Since the implementary of cleaner production audit, the company proposed many cleaner production programs. And the company fully carried out the programs with no expense, low expense, medium expense and high expense by auditing and improving side by side, then achieved win-win of economic and environmental benefits. For now the program was recognized by the Environmental Protection Bureau of Shandong Province and Weifang Economic and Information Technology Committee. And the company was awarded Class A certificate for the cleaner production audit performance issued by the Environmental Protection Bureau of Shandong Province, and got “Excellent” level during the cleaner production audit organized by Weifang Economic and Information Technology Committee.
