Abstract

Carbon fibre reinforced polymers (CFRP) are very important structural materials due to their mechanical properties, light weight, and versatility. This has led to an increase in both CFRP demand and production. This situation implies an increased number of end-of-life products requiring a viable and environmentally friendly way out. Within this context, this work evaluates the eco-efficiency of a company’s own CFRP recycling system based on a combination of shredding, pyrolysis and solvolysis processes. The eco-efficiency assessment involves techno-economic and environmental analyses of both recycled carbon fibre from the aforementioned system and, for benchmarking purposes, conventional carbon fibre from polyacrylonitrile. The results show a levelised cost of 4.83 € and a carbon footprint of 22.7 kg CO₂ eq per kilogramme of recycled carbon fibre. Furthermore, factor-X results indicate an eco-efficient performance of the assessed recycled carbon fibre compared to conventional carbon fibre.

再生碳纤维的生态效率评估和基准测试

碳纤维增强聚合物（CFRP）具有机械性能好、重量轻、通用性强等优点，是一种非常重要的结构材料。这导致了CFRP需求和产量的增加。这种情况意味着越来越多的报废产品需要一个可行的和环境友好的出路。在此背景下，本工作评估了一家公司自己的基于粉碎、热解和溶剂分解工艺的CFRP回收系统的生态效率。生态效率评估包括对上述系统回收的碳纤维进行技术经济和环境分析，以及为基准目的对聚丙烯腈制成的传统碳纤维进行分析。结果显示，每公斤再生碳纤维的平均成本为4.83欧元，碳足迹为22.7千克二氧化碳当量。此外，因子x结果表明，与传统碳纤维相比，评估的再生碳纤维具有生态效率。
