The study emphasizes upon the sustainable way to design an efficient, stable, ecofriendly and recyclable catalyst approach for PET and PC waste glycolysis into value added products. The metal-based catalytic materials promote various mechanisms of glycolysis reaction. The easily produced, extensive, low-priced, green and highly active catalytic materials have been evaluated for the chemical degradation/ recycling of plastic into monomers and valuable chemicals. In this study, the layered double hydroxides (LDHs) composed of different metals ions (M = Zn, Mn, Pb, Cd, Mg, Ni, Co, Ca, Cu) as MAl-CO3 have been synthesized because of the potential applications of these anionic synthetic clay materials with their specific properties including tailored acidic and basic sites, adsorbent-specific behaviour, anion exchangeability, tuneable metal composition, biocompatibility, layered structure and catalytic properties …
