摘要： A method of depolymerizing a polyester in a waste material is disclosed. The method comprises: supplying the waste material comprising the polyester to a depolymerization vessel; depolymerizing the polyester to form a depolymerized mixture comprising a regenerated diol, a regenerated diacid, and a catalyst; isolating the regenerated diacid and the catalyst from the regenerated diol to form a regenerated composition including the regenerated acid and the catalyst; and separating the regenerated composition from the regenerated diol. In addition, a regenerated composition formed from depolymerization of a waste material is disclosed wherein the regenerated composition comprises a regenerated diacid and a catalyst and wherein the catalyst is present in an amount of from 5 ppm to 300 ppm.

摘要： 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.

摘要： A method of forming a polyester from a regenerated composition comprising a regenerated diacid and a catalyst obtained from depolymerization of a polyester in a waste material is disclosed. The method comprises: reacting a diol and the regenerated diacid in the regenerated composition to form one or more compounds including an ester bond; optionally providing additional catalyst; and polymerizing the one or more compounds including an ester bond to form a polyester.

摘要： The presently disclosed subject matter relates to an industrial system for processing various plant materials to produce marketable materials. Particularly, the system integrates subcritical water extraction technology and includes a pre-processing module and a two-stage extractor (processing module) with constant control of temperature, pressure, and/or residence time. In some embodiments, the final product of the disclosed system can include feedstock constituents for biofuel production (sugars and/or oil), biochar, raw materials for various industries (such as pulp for manufacturing paper or cellulose for use in various industries). The disclosed system can be modular or non-modular, stationary or mobile, and can include prefabricated elements with programmed automatic or manual operation so that it can be easily moved and/or assembled on site.

摘要： A method of obtaining a purified regenerated diacid from a depolymerization of a polyester in a waste material wherein the depolymerization provides a depolymerized mixture comprising a regenerated diol, a regenerated diacid, and a catalyst is disclosed. The method comprises: separating a regenerated composition including the regenerated acid and the catalyst from the regenerated diol; providing the regenerated composition in a liquid medium to form a pre-aged mixture; subjecting the pre-aged mixture to thermal cycling wherein the cycling occurs within 25° C. and within a temperature range of from 150° C. or more to 300° C. or less to form an aged mixture; and separating the regenerated composition from the liquid medium in the aged mixture.
