Provided is a method for delaminating a composite by immersing the composite into a delamination solution; wherein the composite comprises a metal substrate and a coating applied on one side or both sides of the metal substrate, wherein the coating comprises a polymeric binder; and wherein the polymeric binder comprises an aqueous copolymer. The use of delamination solution comprising a strong base allows for complete delamination of the composite in a highly efficient and extremely fast manner. Furthermore, the delamination method disclosed herein circumvents complex separation processes, contamination and corrosion of the metal substrate and enables an excellent materials recovery. An application of the method for delaminating an electrode for a battery is disclosed herein.

Processes and facilities for using one or more PET-containing materials as a feedstock to a chemical recycling facility, and in particular a solvolysis facility, are provided herein. The PET-containing materials used as feedstock may comprise a quantity of PET and metal-containing reclaimer co-product. The PET and metal-containing reclaimer co-product may comprise a quantity of plastic articles, plastic flakes, and/or plastic fines, and may be derived from plastic reclaimer separation processes such as eddy current separators. Such metal-containing co-products are generally undesirable or unusable to mechanical PET recycling facilities, and typically are sent to landfills and/or incinerators. However, the processes and facilities described herein make use of the PET and other plastics present in these otherwise undesirable or unusable metal-containing co-products.

An organic waste recycling apparatus comprises: a catalyst for making the carbonization of an organic waste targeted for waste disposal; a UV irradiation member for irradiating UV at a wavelength capable of breaking a bond in a molecule constituting the organic waste; a processed object housing member whereof the interior space houses the catalyst; a heating member provided in the interior space; and a stirring member provided in the interior space. The organic waste is one that has undergone crushing into small pieces. The processed object housing member is such that the catalyst and the organic waste that has been UV-irradiated by the UV irradiation member and introduced into the interior space are in contact with one another and stirrable in this state by the stirring member.

An alloy treatment method is provided, in which a solution containing nickel and/or cobalt is obtained from an alloy containing nickel and/or cobalt and also containing copper and zinc, the method comprising: a leaching step for subjecting the alloy to a leaching treatment with an acid under the condition where a sulfating agent is present to produce a leachate; a reduction step for subjecting the leachate to a reduction treatment using a reducing agent to produce a reduced solution; an oxidation/neutralization step for adding an oxidizing agent and a neutralizing agent to the reduced solution to produce a neutralized solution containing nickel and/or cobalt and also containing zinc; and a solvent extraction step for subjecting the neutralized solution to a solvent extraction procedure using an acidic phosphorus compound-based extractant to produce a solution containing nickel and/or cobalt.

A waste management system for plastic or other material floating on the surface and in the subsurface of a body of water. A shredding device will reduce the size of the particles of waste. Ocean water is removed by a drying device. The dried waste material is frozen to a temperature at or below minus fifty degrees Fahrenheit, using liquid nitrogen or other suitable means. The frozen waste material is then pulverized and ground into a powder. The powder may then be sprayed into a gas-filled chamber and heated. Temperature, pressure and humidity are maintained within the chamber for more than one minute. Microwave or other radiation and catalysts may be used to enhance the process of extraction. The processed material is then removed from the chamber. Carbon may be recycled or used as fuel by the ship. Water may be used by the ship or returned to the ocean.

A reagent system for treating heavy metal-contaminated materials is provided and includes an oxidizer, a soluble phosphate, and an alkaline hydroxide source, such as a caustic soda or lime. A method of treating mine waste bearing one or more heavy metals is also provided and includes the step of admixing a reagent system with heavy metal-containing material to preferentially reduce the leachability of heavy metals and form precipitates and complexes of low metal solubility that remain stable within the host solid matrix for long durations in acidic and abrasive conditions.

A catalyst is illustrated, which has 70-90 parts by weight of mica, 1-10 parts by weight of zeolite, 5-15 parts by weight of titanium dioxide, 1-10 parts by weight of aluminum oxide, 1-5 parts by weight of sodium oxide and 1-5 parts by weight of potassium oxide. The present disclosure also illustrates a pyrolysis device using the catalyst, and further illustrates a pyrolysis method using the catalyst and/or the pyrolysis device for thermally cracking an organic polymer.

Superabsorbent fiber (SAF) in a feed stream is converted into soluble polymers in an extensional flow device. The total energy used to degrade the SAF into soluble polymers is less than about 50 MJ/kg SAF.
