Abstract: A method for separating and recovering plastics from a waste stream including size separating the waste material, comminuting the material, and separating material at a specific density between 1.0 and 1.1 SG. Systems are included herein. PP and PE are separated from the waste stream.

Abstract: A fluidized inertia table for separating materials between an upstream delivery station and a downstream receiving station is provided. The fluidized inertia table for separating materials creates a moment of inertia and/or rotary motion which are then translated into reciprocating or jarring motions and separates the materials loaded onto the tray.

Abstract: A method for preparing clean aggregate from a waste stream including sizing the incinerator combined ash to recover a first material; wet screening the first material with a first screen to recover the material of disparate sizes; and processing each of the groups.

Abstract: Systems and methods can sort materials of different specific gravities in a mixture. These systems and methods for separation of materials provide multiple forces simultaneously. The system can utilizes both vertical and the horizontal forces for efficient separation of materials with different specific gravities.

Abstract: A system for recovering of metal and sand from incinerator ash material having an ash clarification assembly, a magnet to remove the ferrous from the heavy material; a sorting assembly, a drying cage or dewatering unit to dry the material; and a separation assembly to remove the aluminium from the material. Methods are included as well.

Abstract: This application discloses a separator for separating and recovering materials from a waste stream. The separator has a cyclone having a top section and a bottom section, an impeller within the cyclone, a media inlet for accepting a flow of media or a pulsating flow of the media operatively connected to the impeller in which media or fluid flows through the impeller into the separator; a first discharge passage for a collecting a light fraction, and a second discharge passage for collecting a heavy fraction.

Abstract: A cyclonic separation and materials processing method and system is presented in which materials entry at one end and which is arranged so that the materials that enter will be given a tangential velocity component as they enter. Specific embodiments include a three-dimensional sorting system with the use of an outward centrifugal motion and up/down (or vertical) motion flow of water or other media, which can be thought of as “a three-dimensional separation”.

Abstract: Devices, systems, and methods for separating waste stream with high glass concentrations to recover desired materials are described. The devices, systems, and methods may include a wet separator, a multi-stage screen(s), shredder(s), rising velocity separator(s)/jig(s), magnetic pulley(s), eddy current separator(s), and/or optical sorters.

Abstract: A method for recovering metals from waste in which material is roughly or coarsely separated to leave a fibrous feedstock, the feedstock is comminuted with a mill (e.g., a ball mill) to liberate and separate the fibrous feedstock to obtain a mix of a metal fraction and residue, and the metals fraction and the residue are collected. There is a system employing the same to treat such materials.

Abstract: A fluidized inertia table for separating materials between an upstream delivery station and a downstream receiving station is provided. The fluidized inertia table for separating materials creates a moment of inertia and/or rotary motion which are then translated into reciprocating or jarring motions and separates the materials loaded onto the tray.

Abstract: An apparatus/system for separating a mixture of solid materials has a screening bed, an expansion chamber in gaseous communication with the screening bed, a filter in gaseous communication with the expansion chamber, an air flow producer in fluid communication with the filter. The screening bed includes a star-shaped agitators and the air flow is a vacuum from the screening bed through pathway.

Abstract: Devices, systems, and methods for separating incinerator combined ash are described. The devices, systems, and methods include a fines process that utilizes water or other liquid in the separation of portions of the incinerator combined ash.

Abstract: A system and method for recovering metals from electronic scrap and auto shred residue (ASR) are described. Electronic scrap and ASR materials initially undergo size reduction processes. The reduced materials are thereafter separated according to size and magnetic properties to remove ferrous materials from the processing stream. Non-magnetic materials remaining in the processing stream are separated using oxygen encapsulated separators. The oxygen encapsulated separators strategically encounter materials to generate waste, a precious metals concentrate, and a metal concentrate.

Abstract: This application describes method and systems for recovering metals from metal-containing material. Some embodiments of the disclosed method include one or more of the following three steps: (1) sizing, (2) separating using the helix separator, and (3) collecting. A system can execute these steps.

Abstract: A system multiple having units in a linear arrangement employs density separation processes. In one arrangement, the system provides more control over the agitation and forces separating the material. One system has a paddlewheel 115, 215 in some or all of the units to create movement to optimize the residence time (faster or slower) to optimize separation.
