STRATEGIES FOR WASTE AND COST REDUCTION IN PVC PRODUCTION: A CASE STUDY OF THAI CHIN MIN CO., LTD.

Abstract

This article presents management approaches to reducing waste and production costs in the polyvinyl chloride (PVC) manufacturing process by examining the causes of waste generation through relevant concepts and theories, including Lean Manufacturing (LEAN), the ECRS principle, the elimination of the Seven Wastes (7 Wastes), Total Quality Management (TQM), Quality Control (QC), Kaizen, the PDCA cycle, and Lean Six Sigma. Analytical tools such as 7 QC Tools, SWOT Analysis, and the TOWS Matrix are utilized to identify key factors contributing to waste and develop strategies for minimizing inefficiencies in the production process. Implementing the proposed approaches can help maintain waste levels within the standards set by Thai Chin Min Co., Ltd., thereby reducing production costs, improving product quality, and enhancing the organization's competitiveness.
