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.

有效利用废弃物对于环境保护具有重要意义。在这项工作中，我们对废弃物中的碳质材料作为炼铁过程中的还原剂的应用进行了基础研究。将混合物与赤铁矿试剂在N_2气体中通过热重分析(TG)或立式管式电炉加热至1000-1200℃。然而，结果是，使用石墨的混合物样品的反应停滞，而使用碳化城市废物和碳化木质生物质的混合物样品的反应继续进行，而反应没有停滞，这是因为碳化城市废物和碳化木质生物质的反应性。生物质优于石墨。
