Research Abstract	It is important for environmental protection to use waste materials effectively. In this work, we conducted fundamental researches on the application of carbonaceous materials from waste as a reducing agent in an ironmaking process. Carbonaceous materials from waste (carbonized municipal waste and carbonized woody biomass) were mixed with a hematite reagent. The mixtures were heated up at the temperatures of 1000-1200℃ in N_2 gas by using a thermo gravimetric analysis (TG) or a vertical tube electric furnace. As a result, however a reaction of the mixture sample using a graphite stagnated, a reaction of the mixture sample using the carbonized municipal waste and the carbonized woody biomass progressed without the reaction stagnating. This is because a reactivity of the carbonized municipal waste and the carbonized woody biomass is better than that of the graphite.
