Establishing recycling and recovery infrastructures for innovative materials like high-performance composites is very challenging. For such materials, recycling and recovery infrastructures are not yet established, research on end-of-life treatment technologies is still in the development state, and secondary markets for recycled materials are still missing. Against this background, we provide an ex-ante analysis on the design of future cost-minimal recycling and recovery infrastructures for glass (GFRP) and carbon (CFRP) fiber reinforced plastic waste from rotor blades of wind power plants based on a mathematical optimization model. We present insights into future capacities and technologies for the recycling and recovery infrastructures within the EU-28. We systematically analyze the impacts of political regulations and of secondary markets on the design of these infrastructures. While future recycling of CFRP mainly depends on the development of secondary markets independent of political regulations, GFRP is mainly combusted in incineration plants or co-processed in cement clinker plants. Hence, political decision makers should focus on providing measures that support the development of secondary markets for recycled carbon fibers and provide incentives for co-processing of GFRP to overcome capacity limitations.
建立创新材料(如高性能复合材料)的回收和再利用基础设施极具挑战性。对于这些材料而言,回收和再利用基础设施尚未建立,关于报废处理技术的研究仍处于发展阶段,而且再生材料的二手市场也尚未形成。有鉴于此,我们基于数学优化模型,针对风力发电涡轮机能效玻璃纤维增强塑料(GFRP)和碳纤维增强塑料(CFRP)废料的未来成本最低的回收和再利用基础设施的设计,提供了一项预先分析。我们展示了在欧盟 28 国(EU-28)范围内,回收和再利用基础设施的未来容量和技术。我们系统地分析了政治法规和二手市场对这些基础设施设计的影响。尽管未来 CFRP 的回收主要依赖于独立于政治法规的二手市场的发展,但 GFRP 主要在焚烧厂进行燃烧或在水泥熟料厂进行共处理。因此,政策制定者应重点关注为再生碳纤维的发展提供支持措施,并鼓励 GFRP 的共处理,以克服容量限制。
