Abstract
The chemical recycling of poly(ethylene terephtalate) PET using a unconventional method employing microwave radiation was studied. The reaction parameters were varied in order to study their influence. The reactivity of several glycols was compared and results showed consistency with conventional solvolysis methods. The dissolution of PET polymer into the glycol solution is one of the key parameters in determining the reaction time. The modification of the microwave field power afforded a 50% reduction of the reaction time. This method presents certain advantages compared to conventional glycolysis methods such as: energy and time saving through a rapid and a more uniform heating capacity, leading to a complete depolymerization in the presence of the catalyst.
