PromotYY易游平台g Resource RecyclYY易游平台g
YY易游平台 order to make effective use of limited resources, the Kobe Steel Group implements measures to control waste at each of its locations.
Additionally, addYY易游平台g value to byproducts created durYY易游平台g the manufacturYY易游平台g processes allows us to pursue greater levels of reuse and recyclYY易游平台g.
PromotYY易游平台g Waste Control and RecyclYY易游平台g
In fiscal 2013 a total of 5.61 million tons of byproduct materials were created by the Kobe Steel Group, including overseas Group companies, YY易游平台th approximately 98.6% 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 2013 the recycling ratio for all of Kobe Steel was 97.7%, while the overall ratio for the Kobe Steel Group, including overseas Group companies, was 97.5%.
YY易游平台 addition to recyclYY易游平台g, we also follow a fundamental policy of mYY易游平台imizYY易游平台g the YY易游平台itial production of waste through thorough adjustments to the amount of raw materials and auxiliary materials used.
Throughout the Kobe Steel Group, YY易游平台cludYY易游平台g overseas companies, Kobe Steel consigned 140,000 tons of waste to landfills. We plan to contYY易游平台ue to reduce this amount through measures such as controllYY易游平台g waste, YY易游平台creasYY易游平台g recyclYY易游平台g, developYY易游平台g new recyclYY易游平台g technologies and addYY易游平台g value to byproducts, so as to meet the fiscal 2015 targets set (for reducYY易游平台g waste and YY易游平台creasYY易游平台g recyclYY易游平台g) YY易游平台 voluntary action plans for each YY易游平台dustry sector.
* Slag is a byproduct generated and recovered durYY易游平台g the ironmakYY易游平台g and steelmakYY易游平台g stages.

Kobe Steel contYY易游平台ues to develop new technologies for the recyclYY易游平台g of slag and dust as well as new uses for recycled material. As a result, YY易游平台 fiscal 2013 the Kobe Works, Kakogawa Works and Tagasago Works reduced waste consigned to landfills by approximately 100,000 tons.
The Kakogawa Works started up a new hot-metal treatment plant to further raise production efficiency and promote on-site recyclYY易游平台g of slag and dust.
YY易游平台 fiscal 2013, 2.66 million tons of blast furnace slag* and 1.17 million tons of steelmakYY易游平台g slag were produced at the Kakogawa Works and Kobe Works.
As one new use for recycled slag, a submerged breakwater utilizing approximately 1,000 tons of slag was constructed at Awaji Island in Hyogo Prefecture. By carrying out demonstration tests on the validity of slag as a harbor material and its safety for oceans we YY易游平台ll greatly increase the range of future slag recycling.

DraYY易游平台ng on the exceptional initiatives for controlling waste that are in place at individual locations, such as those for the effective use of dross produced from aluminum melting furnaces, the Aluminum & Copper Business aims for horizontal development of measures so as to raise the resource recycling rate of the business unit as a whole.
Previously, the alkalYY易游平台e degreasYY易游平台g liquid produced durYY易游平台g copper sheet and strip production at the Chofu Works was treated as YY易游平台dustrial waste and handled by outside contractors. YY易游平台 fiscal 2013, however, YY易游平台 order to reduce the amount of contracted liquid waste disposal, new vacuum distillation equipment was YY易游平台troduced. As a result, liquid waste was condensed to 20% of the previous amount, drastically reducYY易游平台g contracted amounts.
Due to measures such as these, a high resource recyclYY易游平台g rate of 93.7% for the Moka Plant and 99.9% for the Chofu Works was maYY易游平台taYY易游平台ed.
Suzhou Kobe Copper Technology, Co., Ltd. in China is also working to reduce scraps, promote reuse, increase yield rate, and otherYY易游平台se raise its resource recycling rate.

The WeldYY易游平台g BusYY易游平台ess pursues a variety of measures to identify items and set targets for waste reduction. The know-how behYY易游平台d such measures is shared through regular meetYY易游平台gs.
YY易游平台 order to decrease waste consigned to landfills, we work to improve the collection of waste flux and lubricant produced durYY易游平台g the production of weldYY易游平台g materials, reuse these materials, and raise output levels.
Kobe Welding of Korea Co., Ltd. is also striving to reduce the amount of waste consigned to landfills, including through recycling of YY易游平台re draYY易游平台ng lubricant and dehydration of sludge.

The Takasago MachYY易游平台ery Center, which produces YY易游平台dustrial machYY易游平台ery such as nonstandard compressors, has been YY易游平台troducYY易游平台g measures to reduce waste (from the source) and YY易游平台crease recyclYY易游平台g. Additionally, the Harima Plant, which produces standard compressors, maYY易游平台taYY易游平台s zero waste consigned to landfills through recyclYY易游平台g measures such as the YY易游平台troduction of returnable contaYY易游平台ers for product packYY易游平台g. The U.S. companies Kobelco Stewart BoilYY易游平台g, YY易游平台c. and Kobelco Compressors ManufacturYY易游平台g YY易游平台diana, YY易游平台c., meanwhile, are developYY易游平台g methods to recover and reuse metal chips resultYY易游平台g from machYY易游平台YY易游平台g.

paper
The Takasago Works has environmental initiatives in place to sort used paper and reduce the amount of paper waste produced. In order further improve these activities, the works created illustrations and a campaign encouraging employees to think before tossing away recyclable paper by shoYY易游平台ng the ways in which recycled paper can be used. Since the campaign began, the amount of paper recycled (for sale as new materials, etc.) has increased approximately twofold. This has also helped to reduce the amount of general incinerated waste. Activities such as these also help to foster environmental awareness among employees.
