The material of garbage bags, polyethylene, does not decompose under natural environmental conditions, leading to long-term environmental pollution, necessitating the urgent development of environmentally friendly and biodegradable materials. Poly(butylene adipate-co-terephthalate) (PBAT) is a typical biodegradable polymer with similar mechanical strength, flexibility, and high elongation to conventional polyethylene, but it is expensive and not readily available. The blending of starch or cellulose-based materials can potentially reduce costs, but exposure to moisture can lead to stickiness or slow biodegradability, presenting additional problems. In this study, we observed changes due to alkali post-treatment by converting the cellulose derivative-based garbage bag with slow biodegradability into cellulose and conducting simultaneous reactions of hydrolysis of the polyester for low molecularization. This research was funded by the Ministry of Trade, Industry and Energy of Korea. (grant number: 20020236).
