Leather production for human protection has been an essential industrial activity since the start of civilization, yet classical leavering methods induce pollution of ecosystems by dyes, chromium-containing wastewater, and solid waste. Here, we review sustainable leather production using polysaccharides and modified polysaccharides, which are cheap, easy to obtain, and non-toxic. Polysaccharides include starch, chitosan, cellulose, and cyclodextrins. We discuss application for leather tanning, prevention of leather mildew, leather finishing and dyeing, and wastewater treatment. The leather properties meet the requirements of garment leathers, with tear strength higher than 18 N per mm and tensile strength higher than 6.5 MPa.

自文明开始以来，用于保护人类的皮革生产一直是一项重要的工业活动，但传统的脱皮方法会导致染料、含铬废水和固体废物对生态系统的污染。在这里，我们回顾了使用多糖和改性多糖的可持续皮革生产，它们廉价、易于获得且无毒。多糖包括淀粉、壳聚糖、纤维素和环糊精。我们讨论了在皮革鞣制、防止皮革霉变、皮革整理和染色以及废水处理方面的应用。皮革性能满足服装革要求，撕裂强度高于18N/mm，拉伸强度高于6.5MPa。
