Cellulose acetate-based materials for water treatment in the context of circular economy

This review examines the role of cellulose acetate as a sustainable membrane material for water treatment within the framework of the circular economy. The article explores how cellulose acetate’s biodegradability, availability, and chemical versatility make it an attractive alternative to conventional petroleum-based membrane materials. It surveys recent advances in cellulose acetate membranes and composites for water purification, focusing on their design, functionalization, and application in the removal of heavy metals, pharmaceutical contaminants, dyes, salts, and other pollutants from water streams.

The review highlights that cellulose acetate membranes can achieve enhanced separation performance when modified with nanoparticles, functional molecules, or complementary polymers, enabling improved pollutant removal, antifouling behavior, and membrane durability. The authors conclude that cellulose acetate offers significant potential for supporting water reuse and resource efficiency, key objectives of circular economy strategies. At the same time, challenges related to mechanical performance, fouling resistance, large-scale functionalization, and long-term process efficiency remain important areas for further development. These findings are relevant for industry and researchers seeking lower-impact water treatment technologies that combine renewable materials, membrane innovation, and improved environmental sustainability.
