风能被广泛部署,在减少世界对化石燃料的依赖方面发挥着关键作用。第一代风力涡轮机现在即将结束其使用寿命,并且对于风力涡轮机叶片中的复合材料的再利用或再循环存在有限的选择。风力涡轮机叶片由热固性聚合物基质中的玻璃或玻璃和碳纤维沿着包括聚合物泡沫和轻木的芯材料组成。复合材料的性质和风力叶片的硬壳式构造使得分离材料和部件以供再利用是高度能量密集的。大多数退役的风力叶片要么被填埋,要么被焚烧,因为这些过程的成本很低。本文报告了一个新的案例研究,以再制造退役的风力涡轮机叶片和重新部署的叶片作为高压输电线结构的主要承载元件。本研究的重点是开发一个信息框架的材料,环境和成本分析,成功地重新利用退役的建筑元素。该框架利用材料流分析来评估流程每个阶段所用材料的数量及其对环境和成本的影响。
Wind energy is widely deployed and plays a key role in reducing the world’s dependency on fossil fuels. The first generation of wind turbines is now coming to the end of their service lives, and there are limited options for the reuse or recycling of the composite materials in the wind turbine blades. Wind turbine blades are composed of glass or glass and carbon fibers in a thermosetting polymer matrix, along with core materials including polymer foams and balsa. The nature of the composite materials and the monocoque construction of wind blades make it highly energy intensive to separate the materials and the parts for reuse. Most decommissioned wind blades are either landfilled or incinerated, due to the low cost of these processes. This paper reports on a novel case study to remanufacture decommissioned wind turbine blades and redeploy the blades as the primary load-carrying elements for high-voltage electrical transmission line structures. This research focuses on the development of an information framework for the material, environmental, and cost analyses for the successful repurposing of decommissioned construction elements. The framework utilizes material flow analysis to assess the amount of material used at each stage of the process and its environmental and cost implications.
