Abstract May of 1999, Belgium's crisis over dioxin contamination in food is set to cost the country's Treasury an estimated 35 billion Belgian francs ($898.8 million), a government source record showed. On this occasion, international or community or national representative presented a report on the contamination of animal feed with dioxins including information about the chronology of the events were taken action to Dioxin. One of the biggest threats to public health is posed by a chemical known as Dioxin. Dioxin is the most toxic chemicals known to human-beings, its potency is second only to radioactive waste. Dioxin is created as an accidental byproduct during the manufacturing, and incineration process of Chlorine based products. Once released in to the environment, its contamination becomes very wide spread. Dioxin is very long lasting, and has the ability to accumulate in living tissues. It is present in your body from the moment that you are born, to the moment you die. There is no safe level of Dioxin that a person can be exposed to, the smallest amounts have bean proven to significantly increase the chances of developing cancer, as well as various other health defects. The Environmental Protection Agency (EPA) in Taiwan has been working on publishing a study of the health problems associated with dioxin. The EPA has done reassessment to the 32 possible dioxin polluted industries in Taiwan, such as waste incineration, chemical and pesticide manufacturing. The data and report has been collected and released to a final form. The Dioxin Assessment Report is measured to be the allowed contamination polluted figures toward the manufacturing industries. Especially toward arc furnace Steel industries, the dioxin assessment shows that 80.6% of Dioxin pollution is exposed by the steel industries. By the end of year 2001, Taiwan¡¦s EPA is released a ¡§Restriction of Dioxin Expose Policies and Procedures for Arc Furnace Steel Industry¡¨. The standard intake of Dioxins for new equipped arc furnace steel business from January 1, 2002 should below 0.5 ng-TEQ/Nm3. For the existing arc furnace steel industries, the 5 ng-TEQ/Nm3 regulation will be followed as a rule by the beginning of 2004. After the year of 2007, the existing arc furnace steel industries will be strictly followed the 0.5 ng-TEQ/Nm3 Dioxin Exposed Regulation. By comparison to other steel business in Japan, China, Russia and The United States, the Dioxin Exposed Regulation is harsher in Taiwan other than those countries. The purpose of this thesis is based upon the arc furnace steel manufacturing business in Taiwan. With the forbid Dioxin Exposed Regulation ruled by EPA in Taiwan, how to rebuild and sustain the arc furnace steel business in the competitive strategies while regulation and environmental challenges.
