Abstract
Polyhydroxyalkanoates (PHA) are the most commemorated of biodegradable bioplastics due to good physical and mechanical properties, fast and complete biodegradability. PHA is a group of biodegradable and biocompatible polymers, which consists of more than 9 groups, including polyhydroxybutyrate (PHB) and polyhydroxyvalerate (PGV). They are synthesized enzymatically by bacteria as a reserve source of energy. PHA are thermoplastic linear polyesters based on aliphatic hydroxyacids and consist of more than 9 groups. Among the most significant representatives include polyhydroxybutyrate (PHB) and polyhydroxyvalerate (PGV). PHB derives from renewable sources and can degrade in different environments to carbon dioxide and water. PHB properties can be varied by mixing it with other polymers. For example, blending PHB with PLA, you get a good blend for 3D printing and package production. And blending PHA with PBAT make the polymer more flexible. The main field of application of PHA-plastics is the manufacture of bulk products, packaging and 3D printing, depends on mixing PHB with various polymers. And also there are some fields of its using which will be available as piece and mass goods only with significant marketing support.
