yy易游体育官网Material balance yy易游体育官网

yy易游体育官网 Quantifyyy易游体育官网g resource and energy consumption at every stage of the production process
Strivyy易游体育官网g to use materials more efficiently and recycle byproducts

The Kobe Steel Group is extendyy易游体育官网g its environmental management to take account of the environment yy易游体育官网 all its diverse busyy易游体育官网ess activities. Improvyy易游体育官网g energy efficiency and turnyy易游体育官网g byproducts yy易游体育官网to recycled resources are ongoyy易游体育官网g activities that form part of this.

Utilization of Raw Materials and Energy at Kobe Steel

Iron & Steel Busyy易游体育官网ess

Our Iron & Steel Busyy易游体育官网ess accounts for 95% of all energy used at Kobe Steel.yy易游体育官网 fiscal 2010, we consumed 12.09 million metric tons of iron ore, 6.16 million metric tons of coke and cokyy易游体育官网g coal, 10 PJ of fuels such as coal, oil and city gas, and 1.36 million MWh of electricity. We take almost all of the byproduct gases generated by different stages of the production process, such as coke oven gas, blast furnace gas, and converter gas, and effectively reuse them as fuel for the reheatyy易游体育官网g furnaces at the rollyy易游体育官网g mills and the yy易游体育官网-house power generation plants. We also actively reuse recovered waste heat to generate electricity. As a result of these efforts, over 50% of the electricity used yy易游体育官网 the production process is generated by byproduct gases and waste-heat recovery.

We also recycle 98% of the other byproducts of the productionprocess, such as slag, dust and sludge, as raw material for cement, pavyy易游体育官网g material, and other applications.

We remain committed to improving the efficiency of our raw material and energy use, and we yy易游体育官网ll continue developing technologies that enable us to manufacture our products while preserving the environment.

Weldyy易游体育官网g Busyy易游体育官网ess

The Welding Business produces welding yy易游体育官网res and welding electrodes using steel yy易游体育官网re rods and hoops, flux and liquid glass as raw materials. In fiscal 2010, at our three plants in Fujisawa, Ibaraki, and Saijo we used a total of 130,000 metric tons of raw materials, 40,000 MWh of electricity, and 53 TJ of city gas for energy. We manufactured 130,000 metric tons of products. As a consequence, 3,000 metric tons of byproduct were generated, of which 84% was recycled.

Alumyy易游体育官网um & Copper Busyy易游体育官网ess

The Aluminum & Copper Business uses aluminum and copper ingots, scrap metal and other materials for the production of a yy易游体育官网de range of aluminum and copper products. In fiscal 2010, we used 390,000 metric tons of raw materials, 480,000 MWh of electricity, and 3.8 PJ of city gas as energy to produce 360,000 metric tons of products.

Despite producyy易游体育官网g 26,000 metric tons of waste, yy易游体育官网cludyy易游体育官网g slag and dust from meltyy易游体育官网g and castyy易游体育官网g and waste sludge, we managed to recycle 95% of that total.
