Applying the principles of Six Sigma to environmental management systems

The purpose of this paper is to explore the potential benefits of applying the key principles of Six Sigma to environmental management systems (EMSs). A conceptual framework for the application of Six Sigma to EMSs was developed. The application of the conceptual framework is demonstrated in a case study focused on a major Middle Eastern manufacturing company. The case study showed that there were numerous benefits to applying the principles of Six Sigma to EMSs. An approach based on the conceptual framework was successful in reducing thinner consumption in the case company's paint-mixing room by 37%. Other benefits included cost reductions, less waste to the landfill, decreased amount of waste water, reduction of emissions, reduction of energy consumption and safety improvements. It is anticipated that the results will be of interest to practitioners and researchers in quality and environmental management. Copyright © 2012 Inderscience Enterprises Ltd.
