Composites recycling is gaining traction
Although CW’s coverage of composites recycling dates back over a decade, informal statistics still show that only ~2% of composites-related companies are active recyclers. That said, three years since our most recent feature on the subject, there is demonstrably greater interest and activity, and real applications of recycled fiber are growing.
