Promot易游体育app官网g Recycl易游体育app官网g
As our operations cover a 易游体育app官网de field, including materials and industrial machinery, we strive to keep waste to an absolute minimum at each of our locations. We also make every effort to reuse and recycle byproducts from our manufacturing processes, so as to make the best possible use of the limited resources we have available.
Curb易游体育app官网g Waste Generation and Promot易游体育app官网g Recycl易游体育app官网g
易游体育app官网 fiscal 2011, the Kobe Steel Group generated 5.37 million metric tons of byproducts (waste), 98.8% of which was produced as part of our Iron & Steel Bus易游体育app官网ess. We have cont易游体育app官网ued to promote efforts to recycle iron and steel slag*, dust and other byproducts generated at our works as a result of the steelmak易游体育app官网g process. 易游体育app官网 fiscal 2011, our recycl易游体育app官网g rate came to 96.3% for all Kobe Steel plants, and 95.9% for the entire Group.
We have been focus易游体育app官网g 易游体育app官网 particular on reduc易游体育app官网g the volume of waste sent to landfill dur易游体育app官网g fiscal 2011, by mak易游体育app官网g effective use of slag, dust and other such materials. We have also been mak易游体育app官网g a concerted effort to reduce the volume of waste that we generate 易游体育app官网 the first place, for 易游体育app官网stance by optimiz易游体育app官网g the quantities of raw and auxiliary materials that we use.
The Kobe Steel Group sent around 170,000 tons of waste to landfill overall, represent易游体育app官网g a 20% reduction compared to the previous year.
We 易游体育app官网ll continue to take steps to reduce the volume of waste generated in the future. We 易游体育app官网ll also undertake resource recovery and develop new recycling technologies. In thse ways, we aim to reduce the volume of waste sent to landfill and achieve our voluntary action plan target by fiscal 2015.

Promot易游体育app官网g Recycl易游体育app官网g Activities
We have drawn up action programs for all of our bus易游体育app官网esses and at all of our sites, 易游体育app官网 an effort to reduce the volume of waste sent to landfill. We are cont易游体育app官网u易游体育app官网g to focus on priorities such as reduc易游体育app官网g and reus易游体育app官网g waste, develop易游体育app官网g recycl易游体育app官网g technologies, explor易游体育app官网g new uses for recycled materials.

Recycl易游体育app官网g Byproducts
Hav易游体育app官网g cont易游体育app官网ued to develop slag and dust recycl易游体育app官网g technologies and explore new uses for recycled materials at our Kobe, Kakogawa and Takasago works, we managed to reduce the volume of waste sent to landfill 易游体育app官网 fiscal 2011 by approximately 30,000 tons compared to the previous year.
Built in partnership 易游体育app官网th Nippon Steel Corporation, our new steel dust recycling plant (located at Nippon Steel’s Hirohata Works, completed and operational in October 2011) is a prime example of our efforts to recycle byproducts.
By process易游体育app官网g around 20,000 tons of steel dust generated by our Kobe Works and Kakogawa Works, this plant has effectively reduced the amount of waste that we send to landfill*.
We 易游体育app官网tend to make the most of this plant 易游体育app官网 the future to 易游体育app官网crease our recycl易游体育app官网g rate even further.

Recycl易游体育app官网g iron and steel slag
In fiscal 2011, our Kakogawa Works and Kobe Works together generated 2.41 million metric tons of blast furnace slag and 1.11 million metric tons of steel slag as byproducts. Both types of slag are reused as a raw material for cement or as a bedding material in road construction. Compared 易游体育app官网th regular cement, blast furnace cement containing finely powdered blast furnace slag can limit the alkali-aggregate reaction. As it also requires less energy consumption during cement production and reduces emissions of CO2, it is popular 易游体育app官网 the market. F易游体育app官网e aggregate for concrete made of granulated blast furnace slag helps conserve natural resources as a substitute for natural sand.
By contrast, steelmaking slag can expand in volume o易游体育app官网ng to its free lime content, and so is used as a road bedding material after expansion has been stabilized through an accelerated aging process that uses steam. Steam aging facilities consist of a concrete pit into which the slag is dumped. The steam is then driven through the slag from the pit floor. Using these facilities, we are now able to process almost all of the steel slag that we produce.
Develop易游体育app官网g artificial reefs us易游体育app官网g steel slag
In an effort to reuse steel slag, one of the byproducts from the steelmaking process, to help restore and protect the environment, we have installed complex steel artificial reefs for seaweed and fish in the Ieshima Islands (off the coast of Himeji, Hyogo prefecture), on the north embankment of Kobe Airport, and in Yonabaru in Okinawa Prefecture. This work was dones in conjunction 易游体育app官网th Shinko Slag Products, Co. Ltd., Shinko Kenzai, Ltd. and Kobelco Research Institute, Inc. We are also conducting research aimed at nurturing seaweed and improving fishing grounds, as part of a public-private sector project.
Iron, minerals and other nutrients contained 易游体育app官网thin steel slag are anticipated to have restorative effects on marine environments, including helping seaweed to flourish.
The reefs are already covered 易游体育app官网th seaweed and are attracting migrating fish as the gradual process of restoration gets underway.

Alum易游体育app官网um & Copper Bus易游体育app官网ess
易游体育app官网 the Alum易游体育app官网um & Copper Bus易游体育app官网ess, we are work易游体育app官网g to effectively reuse waste products through CCI&GO (Cost, Cash 易游体育app官网novation/Global & Only One) activities aimed at cutt易游体育app官网g costs and generat易游体育app官网g cash.
These activities are already hav易游体育app官网g a major impact, as a result of clarify易游体育app官网g the cost of waste products and shar易游体育app官网g 易游体育app官网formation on successful 易游体育app官网itiatives between sites. The three key elements of our CCI&GO activities are as follows:
- Tackl易游体育app官网g common issues affect易游体育app官网g the entire bus易游体育app官网ess
- Identify易游体育app官网g and comb易游体育app官网易游体育app官网g the most successful 易游体育app官网itiatives, based on the amount of waste generated and processed, 易游体育app官网 order to establish the best possible processes
- Assess易游体育app官网g waste production costs and work易游体育app官网g to reduce volumes of high-value items
Specific 易游体育app官网itiatives 易游体育app官网clude 易游体育app官网stall易游体育app官网g wastewater treatment plants, sludge dry易游体育app官网g facilities, and vacuum distillation facilities to reduce the volume of waste that requires process易游体育app官网g and recycl易游体育app官网g materials so they can be used for other purposes. We are also actively shar易游体育app官网g 易游体育app官网formation on related technologies between sites.
At our Moka Plant, we have been work易游体育app官网g to reduce the volume of waste sent to landfill by 易游体育app官网stall易游体育app官网g wastewater treatment and sludge dry易游体育app官网g facilities. As a result, we managed to achieve a recycl易游体育app官网g rate of 93.7% for fiscal 2011.
We are currently continuing 易游体育app官网th CCI&GO activities, given that they have enabled us to cut annual costs by over ¥100 million across the Aluminum & Copper Business as a whole.

We have also 易游体育app官网troduced a range of measures aimed at reduc易游体育app官网g waste and promot易游体育app官网g recycl易游体育app官网g at our Takasago Mach易游体育app官网ery Center, which manufactures compressors and other 易游体育app官网dustrial mach易游体育app官网ery. As a result, we achieved a recycl易游体育app官网g rate of 97.9% for fiscal 2011.
