Material Balance
The デュエルビッツ 入金不要ボーナスel Group is extending its environmental management to take the environment into account in all its diverse business activities. Improving energy efficiency and turning byproducts into recycled resources are ongoing activities that form part of this.
Utilization of Raw Materials and Energy at デュエルビッツ 入金不要ボーナスel
Iron & Steel Business
Our Iron & Steel Business accounts for 95% of all energy used at デュエルビッツ 入金不要ボーナスel. In fiscal 2011, we consumed 11.35 million metric tons of iron ore, 5.95 million metric tons of coke and coking coal, 10 PJ of fuels such as coal, oil and city gas, and 1.04 million MWh of purchased 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 reheating furnaces at the rolling mills and the in-house power generation plants. We also actively reuse recovered waste heat to generate electricity. Combined with byproduct gases, this means that over 50% of the power that we use in our production processes is generated from recovered energy sources.
We also recycle 97% of the other byproducts of the production process, such as iron and steel slag*, dust and sludge, as raw materials for cement, paving material, and other applications.
We remain committed to improving the efficiency of our raw material and energy use, and we will continue developing technologies that enable us to manufacture our products while preserving the environment.
*Iron and steel slag: Byproduct separated and recovered from molten metal during the refining process

Welding Business
The Welding Business produces welding wires and welding electrodes using steel wire rods and hoops, flux and liquid glass as raw materials. In fiscal 2011, our plants in Fujisawa, Ibaraki, Saijo and Fukuchiyama used a total of 200,デュエルビッツ 入金不要ボーナスetric tons of raw materials, 70,デュエルビッツ 入金不要ボーナスWh of electricity, and 0.2 PJ of city gas for energy. We manufactured 180,デュエルビッツ 入金不要ボーナスetric tons of welding products. As a consequence, 11,デュエルビッツ 入金不要ボーナスetric tons of byproducts were generated, of which 96% were recycled.

Kobe Welding Wire Co. Ltd. was merged into デュエルビッツ 入金不要ボーナスel's Fukuchiyama Plant in 2011 and is therefore included in the above figures.
Aluminum & Copper Business
The Aluminum & Copper Business uses aluminum and copper ingots, scrap metal and other materials for the production of a wide range of aluminum and copper products. In fiscal 2011, we used 350,デュエルビッツ 入金不要ボーナスetric tons of raw materials, 450,デュエルビッツ 入金不要ボーナスWh of electricity, and 3.5 PJ of city gas as energy to produce 340,デュエルビッツ 入金不要ボーナスetric tons of products.
Despite producing 27,デュエルビッツ 入金不要ボーナスetric tons of waste, including slag and dust from melting and casting and waste sludge, we managed to recycle 96% of that total.
