Our iron and steel industry has developed rapidly these years, and has always been maintained as the world largest steel producing country since 1996. But the traditional production model (mass production, mass consumption and mass wasting) makes the resources bottleneck and environment issues increasingly prominent, which not only hampers the sustainable development of Chinese iron and steel industry but also brings serious environment problems.In recent years, the recycling economy model has become a hot-spot research field, and also has had successful application in many areas, which is an effective way to achieve the sustainable development, esp. for the iron and steel industry in spite of the lacking of the efficient and perfect reverse logistics system.In this thesis, the author established the reverse logistics models for the iron and steel industry to achieve the recycling economy, through the theoretical research, benefit analysis and case study. First, the basic theory of recycling economy and reverse logistics was analyzed, and then the different reverse logistics models in domestic and foreign steel companies were compared in detail to present the enlightenment for the reverse logistics construction in our iron and steel industry. On the basis, taking the case of B Steel Company, the interaction mechanism between the developing level of recycling economy model and the reverse logistics system were analyzed carefully, which elucidates the necessity of establishing both internal and external reverse logistics system to develop the recycling economy, which were designed later according to its geographical advantage and production solution.Finally, an evaluation model for internal reverse logistics was brought out by financial analysis and cost-benefit analysis methods, which confirmed that the designed model can bring the significant economic benefits and social benefits. Then, taking B Steel Company as an example, a Petri-net based simulation model for external reverse logistics, the eco-industrial zone model, is established to prove the benefits of eco-collaboration rather than the production alone. |
