In this study, two Mn-doped ZnO powders were preparedby mechanical milling, using MnOx and ZnO obtained from therecycling of spent alkaline batteries. The prepared materialswere evaluated as catalysts in the glycolysis reaction of PETand the catalytic activity was associated with the optical andstructural properties of the samples. Also, the reaction product‘s quality, BHET, was evaluated by different techniques. Thenovelty of this work is the use of metal oxides recovered fromspent batteries as a catalyst in the glycolysis process of PET. Inthis way we propose the treatment and recovery of two highlypolluting residues for the environment, batteries and plasticbottles
