Global warming has revealed public awareness of environmental protection and motivated customers to request green products. Pressures can also create opportunities. As the enterprises face the fact and take a corrective action, those who best meet and find solutions to the challenge will lead the competitive pack. Given this trend, this paper presents a green strategy for building a green manufacturing model that connects production system and life cycle assessment required and injects green thinking into each stage of manufacturing process. This model drives original manufacturing system from a less green into a greener and more eco-efficient manufacturing. From the result of this case study, the model is an attempt to better explain green manufacturing and is no doubt a shot in the arm for companies to develop sustainable competitiveness.
