The invention relates to devices for disposal of solid and/or liquid waste, in particular, to devices for disposing waste by ionic-electronic destruction method. The invention is directed to broadening a range of reactors for treatment of waste, the reactors having an enlarged area of formation of corona discharge streamers, thus avoiding a need to use a source of high-voltage pulses. The technical effect is attained by a reactor implemented as a closed cavity with an input opening connected to a waste feed unit, and with an output opening for removing gaseous destruction products, where an additional input opening is provided in the closed cavity for supplying electrically charged substance particles into the reactor.

The present invention relates to a chemical and biological integrated degradation process for PET, for recycling PET, and, more specifically, the present invention provides a PET upcycling technique for producing a high-value product via a chemical pretreatment process of PET, a TPA and EG production process using an enzyme, and a process for converting TPA and EG to PCA and GLA, respectively.

A process for recovering silver from a mass of scrap of photovoltaic cells. The process includes steps of: providing the scrap of photovoltaic cells, each including a silicon wafer on the upper surface of which an anti-reflective layer and silver lines are provided; immersing the scrap in water or in an aqueous solution; applying ultrasound to cause the silver to detach; sieving the solution to remove the coarse solid fraction containing the silicon wafer residue; and separating the fine solid fraction containing the silver from the solution.

The present invention provides a method and apparatus for dewatering a biological solid material employing both microwave irradiation and solvent extraction. The method comprises microwave irradiation pretreatment, solvent extraction dewatering, solid-liquid separation, and solvent recovery. Through microwave irradiation of an aqueous biological solid material, gaps in the solid material are increased, and the biological material is fractured, thus releasing more bound water in the solid material. Subsequently, the microwave-irradiated biological solid material is brought into full contact with an organic solvent, allowing the solvent to absorb and extract moisture from the solid, thus removing moisture from the solid. The aqueous solvent is then subjected to evaporation under reduced pressure or gasification under reduced pressure in a separation apparatus so as to separate the moisture and the solvent. The solvent is then compressed, condensed and recovered for recycling. Also provided is a device for implementing the dewatering method.

A hygienic disposal device for sanitary waste includes a supporting structure frame for mounting one or more components, including an opening lid hingedly connected to a hopper equipped with spray nozzles for disinfectant solution and water spraying. A shredder is connected to the hopper for shredding the waste, followed by a mixing chamber for homogenously mixing shredded waste with water. Valves at the bottom of the mixing chamber separate cellulose and plastic waste. Two rotating drums dewater and dry the separated waste, while a dryer blows hot air for further drying. An outlet discharges separated water into municipal sewage lines.
