Bioplastics: requirement for sustainability

Abstract

The petrochemical-based plastics are causing a strong challenge for the natural ecosystem leading to global environmental pollution due to their non-biodegradable nature. Hence, the requirement of alternative materials possessing environmental advantages received attention and leads to the development of bioplastics. Definition of bioplastics is not universal but broadly it can be defined as biodegradable plastic derived from biodegradable substances. Although, all types of bioplastics are not biodegradable, still their many advantages towards the environment cannot be ruled out and hence, their applications in varied areas have increased many-folds world-wide. Bioplastics are being used in rigid and flexible packaging materials, food and drinks containers, dining utensils, electronic devices, automotive and airplane parts, cable sheaths and casings, noise and thermal insulation panels and many more. The list is growing up. Bioplastics have shown their potential for a sustainable society and presents some advantages such as lower carbon footprint, energy efficiency, and eco-safety. This article discusses the basic information, sources, biodegradability, and applications of bioplastics.
