Using low-cost waste for polyhydroxybutyrate bioplastics

from SPE Plastics Research Online

The harmful effects of synthetic plastics in the environment have been of increasing concern in recent years. This ecological awareness impelled development of new, eco-friendly materials, especially for single-use plastic items. Polyhydroxybutyrate is a biodegradable polyester synthesized by micro-organisms. It has attracted the attention of academics and industry because it has similar biodegradability characteristics to those of conventional thermoplastics. However, use of PHB is limited because of its thermal instability, excessive brittleness, and high production cost compared with synthetic plastics. Incorporating natural fibers into PHB appears a promising solution to these problems. more
