The increase in the consumption of polymer materials, including polyurethanes, created not only convenience and comfort but also problems with the equally rapid increase in their waste, as well as the need for raw materials for polymer synthesis, which were and still are mostly obtained from petrochemicals. The development of renewable polyols has been assumed as a way toward more sustainable polyurethane production. This review presents an overview of polyols' synthesis for polyurethane foam production evolving from the first- to the fourth-generation biomass feedstock, mainly from natural oils. In the future, more studies with Life Cycle Sustainability Assessment would be a significant contribution to evaluating the sustainability of the approach to produce polyurethane foams from renewable polyols. At the moment, the big unknown is the fourth generation — genetically modified oils.

包括聚氨酯在内的聚合物材料消耗的增加，不仅带来了便利和舒适，而且带来了废物同样快速增加的问题，以及对聚合物合成原材料的需求，而这些原材料过去和现在仍然主要来自于聚合物合成。石化产品。可再生多元醇的开发被认为是实现更可持续的聚氨酯生产的一种方式。本综述概述了从第一代生物质原料发展到第四代生物质原料的用于聚氨酯泡沫生产的多元醇合成，主要来自天然油。未来，更多的生命周期可持续性评估研究将为评估用可再生多元醇生产聚氨酯泡沫的方法的可持续性做出重大贡献。目前，最大的未知数是第四代——转基因油。
