CHEMICAL RECYLING OF PLASTICS USING IONIC LIQUIDS OR DEEP EUTECTIC SOLVENTS
A method for depolymerizing a mixture of plastics is described. The method comprises (a) providing a composition comprising two of more plastics, (b) introducing a solvent comprising an ionic liquid (IL) or deep eutectic solvents (DES) and optionally water to the composition to form a solvent-plastic composition, such as an aqueous solvent-plastic composition, and (c) incubating the solvent-plastic composition for a period of time to produce a depolymerized composition such that at least portions of the two of more plastics are depolymerized into monomers. The produced monomers can be used as a carbon source for microbes to produce bioproducts.
Waste separator scrap oil extraction device and method of producing recyclate using same
Proposed is a waste separator scrap oil extraction device for producing a recyclate from high-density polyethylene (HDPE) scrap, the HDPE being used as a material for a separator of a lithium ion secondary battery, and to a method of producing a recyclate using the same. The waste separator scrap oil extraction device includes: a first extraction means into which pulverized scrap is input, and configured to primarily separate oil from scrap while extruding the input scrap by a pressurization method with a screw; and a secondary extraction means into which the scrap from which the oil is separated by the first extraction means is input, and configured to generate oil vapor by applying heat to the scrap when the scrap is transferred by a screw and secondarily separate remaining oil by vacuum suction of the generated oil vapor.
Method and apparatus for separating waste material
A self-contained material separator system utilizing a vacuum and blower system, a separator assembly, and a collection assembly to separate and process waste material generated from material handling and processing devices. The material separator may further be self-contained and portable to provide flexibility in the use and deployment thereof.

Separation of multi-layered material to facilitate recycling
A method of separating constituent layers from a paper-plastic laminate material includes disposing a sheet of a paper-plastic laminate material on a first surface. The paper-plastic laminate material includes a paper layer on a first side and a plastic layer on a second side. The method also includes moving an abrasive second surface over the paper layer on the first side to contact the paper layer and separate portions of the paper layer from the plastic layer. The method further includes collecting the separated portions of the paper layer and providing the separated portions of the paper layer as input to a paper recycling process, and collecting the plastic layer and providing the plastic layer as input to a plastic recycling process. The method may help increase recycling rates of paper and plastic, reduce raw material harvesting, reduce pollution and habitat destruction, and improve the quality of recycled material.
ENZYMATIC DEGRADATION OF SEMI-CRYSTALLINE POLYMERS AND PLASTIC WASTE CONTAINING SEMI-CRYSTALLINE POLYMERS
The present disclosure is related to systems and methods of enzymatic degradation of crystallizable polymers or copolymers and PC/IPM containing crystallizable polymers or copolymers.
TUBULAR REACTOR FOR SUPERCRITICAL WATER REACTION
The machinery and methods disclosed herein are based on the use of a specialized extruder configured to continuously convey and plasticize/moltenize selected lignocellulosic biomass and/or waste plastic materials into a novel variable volume tubular reactor, wherein the plasticized/moltenized material undergoes reaction with circumferentially injected supercritical waterthereby yielding valuable simple sugar solutions and/or liquid hydrocarbon mixtures (e.g., neodiesel), both of which are key chemical commodity products. The reaction time may be adjusted by changing the reactor volume. The machinery includes four zones: (1) a feedstock conveyance and plasticization/moltenization zone; (2) a steam generation and manifold distribution zone; (3) a central supercritical water reaction zone; and (4) a pressure let-down and reaction product separation zone. The machinery and methods minimize water usagethereby enabling the economic utilization of abundant biomass and waste plastics as viable renewable feedstocks for subsequent conversion into alternative liquid transportation fuels and valuable green-chemical products.
METHOD AND APPARATUS FOR MANUFACTURING A PRODUCT AND USE
The invention relates to a method and an apparatus for manufacturing a product from a starting material. At least one material batch is collected onto a conveyor or into a conveyor from material portions, the mate-rial batch is heated to a desired temperature and/or a desired temperature is maintained in the material batch on the conveyor or in the conveyor, the conveyor is moved to transfer the material batch to a product manufacturing device in which the product is manufactured from the material batch by a shape-giving tool, and the mate-rial batch is measured or weighed, and the material portions are adjusted based on the measurement results. In addition, the invention relates to the use of the method.
