DNP acquires Sinoven Biopolymers

Sinoven Biopolymers (Philadelphia) and its proprietary technology for modifying polybutylene succinate (PBS) has been acquired by renewable chemical manufacturer DNP Green Technology (Princeton, NJ), in a bid by that company to "move down the value chain." Jean-Francois Huc, president of DNP Green Technology, said, "With the acquisition of Sinoven, DNP Green can now transform corn and other crops into a diverse range of renewable, biodegradable products, from coffee cup lids and disposable razors to automotive parts."


Sinoven, which has a sales office in Philadelphia and a manufacturing and formulation development facility in Shanghai, will also expand DNP's reach into China. Sinoven will also now have access to succinic acid and 1,4 butanediol produced by DNP Green; a supply arrangement it believes will drive down the cost of its modified PBS. DNP, which has offices in Princeton, NJ and Montreal, has formed a joint venture called Bioamber to scale up and commercialize its succinic acid technology. In December 2009, Sinoven and Bioamber signed a supply agreement for biobased succinic acid. The agreement called for Bioamber to be the exclusive supplier of biobased succinic acid for Sinoven. Bioamber's succinic acid is produced from wheat-derived glucose at a 2000-tonnes/yr facility in Pomacle, France.

Sinoven says its modified PBS has higher performance than some competitive biodegradable polymers, with heat resistance above 100°C and the ability to be processed in existing production equipment. The company also claims it will be the first to commercialize PBS with renewable content above 50%. Applications for Sinoven's PBS include foodservice coffee lids, cups, dishes, cutlery, straws, and stirrers, as well as consumer use products such as disposable razors, writing instruments, and cosmetics packaging.
