Can the timely disposal of waste circuit boards reduce environmental pollution?

Timely disposal of waste circuit boards reduces environmental pollution

With economic development and technological progress, the number of discarded circuit board products has been on a linear upward trend. On the one hand, it causes great harm to the environment, and on the other hand, it wastes precious resources, especially precious metals. This situation has attracted great attention from governments, environmentalists and business circles around the world. Some countries and regions have taken effective measures and done a lot of work in laws and regulations, recycling systems and recycling technology research and development.

1. The incineration method is to first crush the circuit board waste to a certain particle size, send it to a primary incinerator for incineration, and decompose the organic components in it, so as to separate the gas from the solid. The residue after incineration is bare metal or its oxide and glass fiber, which can be recovered by physical and chemical methods after crushing. Gases containing organic components enter the secondary incinerator for combustion and discharge.

Second, pyrolysis is also called dry distillation in industry. The circuit board waste is placed in a container and heated under the condition of isolating the air, so that the organic substances in it are decomposed and converted into oil and gas, which can be recovered after condensation and collection. As the solid residue in the device, it can be separated and recovered by simple physical methods. Different from the incineration of electronic waste, the vacuum pyrolysis process is carried out in the absence of oxygen, so the production of dioxins and furans can be suppressed, and the amount of waste gas produced is small, which pollutes the environment.

3. The basic principle of chemical treatment method is to utilize the difference of chemical stability of various components in circuit boards to recycle waste printed circuit boards . This method is a process in which various metals are gradually refined and recovered through multi-stage chemical reactions by liquid-forming metal-rich bodies or circuit boards after crushing.

As an indispensable and important component of electronic products, circuit boards are widely used in various electronic devices. In order to solve the problem of secondary pollution caused by the crushing of waste circuit boards, it is necessary to solve it in time.
