Upcycling process for unsorted waste stream
10954354 · 2021-03-23 ·

A dynamic process for upcycling polymers. Polymers from a diverse post-consumer waste stream are gathered in a mixture. The mixture is extruded and combined with a liquid additive containing a particular PE wax at the verge of polymerization. The liquid additive is repolymerized into LDPE to form pellets. The pellets are delivered into a reactor and submerged in a suitable solvent to dissolve the LDPE. Causing a gradual and orderly separation of the remaining polymers from one another, resulting in a layered substrate. The suitable solvent, enzymes or depolymerizing compatible chemical is delivered into the reactor through independent pipes attached to tanks containing the suitable depolymerizing agent. The process repeats depolymerizing the layered substrate layer by layer with additional suitable solvents/enzymes or depolymerizing agents for each of the polymers resulting in the dissolving of the remaining polymers in an orderly manner producing a layered wax-like material for upcycling.
