The role of waste circuit board recycling

The waste circuit board is a mixture of glass fiber reinforced resin and various metals. It is a typical electronic waste. If it is not properly handled and disposed, it will not only cause a large loss of useful resources, but also contains chromium and brominated flame retardants. It can cause serious harm to the environment and human health.

The metal content in the board is as high as 40%, the most is copper, in addition to gold, aluminum, nickel, lead, silicon and other metals, many of which are rare metals. Metal powders such as copper and precious metals that are analyzed from them can be sent to metal smelters as raw materials. There are also non-metallic components such as glass fiber and resin that can be used in the circuit board, and can also be used as a fiber reinforced material or a filler; the waste residue can also be used as a raw material for building materials. These can still be recycled.

The domestic market prospect of copper powder metal is very broad. From the perspective of the development of the domestic market, copper powder is widely used in iron-based copper-based powder metallurgy parts, of which copper-based powder metallurgy parts are the largest. In addition, in the electric carbon industry and in the conductive rubber and copper paste of metallic pigment coatings, the demand for copper powder is also increasing.

How to effectively recycle and recycle electronic waste materials such as waste circuit boards has become a new topic facing China's economic, social and environmental sustainable development and recycling of renewable resources in China. After years of research and practice, our company has launched a new generation of circuit board recycling equipment, which effectively solves the problem of waste of resources, protects the environment, and conforms to the national circular economy and sustainable development policies.
