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 its monomer component is totally recovered upon heating at tall temperatures.
