On account of the irreversible environmental damage caused by the utilization of non-renewable raw materials in industrial production, since the end of the twentieth century, the interest in replacing the traditionally applied petroleum-based starting compounds in the polyurethane production by more sustainable feedstocks has grown enormously. Such pursuit of Green Chemistry has been fostered by the implementation of a set of national and international initiatives and stricter regulations, especially in the field of adhesives. In this respect, the latest advances in the production of bio-based polyurethanes are collected in this review. Thus, after a brief introduction to this subject and main tendencies towards the production of more sustainable polyurethanes, the first section reviews the feasibility of manufacturing polyurethanes from a range of natural platforms, including lignocellulosic biomass and vegetable oils, whether modified or in their original form, along with some industrial wastes. Afterwards, the hitherto considered synthetic routes for the preparation of greener polyurethanes are assessed, encompassing waterborne, radiation-curable and non-isocyanate polyurethane techniques. Finally, the last section focuses on the research advancement on the synthesis, properties and different uses of bio-based polyurethanes specifically implemented in the field of adhesives.

由于工业生产中不可再生原材料的使用对环境造成不可逆转的破坏，自20世纪末以来，人们越来越有兴趣用更可持续的原料代替聚氨酯生产中传统使用的石油基起始化合物增长巨大。对绿色化学的追求通过实施一系列国家和国际倡议以及更严格的法规，尤其是在胶粘剂领域，已经促进了这一趋势。在这方面，本综述收集了生物基聚氨酯生产的最新进展。因此，在简要介绍了该主题以及生产更具可持续性的聚氨酯的主要趋势之后，第一部分回顾了从一系列天然平台（包括木质纤维素生物质和植物油，无论是改性的还是原始形式）生产聚氨酯的可行性。 ，以及一些工业废物。之后，评估了迄今为止考虑的用于制备绿色聚氨酯的合成路线，包括水性，辐射固化和非异氰酸酯聚氨酯技术。最后，
