Abstract |
Generation of voluminous single -use plastic waste and byproducts from agricultural harvests such as rice straws (RSs) are major global challenges due to their disposal issues, contributing to greenhouse gas emissions, and affecting the ecological system with threats to human health. A scalable, low-cost, and ecofriendly strategy for fabricating cellulose -silica -based drinking straws, free from microplastics and adhesive, through strategic valorization of RS is reported. Functionalization by delignification- cum- crosslinking of RS leads to development of straws with high water stability ( similar to 5 days), solvothermal stability (0 degrees C- 95 degrees C), tensile strength (128 MPa), low migration values (<60 mg/kg), improved biodegradability ( similar to 126 days) with reduced wettability and hydrophobicity. RS drinking straws show antibacterial, selfcleaning, self -healing, anti -fizzing, reusable, and generate significantly lower carbon footprint (<99.8% and <53.34% global warming potential than metal and polylactic acid straws). Repurposing of agrowastes from farms to commercially viable drinking straws which biodegrades after its consumption achieves the goal of circular economy and sustainable development. |
