Why Renewable Energy?


ZEBREX Soc Med Image9.27.18

Mitsubishi Chemical Corporation (MCC) and ICM are collaborating to provide “ZEBREXTM” to the fuel ethanol industry in the United States. 

This cooperation combines MCC’s proven ZEBREX™ membrane product with established production in Japan with ICM’s ability to integrate and engineer new technologies into the ethanol industry


ZEBREX™ is a cutting-edge zeolite membrane dehydration process. Ethanol and water are separated by the precise selectivity of the zeolite to produce 99.8% purity ethanol and recycle water in a single pass.

ZEBREX™ improves production capacity and reduces energy costs through the use of proven state-of-the-art zeolite membrane dehydration technology.

What ZEBREX™ can do?

  • Add incremental drying to the process
  • Completely replace mole sieve technology
  • Dry the regen instead of recycling back to the rectifier
  • Dry ethanol to EU or other specification.
  • Reduce the energy used in an ethanol process


ZEBREX™ is a trademark of Mitsubishi Chemical Corporation.


Thin Stillage Solids Separation System™

Thin Stillage Solids Separation Systems™ (TS4™) is a revolutionary technology with multiple design configurations. TS4™ provides opportunities for separating the stillage process stream into its most valuable components – protein, solubles and oil.

Enhanced Capabilities
• Increase dryer capacity

• More efficient centrifuge separation
• Improve evaporator operation 
• Increase plant throughput

Benefits of TS4™
• Debottleneck the plant by increasing dryer and evaporator capacity

• Improve plant profitability by reducing or eliminating low price excess syrup sales
• Provide cleaner backset/cook water
• Reduce cost by reducing energy, evaporator and water consumption

Fiber Separation Technology™ / Fiber Separation Technology Next Gen™

FST Social media

FST™/FST Next Gen™ is the next layer of ICM technology following SMT™/SMTV2™. This progressive pre-fermentation separation system is designed to remove fiber prior to fermentation. Removing the fiber provides plants with the ability to concentrate process streams and to better utilize the capacities of fermentation and distillation. With this patented process, plants are able to maximize throughput.

 Benefits of FST™ / FST Next Gen™

  • Up to 25% corn distillers yield increase
  • Up to 14% ethanol capacity increase
  • 45% reduction in exchanger pressure
  • Less energy usage per gallon than competitors' offerings
  • Enhanced operational efficiency
  • Ability to produce Hi-Pro DDG, a high protein feed for poultry, swine, and aquaculture, selling at a significant premium over DDGS
  • Platform for additional value from Gen 1.5 cellulosic ethanol technology


Generation 1.5: Grain Fiber to Cellulosic Ethanol Technology™


Enhanced Capabilities

• Gen 1.5 has been proven in both pilot (15,000 gallon) and production (585,000 gallonS) fermentors in runs up to 1000 hours 

•In many cases, ethanol produced by Gen 1.5 process can be made at a lower cost of production than the traditional Generation 1.0 starch-based ethanol process

•Collaboration with two world-leading  biotechnology companies, DSM and Novozymes

Benefits of Gen 1.5

•Additional 7-10% increase in cellulosic ethanol

•Additional 20% increase in oil recovery 

•No feedstock collection required – fiber handles far easier than agricultural residue

•Fully-integrated solution reduces costs – capex cost of $3-5 per gallon compared to $10-15 for cellulosic Generation 2.0

•Capture D3 RINs, cellulosic tax credits and California Low Carbon Fuel Standard Credits – may result in added value as high as $3.00 per gallon above corn ethanol prices

•Produces a high protein DDGs mix – may bring added value to animal feed

•Flexible rollout

•Patent-pending technology
