On Building a Push-Pull Supply Chain of Iron and Steel Scrap

The reuse of iron and steel scrap has high economic value as well as ecological benefits. By analyzing existing process of iron and steel scrap recycling, this paper studied the internal and external conflicts that blocked the smooth going of iron and steel scrap recycling process from the perspective of supply chain. To coordinate these conflicts, a push-pull iron and steel scrap supply chain was built to recover iron and steel scrap resources as more as possible in purpose of environmental protection by "push" strategy and match mallet demand by "pull" strategy. The results indicate that push-pull supply chain is an effective mode that well fit into economic demand as well as environmental demand in iron and steel scrap recycling process.
