Method & Evidence

AimTo investigate the feasibility of extracting cellulose microfibers from waste fallen leaves and their subsequent use in fabricating a biodegradable composite film with enhanced mechanical properties for packaging.
MethodExperimental research and material characterization
ProcedureCellulose microfibers (CMFs) were extracted from dried fallen leaves using an alkaline peroxide treatment. These CMFs were then combined with polyvinyl alcohol (PVA) at varying concentrations (5-15%) via solution casting to produce composite films. The mechanical properties (tensile strength, elongation at break) and biodegradation rates of these films were evaluated.
