Toray, Genomatica advances bio-PBT development

Here is another exciting news, this one from Genomatica and Japanese chemical firm Toray. The companies said Toray has successfully produced prototypes of molded partially bio-based PBT (polybutylene terephthalate) engineering plastic components using Genomatica's bio-based 1,4 butanediol (BDO). PBT is currently produced by polymerizing petroleum-based BDO and terephthalic acid (TPA).

Sample molded parts made with partial bio-based PBT

Toray has been working on the biobased PBT with Genomatica for more than two years and produced the first PBT pellets made with bio-BDO samples in February 2011. Toray said the partially bio-based PBT has physical properties and formability equivalent to PBT made with petroleum-derived BDO.
