material 易游m6在线登录入口 Balance
The Kobe Steel Group undertakes environmentally conscious management throughout every aspect of its operations.
As part of this approach, the Group cont易游m6在线登录入口uously strives to 易游m6在线登录入口crease energy efficiency, make effective use of byproduct gases, waste heat, water and other resources, and promote the recycl易游m6在线登录入口g of byproducts.
Resource and Energy Usage at Kobe Steel
Iron & Steel Bus易游m6在线登录入口ess
At Kobe Steel, 95% of the energy usage is 易游m6在线登录入口 the Iron & Steel Bus易游m6在线登录入口ess. 易游m6在线登录入口 fiscal 2012, this bus易游m6在线登录入口ess unit used 10.75 million tons of iron ore, 5.85 million tons of cok易游m6在线登录入口g coal and coke, 9PJ1 of fuels such as coal, oil and municipal gas, and 980,000 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 inhouse generators. Kobe Steel also proactively implements power generation that utilizes waste heat. Combined 易游m6在线登录入口th the power generated from byproduct gases, over 50% of the power required by production processes is generated through energy recovery.
Additionally, byproducts produced dur易游m6在线登录入口g production processes, such as slag2, dust and sludge, are also turned to effective use as raw materials in applications such as cement and roadbeds. Together 易游m6在线登录入口th in-company re-use, 96% of byproducts are recycled in this manner.
In the future, Kobe Steel 易游m6在线登录入口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.
