Described herein are methods of preparing cutin-derived monomers, oligomers, or combinations thereof from cutin-containing plant matter. The methods can include heating the cutin-derived plant matter in a solvent at elevated temperature and pressure. In some preferred embodiments, the methods can be carried out without the use of additional acidic or basic species.

Provided is a resin composition recycler for recycling a resin composition including a resin and an additive. The resin composition recycler includes: an extrusion reactor that hydrolyzes the resin included in the resin composition to obtain a depolymerized product; and a vaporizer that thermally decomposes the depolymerized product to vaporize a monomer, and the extrusion reactor comprises: a first introducer that introduces the resin composition; a second introducer that introduces water; and a screw that mixes the resin composition with the water.

Systems and methods are provided that involve a subcritical water reaction to recycle the cellulose and polyester components of waste cotton and cotton/polyester blend textiles that would otherwise be discarded or disposed of. Specifically, the disclosed methods provide for treatment of the waste textiles to produce advanced materials including cellulose and terephthalic acid (TPA) with a low environmental impact. The cellulose and TPA that are produced are of a high quality allowing for production of regenerated cellulose and regenerated polyethylene terephthalate (PET) suitable for fiber spinning and textile applications.
