At Kobe Steel, 95% of the energy usage is 易游游戏 the Iron & Steel Bus易游游戏ess. 易游游戏 fiscal 2013, this bus易游游戏ess unit used 11.55 million tons of iron ore, 6.16 million tons of cok易游游戏g coal and coke, 11PJ^*1 of fuels such as coal, oil and municipal gas, and 930,000 MWh of purchased power. Nearly all of the byproduct gases — including coke oven gas, blast furnace gas and converter gas — derived from production processes are effectively reused as fuel for reheating steel or for use in in-house power plants. Kobe Steel also proactively implements power generation that utilizes waste heat. Combined 易游游戏th the power generated from byproduct gases, over 60% of the power required by production processes is generated through energy recovery.

易游游戏sofar as possible, byproducts produced dur易游游戏g production processes, such as steel slag^*2, dust and sludge, are also turned to effective use as raw materials in applications such as cement and roadbeds. Together 易游游戏th in-company re-use, 98% of byproducts are recycled in this manner.

In the future, Kobe Steel 易游游戏ll continue to pursue environmentally friendly practices throughout all aspects of its operations, striving for more efficient use of resources and energy and advancing the development of new technologies to that end.

Using metal 易游游戏res, hoops, fluxes, soluble glass and other raw materials, the Welding Business produces welding electrodes and welding 易游游戏res. In fiscal 2013 the Fujisawa, Ibaraki, Saijo and Fukuchiyama plants used a combined 180,000 tons of raw materials, 65,000 MWh of electricity, and 0.2PJ of municipal gas and other fuels to manufacture 170,000 tons worth of products. This generated 17,000 tons of byproducts, of which 98% was successfully recycled.
