Techniques recycle plastics in multiple successive process steps. A polymer, preferably a recyclable material, is melted using a discharge extruder, filtered using a first filter device under a positive pressure atmosphere, filtered and degassed using a degassing device, and discharged using a discharge extruder. The degassing device has at least one filter element and a vacuum chamber with a negative pressure atmosphere for filtering and degassing purposes, wherein the plastic melt can be conducted into the negative pressure atmosphere of the vacuum chamber through the filter element.

The present disclosure provides poly(tetrafluoroethylene) (PTFE) microparticles with a Dv50 of about 20 μm to about 30 mm and a specific surface area (SSA) of at least about 3.0 m.sup.2/g when measured by a multipoint BET method of ISO 9277. Such PTFE microparticles can be obtained via a method including thermomechanically degrading scrap PTFE in the presence of air and/or oxygen and reducing the particle size of the resultant degraded PTFE.

A process for forming particles. The process includes a step of entraining gas into a precursor material, wherein the gas includes from about 50 vol % to about 75 vol % carbon dioxide and from about 25 vol % to about 50 vol % other constituents. The precursor material is deposited onto a moving conveyor. The precursor material is cooled to form a plurality of particles.

A powder production method includes providing at least one elongated member including a ductile material; providing a rotating or vibrating cutter configured to repeatedly cut an end of the at least one elongated member to produce particles; and advancing the at least one elongated member or the cutter towards the other of the at least one elongated member or the cutter to cut the particles from the at least one elongated member to produce a powder comprising a plurality of the particles. The particles produced by the method can have a diameter ranging from about 10 μm to about 200 μm.

A method of manufacturing a solid granule for use as or in a cleaning agent includes providing an anionic surfactant component having at least one anionic sulfonate surfactant and at least one anionic fatty alcohol-based sulfate surfactant; providing a granule-forming agent; mixing the anionic surfactant component and the granule-forming agent into a solid mixture; receiving the solid mixture in a granulation device, the granulation device having a first roller cutter and a second roller cutter, the first roller cutter includes a plurality of first blades and a plurality of first grooves, the second roller cutter having a plurality of second blades and a plurality of second grooves; cutting the solid mixture into a rough granule by cooperating the first blades with the second blades; and polishing the rough granule into the solid granule by friction rubbing between the first grooves and the second grooves.

A method of manufacturing a dandelion latex shoe component. Dandelion rubber, CIS polybutadiene rubber (BR), and butadiene styrene rubber (SBR) are mixed together to form a first mixture. The dandelion rubber, CIS polybutadiene rubber (BR), and butadiene styrene rubber (SBR) are mixed at a temperature not less than 60° Celsius and not greater than 80° to form the first mixture. Silicon dioxide is then mixed with the first mixture to form a second mixture. The silicon dioxide is mixed with the first mixture at a temperature not less than 80° Celsius and not greater than 100° Celsius to form the second mixture. The dandelion latex shoe component is then formed from at least the second mixture via a molding process.

A continuous granulation system for obtaining conditioned granules is disclosed. The system comprises a processor configured to produce a continuous flow of granules at an outlet of the processor. The system also comprises a collection chamber positioned downstream from the processor and configured to collect the granules from the outlet. Further, the system comprises an air displacement device coupled to the collection chamber and configured to create a unidirectional flow of air at the outlet in a direction of the granules exiting the processor and away from the outlet. The unidirectional flow of air conditions the granules obtained in the collection chamber. A continuous granulation method and a continuous granule collection system for obtaining the conditioned granules is also disclosed.
