For the purpose of creating a sustainable environment for the future generation, the government has recognized the importance of renewable resources, and actively takes on the strategies and measures by promoting the industries to recycling wastes in order to effectively improve the physical fitness of the industry. There are various ways to recycle waste materials, depends on the technology and the applications, one waste material can be classified into different ranks of recycled resource. Also, the market value of the recycled resource is judged by its ability to substitute the existing goods on the market. Because of the high proportion of galvanized steel in the steel scrap, zinc would vaporize during the high temperature process; as a result, the electric arc furnace dust (EAF dust) would contain high proportion of zinc. According to the existing recycling technology, the proportion of zinc in EAF dust is around 20% to 30%, which is a valuable secondary resource for producing zinc. This research focuses on the recycling industry; the aim of this research is to find out its future trend and the bottlenecks to be overcome. Hopefully come up with constructive suggestions and specific strategies and measures. The results suggest that the officials should set up standards for recycled products. What is also important is that the government should better plan the policies and regulations for recycling industry. Moreover, the results also show the users of the recycled materials care most about the quality of the product. Hence, the producers of crude zinc oxide should form strategic alliance in order to each the economic scales of production and develop recycling technology to elevate the quality of crude zinc oxide. Once the production meets the market demand, it will be able to expand the sales channels and establish a stable profit.
