Codexis and Chemtex to Collaborate on Sustainable Detergent Alcohols for the Household Products Market

REDWOOD CITY, Calif. and TORTONA, Italy, July 28, 2011 /PRNewswire via COMTEX/ --

Codexis, Inc. (Nasdaq: CDXS) and Chemtex, a global technology and engineering Company wholly-owned by Italy's Gruppo Mossi & Ghisolfi ("M&G Group"), today announced a broad collaboration to develop and produce sustainable detergent alcohols for use in the household products market. The collaboration includes development of second generation detergent alcohols from cellulosic (non-food) biomass.

Detergent alcohols - a $6 billion worldwide market - are surfactants which stabilize mixtures of oil and water. They are widely used in laundry detergents, shampoos and other consumer products. Detergent alcohols today are made from non-sustainable palm kernel and petroleum sources.

The collaboration with Chemtex includes the following:

  • Development of a world-class process for the conversion of cellulosic biomass to sustainable detergent alcohols

The process will utilize Chemtex's break-through PROESA(TM) Pretreatment and Viscosity Reduction Technology with Codexis' proprietary CodeEvolver(TM) directed evolution technology to enable more cost-effective production of detergent alcohols from cellulosic feedstocks. Both elements--an efficient pretreatment and high performance enzymes--are required to enable commercial use of cellulosic feedstocks such as straw, sugar cane bagasse and energy crops to produce industrial products. The collaboration will focus on development of a technology package suitable for use with a wide variety of feedstocks. Under the terms of the agreement, Codexis will have exclusive rights to PROESA(TM) technology for the production of detergent alcohols.


  • Scale up of second generation detergent alcohols

Cellulosic sugars will be converted to detergent alcohols using a proprietary fermentation process developed by Codexis. The parties expect that this process will initially be piloted at Chemtex's R&D facility in Rivalta, Italy. Larger scale demonstrations are anticipated at Chemtex's 40,000 metric ton (88 million pound) per year cellulosic ethanol plant in Crescentino, Italy, that is expected to be operational in 2012.


  • Engineering services for Codexis commercial facilities

Chemtex is a global leader in chemical engineering and renewable processes. Chemtex will provide engineering services for the design and construction of Codexis commercial facilities for the production of detergent alcohols. Codexis will market products resulting from the collaboration.

"With this collaboration, Codexis has a fully integrated production process for converting cellulosic biomass to marketable, sustainable detergent alcohols," said Alan Shaw, Ph.D., Codexis President and Chief Executive Officer. "By combining Codexis' proven enzyme technology with Chemtex's leading technology and engineering design expertise, we are making significant progress towards production of commercial products from renewable feedstocks."

"We are very pleased to be working with Codexis in this important collaboration," said Mr. Guido Ghisolfi President and CEO of Chemtex. "PROESA(TM) is break-through technology that produces high quality cellulosic sugar from biomass with best in class opex and capex. Coupling PROESA(TM) with the unique features of Codexis' technology platform has the potential to make the production of detergent alcohols from biomass a reality.

"Codexis joins the list of leading biotech companies that has selected Chemtex's PROESA(TM) Process as their technology platform of choice to expedite the production of green chemicals from biomass. This is further evidence that PROESA(TM) is the break-through technology that the marketplace has been seeking in its drive for sustainability."
