Carbon fiber-reinforced plastics (CFRP) are used for structural materials in the aircraft and automotive industries due to their lightweight and high strength characteristics. Up until now, Japanese companies have been considered as superior to others in this field because they have sophisticated technologies for the development of high-quality virgin carbon fiber (CF). However, in recent years, especially in the general industry, there has been a demand for inexpensive products that places more importance on price than on quality. Under such circumstances, though the disposal of CFRP is difficult, the recycling business is still virtually unestablished especially in Japan and waste CFRP has been mostly landfilled. Concerns about the effects of CF (dust/milled) on human health and ecosystems also gradually increase. As a result of the organizational issues associated with the commercialization of CFRP recycling technology in the Japanese industrial landscape, it is important to scientifically elucidate the anxiety of the effects of CF (dust/milled) generated during industrial processes including recycling on people and ecosystems before using CFRP recycled products on an industrial scale and distribute appropriate information, confirmed on scientific grounds, so that even ordinary citizens can feel safe and secure with the cyclic use of CF.

碳纤维增强塑料（CFRP）的重量轻，强度高，因此被用于飞机和汽车行业的结构材料。迄今为止，由于日本公司拥有用于开发高质量原始碳纤维（CF）的先进技术，因此它们被认为在该领域中处于领先地位。但是，近年来，特别是在一般工业中，需要廉价的产品，其价格比质量更重要。在这种情况下，尽管很难处理CFRP，但是回收业务实际上仍未建立，尤其是在日本，而CFRP的废弃物大多被掩埋了。对CF（粉尘/碾磨粉）对人类健康和生态系统影响的担忧也逐渐增加。
