Першы, check this video. Then you can get a preliminary understanding of the current situation of e-waste……

Electronic waste, commonly known as e-waste, has received increasing attention in recent years for its far-reaching social, environmental and economic impacts. With the rapid development of electronic devices and consumers constantly upgrading their electronic products, the amount of e-waste generated has surged.
E-waste announced by the European Commission includes discarded electronic and electrical equipment. This type of waste includes a variety of technological products that have exceeded their service life or are inefficient. Electronic devices contain harmful elements and, unlike ordinary garbage generated in cities, they pose a major threat to ecosystems and human health.
Many countries, especially developing countries, lack the infrastructure to properly handle and recycle e-waste, leading to environmental and health risks caused by improper e-waste disposal. Currently, many people use dangerous methods such as open burning, landfilling, open dumping, Нефармальнае дэмантаж і ручная перапрацоўка. Гэтыя практыкі ўяўляюць істотны рызыка для аховы здароўя. Каб пазбегнуць высокай кошту належнага ўтылізацыі, Многія развітыя краіны выбіраюць экспартаваць электронныя адходы ў такія краіны, як Індыя і Афрыка. У цяперашні час гэтыя краіны змагаюцца з праблемай недастатковай інфраструктуры для кіравання электроннымі адходамі.

Літый батарэі

Таму што літый батарэі ўтрымліваюць шмат матэрыялаў для шматразовага выкарыстання:
Літый: Літый з'яўляецца ключавым кампанентам літый -батарэй, і перапрацаваная літый можна выкарыстоўваць для вырабу новых літый -батарэй. Напрыклад, у электрамабілях і партатыўных электронных прыладах, Перапрацоўка і паўторнае выкарыстанне літыя мае важнае значэнне для зніжэння выдаткаў на сыравіну і забеспячэння пастаўкі літый -рэсурсаў.
Кобальт: Many lithium batteries contain cobalt in the positive electrode materials, such as lithium cobalt oxide (LiCoO₂). Cobalt is a rare and expensive metal, and recycled cobalt can be reused in the battery manufacturing industry, reducing dependence on newly mined cobalt resources.
Nickel: Some lithium batteries (such as nickel-cobalt-manganese oxide (NCM) batteries) contain nickel. The recycling of nickel helps to recycle resources, and in the production of new batteries, recycled nickel can meet some of the raw material needs.
Copper and aluminum: Copper and aluminum are usually used in the casing and electrode connection parts of lithium batteries. These metals can be purified through recycling processes and then reused in electronic equipment manufacturing or other industrial uses.

Recycling methods:
Lithium batteries recycling production line Includes steps such as disassembly, crushing and screening. Першы, disassemble the waste lithium battery, separate the shell, electrode and other parts, then crush the electrode material, and separate copper, aluminum and other metals by screening and magnetic separation.

Circuit board

Recycled materials:
Precious metals: Circuit boards contain precious metals such as gold, silver, and platinum. Gold is mainly used for pins, contacts and connection parts of some high-precision electronic components on circuit boards because it has good conductivity and corrosion resistance. Silver is often used in circuit boards and some components such as capacitors. These precious metals have high recycling value and can be reused in industries such as electronic component manufacturing or jewelry.
Non-ferrous metals: Copper is the most important non-ferrous metal in circuit boards and is used to make circuits and connecting wires of various electronic components. Recycled copper can be used to make new wires, cables and electronic components. У дадатак, circuit boards also contain a small amount of tin, which is mainly used for welding electronic components. The recycled tin can be used again in the production of welding materials.
Rare metals: Such as tantalum, which is used in some high-performance capacitors on circuit boards. The recycling of tantalum helps meet part of the demand for rare metals in the electronics industry because tantalum resources are relatively scarce.

Circuit board recycling method:
Першы, disassemble the circuit board to remove large components, and then break the circuit board into small particles. Then use physical sorting methods such as gravity sorting, magnetic separation and electrostatic sorting to separate different metals and non-metallic materials.

Solar panels

Recyclable materials:
Silicon: Silicon is the main material of photovoltaic panels, especially in crystalline silicon photovoltaic panels. Recycled silicon can be reused in photovoltaic panel manufacturing after purification and other processes, or used in other semiconductor-related industries.
Silver: The electrode part of photovoltaic panels usually contains silver, які выкарыстоўваецца для збору і правядзення бягучага. Перапрацаванае срэбра можна выкарыстоўваць для вырабу новых фотаэлектрычных электродаў або праводных частак іншых электронных прылад.
Алюміній: Каркас фотаэлектрычных панэляў звычайна вырабляецца з алюмінія, і перапрацаваны алюміній можна выкарыстоўваць для вырабу новых фотаэлектрычных рамак панэлі альбо іншых алюмініевых прадуктаў.
Шкло: Панэль фотаэлектрычных панэляў у асноўным зроблена са шкла. Перапрацаванае шкло можна выкарыстоўваць у такіх галінах, як архітэктурнае шкло і аўтамабільнае шкло пасля чысткі і апрацоўкі.

Як Перапрацаваць адходы сонечнай панэлі:
Першы, Выкарыстоўвайце выдаленне кадра, каб разбіраць фотаэлектрычную панэль і асобныя кампаненты, такія як шкло, Алюмініевая рамка і акумулятарныя клеткі. Пасля выдалення шклянкі, Фотаэлектрычная панэль раздушана драбнілкай. The silicon wafers separated from the battery cells are first crushed and ground into smaller particles or powders, and then screened using screening equipment to filter out silicon, copper, and EVA glue.
