Abstract
Survey on wastes required for reduction in paper, house, food, printing, pharmaceutical manufacturing and glass manufacturing industries was carried out by a hearing method, and their recycling systems using manufacturing processes of steel products were examined in order to enhance process linkage between the different industries and to decrease wastes emission. Paper sludge in paper, construction and demolition waste wood and waste plaster board in house, waste ion exchange resin in food, incineration ash in printing, inorganic sludge in pharmaceutical manufacturing and chemical division of glass industries were found by hearing of each company. The paper sludge as a sinter material, the construction and demolition waste wood as a blast furnace reductant, and the incineration ash of municipal solid waste as a molten slag by a electric furnace for steelmaking are hopeful from the viewpoint of the progress of their technology, the large treatment amounts and their efficient delivery. The calculated CO2 emission of paper sludge utilization as the sinter material and that of scraped wood as the blast furnace is less than power generation by incineration, while that of molten slag of incineration ash utilized by electric furnace is larger than cement materials.
