As illustrated by Vestas' V236 - 15 MW turbine, the driving economics of wind turbines have led to gigantic blades made of high-performance materials such as thermosets glass and carbon fibre reinforced polymers (FRP). However, there currently exists no viable process to recycle thermoset FRP blades without degradation of material properties. Hence, blades often end their life in landfills or are incinerated; undesirable scenarios resulting in significant Environmental Impacts (EIs) and loss of material capital [1]. This issue is further exacerbated by the fact that the manufacture of carbon fibres is energy intensive and has substantial Global Warming Potential (GWP ), i.e. more than 10 times that of glass [2]. This lack of sustainability and circularity is a thorny problem which the wind industry and academia are trying to solve using thermoplastic and vitrimer resins to enable, in theory, fully recyclable blades [1]. Even if promising, these technologies are still in development and many technical and practical questions remain regarding, for instance, the quality of the recyclate; how to separate complex blades into their constituents; and the EIs of these recycling processes. More importantly, replacing one resin system by another doesn't fundamentally alter the wind turbine design and its scaling laws, meaning that blades will continue to require extensive amounts of carbon fibre and other raw materials.

如Vestas的V236-15兆瓦涡轮机所示，风力涡轮机的驾驶经济性导致了由高性能材料（例如热固件玻璃和碳纤维增强聚合物（FRP））制成的巨大叶片。但是，目前尚无可行的过程来回收热固性FRP叶片，而不会降解材料特性。因此，刀片经常在垃圾填埋场结束生命或被焚化；不良情况导致了重大的环境影响（EIS）和材料资本的损失[1]。碳纤维的生产是能源密集型的，并且具有巨大的全球变暖潜力（GWP），即玻璃的10倍以上[2]，这一事实进一步加剧了这个问题。缺乏可持续性和循环性是一个棘手的问题，风力行业和学术界试图使用热塑性和玻璃二聚体树脂来解决，从理论上讲，可以完全可回收叶片[1]。即使有希望，这些技术仍在开发中，例如，关于循环系统的质量，仍然存在许多技术和实际问题。如何将复杂的叶片分离成其选民；以及这些回收过程的EIS。更重要的是，将一个树脂系统替换为另一个树脂系统并不会从根本上改变风力涡轮机的设计及其缩放定律，这意味着叶片将继续需要大量的碳纤维和其他原材料。
