Abstract
Pre-treating a waste polyester material with dichloromethane (DCM) produce purified polyester for reuse. The purified polyester can be recycled via any chemical or mechanical recycling process. Where the waste polyester material includes non-polyester contaminants, the DCM-treated polyester material produces a slurry that includes the DCM, a solid component that includes a polyester monomer product for reuse, and a waste liquid component where the non-polyester contaminants can be filtered from the top of the liquid component.
