Abstract: Catalytic compositions for depolymerizing polyolefin-based waste material into useful petrochemical products and methods of use are described. The catalytic compositions are mixed metal oxides demonstrating equal or higher conversion than noncatalytic pyrolysis. These mixed metal oxide catalysts and a polyolefin-based material are heated in the presence of oxygen to form a product comprising one or more olefin monomers.
