| Abstract | Plastic pollution remains a pressing issue in Thailand, where only a fraction of the2 million tonnes of plastic waste generated annually is recycled, leaving much to accumulate inwaterways and lead to water pollution. At the same time, invasive water hyacinth (Eichhorniacrassipes) clogs waterways and disrupts ecosystems, while discarded pineapple (Ananascomosus) crowns contribute to agricultural waste and environmental degradation. This studyextracted cellulose from water hyacinth petioles and pineapple crowns using NaOH and NaOCltreatments, then combined it with cassava starch, chitosan, and glycerol. Two biomass ratios (3:1and 1:1) were tested under varying drying and refrigeration conditions. The optimal conditions,2-week drying with a 3:1 ratio, achieved maximum strength (2.91 ± 0.11 N) after 24-hourrefrigeration, while 1-hour refrigeration is recommended for improved elasticity. FTIR analysisshowed O – H (3356 cm⁻¹), C – H (2938 cm⁻¹), C = O (1641 cm⁻¹), C – O (1017 cm⁻¹), andβ-1,4-glycosidic (927 cm⁻¹) confirming cellulose preservation; other peaks verified integrationof other components. A water degradation was performed and showed that the plastics from alltreatment groups had an average mass loss of 47.7% submerged 48 hours in water at 25 °C.The lightweight, flexible bioplastic is suitable for single-use applications with high watercontact such as compostable bags, food packaging, and seedling trays. |
