Environmental Policy

Nevertheless, PCB production always involves chemical processes, and therefore the company continuously invests in its waste water treatment and recycling facilities.

Sung Wei has been honoured by the Shenzhen government as “Gardening Company”, a Green Company, and an Outstanding Waste Reduction Enterprise. We have also been recognized by the Guangdong provincial government as a Saving Enterprise, by the PCB industry as a Green Advanced Enterprise, and by Sony as a Green Partner.
