Abstract
Systems and methods involving subcritical water reactions are provided to recycle the cellulose and polyester components in waste cotton and waste cotton / polyester blend textiles that would otherwise be discarded or disposed of. Specifically, the disclosed methods provide for the processing of waste textiles to produce advanced materials with low environmental impact that include cellulose and terephthalic acid (TPA). The cellulose and TPA produced are of high quality and can be used to produce regenerated cellulose and regenerated polyethylene terephthalate (PET) suitable for fiber spinning and textile applications.
