Resource and Energy Usage at デュエルビッツ 出金el
Iron & Steel Business
At デュエルビッツ 出金el, 95% of the energy usage is in the Iron & Steel Business. In fiscal 2013, this business unit used 11.55 million tons of iron ore, 6.16 million tons of coking 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. デュエルビッツ 出金el also proactively implements power generation that utilizes waste heat. Combined with the power generated from byproduct gases, over 60% of the power required by production processes is generated through energy recovery.
Insofar as possible, byproducts produced during 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 with in-company re-use, 98% of byproducts are recycled デュエルビッツ 出金is manner.
In the future, デュエルビッツ 出金el will 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.
