20220136152 · 2022-05-05 ·

Aspects of the present disclosure relate to a nonwoven textile that is sustainable and that sustainably manufactured. The subject matter may be sustainable in one or more respects. For example, the nonwoven textile may be manufactured from recycled materials. In other instances, the nonwoven textile is itself recyclable to produce additional or subsequent nonwoven articles. In addition, the manufacturing processes used to make the nonwoven textile may consume less energy than other manufacturing processes.

DEVICE FOR WHOLLY TREATING URBAN AND RURAL MIXED HOUSEHOLD REFUSE AT LOW TEMPERATURE ON SITE AND USING METHOD THEREOF

A device for wholly treating urban and rural mixed household refuse at low temperature on site is provided. The device includes a vibration sieving and crushing system, a magnetic separator, conveyor belts, a magnetic pulse mineralization reactor and a tail gas purifying device. By using the device, urban and rural mixed household refuse is continuously fed; the mixed household refuse is sieved by the vibrating sieve according to viscosity, weight and size; nonferrous metal is sieved through a magnetic field; and organic substances are conveyed to the magnetic pulse mineralization mixed household refuse treatment device for terminal treatment. So, efficient reduction and harmlessness of the organic substances in the mixed household refuse are realized, and the pollution of organic wastes on the environment is effectively eliminated.

System and process for sorting and recovery of recyclable materials from mixed waste

A system and process for sorting and recovery of recyclable materials, and in particular, sorting and recovery of recyclable materials from mixed waste comprising municipal solid waste in a materials recovery facility.

PROCESS FOR SEPARATING MIXTURES OF SOLIDS
20220118464 · 2022-04-21 ·

The invention pertains to a process for separating mixtures of solids based on their densities. The present invention also relates to the use of a separating liquid (L) for separating plastic solids from metal-containing solids based on their densities, wherein the separating liquid (L) has a density d3 such that 1.5<d3<2.0; wherein the solids have a particle size ranging from 0.1 to 100 mm. The separating liquid (L) is preferably a fluorinated fluid.

Upcycling process for unsorted waste stream
11760859 · 2023-09-19 ·

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.

Recycled glass pozzolan for concrete

An apparatus for producing pozzolanic material from consumer waste includes a glass separator unit to remove glass material from the waste and a size reduction unit downstream the glass separator unit. The glass separator unit includes a tubular outer member and an inner helical member extending inwardly from the inner surface of the tubular outer member and defining an open central bore. The tubular outer member and the open central bore define respective coaxial longitudinal axes that are disposed at an angle relative to a horizontal reference plane, with the inlet higher than the outlet. Non-glass/non-ceramic material is output through the open outlet end of tubular outer member utilizing a flow of water. The glass/ceramic material is output to the size reduction unit through the open inlet end of the tubular outer member utilizing the rotating inner helical member of the glass separator unit.

Gypsum Washer
20220023875 · 2022-01-27 ·

A gypsum washer includes a rotating trommel receiving raw material and a flow of water, and having paddles tilted to reduce impacts of the gypsum passing through the trommel while still providing a washing action. Bentonite separates from the gypsum in the trommel, liquifies, and is released through a mesh screen at the end of the trommel separating from the gypsum. The gypsum is released from the trommel into a water fed trough, scooped from the trough, and released into a storage area. The liquified bentonite is carried by a water flow into one or more settlement tanks, and recovered for use.
