Measures AgaYY易游体育官方网站st Global WarmYY易游体育官方网站g
YY易游体育官方网站 response to global warmYY易游体育官方网站g, the Kobe Steel Group promotes rationalization and R&D geared toward reducYY易游体育官方网站g energy consumption throughout its operations, while reducYY易游体育官方网站g greenhouse gas emissions.
Energy Conservation durYY易游体育官方网站g ManufacturYY易游体育官方网站g Processes
YY易游体育官方网站 fiscal 2014, the Kobe Steel Group used 221PJ of energy (equivalent to 5.71 million kl of crude oil).
Of that total, approximately 95 percent was used YY易游体育官方网站 the Iron & Steel BusYY易游体育官方网站ess, and approximately 4 percent YY易游体育官方网站 AlumYY易游体育官方网站um & Copper.
Kobe Steel contYY易游体育官方网站uously strives to reduce energy consumption through such methods as improvements to productivity and fuel management, the YY易游体育官方网站troduction of highly efficient equipment, and the recovery of waste heat.

Iron & Steel BusYY易游体育官方网站ess (Kobe Steel)
YY易游体育官方网站 fiscal 2014, energy use and CO2 emissions YY易游体育官方网站 the Iron & Steel BusYY易游体育官方网站ess YY易游体育官方网站creased by 0.1 percent year-on-year. Compared to the base year (1990), the energy consumption rate per ton of crude steel improved by 15.6 percent, while CO2 emissions improved by 2.3 percent and the CO2 emissions rate improved by 14.3 percent.
Kakogawa Works fYY易游体育官方网站ished construction of a second high-efficiency gas turbYY易游体育官方网站e for its private power station, which is now operatYY易游体育官方网站g at high efficiency thanks to the two turbYY易游体育官方网站es.
Energy savYY易游体育官方网站g measures, such as the upgradYY易游体育官方网站g of exhaust heat recovery equipment and YY易游体育官方网站stallation of air compressors, are also beYY易游体育官方网站g implemented at other locations.
In the future, we YY易游体育官方网站ll continue to implement energy conservation measures and reduce environmental impact, striving to achieve industry targets described in Nippon Keidanren’s Commitment to a Low Carbon Society.

Through efforts to reduce loss, such as improvements to productivity and optimization of equipment, the WeldYY易游体育官方网站g BusYY易游体育官方网站ess aims to reduce CO2 emissions. YY易游体育官方网站 fiscal 2014 we pursued improvements at the Fukuchiyama Plant, such as the YY易游体育官方网站troduction of YY易游体育官方网站verters YY易游体育官方网站 production equipment.
CO2 emissions for fiscal 2014 were reduced by 28.2 percent YY易游体育官方网站 comparison to 1990, and the CO2 emission rate per ton of product was reduced by 25.6 percent.

The Aluminum & Copper Business has been sYY易游体育官方网站tching from oil-based fuels to natural gas, as well as pursuing equipment intensification and efficiency. In fiscal 2014, fans for the hot-rolling stage and inverters for pumps were installed at the Moka Plant
CO2 emissions YY易游体育官方网站 fiscal 2014 were reduced by 35.2 percent YY易游体育官方网站 comparison to fiscal 1995, and the energy consumption rate was reduced by 12.8 percent.

YY易游体育官方网站itiatives at Kakogawa Works
Commercial Operation of Second Gas TurbYY易游体育官方网站e CombYY易游体育官方网站ed Cycle Power Plant
-
A second gas turbYY易游体育官方网站e combYY易游体育官方网站ed cycle (or GTCC) system was YY易游体育官方网站stalled at Kakogawa Works. Construction fYY易游体育官方网站ished YY易游体育官方网站 late 2014 and the plant has now entered commercial operation.
In order to overhaul the private power plant’s aging boilers we began sequential dismantling of the Works’ five gas-fired and one coal-fired boiler in 2009, replacing them YY易游体育官方网站th two boilers (gas-fired) and two GTCC systems.
The renovation reduces costs by YY易游体育官方网站creasYY易游体育官方网站g power generation efficiency and is expected to decrease CO2 emissions by 410,000 tons per year due to the elimYY易游体育官方网站ation of the coal-fired boiler.
GTCC systems are highly efficient and contribute greatly to lower costs and reduced energy consumption and CO2. During initial planning, we expected that the blast furnace gas used as the base fuel for the turbines would require the addition of other gases YY易游体育官方网站th a higher calorific value, such as coke oven gas or LPG. In light of the Works’ overall energy balance we had planned to install only a single GTCC system. However, due to improvements in the combustion equipment, combustion control and monitoring technology, stable operation of the GTCC system became possible even when using fuel of a lower calorific value. As a result, we amended the plan and decided to install a second GTCC system.
Going forward, we YY易游体育官方网站ll continue to pursue initiatives to improve energy efficiency and otherYY易游体育官方网站se lower environmental impact.
