ABSTRACT
The increasing production and consumption of petro-based plastics raise significant environmental concerns due to their persistence and accumulation in ecosystems. Biopolymers, derived from renewable sources such as plants and microorganisms, offer a sustainable alternative to traditional plastics. These materials are moldable and recyclable through thermal processes, providing versatility for various industrial applications, such as commercial thermoplastic materials. This review provides a comprehensive overview of biopolymeric thermoplastics (b-bTPs), discussing their compositions, challenges, and recent advances. Key topics include the formulation of b-bTPs using additives and blends to improve their properties, the application of advanced techniques such as microcellular injection molding, the recyclability of b-bTPs foam parts, and future trends and prospects. This analysis highlights the potential of b-bTPs to replace conventional plastics in numerous applications, contributing to a more sustainable industry.
