Metal-free recyclable polyester produced from a biomass-derived compound

Most plastic and polymer materials around are poorly sustainable, as they are petroleum-based, their preparation needs metal catalysis, and they persist in the environment and cannot be effectively recycled. Seeking for true sustainability, American scientists have now prepared a fully recyclable biopolyester from a biofeedstock-based chemical without any metal catalyst involved. As they report in the journal Angewandte Chemie, the polymer is best suited for regular polyester applications, and i
