Thermoplastic carbon fiber bike frames promise a cleaner alternative to conventional carbon fiber. The polymer binder can be melted down and separated from the carbon at end of life, allowing the material to be reused for new frames or other products. Focus Bikes developed a thermoplastic eMTB with a Belgian manufacturing partner, but the project was shelved after Rein4ced filed for bankruptcy. The material has other advantages beyond recyclability. It does not need cold storage like uncured carbon, manufacturing can be highly automated, and producing the frame in Europe shortens the supply chain. The tradeoffs are real too: the machinery is expensive, recycled material degrades over time, and the process still needs energy. The article is worth reading if you want a grounded look at whether recyclable carbon bikes are actually close to production.
