在航空航天、汽车、可再生能源、核工程和体育等高科技领域，对高性能材料的需求已经变得潜在。欧盟废物管理立法对未来制造业的影响不断扩大，当前废物管理方法的价格不断上涨，强调了高效和可持续地回收复合材料行业产生的废物的重要性。航空航天公司估计，由于制造方式的原因，飞机生产中30%-50%的材料被报废。公司需要支付填埋复合材料的费用，否则这些复合材料可能是一种宝贵的资源。鉴于考察单个生产废物的产量可以最大限度地提高材料的再利用或回收能力，获得关于废旧材料类型的信息可以为开发复合再利用/回收供应链提供信息。本研究侧重于了解在各个复合材料制造过程中产生的废料的规模，以评估其在再利用/回收能力方面的潜在价值。与四家复合材料制造企业进行了基于物流分析的数据采集研讨会。通过案例研究，已经确定有三种与纤维有关的废物产生：干纤维、纤维材料片材下料和咖喱复合材料下料。捕获的信息可用于材料规格的制定。这可以弥合复合材料制造商和废物处理商之间的差距，以解决2009年复合材料战略概述的基础设施不足和废物材料规格障碍的问题。
The necessity of high performance materials has become latent in high technology sectors such as aerospace, automotive, renewable energy, nuclear engineering and sports. The expanding impact on future manufacturing of the EU waste management legislation and increasing price of current waste management methods stress the importance of an efficient and sustainable way of recycling waste generated in the composites industry. Aerospace companies estimated that 30–50% of materials in aircraft production are scrapped due to the way it is manufactured. Companies need to pay for landfilling the composite materials that otherwise can be a valuable resource. In a view that looking at individual production waste outputs could maximise the material reuse or recycling capability, gaining information about the type of scrap materials could inform the development of composite reuse/recycling supply chain. This research paper focuses on understanding the scale of scrap created in individual composites manufacturing processes to assess its potential value in terms of reuse/recycle capabilities. A Material flow analysis based data collection workshop has been performed with four composite manufacturers. Through the case studies it has been identified that there are three fibre related waste outputs captured: dry fibres, fibre material sheet off-cuts, and curried composite off-cuts. The captured information allows for the material specification development. This allows bridging the gap between the manufacturers and the waste processors in composites to address the lack of infrastructure and lack of waste material specification barriers outlined by the Composites Strategy 2009.
