The invention relates to an apparatus for processing solid waste, which comprises a base provided with linear rails (10) on which a carriage (20) moves, said carriage being held on the rails by castors and supported by a hydraulic cylinder; a collection unit arranged at the head end of the rails (10) and provided with an upper opening (30) that receives the waste and transfers it by gravity to a processing unit (40) comprising conical elements (not depicted) in the inner region thereof, and, centrally, a shaft with a helicoid (41) surface, said shaft (41) being rotated by a motor with a motor-reduction unit (42); and an extrusion unit (50) that receives the triturated waste from the collection unit, said extrusion unit (50) comprising a base provided with holes and a conical opening opposite the area of inflow of the waste from the processing unit (40).

Proposed is a waste separator scrap oil extraction device for producing a recyclate from high-density polyethylene (HDPE) scrap, the HDPE being used as a material for a separator of a lithium ion secondary battery, and to a method of producing a recyclate using the same. The waste separator scrap oil extraction device includes: a first extraction means into which pulverized scrap is input, and configured to primarily separate oil from scrap while extruding the input scrap by a pressurization method with a screw; and a secondary extraction means into which the scrap from which the oil is separated by the first extraction means is input, and configured to generate oil vapor by applying heat to the scrap when the scrap is transferred by a screw and secondarily separate remaining oil by vacuum suction of the generated oil vapor.

A dust solidification system includes: a preduster for sucking dust with a negative pressure generated by a negative pressure generating source, removing solidification-inhibiting substances from the dust, and making the dust with a reduced solidification-inhibiting substance content rate flow toward the source; a dust capturing mechanism for capturing the dust flowing from the preduster and allowing the dust to fall; a storage tank for storing the dust captured by and falling from the capturing mechanism; and a dust solidifying mechanism for solidifying the dust in a forming chamber; and further includes one or more of the following: a dust re-scattering prevention mechanism for preventing re-scattering of the dust falling from the capturing mechanism; a stirring mechanism for stirring the dust loaded into the solidifying mechanism; and an air releasing mechanism for preventing air from entering the forming chamber by releasing air flowing into the storage tank from the solidifying mechanism.

The embodiments of the present disclosure provide a centralized treatment device for kitchen waste. The centralized treatment device includes an upper box, an outer cover, a pulverizer, an inner cover, a filter press, a drying granulator, a lower box, an electrolysis device, a hanging basket, a material box, an exhaust fan, and a linkage mechanism. Smashed kitchen waste is subjected to solid-liquid separation by the filter press. Filter residues enter the drying granulator to be partially carbonized, and partially carbonized filter residues and mixed powder treatment agent form solid residue particles. The solid residue particles degrade and adsorb pollutants in the water after being activated by an acidic solution. Meanwhile, accumulated water-absorbing solid residue particles help to degrade the pollutants in the water through the electrolysis device. A separation area is configured to separate oil and discharge the oil separately.

A waste processing system and method for improving compaction and/or separating organics and liquids from waste material. An elongated extrusion screw and/or an adjustable compression gate may be provided to improve the compression of waste material. An improved extraction tube may also be provided to facilitate separation and removal of organics and other liquids from the compressed material. At least one sensor may be provided for sensing an increasing accumulation of waste material awaiting to be processed. An exemplary embodiment may also be adapted to add dry fraction to a waste load that is wet with organics or other liquids to improve compressibility. A system and method may also be adapted to automatically adjust to improve compression of the material and facilitate more efficient production.
