    Abstract: A process for depolymerizing a polymer comprises reacting the polymer with a nitrogen-containing compound in the presence of a catalyst whereby the polymer is depolymerized into one or more monomers. The catalyst comprises carbonate and an element in group 1 or group 2 of the periodic table. The nitrogen-containing compound comprises ammonia, an amine reagent, or a combination of ammonia and an amine reagent. The polymer comprises polyamide, polyester, polycarbonate, polyurethane, polybutylene terephthalate (PBT), polyethylene terephthalate (PET), lignocellulosic material, or combinations thereof.
