Solid waste that includes a mixture of wet organic material and dry organic material can be are separated using mechanical separation to produce a wet organic stream enriched in wet organics and a dry organic stream enriched in dry organics. The separated wet organic stream and dry organic stream are separately converted to renewable or recyclable products using different conversion techniques particularly suited for the separated wet and dry organic streams.

A method and apparatus to reclaim metals from scrap material such as automobile shredder residue (ASR) that, after separating out light density components, separates out friable material such as rock and glass by crushing and screening operations to generate a high metal content product.

A waste treatment system for separating contaminants including per-fluoroalkyl and poly-fluoroalkyl substances (PFAS) from bulk solid waste (12). A preparation module (9) having a bulk material separator separates oversize material (14) from bulk solid waste (12). A physical separation module (13), located down-stream of the preparation module (9), separates the bulk solid waste (12) based on particle size using physical and/or hydrodynamic and/or density separation techniques. An extraction/chemical separation module (19), located downstream of the physical separation module (13), adds leachate and/or extractant to separate the contaminants from a slurry output from the physical separation module (13), into a fines output and a contaminated water solution. A water circulation system (21) supplies water to the physical separation module (13) and the extraction/chemical separation module (19), the water circulation system including at least one water treatment process, the treated water being recycled and recirculated within the waste treatment system.

Systems and methods for separating materials and recovery of valuable copper from shredded end-of-life vehicles and appliances are disclosed. Shredded matter, or ASR, is sent through a series of sorters before reaching a system that separates out copper bits. The system utilizes a pair of conveyor belts; one for de-watering and removing most of the plastic and glass particles and a second below the first for separating the copper bits. The second conveyor belt has a belt with a particular tooth pattern and material softness, and is set at a slight uphill incline angle. Water is delivered from the top down the slope and the belt successfully transports mostly just copper up and over a top edge to a collection bin. A cascading series of pairs of conveyors may be used to ensure nearly complete recovery of the copper.

A system for processing solid and liquid waste includes a first shale shaker, a second shale shaker, a submersible pump, a centrifugal pump, a first collection tank, a second collection tank, a mud cleaner assembly, a variable frequency drive (VFD) centrifugal solid-liquid separator, and a water clarifying assembly. The first shale shaker is in fluid communication with the second shale shaker through the submersible pump. The second shale shaker is in fluid communication with the centrifugal pump through the first collection tank. The centrifugal pump is in fluid communication with the mud cleaner assembly. The mud cleaner assembly is in fluid communication with the VFD centrifugal solid-liquid separator through the water clarifying assembly. Resultantly, the system discharges a flow of usable water through the VFD centrifugal solid-liquid separator as an initial load of solid and liquid waste is inputted into the first shale shaker.

A waste sorting system (1) comprising a tank (S) for collecting recyclable material (RM) and a sorting unit (U) comprising a first sorting station (10) connected to the tank (S) through a transport device (12) of the recyclable material and a first sorting basin (14) containing a first liquid solution (L1) of given density to separate, according to Archimedes' principle, the recyclable material (RM) into a first material phase (F1) of first selection and a second material phase (F2) of first submersion; the first sorting basin (14) is delimited at the bottom by a first lower collection portion (140), the sorting unit (U) comprising first scraper means (16) associated with the first sorting basin (14) for collecting the first phase (F1) from a free surface of the first liquid solution (L1) and first wash means (18) of this first phase (F1); the first lower collection portion (140) being passed through by a first conveyor (11).
