Development of Carbon Fibers material recycling technology
TEIJIN LIMITED
Outline
Emissions of process waste and used waste at business sites that manufacture or use carbon fiber-based composites materials and intermediate materials such as prepregs are expected to increase rapidly from FY2020, and reach about three times or more of the current levels in FY2030.
Therefore, in order to realize a society in which carbon fibers that contribute to significant improvements in fuel efficiency in the mobility field and utilization of natural energy such as wind power generation are more easily available and make sustainable growth possible, develop the technology to extract and reuse carbon fibers from the waste described above.
Teijin has been engaged in Carbon Fibers recycling technology development association activities (2012-2014), etc. Based on the technical results obtained here, we proceed with developing our unique quality control / test evaluation technology and application development technology.
Description
Development targets:
Aim to start supplying samples of recycled Carbon Fibers products from around 2025. Amount of CO2 generated when Carbon Fibers is regenerated from Carbon Fibers Composites material is about 1 / 5 that of virgin Carbon Fibers production.
Technical problems:
・Waste identification management
(Identify and sort waste that can be recycled together and waste that should be separated).
・Energy saving / labor saving Carbon Fibers recycling technology
・Set quality inspection items specific to recycled Carbon Fibers products and develop testing methods.
