How to recycle waste PCBs and what you need to know?

PCB boards are widely used in electronic devices. As technology advances, discarded PCBs are increasing and can pose a hazard to the environment and human health if not disposed of properly. Therefore, how to recycle and effectively recycle waste PCBs has become one of the key issues of the green.

Only the metal part of the PCBs has a reuse value, so the non-metal part needs to be separated from the electronic waste, which is a complicate process. However, with the help of PCB Boards recycling machine, this process can be convenient and efficient. How to recycle printed circuit boards? There are three main ways: Heat recovery, Chemical recovery and Physical recovery. They have pros and cons based on how the metal will be recycled. Let's have a look.

1. Heat recovery 

Pros: For this process, it is necessary to heat the PCBs to a high temperature to recover the metals present on the boards. Heat recovery will incinerate the FR-4 but retain the copper.

Cons: You can use this method if you wish, but it will create harmful gases in the air such as lead and dioxin.

2. Chemical recovery

Pros: Here you will use an acid bed to recover the metal from the PCBs.

Cons: The panel is immersed in acid, which destroys the FR-4 again and also creates a large amount of wastewater that must be retreated before it can be disposed of properly. And the cost is much higher due to the need for professional operators and the retreatment of wastewater.

3. Physical recovery

Pros : This process involves shredding, crushing, and separating the metal from the non-metallic components and this method retains all the metallic components.

Cons: While this method has minimal environmental impact, there are still some downsides. Dust produced in the air, if exposed to the air for a long time, may cause respiratory diseases periods. However, our company has a pulse dust removal system to collect ash treatment, and the ash collection effect can reach more than 99.5%.

The above three methods can provide you with a reference. Many countries have begun to adjust their policies to deal with some problems of industrial pollution. For the long-term consideration of the waste PCBs recycling business, the physical PCB boards recycling machine is more economical and environmentally friendly.

Here are a few things you need to consider if you are planning to start a PCBs recycling business, including: regulations and laws, stable supply for waste PCBs, selling market for the metals, a workshop to place the e-waste PCB board recycling machine, purchase a proper e-waste PCB boards recycling machine.

1. The latest regulations and laws

Recycling waste PCB boards may be subject to regulations and laws, depending on the location and type of recycling method used. It is important to research and comply with any applicable regulations and laws. There is a easy way to confirm these information by just research on peers.Our PCB Boards recycling machine has exports to more than 60 countries, and we can provide some information if you need it.

2. Have stable supply for waste PCBs

Actually, PCB boards, as the raw materials of PCB boards recycling business, is easy to collect in life. So in some home appliances dismantling centers, PCBs manufacturing factory and waste collection stations, etc, we can collect adequate PCBs easily. But the raw materials processed by the PCB boards recycling machine on the market are different.

For our company, our PCB boards recycling machine can process raw materials: various waste circuit boards, copper clad laminates, circuit boards, computer boards, TV boards, printed circuit boards, various waste electrical appliances motherboards, and processing waste. You can also visit factory with your raw materials.

3. Find selling market for the metals

The PCBs can be separated metals and non-metals. In general, the metals can be sold in the local market directly. And the price of metals is considerable. But in different locals, the markets may have differences too. So it’s better to research in your local about the product selling market.

4. Have a workshop to place the PCB boards recycling machine

The area of the workshop depends on the size of the PCB Boards recycling machine and the amount of storage materials.The conventional processing capacity of our machine is 100-2000KG/h, depending on your needs. Different processing capacity configurations and prices are different. If you are interested and want to know more details, please contact us. Our experienced sales staff and professional engineers will provide you with a suitable PCB board recycling machine.

5. Purchase PCB board recycling machine, installation and running 

The last preparation is to buy one set suitable PCB board recycling machine, which is the core to start PCBs recycling business. Considering the above three ways, physical method is the best choice. As a manufacturer of physical PCB boards recycling machine, we are also very professional and competitive.

Our PCB boards recycling machine is designed for processing waste PCBs, which is mainly through the process of shredding, crushing, sieving, air separation and electrostatic separation to separate metals from PCBs.The working efficiency is very high. Meanwhile, it has a high separation rate, which can reach to 99%. Besides, it is also a totally environmental friendly machine, because it adopts dry physical separation way to process waste PCBs. During the whole process, it will not generate water, air and toxic chemicals. 

Henan Doing Company is specialized in waste recycling machine more than twelve years, and we have own high qualified engineer team. If you are interested and want to know more information about PCBs recycling business. Please contact us, and we will give you our best support.
