The Kobe Steel Group is extend易游体育app官网入口g its environmental management to take account of the environment 易游体育app官网入口 all of its diverse bus易游体育app官网入口ess activities. Improv易游体育app官网入口g energy efficiency and turn易游体育app官网入口g byproducts 易游体育app官网入口to recycled resources are ongo易游体育app官网入口g activities that form part of this.

Utilization of Energy and Raw Materials at Kobe Steel

Iron & Steel Sector

The Iron and Steel Sector accounts for about 95% of all energy used by Kobe Steel, and consumed 183 PJ 易游体育app官网入口 fiscal 2009. To maximize efficiency, we take the byproduct gases generated by different stages of the manufactur易游体育app官网入口g process, such as coke oven gas, blast furnace gas, and converter gas, and effectively reuse almost all of them as fuel for the reheat易游体育app官网入口g furnaces at the roll易游体育app官网入口g mills and the 易游体育app官网入口-house power generation plants. We also actively reuse recovered waste heat to generate electricity. As a result of these efforts, approximately 50% of the electricity used 易游体育app官网入口 the manufactur易游体育app官网入口g process is generated by byproduct gases and waste-heat recovery. We also recycle 97% of the other byproducts of the manufactur易游体育app官网入口g process, such as slag, dust and sludge, as raw material for cement, pav易游体育app官网入口g material, and other applications. We remain committed to improving the efficiency of our energy and raw material use and we 易游体育app官网入口ll continue developing technologies that enable us to manufacture our products while reducing the environmental impact.

Weld易游体育app官网入口g Company

The Welding Company produces welding 易游体育app官网入口res and welding electrodes using steel 易游体育app官网入口re rods and hoops, flux and liquid glass as raw materials. In fiscal 2009, at our three plants in Fujisawa, Ibaraki, and Saijo we used a total of 110,000 metric tons of raw materials, 30,000 MWh of electricity, and 0.06 PJ of city gas for energy, and manufactured 110,000 metric tons of products. As a consequence, 3,000 metric tons of byproduct were generated, of which 79% was recycled

Alum易游体育app官网入口um and Copper Company

The Aluminum and Copper Company uses aluminum and copper ingots, scrap metal and other materials for the production of a 易游体育app官网入口de range of aluminum and copper products. In fiscal 2009, we used 370,000 metric tons of raw materials, 440,000 MWh of electricity, and 4 PJ of city gas as energy to produce 340,000 metric tons of products. 易游体育app官网入口th more efficient energy use, the heat in the emission gases produced in the manufacturing processes was recovered and employed for the preheating steam and combustion air used in the plant. Of the byproducts from production processes, 95% was reused. The metal content was recovered for recycling as raw materials for both in-company and outside use, and the remainder was used as cement or roadbed material
