Utilization of Disposable Paper Cups for Production of Cellulose Acetate Based Film
Summary
Researchers investigated the conversion of disposable paper cups -- a common food service waste stream with a polyethylene plastic lining -- into cellulose acetate film as a sustainable alternative to conventional plastic films. The study characterized the resulting biopolymer film for its properties and evaluated the approach as a strategy for valorizing paper cup waste.
The aims of research to explore the conversion of disposable paper cups, commonly used in the food and beverage industry, into cellulose acetate film. The increasing environmental concerns regarding plastic waste and the desire for sustainable alternatives have led to the investigation of utilizing cellulose-based materials. Cellulose, a biopolymer derived from plant-based sources, is the primary component of paper cups. Through a series of chemical processes, cellulose fibers are extracted from the paper cups and subsequently acetylated to form cellulose acetate. Cellulose acetate is a biodegradable and versatile material with various applications in packaging, textiles, and films. The project involves experimental work to extract cellulose fibers from the paper cups, optimizing the acetylation process, and fabricating cellulose acetate films through casting. The cellulose acetate films exhibit favourable properties, including good mechanical strength and thermal stability. These properties make cellulose acetate films a potential alternative to conventional plastic films, offering environmental benefits and promoting sustainability. The project highlights the importance of utilizing waste materials and transforming them into value-added products. By diverting waste from landfills and reducing dependence on conventional plastics, the project contributes to the promotion of a circular economy and sustainable practices.

Recovery of Cellulose Acetate from Spent Cigarette Filters by Green Solvents for Production of Polymer Films
Researchers developed a sustainable method for recovering cellulose acetate from spent cigarette filters — a persistent microplastic and chemical pollution source — using green solvents including deionised water, sodium chloride solutions, and ethanol under varying temperature and concentration conditions. They found that 75% ethanol was most effective for recovery, and characterised the purified material by FT-IR, TGA-DSC, NMR, and FESEM for use in producing new polymer films.
