Concerns are constantly growing about our dependance on plastics derived from fossil feedstock, leading to the development of bio-based alternatives. The bio-based polyester poly(ethylene furanoate) (PEF) has attracted increasing attention from the scientific community due to its potential to replace mass-produced poly(ethylene terephtalate) (PET), mainly used in the packaging, film and fibre sectors. PEF can be 100% bio-based since both its monomers can be produced from biological resources, and exhibits superior properties compared to PET, such as its mechanical and gas barrier properties. As PEF gets closer to being produced at a large scale and entering the plastic market, its end-of-life management should be carefully studied in order to mitigate its environmental footprint. This review focusses on the state-of-the art of the main scenarios related to polymers waste, including mechanical and chemical recycling, composting and incineration.

人们越来越担心我们对化石原料塑料的依赖，从而导致了生物基替代品的开发。生物基聚酯聚呋喃酸乙烯酯（PEF）由于其有潜力取代大规模生产的聚对苯二甲酸乙二醇酯（PET），主要用于包装、薄膜和纤维领域，因此越来越受到科学界的关注。 PEF 可以是 100% 生物基的，因为它的两种单体都可以由生物资源生产，并且与 PET 相比具有更优异的性能，例如机械性能和气体阻隔性能。随着 PEF 越来越接近大规模生产并进入塑料市场，应仔细研究其报废管理，以减轻其环境足迹。本综述重点关注与聚合物废物相关的主要场景的最新技术，包括机械和化学回收、堆肥和焚烧。
