Non-limiting embodiments of the present disclosure relate to a method comprising: obtaining asphalt shingle waste (ASW) and performing grinding, screening, and separating steps on the ASW. In some embodiments, granules are removed from the ASW. In some embodiments, the method transforms ASW into ASW powder. In some embodiments, the ASW powder is formed into a plurality of briquettes. In some embodiments, at least one of: the ASW powder, the plurality of briquettes, or any combination thereof is fed into a mixing process that results in an ASW powder filled coating.

Methods, systems, and apparatus for winnowing. In one aspect, a method includes loading an initial material into a winnowing system via a feed member; feeding the material into a fluidically accelerated winnowing cavity, where the initial material impacts at least one plate member to yield chaff material and processed material, and where the processed material and the chaff material circulate in the winnowing cavity; and separating the chaff material and the processed from the winnowing cavity based on density. Other aspects include yielding intermediate material, where the intermediate material reimpacts the at least one plate member until yielding chaff material and processed material, preprocessing the initial material, controlling the flow of initial material into the winnowing cavity with a feed gate, where the chaff material egresses the winnowing cavity via a chaff chute, where the chaff material collects in a collection cavity, and/or more.

A system for refining waste and other mixed material streams including a receptacle for receiving an input stream and a drill separating material from the input stream and outputting a processed stream. An incinerator incinerating the processed stream and outputting an incinerated stream. A mill grinding the incinerated stream and outputting a milled stream. A screen having screen holes filtering the milled stream and outputting a screened stream having particle sizes smaller than the screen holes. A mesh having holes smaller than the screen holes filtering the screened stream and outputting a meshed stream. A magnetic device removing magnetic particles from the meshed stream outputting a non-magnetic stream. A density separator receiving the non-magnetic stream and outputting a first output, a second output having a greater density than the first output, and a third output having a greater density than the second output.

A regeneration treatment method of waste shell-mold and a system thereof are provided. The regeneration treatment method has a raw smashing step, a smashed-particle sieving step smashed-particle, a first magnetic separation step, a grinding step, a second magnetic separation step, a dry pneumatic flotation step, and a vibration sieving step in sequence to obtain a regenerated shell-mold sand. The refined shell-mold sand is obtained from the smashed-particle sieving step. Silica binders of the refined shell-mold sand is effectively removed by the grinding step. Furthermore, particle sizes of the regenerated shell-mold sand fall in a suitable range in the grinding step. Magnetic metals mixed in the waste shell-mold are effectively removed by the first and second magnetic separation steps. Non-magnetic impurity are further removed by the dry pneumatic flotation step. Therefore, the regenerated shell-mold sand are suitable to substitute original shell-mold sand.

A carpet recycling method is disclosed. In a toroidal flow pulper, pieces of carpet are disintegrated in a quantity of liquid to form a slurry of fibrous carpet materials and carpet ash. At least a portion of the fibrous carpet materials are separated from the slurry, and the separated fibrous carpet materials are dried. At least a portion of the carpet ash is isolated from the slurry, and the isolated carpet ash is dried. Thus, a first output comprising dried separated fibrous carpet materials is produced, and a second output comprising dried carpet ash is produced.

Methods for producing a purified wheat embryo product are disclosed. In one embodiment, producing a purified wheat embryo product includes the steps of: accelerating a plurality of wheat berries toward an impact surface, impacting each of the plurality of wheat berries against the impact surface, dislodging at least some of the wheat embryos from the wheat berries in response to the impacting step such that the dislodged embryos are intact, and separating the dislodged wheat embryos from the bran and the endosperm to produce an intermediate purified wheat embryo product.

A system and method for processing an artificial turf, and a product produced by the method, is provided. The method includes providing an artificial turf having an infill, separating at least a portion of the infill from the artificial turf, downsizing the artificial turf into artificial turf fragments and rotationally mixing and translating, by a melt system, the artificial turf fragments at a pressure less than a maximum predefined pressure to form a melt. The maximum predefined pressure is between about 0.08-20 bar.

A system and method for freezing and breaking down tires or other materials is disclosed. The system and method for freezing and breaking down tires includes using a shredder to shred the tires, using a filter to screen the tire shreds, using a water sprayer to rinse the tire shreds, using a freezing tunnel to freeze the tire shreds before they are crushed into tire grains, using a magnet to remove any metallic fibers, filtering out any oversized tire grains for re-freezing and re-crushing, and using a separator to separate out any oversized or undersized pieces before bagging the final tire grains for re-use and recycling.

Ore rock is disintegrated into extremely fine rock fraction in a slurry by subjecting the slurry in selective orders of application of excitation forces and energy to cause spontaneous cavitation to occur in the slurry. The excitation forces and energy are provided by electrodynamic discharges, hydrostatic force, hydrodynamic energy, and sonic vibrations.

A combination grinder and filling apparatus for plant material used to deposit small particles of plant material into a pre-formed cone. The apparatus includes a rotating end cap mounted over a grinder body. Formed on the grinder body is a filling cavity in which bulk plant material is placed. Formed in the end cap or grinder body are knives that cut the plant material when the end cap is placed on the grinder body and rotated. Located under the grinder body is a collection plate with holes that allow small particles to fall into a conical-shaped receiving cavity formed on a connection body. Attached to the collection body is a lower end cap with a lower bore in which the lower neck of the collection body extends. Pressing arms located on the lower end cap automatically press against a pre-rolled cone extended around the lower neck. A plunger extends through the apparatus to pack mall plant material into the pre-rolled cone. An agitator coupled to the plunger is positioned in the receiving cavity and used to break away small plant particles.
