DuPont this morning announced an expanded slate of renewably sourced polymers that will contribute to the company’s goal of doubling revenues from sustainable resources to at least $8 billion by 2015. Chief among the new offerings are Sorona EP thermoplastic resins, Hytrel RS thermoplastic elastomers, Biomax RS packaging resins and Selarâ VP breathable films. A key ingredient in Sorona EP is Bio-PDO, which is made at the recently inaugurated DuPont Tate & Lyle Bio Products facility in Loudon, TN. Bio-PDO replaces petrochemical based 1,3 propanediol (PDO) and/or 1,4-butanediol (BDO) in two glass-reinforced grades of Sorona EP that will initially be available. Sorona EP is compared to polybutylene terephthalate (PBT). Sampling is under way with broader availability expected in 2008. No disclosure was made on beta sites where the material is being tested.
Some of the biggest self-assembled building blocks and structures made from engineered DNA have been developed by researchers at Harvard's Wyss Institute. The largest, a hexagonal prism, is one-tenth the size of an average bacterium.
