The ZEBREXTM system has been installed in approximately 70 alcohol production plants worldwide.  The system is a state-of-the-art, continuous membrane dehydration technology to separate water from ethanol for purification into fuel quality biofuel at lower cost than the energy-intensive PSA units commonly used at ethanol plants.
