Bioplastics PHAs

The extensive use of petroleum–based synthetic plastics is leading to various environmental problems such as ecological impact, and untreated plastic waste, particularly micro–plastic pollution. Bioplastics are, therefore, considered one of the prospective solutions to replace conventional plastics.

Polyhydroxyalkanoates (PHAs) are biomaterials that are accumulated intracellularly by bacterial cells in response to nutrient imbalances under environmental stress. Polyhydroxybutyrate (PHB) is a bioplastic that is of interest to research to find an alternative to fossil-derived plastics.

This mini-review article briefly introduces and classifies main types of bioplastic materials. The understanding of biobased content as well as biodegradability is also addressed. Lastly, three main classes of bio-based, biodegradable plastics which are thermoplastic starch (TPS), polylactic acid (PLA) and polyhydroxyalkanoate (PHA), are reviewed in terms of structure, properties, processing and applications.

AMB Express 2011, 1:11 http://www.amb-express.com/content/1/1/11 ORIGINAL Open Access Production of polyhydroxyalkanoates from waste frying oil by Cupriavidus necator Rob AJ Verlinden1, David J Hill1, Melvin A Kenward1, Craig D Williams1, Zofia Piotrowska-Seget2 and Iza K Radecka1* Abstract Polyhydroxyalkanoates (PHAs) are biopolymers, which can replace petrochemical plastics in many applications. However, these bioplastics are currently far more expensive than petrochemical plastics.
