How many recycling methods for waste printed circuit boards?

At present, there are three main methods for recycling methods for waste printed circuit boards, such as incineration, acid bubble corrosion, or mechanical method. But the mechanical method PCB recycling machine is the most welcomed method.

Incineration is the first method recycling methods for waste printed circuit boards. Burning plastic and resin contained in waste circuit board to get metal residue. The harmful gas generated by this method will pollute the environment and even seriously affect human health, and burning waste circuit boards will damage the performance of the metal and cause waste of resources.

Burnning waste circuit board will produce lot of secondary pollution

The second recycling method for waste printed circuit boards is use chemical raw materials to dispose waste circuit board, that is to dissolve acid in a strongly acidic aqueous medium and leaching metal components in electronic circuits to achieve the purpose of recovering metals. This method has low treatment efficiency and high cost. There are many problems, and the waste water generated during the operation will be a difficult problem.

The third recycling method for waste printed circuit boards is use physical method for recycling. Waste circuit boards are mechanically pulverized with PCB circuit board recycling machine, and then metal and non-metals can be recycled through air separation and electrostatic separation. This physical separation method is called dry physical separation, and the entire production process does not produce any waste gas and waste residue. This environmentally friendly and pollution-free equipment is called circuit board recycling equipment.

After reading this article, we can see the physical separation method is the best recycling method for waste printed circuit board and PCB recycling machine is the best choice to recycle waste citcuit board.
