One object is to efficiently secure good quality oil by preventing the clogging of tar in a device body or piping. There is provided a waste plastic liquefaction device comprising a pyrolysis tank that thermally decomposes and gasifies a waste plastics; a gas cooler that cools a pyrolysis gas generated in the pyrolysis tank to produce a generated oil; and a circulation tank that recovers the generated oil produced by the gas cooler and circulates a portion of the generated oil to the gas cooler. The circulation tank has a temperature adjustment device which maintains the temperature of the generated oil in the circulation tank within a predetermined temperature range in the circulation tank. The circulation tank is connected to a centrifugal separator so that the generated oil in the circulation tank is returned to the circulation tank after impurities is removed by the centrifugal separator.

A separation apparatus is disclosed, comprising: a layerizer arranged to bring a group of particles in a layer on a transport surface with a constant spatial relation of the particles relative to each other in the layer; an identifier arranged to identify particles in the group of particles that have a specific property; a separator arranged to separate the particles in the group based on a difference in affinity between the particles and the separator; an affinity modifier arranged to modify said affinity for identified particles relative to non-identified particles in the group. The layerizer comprises a recirculating transport surface on which the particles of the layer are carried. The transport surface is arranged to move along a transport trajectory as a rigid plane. Further, a method for separation of particles from a group of particles is disclosed.

A method for sterilizing and decontaminating post-consumer absorbent sanitary products contaminated by organic compounds deriving from human metabolism and comprising drug residue, said post-consumer absorbent sanitary products comprising fractions of plastic, super-absorbent polymers (SAPs), and optionally cellulose, the method comprising at least the steps of: i) sterilizing (SR) said post-consumer absorbent sanitary products by heating to a temperature equal to or lower than 140° C. and at a pressure comprised between 1 bar and 3.6 bar to obtain sterilized post-consumer absorbent sanitary products; and ii) decontaminating (DC) from organic compounds said sterilized post-consumer absorbent sanitary products by means of an oxidizing treatment. The oxidizing treatment is carried out by putting the sterilized post-consumer absorbent sanitary products in contact with a gas containing ozone preferably at a temperature equal to or higher than 60° C., more preferably comprised between 60° C. and 80° C. The sterilized post-consumer absorbent sanitary products subjected to the decontaminating step have a humidity of less than 80%, preferably comprised between 60% and 75%.

A method of producing a chemical pulp from a textile material which comprises cellulose for manufacturing regenerated cellulosic molded bodies, wherein in the method the textile material is comminuted, at least a part of non-fiber-constituents of the comminuted textile material is separated from fiber-constituents of the comminuted textile material, at least a part of non-cellulosic fibers of the fiber-constituents is mechanically separated from cellulosic fibers of the fiber-constituents, at least a further part of the non-cellulosic fibers is chemically separated from the cellulosic fibers, and producing regenerated molded bodies from the chemical pulp based on the cellulosic fibers after mechanically separating and chemically separating.

Methods and equipment for the recycling of carpet are disclosed that produce a clean fiber product suitable for industrial use. The methods allow the recovery of face fiber material, for example a polyester, polyolefin, or a polyamide, from carpets that includes a face fiber material, a polypropylene backing material, and an adhesive, and include the steps of mechanically impacting the carpet to break the bonds between the adhesive and the fibrous components, treating the fibrous components to remove adhesive granules from the fibrous components, and optionally separating the polypropylene backing from the face fiber. A clean adhesive/calcium carbonate product can also be produced from this process.

A method for sterilizing and decontaminating post-consumer absorbent products polluted with organic compounds derived from human metabolism including drug residues, the post-consumer absorbent sanitary products comprising fractions of plastic, super-absorbent polymers (SAP), and optionally cellulose, the method including at least the steps of: sterilizing (SR) the absorbent sanitary post-consumer products by heating to a temperature equal to or less than 140° C., and to a pressure lower than 4 bar, decontaminating (DC) the post-consumer absorbent sanitary products of organic compounds by treating with an oxidizing composition comprising at least one compound selected from the group consisting of hydrogen peroxide, sodium percarbonate, potassium percarbonate, sodium perborate, potassium perborate, potassium monopersulfate, ammonium persulfate, sodium persulfate, potassium persulfate, and ozone. The at least one compound is contained in the oxidizing composition in an amount equal to or greater than 2% by weight with respect to the dry weight of the post-consumer absorbent sanitary products.

The invention discloses a safe, cost effective, portable, eco-friendly sanitary pads disposing device and system. The device is smart and automatic used for shredding and disinfecting the used sanitary pads without any environmental pollution. The system comprises of plurality of collection bins, sanitary pad disposal device, a data acquisition module, a remote server, a data transmission module etc. for remotely monitoring the status of each disposal process.

There are provided processes for recycling waste such as polystyrene thermoplastic polymer waste and/or polystyrene thermoplastic copolymer waste as well as recycled polystyrene thermoplastic polymer and/or recycled thermoplastic copolymer that may, for example, be obtained from such processes. The processes can comprise dissolving the waste in cymene, xylene or ethylbenzene or a suitable solvent, to obtain a mixture followed by heating the mixture under acidic conditions and then optionally neutral conditions in the presence of a reducing agent then cooling to obtain a supernatant comprising polystyrene thermoplastic polymer and/or polystyrene thermoplastic copolymer and a solid waste residue. The supernatant can optionally be treated with a filtration aid, then the supernatant can be contacted with a hydrocarbon polystyrene non-solvent under conditions to obtain precipitated polystyrene thermoplastic polymer and/or precipitated polystyrene thermoplastic copolymer which can be washed with additional hydrocarbon polystyrene non-solvent, and optionally dried and formed into polystyrene thermoplastic polymer pellets and/or polystyrene thermoplastic copolymer pellets.

The subject matter proposes an automated compact depackaging system. The depackaging system includes a receiving hopper, a vertical depackager, dumpsters and a sedimentation unit. The vertical depackager simultaneously removes and cleans packaging materials and the materials that exit the system are clean and organics free. The system also includes a dosing device for dosed discharge of waste or bulk material into the hopper. The hopper may also receive the organic wastes directly from trucks. The dosing device is fitted with metal to identify metals in the bulk material. The assembly includes a grabber on an overhead crane to pick up the metal piece once located. The hopper comprises air doors and air roofs to keep off from smell spreading into the room. The organics that are extracted from the waste are free of plastics and other packaging material.
