Fig. 6 showed the current symbiotic network in Liuzhou case. There were three symbiotic activities identified, mainly were traditional material or energy exchange, including BF slag reused to produce slag powder, BF/steel slag utilized by cement and construction industry, by-product from the desulfurization process utilized to produce fertilizer. Recently a new energy exchange chain that providing coke oven gas and steam to chemical industry (producing ammonia) was under construction. It was noted that although LIS made a great progress in energy conservation and emissions reduction, it had little symbiotic linkage with the other industrial or social community.
