A recycling separator system utilizes at least one, and preferably a series of cutters, which may be contained in sections whereby input is combined with fluid and directed through the cutters, such as in series, and then settled material may be removed through one of traps and sinks as at least a component of a first recycled material while floating material may be removed through float outputs as at least a component of a second recycled material.

Method to separate at least a light fraction comprising low-density plastics having a density lower than water from plastic waste using superheating in water. The method is further based on efficient phase separation between different plastic and at least partial melting of the low-density plastics.

A purification apparatus separates a target substance contained in a mixed sample based on a specific gravity difference. The purification apparatus includes a container that receives the mixed sample and a strainer arranged in the container. The container includes an introduction port to introduce a treatment solution for treatment of the mixed sample into the container and a discharge port to discharge the treatment solution from the container. The strainer is configured to catch the target substance in the treatment solution discharged through the discharge port and to hold the target substance in the container.

The present disclosure provides a cascading density separator for facilitating density-based classification of particulate material. Further, the cascading density separator may include a basin defining an interior channel and comprising a first lateral wall and a second lateral wall, the second lateral wall including an outwardly angled deflection portion at a 45 angle relative of a spiral classifier disposed in the interior channel, the basin. Further, the cascading density separator may include a spiral classifier positioned within the basin and interposed between the first lateral wall and the second lateral wall, the spiral classifier. Further, the cascading density separator may include a spray nozzle mounted, the spray nozzle configured for spraying water into the interior channel and washing a lighter material from the particulate material downward for discharge while enabling the denser material to be retained and lifted by the spiral classifier.
