摘要： Methods for the recovery of natural fiber-containing material from waste textile and methods for recovery of monomers and/or oligomers from waste plastics comprise contacting about 10 to about 25 wt % of the waste with about 75 to about 95 wt % of an aqueous reagent, the aqueous reagent comprising at least about 80 wt % water and about 20 wt % or less tetraethylene glycol, based on the water and the tetraethylene glycol, and a base, at a temperature of about 90° C. to about 140° C. for about 20 to about 60 minutes to depolymerize polymers in the wastes. The base is included in the aqueous reagent in an amount effective to depolymerize the polymers.
