Ai-Carbon Co., Ltd. is named after the initials of Advanced Innovative Carbon, and aims to contribute to various carbon material fields from a business perspective. An urgent issue that has emerged is the recycling of carbon fibers, which is rapidly expanding in the market. We aim to isolate and recover carbon fibers from carbon fiber reinforced plastics (CFRP), which are difficult to decompose and pose waste disposal problems, using an inexpensive electrolysis method for reuse.
