Solvent based approach to post-consumer recycling of polyethylene terephthalate

A process is provided of treating a feed comprising polyethylene terephthalate comprising dissolving said feed in a polar solvent at a temperature between about 100 to 250° C. to produce a dissolved feed; then adding an anti-solvent that is less polar than said polar solvent followed by cooling a resulting mixture resulting in precipitation of purified polyethylene terephthalate and then separation of solid purified polyethylene terephthalate from remaining liquids.

USE OF MIXTURES OF WATER AND ESSENTIAL OIL FOR SEPARATING MULTILAYERED COMPOSITES FOR THE SEGREGATED RECYCLING OF POLYMER/METAL FILMS

The invention relates to the use of mixtures of water and essential oils selected from the group consisting of phenols, phenylpropanoids and furanocoumarins, for separating multilayered composites for the segregated recycling of polymer/metal films.

METHOD FOR COMPOSITE DELAMINATION
20230138359 · 2023-05-04 ·

Provided is a method for delaminating a composite by immersing the composite into a delamination solution; wherein the composite comprises a substrate and a coating applied on one side or both sides of the substrate comprising a polymeric binder; and wherein the polymeric binder comprises a copolymer comprising a structural unit derived from an acid group-containing monomer. The use of weak acid-containing delamination solution allows for complete delamination of the composite in a highly efficient manner. Furthermore, the delamination method disclosed herein circumvents complex separation process, contamination and corrosion of substrate and enables an excellent materials recovery. An application of the method for delaminating an electrode for a battery is also disclosed.
