China is developing country with the largest population and fastest economy growing in the world but also in short of natural resources. Therefore, it's necessary and significant to raise comprehensive utilization by developing and using recyclable resources. To implement clean production inside factory is to recycle waste material or liquid produced during production and reuse it into production as environmental friendly resources, which create environment-protection yield for enterprise. How to choose advanced recycling and regeneration technique is a symbol of standard of our clean production. With the issue of Clean Production Promotion Regulation, it becomes very significant to set up scientific developing concept and create peace environment for human and nature and realize the target of support wastage by wastage treatment and change wastage into money" for continuous economy development.

With the development of China PCB industry now China over the United States and ranked as the second largest PCB providing country behind Japan in the world. But we are not strong PCB fabricating country. We are not strong enough in R&D of hi-tech PCB and, we are not strong enough in comprehensive management, we are also not strong in environmental pollution treatment. The PCB fabricating process are very complex with a great deal of solution and consume a quantity of metal resources such as gold, silver, copper, so it's looked as serious environment-polluted industry. Therefore, while we are developing our PCB industry, it becomes very significant for our industry to recycle polluted solution and regenerate it and reuse waste water treated and reduce pollution to the environment and change wastage into money. Although the economy is developed, the environment was polluted, such a enterprise is also not worthy to exist.

During our analysis and research, PCB industry is metal-consuming industry. 50-60% copper on CCL will be etched and changed to waste etching solution. However, the volume of waste etching solution is the biggest among all waste solution produced during PCB production so it's worthiest to recycle and it's resource but not waste liquid. It will help you in recycling copper from waste liquid to set up one set of PCB copper waste liquid recycling and treatment equipment. Reusing the regenerated solution into production will not only create environment production economy but also increase your income in order to realize the target of support wastage by wastage treatment" and reasonable regeneration of wastage as well as encouraging clean production.
