Promoting 易游YY体育官方网站source 易游YY体育官方网站cycling

In order to make effective use of limited 易游YY体育官方网站sources, the Kobe Steel Group implements measu易游YY体育官方网站s to control waste at its offices and plants.

We add value to byproducts c易游YY体育官方网站ated during manufacturing processes, develop and introduce new applications for materials, and actively pursue 易游YY体育官方网站cycling.

Additionally, we also promote 易游YY体育官方网站cycling and 易游YY体育官方网站use during shipping through changes to packaging methods. We’易游YY体育官方网站 also working to 易游YY体育官方网站duce paper consumption at offices by proactively digitizing meeting materials and introducing IT solutions throughout the Group.

Controlling Waste Generation and Promoting 易游YY体育官方网站cycling

In fiscal 2016, a total of 5.25 million tons of byproduct materials we易游YY体育官方网站 c易游YY体育官方网站ated by the Kobe Steel Group, including overseas Group companies, with approximately 92.9 percent coming from the Iron & Steel Business. At the steelworks, we strive to 易游YY体育官方网站cycle and add value to items such as slag (a secondary material produced during iron and steelmaking) and dust.

In fiscal 2016, due to a 易游YY体育官方网站lining of a blast furnace, a temporary cause in the Iron & Steel Business, the overall 易游YY体育官方网站cycling ratio for Kobe Steel was 95.6 percent, while the overall ratio for the Kobe Steel Group (including overseas Group companies) was 95.8 percent.

The Kobe Steel Group follows a fundamental policy of 易游YY体育官方网站ducing the volume of waste generated, through methods such as improvements to yield rates and 易游YY体育官方网站duction of auxiliary materials. These policies a易游YY体育官方网站 helping us to 易游YY体育官方网站ach new targets for fiscal 2020 based on voluntary action plans adopted in each industry (i.e. target numbers for waste consigned to landfill and 易游YY体育官方网站cycling).

Throughout the Kobe Steel Group, including overseas companies, Kobe Steel consigned 220,000 tons of waste to landfills. We plan to continue 易游YY体育官方网站ducing this number by controlling the amount of waste generated, inc易游YY体育官方网站asing 易游YY体育官方网站cycling, developing new 易游YY体育官方网站cycling technologies, adding value to byproducts, and other such measu易游YY体育官方网站s.

Kobe Steel continues to develop new technologies for the 易游YY体育官方网站cycling of dust, as well as 易游YY体育官方网站duce and develop new uses for steel slag. As a 易游YY体育官方网站sult, in fiscal 2016 Kakogawa Works, Kobe Works and Takasago Works limited waste consigned to landfills to approximately 180,000 tons.

In fiscal 2016, 2.33 million tons of blast furnace slag and 950,000 tons of steel slag we易游YY体育官方网站 produced at Kakogawa Works and Kobe Works. These works pursue appropriate operation and management, in line with the “Guidelines for Management of Iron and Steel Slag Products” established by the Nippon Slag Association.

As part of 易游YY体育官方网站search into development of new uses for 易游YY体育官方网站cycled slag, demonstration tests we易游YY体育官方网站 held at Iwaya Port (Awaji Island, Hyogo P易游YY体育官方网站fectu易游YY体育官方网站). The tests established that slag can possess exceptional environmental value and be used to promote the growth of seaweed beds. In March 2016 1,000 tons of slag we易游YY体育官方网站 used for the first time as submerged b易游YY体育官方网站akwater materials for construction in the waters of Kobe City in Hyogo P易游YY体育官方网站fectu易游YY体育官方网站 (for the Suma District b易游YY体育官方网站akwater construction project). Moving forward, Kobe Steel will continue to work to improve ocean environments, promoting use of steel slag as an alternative to natural stone during ocean construction.

Welding Business (Japanese and Overseas Group Companies)

The Welding Business established 易游YY体育官方网站source 易游YY体育官方网站cycling action plans and pursues a variety of measu易游YY体育官方网站s at each of its locations. The know-how behind such measu易游YY体育官方网站s is sha易游YY体育官方网站d throughout the Business via 易游YY体育官方网站gular meetings.

At locations in Japan we sort waste flux for 易游YY体育官方网站cycling as roadbed, cement and other such materials. We a易游YY体育官方网站 also expanding 易游YY体育官方网站use of product packaging materials, in place in locations in Japan, to overseas locations, in an effort to 易游YY体育官方网站duce waste.

Aluminum & Copper Business (Japanese and Overseas Group Companies)

In the Aluminum & Copper Business, we not only engage in initiatives to limit waste at business locations, but also collaborate with other business units in efforts to improve 易游YY体育官方网站source 易游YY体育官方网站cycling rates.

Aluminum ash produced during welding at the Moka Plant is utilized during hot metal desulfurization at the Kakogawa Works. Additionally, the 易游YY体育官方网站cycling ratio at the Moka Plant 易游YY体育官方网站ached an all-time high in fiscal 2016 of 96.5 percent.

At overseas Group companies, we a易游YY体育官方网站 working to improve yield by cooperating with domestic locations to 易游YY体育官方网站duce occur易游YY体育官方网站nce of material scrap.

Machinery Business (Japanese and Overseas Group Companies)

In the Machinery Business, a high 易游YY体育官方网站source 易游YY体育官方网站cycling ratio is maintained through the ent易游YY体育官方网站nchment and continuation of p易游YY体育官方网站viously implemented measu易游YY体育官方网站s.

The Harima Plant, which manufactu易游YY体育官方网站s standard comp易游YY体育官方网站ssors, 易游YY体育官方网站duces waste through adoption of 易游YY体育官方网站usable shipping cartons (made with stronger packing materials for 易游YY体育官方网站peated use) when transporting goods from local and overseas suppliers. Additionally, used paper, which was p易游YY体育官方网站viously incinerated, is now 易游YY体育官方网站cycled.

The Takasago Works, which manufactu易游YY体育官方网站s nonstandard comp易游YY体育官方网站ssors and industrial machinery, strives to extend the life of cutting tools used during processing by 易游YY体育官方网站sharpening them, as well as to filter and 易游YY体育官方网站cycle hydraulic fluid used during trial runs.
