Printed circuit boards (PCBs) is the common piece of electric or electronic equipment that is present in almost all electronic devices including computer, laptop, calculator & remote control units, etc. PCB contains a huge amount of metals, polymers, and ceramics and is manufactured by sophisticated technologies.
Typically, circuit boards contain 30% plastic, 30% inert oxide, and 40% metal. Metal recovery is the primary method of recycling waste circuit boards. About 20% of the metal is copper, 8% iron, 2% nickel, 4% tin, 2% zinc, 0.1% gold, 0.2% silver, and 0.005% palladium.
Ways of Recycling Profitably
PCBs can be recycled using equipment for separating metals from non-metals in circuit boards, copper-clad boards, and trim. There are two formal ways of recycling:
One of the common ways is to dismantle electronic components. Firstly, recycle the components and clean the motherboards separately. For some valuable components, such as CPUs, RAMs, and Memory Chips, further extraction is conducted to recover gold/silver and other precious metals. After crushing and separating pure copper and resin powder collected from clean motherboards.
Crush the circuit boards directly without separating the electronic components. After crushing, the waste circuit boards will be pulverized into a mixture of metal and resin fiber. In the end, a high-voltage electrostatic separator will separate the metal from the resin. Metal and non-metal can then be sold directly for reuse after separation.
Benefits of Recycling Waste Circuit Board
- Recycling yields more precious metals than mining: Compared to mined ores, circuit boards can contain 30-40 times more copper and 40-800 times more gold. Therefore, circuit boards represent a more valuable source of precious metals than mining underground. High-performance circuit boards (military, telecom services), as well as older circuit boards, may contain even more precious metals.
- Circuit board recycling is cheaper than mining metals: Gold, copper, and silver are found in circuit boards. Extracting metals from circuit boards takes a lot less money, time, and effort than mining materials from the ground. By recycling this e-waste properly, it can be used to produce other electronics as secondary raw materials.
- Air and water pollution can be reduced by recycling circuit boards: Apart from containing valuable metals, e-waste also contains toxic substances like lead, mercury, and cadmium found in circuit boards and batteries. Recycling is one of the best ways to prevent these toxic substances from polluting our environment.
JR Recycling Solutions Ltd Efficiently and Profitably Recycle Waste PCB
All types of electronic and electric materials are recycled at JR Recycling Solutions Ltd’s fully-equipped recycling warehouse. Their expert team recycles all types of printed circuit boards. In the whole process of recycling waste circuit boards, the waste circuit boards are dismantled, shredded, crushed, and separated. The PCB dismantling machine can separate the boards and electronic components. The shredder and crusher crush the circuit boards into small particles, which will make it easy for the separating
After that, recovered metals were supplied to other industries as secondary raw materials for manufacturing. However, glass fiber can be used as a raw material or a filler for glass fiber processing, thereby achieving the purpose of recycling all resources.
