Cleaning and separating medical waste
11260437 · 2022-03-01 ·

The present invention comprises a method of shredding treated medical waste, cleaning it of all traces of biological gunk, and sorting it into separate components for recycling. To clean biological gunk from materials, all materials must be first shredded into small parts to expose the interior. The cleaning is performed by submerging the gunk coated materials into a caustic solution that breaks down and dissolves the gunk off of the materials. The caustic solution may comprise sodium hydroxide, potassium hydroxide, or a similar chemical, which is highly effective in producing a corrosive chemical that can break down blood, bone marrow, urine, unused medication, food waste, organs, tissues and any other biologic materials. After all of the biological material is removed from the cleaned materials, they are sorted into component materials, such as plastics, metals, rubbers, glass, etc.

CRUSHING METHOD FOR GALVANIC CELLS WITH HIGH ENERGY DENSITIES
20220056553 · 2022-02-24 ·

A crushing method for galvanic cells with high energy densities in which mixture of used cells is placed inside an insulated container and carbon dioxide as dry ice is added to this mixture as a cooling medium. Dry ice is added to the mixture of used galvanic cells at a volumetric ration of 0.5:1 to 2:1. The mixture of used cells with dry ice is cooled down from −20° C. to −50° C. and is subsequently fed to the crushing device and subjected to crushing. A stream of used galvanic cells and a stream of dry ice granules are preferably fed simultaneously to the insulated container of the crushing device, and this mixture is forwarded to the working part of the crushing device. At the end of galvanic cell crushing, the mixture of air and gaseous carbon dioxide is returned to the insulated container.

Method for recycling indium

Provided is a method for recycling indium from a panel on which an electrode layer made of indium tin oxide (ITO) is formed, comprising: S1 —removing each of pattern layers on the panel to obtain particles formed by the pattern layers; S2 —adding an acid solution to the particles so as to dissolve the substances which can be dissolved in the acid solution, and then filtering to give a solution containing indium ion; S3 —adding an alkaline solution to the solution obtained in step S2, so that metal ions other than indium ion can form precipitates with hydroxyl ion; S4 —filtering off the precipitates formed in step S3; and S5 —evaporating the solution obtained in step S4 to obtain crystals of indium salt. The method improves the reusing rate of the defective panels, is helpful to environment protection, and saves resources.
