A method of depolymerizing a polyester in a waste material is disclosed. The method comprises: supplying the waste material comprising the polyester to a depolymerization vessel; depolymerizing the polyester to form a depolymerized mixture comprising a regenerated diol, a regenerated diacid, and a catalyst; isolating the regenerated diacid and the catalyst from the regenerated diol to form a regenerated composition including the regenerated acid and the catalyst; and separating the regenerated composition from the regenerated diol. In addition, a regenerated composition formed from depolymerization of a waste material is disclosed wherein the regenerated composition comprises a regenerated diacid and a catalyst and wherein the catalyst is present in an amount of from 5 ppm to 300 ppm.
