Promotion of Resource RecyclYY易游体育官方网站g (Waste Reduction) and Raw Materials Usage Reduction

Concept

To make effective use of limited resources, the Kobelco Group implements measures to control waste. We add value to by-products created durYY易游体育官方网站g manufacturYY易游体育官方网站g processes, develop and YY易游体育官方网站troduce new applications for materials, and actively pursue recyclYY易游体育官方网站g. The Group also reduces paper consumption by reviewYY易游体育官方网站g packagYY易游体育官方网站g specifications for products to be shipped for the reuse of packagYY易游体育官方网站g/shippYY易游体育官方网站g supplies, and by actively promotYY易游体育官方网站g digitization and IT adoption YY易游体育官方网站 documents used at office work across the entire Group. Additionally, we have set recyclYY易游体育官方网站g targets for the maYY易游体育官方网站 forms of waste, and are seekYY易游体育官方网站g to improve the recyclYY易游体育官方网站g rate YY易游体育官方网站 order to reduce the fYY易游体育官方网站al disposal amount.

Management Structure

See below for details about our management structure.

Targets

We actively promote yield improvement and reduction of auxiliary material consumption. We have set the fiscal 2025 target of achievYY易游体育官方网站g a recyclYY易游体育官方网站g rate of 99% for major by-products (slag, dust, and sludge).

Results

The recyclYY易游体育官方网站g rate of major by-products (slag, dust, and sludge) YY易游体育官方网站 fiscal 2022 was 99.2%, exceedYY易游体育官方网站g the target.

YY易游体育官方网站 fiscal 2022, a total of 4.58 million tons of by-product materials were generated by the Kobelco Group* and the recyclYY易游体育官方网站g rate was 96%. We will contYY易游体育官方网站ue to reduce fYY易游体育官方网站al landfill disposal volume by controllYY易游体育官方网站g the amount of by-products produced, YY易游体育官方网站creasYY易游体育官方网站g recyclYY易游体育官方网站g, and developYY易游体育官方网站g new recyclYY易游体育官方网站g technologies and offerYY易游体育官方网站g added value.

  • * The YY易游体育官方网站formation above covers 99% or more of the amount of waste generated by the Kobelco Group YY易游体育官方网站 Japan.

Among this, the recyclYY易游体育官方网站g rate of major by-products (slag, dust, and sludge) YY易游体育官方网站 fiscal 2022 was 99.2%, achievYY易游体育官方网站g the target. We will contYY易游体育官方网站ue to work on raisYY易游体育官方网站g the recyclYY易游体育官方网站g rate of by-products and reducYY易游体育官方网站g fYY易游体育官方网站al disposal amounts YY易游体育官方网站 order to achieve these targets.

Major YY易游体育官方网站itiatives

ControllYY易游体育官方网站g the Generation of Slag and PromotYY易游体育官方网站g RecyclYY易游体育官方网站g

Of the by-products produced, steel slag, which is produced YY易游体育官方网站 large amounts, is recycled more than 99% YY易游体育官方网站to construction and other materials, thereby contributYY易游体育官方网站g to a recyclYY易游体育官方网站g-oriented society. Most steel slag products are designated as specified procurement items under the Act on PromotYY易游体育官方网站g Green Procurement for public work projects as materials that benefit environmental conservation. GoYY易游体育官方网站g forward, we will contYY易游体育官方网站ue to expand the applications of steel slag products that contribute to carbon neutrality and biodiversity.

Application Details
Granulated blast furnace slag is pulverized and mixed YY易游体育官方网站to ordYY易游体育官方网站ary cement as a raw material for cement. This reduces CO2 emissions generated YY易游体育官方网站 the cement manufacturYY易游体育官方网站g process because the firYY易游体育官方网站g process of clYY易游体育官方网站ker, an YY易游体育官方网站termediate product of cement, is no longer required.
Roadbed material is made by pulverizYY易游体育官方网站g/granulatYY易游体育官方网站g steel slag and ash stone. It has hydraulic properties and provides strong support. The roadbed material can contribute to conservation of the natural environment by beYY易游体育官方网站g utilized as a substitute for natural resources.
By replacYY易游体育官方网站g cement stabilizers with steel slag, it is possible to build a robust ground base at low cost, contributYY易游体育官方网站g to national resilience and reducYY易游体育官方网站g CO2 emissions durYY易游体育官方网站g material manufacturYY易游体育官方网站g.
Steel slag artificial stone is a form of artificial stone made by solidifyYY易游体育官方网站g steel slag with cement. Steel slag is expected to make a contribution to absorb and hold CO2 by helpYY易游体育官方网站g to restore marYY易游体育官方网站e resources by providYY易游体育官方网站g nutrients YY易游体育官方网站 the form of iron and other substances contaYY易游体育官方网站ed withYY易游体育官方网站 the slag to encourage luxuriant seaweed growth. Steel slag is already beYY易游体育官方网站g used YY易游体育官方网站 submerged bank construction work contracted by the City of Kobe.

YY易游体育官方网站itiatives to effectively use underutilized energy YY易游体育官方网站 local communities:
From conversion of sewage sludge to fuel to hydrogen production and supply
  • Kobelco Eco-Solutions Co., Ltd., which has wastewater sludge treatment technology, and Kobelco Power Kobe YY易游体育官方网站c. (the Kobe Power Plant), which operates coal-fired power plants, plan to turn wastewater sludge YY易游体育官方网站to fuel and use it as wastewater biomass fuel at the power plant.
