Bioplastics for Sustainable Development

Abstract

Petrochemical plastics are nonbiodegradable synthetic organic polymers. It has various applications and become an essential part of our daily lives. However, the improper disposal of plastics results in the deaths of millions of animals annually and the reduction of soil fertility and also causes severe environmental pollution. The vast consumption and accumulation of plastics have become one of the major problems throughout the world. In response to these problems, there has been considerable interest in the development and production of biodegradable microbial bioplastics which can serve as a potential alternative to petrochemical plastics. Polyhydroxyalkanoates (PHAs) are microbial bioplastics that belong to a family of biopolyesters, primarily composed of R-3-hydroxyalkanoic acid monomers unit. Wide varieties of microorganisms have been reported to synthesize polyhydroxyalkanoate (PHA) and its copolymers as intracellular inclusion under carbon-rich and other nutritional limiting conditions. PHA and its copolymers have attracted researchers and industries because of their potential use as biodegradable and biocompatible thermoplastics. It has remarkable applications in the field of tissue engineering, drug delivery, pharmaceutical, and packaging industry. The development of microbial bioplastics and their products would help to maintain the sustainability of the environment and to reduce the emission of greenhouse gases. This chapter is focused on the updated information on microbial bioplastic (PHA) production and its progress in biotechnological and other industrial applications.
