Why recycle waste circuit board?
Waste circuit boards are composed of metals and resin fiber. These metal are usually toxic, but recyclable. So if we throw them away directly, it will not only pollute the environment, but also cause resource waste.

How to recycle waste circuit board?
There are three common processing methods to recycle waste circuit board: mechanical treatment, fire treatment and chemical reagent treatment. Next, I will briefly introduce these three methods.
1.Mechanical treatment

PCB board recycling machine is the most common machine to recycle waste circuit board by mechanical treatment. Just through the process of shredding, crushing, sieving and separating , metals and non-metals will be separated easily. The separation rate can reach to 99%. And it adopts dry type separation method to recycle waste circuit board, which will not use water, fire or chemicals. It is an environmental friendly machine.
2.Fire treatment
Compared to the mechanical treatment, fire treatment is a simple way, which uses fire to burning the non-metals of the waste circuit board, then to get metals. However, this way may damage the quality of metals, and the black smoke generated during processing will not only pollute the environment, but also damage the human health.

3.Chemical reagent treatment
The principle of chemical reagent treatment is similar with fire treatment. It is aimed to melting the non-metals of the waste circuit board to get metals. But this way will also damage the environment and do harm to human health. And some chemical reagent's price of is very high, which is hard to afford to.
These three ways are the most common method to recycle waste circuit board. And mechanical treatment is more and more popular in people in order to protect environment. PCB board recycling machine is the most popular way of mechanical treatment.
