According to experts, the waste printed circuit board contains a lot of toxic and harmful substances, and it is extremely difficult to recycle. As an electronics information industry cluster, Wuxi produces a large amount of “electronic waste†every year, including about 10,000 tons of waste printed circuit boards. In the past, such special garbage was generally treated by washing, incineration, etc., and it was easy to cause secondary pollution.
The physical recycling technology and equipment for waste printed circuit boards that have passed the appraisal have been developed by Chinese scientific and technological personnel for three years. They have complete independent intellectual property rights and have obtained national patents. This technology is currently in trial operation at Wuxi Wanrong Technology Co., Ltd., which can digest 5,000 tons of waste printed circuit boards every year.
According to reports, in the automated assembly line, the waste printed circuit board is pulverized and separated, and the precious metals are recycled. The non-metallic materials are made into profile plates, industrial backing plates, chairs and chairs in the scenic area. According to preliminary estimates by experts, 5,000 tons of "electronic waste" can create an annual output value of more than 50 million yuan after this "reborn", truly achieving a win-win situation of economic and social benefits.
