The present invention relates generally to methods for the preparation of nickel-based alloys using waste materials, and more particularly to the preparation of nickel-based alloys using spent batteries.

A brick fabricated from a waste fiber-reinforced polymer (FRP) includes a main body. The main body is formed of a composite. The composition of the composite includes, in parts by weight, 1.0 part by weight of a plurality of furnace slag powders, 0.35 to 0.5 parts by weight of a plurality of glass fiber/polymer particles, 0.02 to 0.5 parts by weight of a plurality of glass powders, and 0.65 to 0.75 parts by weight of an alkali solution. The glass fibers/polymer particles are obtained by crushing the waste FRP. The glass powders are obtained by crushing a waste glass. The furnace slag powders, the glass fiber/polymer particles, the glass powders and the alkali solution are uniformly mixed into a mixture. The mixture is poured into a mold, and then generates a polymerization reaction to form the main body.

Provided herein are composite materials comprising at least 70 wt. % thermally consolidated recovered paper and plastic fragments and less than 5,000 ng water-soluble endotoxin per gram of composite materials, as well as methods of preparing said composite materials and methods of sanitizing recovered waste materials.

The invention relates to a method and system for the elimination of odours in recycled plastic materials, which comprises the steps of: separating and conditioning the plastic; shredding the plastic by means of a bladed shredded, which reduces the plastic into powder-sized particles; chemically washing with a surfactant, which is carried out in a stirring tank; rinsing the plastic material to eliminate dirt and the chemicals used, which is carried out in a rinsing reactor; mechanically drying the clean material in a dryer; and deodorising the plastic, wherein volatile organic compounds (VOCs) are removed from the clean, dry material by means of steam distillation, deodorisation being performed in a steam distillation column, the VOC-free plastic exiting through the bottom part of the column.

Disclosed is a method for preparing aromatic hydrocarbons by hydrocracking a polymer containing aromatic rings, which includes reacting the polymer fragment with hydrogen under the action of a catalyst at a temperature of no more than 350° C.; separating a reaction product to obtain the aromatic hydrocarbons. The catalyst comprises a carrier and an active ingredient supported on the carrier, the active ingredient is at least one selected from Ru, Rh, Pt, Pd, Fe, Ni, Cu and Co, the carrier is at least one selected from metal oxide, phosphate, molecular sieve, SiO.sub.2 and sulfonated carbon, the metal oxide is at least one selected from Al.sub.2O.sub.3, Nb.sub.2O.sub.5, Nb.sub.2O.sub.5—Al.sub.2O.sub.3, Nb.sub.2O.sub.5—SiO.sub.2, TiO.sub.2, ZrO.sub.2, CeO.sub.2 and MoO.sub.3; the phosphate is at least one selected from NbOPO.sub.4 and ZrOPO.sub.4; and the molecule sieve is at least one selected from Nb-SBA-15, Nafion, H-ZSM-5, H-Beta and H-Y.

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.

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.
