A bioplastic with significant potential for durable applications is the polyhydroxyalkanoates (PHA) family. PHB, for example, has high crystallinity and mechanical properties similar to polystyrene. P(3HB) has a melting point of 180°C and a wide in-use temperature range from -30°C to 120°C. One of the first durable applications was HBV/ECOFLEX compounded by PolyOne in 2008, and launched as the Design Ideas Range of Bathroom Accessories See more details at www.EcoGenLife.com. Interestingly, there are now about 75,000 metric tons of annual capacity globally to produce PHAs from five companies: Telles (USA), Tianjin Green Bioscience/DSM (China), Bio-on (Italy), Tianan Biologic Material Co. (China); and BioMatera (Canada). Nine other companies are conducting developmental work on PHAs, some with pilot plants: Micromidas (USA), Meredian (USA), Biomer (Germany), PHB Industrial (Brazil), Bioplastech (Ireland), the Salt and Marine Chemical Research Institute (India), Mitsubishi Gas Chemical (Japan), Shenzen Obioer Technology (China), and Kaneka (Japan). Most of these companies will initially push disposable applications, and then look for opportunities in higher-value durable applications.
