Under the circumstances of low-carbon economy, the theoretical applications of the green supply chain management of steel and iron manufacture are to reform and innovate the present manufacturing process, enhance the controlling and reclaiming, and recycling using of the waste steel and iron, steel slag, and dust emissions, establish the green supply chain structure oriented to the cycle of “resource-product-waste-renewable resource” material of steel and iron manufacture, explore a sustainable and environment-friendly way of low input, high output, and low consumption and less emission for the development of steel and iron manufacture.
