A growing interest in the conversion and utilization of biomass, coupled with rapid developments in the biorefinery industry, has introduced a wide spectrum of opportunities in the production of novel monomers and polymers from renewable sources . However, questions persist about the selection of the best and most selective catalyst. Conventionally, PET material is produced in melt processes using antimony-based catalysts in the form of oxide or acetate, known for their high performance and ability to withstand elevated temperatures. Nevertheless, a significant drawback arises from the presence of residual metals within the polymeric material, which is challenging to remove due to strong metal-ester interactions. This can lead to material discoloration and raise environmental concerns upon disposal, potentially disqualifying the polymer's use in various applications, including the medical industry .
