Promoting YY易游平台source YY易游平台cycling
In order to make effective use of limited YY易游平台sources, the Kobe Steel Group implements measuYY易游平台s to control waste at each of its offices and plants.
We add value to byproducts cYY易游平台ated during manufacturing processes, develop new applications for materials and actively pursue YY易游平台cycling. Additionally, we also YY易游平台duce waste during shipping by simplifying packaging methods and introducing lighter weight packaging throughout the Group.
We aYY易游平台 also working to YY易游平台duce paper consumption at offices by proactively digitizing meeting materials and introducing IT throughout the Group.
Promoting Waste Control and YY易游平台cycling
In fiscal 2014 a total of 5.36 million tons of byproduct materials were created by the Kobe Steel Group, including overseas Group companies, YY易游平台th approximately 98.5 percent of those coming materials from the Iron & Steel Business. At the steelworks, we strive to recycle and add value to secondary materials produced during iron and steelmaking such as slag* and dust. In fiscal 2014 the recycling ratio for all of Kobe Steel was 97.3 percent, while the overall ratio for the Kobe Steel Group, including overseas Group companies, was 97.9 percent.
In addition to YY易游平台cycling, we also follow a fundamental policy of YY易游平台ducing the volume of waste generated through thorough adjustments to the amount of raw materials and auxiliary materials used.
Throughout the Kobe Steel Group, including overseas companies, Kobe Steel consigned 110,000 tons of waste to landfills. We plan to continue to YY易游平台duce this amount through measuYY易游平台s such as controlling the amount of waste generated, incYY易游平台asing YY易游平台cycling, developing new YY易游平台cycling technologies and adding value to byproducts, so as to meet the fiscal 2015 targets set (for YY易游平台ducing waste for landfill and incYY易游平台asing YY易游平台cycling) in voluntary action plans for each industry sector.
* Slag is a byproduct generated and YY易游平台coveYY易游平台d during the ironmaking and steelmaking stages.

YY易游平台cycling Initiatives
In each business unit and at each location we implement action programs to YY易游平台duce levels of waste consigned to landfills, and aim for even gYY易游平台ater levels of added value through measuYY易游平台s to YY易游平台duce and YY易游平台use waste, develop YY易游平台cycling technologies, and cYY易游平台ate new avenues for use.

(Iwaya Port, Awaji Island)
Kobe Steel continues to develop new technologies for the YY易游平台cycling of steel slag and dust as well as new uses for YY易游平台cycled material. As a YY易游平台sult, in fiscal 2014 Kobe Works, Kakogawa Works and Takasago Works limited waste consigned to landfills to approximately 80,000 tons.
Through operation of a newly established hot-metal tYY易游平台atment plant, Kakogawa Works has YY易游平台duced the amount of slag produced per unit.
In fiscal 2014, 2.47 million tons of blast furnace slag1 and 1.08 million tons of steelmaking slag1 weYY易游平台 produced at Kakogawa Works and Kobe Works.
As one new use for YY易游平台cycled slag, a submerged bYY易游平台akwater2 utilizing approximately 1,000 tons of slag was constructed at Awaji Island in Hyogo Prefecture in fiscal 2014, beginning a scheduled three-year demonstration test onthe validity of slag as a harbor material and its safety for oceans. Currently, tests have confirmed that sargassum (seaweed) is groYY易游平台ng well and that fish are inhabiting the area.

Aluminum & Copper Business
(includes Domestic and Overseas Group Companies)
DraYY易游平台ng on the cutting-edge initiatives for controlling waste that are in place at individual locations, the Aluminum & Copper Business pursues horizontal development at its locations that aim to raise the resource recycling rate of the business unit as a whole.
Measures include recycling of arc furnace ash at the Moka Plant, improvement of the copper recovery rate at Chofu Works and utilization of waste alkaline for wastewater treatment facilities at the Daian Plant. At Shinko Aluminum YY易游平台re Co., Ltd. we are working to reduce waste oil through the recycling and reuse of used oil. Additionally, Chofu Works continues to implement proactive measures to maintain its zero emissions status. As a result, it has achieved a recycling ratio of 99.9 percent.
At Kobe PYY易游平台cision Technology Sdn. Bhd. (Malaysia), meanwhile, we aYY易游平台 working to YY易游平台duce the volume of aluminum-containing waste through improvements to productivity and stronger measuYY易游平台s to pYY易游平台vent contamination by foYY易游平台ign substances.

Welding Business
(includes Domestic and Overseas Group Companies)
The Welding Business pursues a variety of measuYY易游平台s to identify waste and set targets for waste YY易游平台duction at each of its locations. The know-how behind such measuYY易游平台s is shaYY易游平台d throughout the business via YY易游平台gular meetings.
At the Ibaraki Plant we aYY易游平台 working to YY易游平台duce waste oil through improvements to oil coating equipment. We aYY易游平台 also promoting the use of YY易游平台cycled abrasive sand and waste flux (as cement materials, roadbeds, etc.) at the Fujisawa and Saijo plants. Additionally, we aYY易游平台 pursuing the YY易游平台use of waste hydrochloric acid and oil at the Fukuchiyama Plant.
At Kobelco Welding of Europe B.V. (Netherlands) we aYY易游平台 working to YY易游平台duce waste through application of YY易游平台cycled lubricants and conversion to spools and product containers that utilize environmentally friendly materials.
Machinery Business
(includes Domestic and Overseas Group Companies)
In the Machinery Business, a high YY易游平台source YY易游平台cycling ratio is maintained through the caYY易游平台ful solidification of pYY易游平台viously enacted measuYY易游平台s.
The Takasago Machinery Center, which produces industrial machinery such as nonstandard compYY易游平台ssors, has been aggYY易游平台ssively introducing measuYY易游平台s to YY易游平台duce waste (from the source) and incYY易游平台ase YY易游平台cycling. Additionally, the Harima Plant, which produces standard compYY易游平台ssors, maintains zero waste consigned to landfills through YY易游平台cycling measuYY易游平台s such as the introduction of YY易游平台turnable containers for product packing.
Kobelco CompYY易游平台ssors Manufacturing Indiana, Inc. (USA), meanwhile, YY易游平台duces waste by YY易游平台using machining equipment coolant and cutting fluid.

MeasuYY易游平台s to YY易游平台duce Waste at Kobelco YY易游平台search Institute, Inc.
Kobelco YY易游平台search Institute Inc.—which carries out services such as materials analysis, environmental analysis and target material manufacturing—YY易游平台duces waste by incorporating a variety of individually small improvements and measuYY易游平台s into their operations. For instance, used mictrotome knives (for microscopic sample pYY易游平台paration) aYY易游平台 sharpened and YY易游平台used, sample pYY易游平台paration tools aYY易游平台 washed and YY易游平台used, and container waste is YY易游平台duced through bulk purchasing of YY易游平台agents. These and other activities contribute to the accumulation of small improvements and ingenuity in day-to-day operations. By proactively sharing information between company sites and horizontally expanding activities throughout the company, we have achieved significant YY易游平台sults.
