An apparatus (2) and a method for pretreatment of organic waste from the Organic Fraction of Municipal Solid Waste and/or from food industries, upstream of an anaerobic digester. The apparatus comprises:—a squeezing-diluting-unpacking module (4) configured to receive an input waste stream (3) of packaged waste and a dilution fluid (10), to lacerate the packaging, and to output a coarser non-digestible stream (23) and a comparatively dirty and comparatively liquid slurry (26),—at least one settling module (30, 30a) configured to allow inerts in the comparatively dirty and comparatively liquid slurry (26) to sediment and to output a finer inerts stream (40) and a comparatively refined slurry (42),—a thickening/dewatering module (60) configured to separate and output a liquid stream (69) and a comparatively dewatered slurry (72).

An automated process for separating and recycling a broad mix of waste material including industrial and commercial streams. The process begins by collecting the broad mix of waste material. Optionally, the broad mix of waste material is sorted to remove contamination from the broad mix of waste material. Next, the broad mix of waste material is coarsely shredded. Plastic film is removed from the broad mix of waste material, creating a stream of plastic film and a separate stream of dirty cardboard. Residual plastic is separated from the cardboard stream and included either in the plastic stream or in an independent third stream. The process yields separate streams of a film-rich recycled plastic and a clean recycled cardboard having a purity of at least about 95%. Also provided are a related system and at least one computer-readable non-transitory storage medium embodying software for performing the process.

A multi-waste processing system includes a processing chamber. The processing chamber includes one or more heaters and a piston, and the processing chamber is configured to evaporate liquid waste and compact solid waste input. A condenser is operably connected to the processing chamber. The condenser is configured to condense water from the evaporated liquid waste output from the processing chamber. A gas and water separator is operably connected to the condenser. The gas and water separator is configured to separate water from the evaporated liquid waste output from the processing chamber. A recirculation pathway connects the gas and water separator to the processing chamber to recirculate gas from the gas and water separator to the processing chamber. The piston is actuated to keep the one or more heaters in close proximity to the solid waste and the liquid waste in the processing chamber.

Embodiments of the present application provide a waste collecting device, which relates to the technical field of lithium cell manufacturing. The waste collecting device includes a frame, a waste buffer box, a negative pressure flow-equalizing box and a waste collecting box. The waste buffer box is arranged in an upper part of the frame and the waste buffer box is provided with a waste pipeline. The negative pressure flow-equalizing box is arranged on the top of the waste buffer box, the negative pressure flow-equalizing box is communicated with the waste buffer box, and the negative pressure flow-equalizing box is provided with a negative pressure pipeline. The waste collecting box is movably arranged in the lower part of the frame and is selectively communicated with the waste buffer box.

There is provided a method for efficiently taking out a metal part coated with a thermosetting resin from an electrical appliance which is no longer needed. Included are a step in which the electrical appliance is exposed to an atmosphere filled with superheated steam to carbonize the thermosetting resin, a step in which an impact is applied to the thermosetting resin which is made fragile by carbonization to cause destruction and a step in which the metal parts are separated from the destroyed thermosetting resin.
