The fully biodegradable disposable spoon is an environmentally friendly tableware product developed by Zaozhuang Tianyao Starch Technology Co., Ltd. for scenarios such as food delivery, fast food chains, group meal distribution, airline catering, and daily household use. The product is mainly made of biodegradable materials such as polylactic acid (PLA) and corn starch, and is produced through injection molding technology. Under industrial composting conditions, it can be completely decomposed by microorganisms into carbon dioxide and water, with no plastic residue. It is an ideal green alternative to traditional disposable spoons made of polypropylene (PP) and polystyrene (PS). The product has excellent properties such as high rigidity, heat resistance, non-toxic and odorless, and smooth surface, which are suitable for dining needs of various hot and cold foods. It fully meets the environmental protection requirements of the national "plastic ban" and the green transformation of the catering industry.
