Toray succeeded in producing first fully renewable biobased PET fiber

November 18/2011

(Plastemart) -- Toray Industries, Inc. succeeded in producing laboratory-scale samples of the world's first fully renewable biobased PET fiber by using fully renewable biobased PET derived from biobased paraxylene from Gevo, Inc., a leading company in renewable chemicals and advanced biofuels. Gevo has succeeded in converting isobutanol, produced from biomass by employing its own highly effective production method that uses synthetic biology, to synthesize para-xylene employing conventional chemical process used in commercial operations.Toray used terephthalic acid synthesized from Gevo's biobased para-xylene and commercially available renewable mono ethylene glycol (MEG) as raw materials, and successfully produced the PET samples by applying a new technology and PET polymerization in June this year. This biobased PET has exhibited properties equivalent to petro-based PET in laboratory conditions.


Toray has also succeeded in the production of a fiber using this fully renewable biobased PET for the first time in the world. The success of this trial, albeit under laboratory conditions, is proof that polyester fiber can be industrially produced from fully renewable biomass feedstock alone. This is a significant step that would contribute to the realization of a sustainable, low-carbon society.


Perspectives of development of polymer markets, pricing issues and other important aspects will be discussed at The Polymers Summit-2011, which will be held in Moscow on November 30, 2011 at the Ritz Carlton Hotel. The Summit will be organized by MRC with the support of ICIS. The main idea of the Summit is to find a "the golden mean" between producers and converters. When producers receive exactly such margin of production, which helps them to invest in production expansion in order to substitute polymers imports, and the converters receive such price of feedstock that helps them to compete imported finished products. The Summit site gives an access to the live video of the Summit, speakers" presentations, as well as opportunities to ask questions or make appointments to any Summit partcipant.
