Pyrolysis of Discarded Chewing Gum for Acetic Acid Recovery
Abstract
Chewing gum, typically discarded indiscriminately, is a significant source of urban solid waste with waste that persist for long period. When in contact with notoriously recyclable materials, it can hinder their recycling processes due to its high post-consumer adhesion, leaving only the non-soluble phase. This gum base is commonly composed of polyvinyl acetate (PVAc). In this context, considering what is done for the recycling of other polymers, the pyrolysis of discarded chewing gum was conduc [...]
