The HolyGrail 2.0 Initiative aims to improve the sorting of plastic waste. But the method also has certain drawbacks. Here, luminescent pigments provide an alternative.

Marker masterbatches enable different information to be embedded in plastics. This can be used to improve the recycling circle.

Closed-Loop Recycling System for Carbon Fiber

Asahi Kasei, Kitakyushu College and Tokyo University of Science have developed a new technology for recycling carbon fiber plastic compounds.

Asahi Kasei has developed an electrolyzed sulfuric acid solution method for recycling carbon fiber plastic compounds together with the National Institute of Technology, Kitakyushu College and Tokyo University of Science.

Carbon fiber-reinforced plastics (CFRP) are highly attractive for various industries in demanding application fields due to their unique balance of rigidity, mechanical strength and light weight – also compared with conventional glass fiber reinforced plastics. However, CFRPs are expensive and challenging from a recycling perspective, as it is difficult to extract the carbon fibers from the resin after usage.

Together with its project partners at the National Institute of Technology at Kitakyushu College and the Tokyo University of Science, Asahi Kasei has developed a recycling method that allows carbon fibers to be extracted from CFRP or carbon fiber-reinforced thermoplastics (CFRTP) used in automobiles. This results in high-quality, inexpensive continuous carbon fiber that can be recycled perpetually, contributing to circular economy.

Electrolyzed Sulfuric Acid Solution Method

Asahi Kasei has developed an electrolyzed sulfuric acid solution method that allows the carbon fiber to retain its original strength and continuous nature while fully decomposing the resin the carbon fiber is embedded in. This allows for its continued use in high-performance applications and presents an inexpensive, circular solution to the end-of-life dilemma of carbon fiber plastic compounds. Thus, these carbon fiber compounds present in vehicles for weight reduction. As stated in a press release, it can be easily and inexpensively be broken down at end-of-vehicle-life and reapplied to new vehicles in the future.

In addition, Asahi Kasei is developing a carbon fiber-reinforced thermoplastic unidirectional tape (CFRTP-UD tape) that utilizes both recycled continuous carbon fiber and the company’s Leona polyamide resin. Boasting a higher strength than metal, this CFRTP-UD tape can be applied to automobile frames and bodies, further enabling the recycling of end-of-vehicle-life parts into different, new automobile parts. According to Asahi Kasei, this presents a solution to the long-term challenge that carbon fiber usage for vehicles has posed on the industry and is expected to economically benefit and strengthen carbon fiber’s usage within the automobile industry on a global scale.
