According to incomplete statistics, more than 550,000 tons of waste electronic circuit products purchased and partially smuggled from all over the country are dismantled and processed every year (1 million tons were dismantled annually during the peak period from 1997 to 1999). , motors, computers, and household appliances are more than 400,000 tons, and circuit boards are more than 150,000 tons, and they are increasing every year. Similar phenomena exist in other coastal areas and areas where circuit board production is concentrated. During the process of separating and recycling the metal components of waste circuit boards, non-metallic material waste accounts for nearly 50-80% of its mass, which has become a difficult problem for electronic waste treatment. In order to solve this problem, Guowang Environmental Protection: developed "waste circuit board powder extrusion molding equipment" and "waste circuit board powder profile extrusion equipment" to solve the problem that has been plagued for many years.
