For business development and ecological protection, Taiwan government not only established environment protection areas in Taoyuan, Tainan, Kaohsiung and Hualien, but also support the related business such as resource recycling, renewable energy…etc. This study discusses the about electric arc furnace steelmaking dust, one of hazardous industrial waste, riches in divalent metals such as zinc, iron, lead and chromium. Thus, lots of nations devote to the related research and develop their technique of electric arc furnace steelmaking dust recycling. It decreases the influence on the environment of those hazardous materials, and such limited resources can be reuse. To investigate the relationship between the recycling of harmful industrial waste and emissions of pollutants, the research materials used in this article is from A Company’s financial statement, production report, and pollution emissions data. By using the KLEM I-O model, regression analysis and industrial competition analysis, our results show: (1) There is a significant positive relationship between products and electricity costs and investment in the raw flue dust, (2) Pollutant emissions have significant positive relationship with the amount of hazardous waste treatment and material use.
