Polyhydroxyalkanoates, or PHAs, are linear polyesters produced in nature by bacterial fermentation of sugar or lipids. More than 150 monomers can be combined within this family of polymers to produce materials with different, useful properties. These plastics are biodegradable and are used in the production of bioplastics. They can be either thermoplastic or elastomeric materials, with melting points ranging from 40 to 180 °C. The mechanical and biocompatibility of PHA can be changed by blending, modifying the surface, or combining PHA with other polymers, enzymes, and inorganic materials, making a wide range of applications possible.

EcoPure products should biodegrade in any active microbial environment, including lakes, oceans, and streams. Our testing confirms that EcoPure-treated products biodegrade in both aerobic and anaerobic environments. Marine testing has been conducted on EcoPure treated textile products, with results showing biodegradation.
