The invention disclosed a method for recycling rare earth elements from waste light-emitting electronic components by pyrolysis and alkaline melting-acid leaching. Based on the pyrolysis properties of the organic polymer, through catalytic pyrolysis of the organic polymer material in electronic components and convert the carbon in the residue into water gas, realize high-efficient dismantling of waste electronic component packaging materials. The traditional problems that the compositions of waste light-emitting electronic components are difficult to disassemble are solved, the generated pyrolysis gas and water gas can continuously supply energy for the pyrolysis system and recover the heat in the flue gas to save energy. Meanwhile, based on the chemical dissolution reaction mechanism of phosphors, the combination process of alkali melting, and acid leaching is used to efficiently recover rare earth elements from the waste light-emitting electronic components, and the step leaching of rare earth elements is realized. The rare earth oxalate can be recovered by precipitation, which greatly reduces the difficulty of late separation and purification.

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.
