While the iron and steel industry has witnessed decreased potential in energy savings from technologies internal to the industry, advances in symbiotic technologies with other industries allow for greater energy savings to be found elsewhere. Unfortunately, China currently lacks consideration of symbiotic technologies in planning and constructing industries. This paper assesses a wide range of symbiotic technologies in China. Unique regional characteristics of China's iron and steel enterprises were identified, in consideration with different enterprises (classified into 4 types: port-ecotype, peri-urban, upgradable, and resource-poor). Single objective optimization equations based on cost and cost-effectiveness were used to select the best available technologies for each of the four types, and a bottom-up model was created to analyze their energy savings potentials (expressed as the amount of energy saved when the technologies are utilized to the full extent). Results show that the annual potential for energy savings is 24.55 Mtce in China, which is 6% of total energy consumption of the entire iron and steel industry. Eight technologies account for the largest potentials. The present state of the technologies were analyzed so that policy makers could better understand energy efficiency opportunities and thus implement specific promotion policies.
