Perceiving the benefits from CP application, the factory insisted to maintain the CP team activities and integrate CP in the general management system at place. In order to facilitate CP application, a simple environmental management system has been developed. The factory has also set up environmental policy, whereby it is requested that the environmental protection law and other regulations should be followed strictly, ensuring the sustainable development of the company and reducing waste emission sources. The factory has integrated process management system with the environmental management system, therefore, energy and material consumption is monitored at the same time with the monitoring of pollutant parameters in the waste streams. A sample system and legal procedures are built and applied for environment data collection, checking, classification and data analysis.
CP not only brings about benefits from energy saving, emission minimization, reduced water consumption, but also helps the Company increase production, improve product quality, and prove prestige. The implemented CP options at the Company are a typical case study for enterprises in the sector of casting production in Vietnam./.
