Biobased polymers of plant and microbial origin and their applications: A review

This review explores the growing role of biobased polymers as sustainable alternatives to conventional petroleum-derived plastics, with particular attention to materials of plant and microbial origin. Within this broader context, cellulose acetate is highlighted as an important cellulose-derived biopolymer produced through chemical modification of cellulose and valued for its biodegradability, biocompatibility, and versatility.

The article reviews major classes of biopolymers, their sources, production and purification methods, and their expanding applications across packaging, medicine, agriculture, cosmetics, and other industrial sectors.

For cellulose acetate, the review underscores its significance as a renewable material that extends the functionality of natural cellulose while retaining many sustainability advantages. The authors identify cellulose acetate among the cellulose derivatives used in pharmaceutical, biomedical, packaging, and film applications, reflecting the broader trend toward replacing fossil-based polymers with bio-based alternatives. The review also notes ongoing challenges associated with biopolymer adoption, including performance optimization, production scalability, and end-of-life management. These findings are relevant for industry and researchers because they position cellulose acetate within a rapidly evolving bioeconomy focused on reducing environmental impacts while enabling innovation in high-value products and sustainable material technologies.
