ZNO-POROUS GRAPHITE COMPOSITES, THEIR USE AND MANUFACTURE

High surface area 3D mesoporous carbon nanocomposites can be derived from Zn dust and PET bottle mixed waste with a high surface area. Simultaneous transformation of Zn metal into ZnO nanoparticles and PET bottle waste to porous carbon materials can be achieved by thermal treatment at preferably 600 to 800 C., and reaction times of from 15 to 60 minutes, after optionally de-aerating the reaction mixtures with N.sub.2 gas. The waste-based carbon materials can have surface areas of 650 to 725 m.sup.2/g, e.g., 684.5 m.sup.2/g and pore size distributions of 12 to 18 nm. The carbon materials may have 3D porous dense layers with a gradient pore structure, which may have enhanced photocatalytic performance for degrading, e.g., organic dyes, such as methylene blue and malachite green. Sustainable methods make ZnO-mesoporous carbon materials from waste for applications including photocatalysis, upcycling mixed waste materials.

CONVERTING RECYCLABLE MATERIALS INTO MANUFACTURING PRODUCTS

A method of processing municipal solid waste includes extracting food waste, inert materials, and ferrous and non-ferrous metals from the municipal solid waste, shredding the municipal solid waste and thereby generating a product feed comprising at least 99.7% by volume cellulose-based materials and plastic. The product feed is conveyed to a forming system and a manufacturing product is created out of the product feed with the forming system.

Device for recycling and recycling waste tires
20200139588 · 2020-05-07 ·

The invention discloses a device for recycling waste tires, which includes a machine body. The upper end of the machine body is provided with an inlet with an upward opening on the right side of the body. The left wall of the inlet is connected with a chute. The chute is provided with A steel wire removal device, a crushing cavity is connected to the lower wall of the inlet, and a crushing device is fixed in the crushing cavity. A twisting cavity is provided in the left wall of the crushing cavity and below the chute. A fourth motor is fixed in the wall, and an eccentric wheel is dynamically connected to the lower end of the fourth motor. The invention can quickly and accurately pull out the steel wire layer in the tire and twist the broken rubber stuck on the steel wire, so that the steel wire and the tire are cleaned. Recyclable materials such as rubber are separated. At the same time, the tires that have been torn out of the steel wire are broken into small pieces of rubber, which is convenient for the next processing, which not only saves the company a lot of material costs, but also saves a lot of time costs and labor.

METHODS FOR MANUFACTURING BULKED CONTINUOUS FILAMENT FROM RECYCLED PET
20200122360 · 2020-04-23 ·

A method of manufacturing bulked continuous carpet filament that includes providing a polymer melt and separating the polymer melt from the extruder into at least eight streams. The multiple streams are exposed to a chamber pressure within a chamber that is below approximately 25 millibars, or another predetermined pressure. The streams are recombined into a single polymer stream. Polymer from the polymer stream is then formed into bulked continuous carpet filament.

RECYCLING OF SMART WINDOWS
20200016641 · 2020-01-16 · ·

The present invention relates to the methods of recycling electrochromic devices and also designing such devices while keeping recyclability in perspective. Recyclability includes recovering of certain materials for re-use within the same application or other applications. Using recycling reduces or eliminates waste stream quantities to be disposed of and/or reduces toxicity of these waste streams.

METHOD FOR PRODUCING AN RPET PLASTIC MATERIAL FOR USE IN A THIN WALL INJECTION MOLDING PROCESS AND HOLLOW BODY PRODUCED IN THE THIN WALL INJECTION MOLDING PROCESS
20240100742 · 2024-03-28 ·

The invention relates to a method in which a starting material for injection-molding, having a viscosity of between 0.50 and 0.7 dL/g, is produced with the aid of a chain breaker from a recycled post-consumer PET having a viscosity of between 0.72 and 0.86 dL/g according to ASTM D4603 and a copolymer fraction of at most approximately 3%. In the method, the comminuted and dried PET material is melted and decontaminated to such a degree that it is suitable for applications in the food sector and the consumer goods sector. A chain breaker is added to the rPET material in the melt of the recycling extruder and/or preferably the melt of the injection unit in order to lower the viscosity and to enrich the PET with copolymers.
