Bioplastic production in terms of life cycle assessment: A state-of-the-art review

This review explores the sustainability of bioplastics through the lens of life cycle assessment (LCA), examining feedstock sourcing, production pathways, environmental impacts, and end-of-life options. The notice identifies minor errors in the abstract and replaces two figures related to the conversion of cellulose into cellulose triacetate and the corresponding NMR characterization.

Within this broader context, the article provides a detailed overview of cellulose acetate, describing its production from cellulose through acetylation and its use in applications such as textiles, packaging, filtration membranes, photography films, biomedical materials, and cigarette filter tow. The authors compare bio-based plastics with conventional fossil-based plastics and discuss how circular economy principles, renewable feedstocks, and effective waste management can improve material sustainability.

For cellulose acetate, the review highlights its strong potential as a bio-based and biodegradable material with a favorable environmental profile when produced through greener processing routes. The authors note that cellulose acetate can degrade through chemical and biological pathways, ultimately yielding cellulose- and acetate-based breakdown products, although degradation rates depend on both material structure and environmental conditions. The article emphasizes the importance of life cycle thinking, including responsible end-of-life management, to maximize sustainability benefits. These findings are particularly relevant for manufacturers, regulators, and product developers seeking renewable material solutions that support circular economy objectives while balancing performance, environmental impact, and resource efficiency.
