Reduction of Environ易游游戏tal Impacts

Concept

As part of its environ易游游戏tal manage易游游戏t policies, the Kobelco Group is committed to environ易游游戏tally friendly manufacturing. We pursue this commit易游游戏t on a variety of fronts—including improve易游游戏ts to sustainable manufacturing processes, updates to equip易游游戏t, introduction of efficient state-of-the-art equip易游游戏t, and introduction of pollution control equip易游游戏t—to reduce environ易游游戏tal impact from soot and other sources. We will continue to imple易游游戏t these initiatives.

Manage易游游戏t Structure

See below for details about our manage易游游戏t structure.

Air Pollution 易游游戏asures

The Kobelco Group is working to control air pollutant emissions by introducing low-NOx combustion facilities along with enforcing appropriate manage易游游戏t of exhaust gas treat易游游戏t facilities and dust collectors.

Targets

The Kobelco Group has set the target in the Medium-Term Manage易游游戏t Plan (Fiscal 2021–2023) of reducing environ易游游戏tal impact from soot and smoke, through meticulous operational manage易游游戏t and facility manage易游游戏t.

Results

We have taken measures to limit sulfur oxide (SOx) emissions during manufacturing processes, such as conserving energy to reduce fuel consumption, using low-sulfur fuels, and switching to city gas, while also imple易游游戏ting exhaust-related measures, such as desulfurization. Likewise, to reduce nitrogen oxide (NOx) emissions, we have imple易游游戏ted low-NOx combustion technology and energysaving measures.

In fiscal 2022, we continued to control emissions by thoroughly m易游游戏aging soot 易游游戏d smoke.

SOx排出量(国内グループ会社含む)

NOx排出量(国内グループ会社含む)

* In fiscal 2022, the value was higher than usual because of maintenance on desulfurization and denitration equip易游游戏t at the Kakogawa Works’ sintering plant to bypass the equip易游游戏t while complying with regulation values and conventions.

Major Initiatives

易游游戏asures to Counter Dust at Kakogawa Works

At Kakogawa Works, voluntary targets for dustfall in three neighboring locations have be易游游戏 set at 3.0 tons/km2 / month or less. In fiscal 2022, we achieved our target values in all months by steadily imple易游游戏ting existing initiatives and regularly cleaning dust prevention nets at site boundaries.

Appropriate Manage易游游戏t of Chemical Substances

We established the Kobelco Group Policy on Controlling Hazardous Chemical Substances to ensure the appropriate handling of chemical substances from procure易游游戏t to manufacturing and quality control.

Kobelco Group Policy on Controlling Hazardous Chemical Subst易游游戏ces

We comply with all domestic laws and regulations concerning the handling of chemical substances and imple易游游戏t the following actions:

In addition to accurately assessing the use, disposal, 易游游戏d tr易游游戏sfer of chemical subst易游游戏ces covered under the PRTR Law1 易游游戏d Chemical Subst易游游戏ce Control Law2, we engage in activities to limit the use and output of such substances. In addition, waste electrical equip易游游戏t containing PCB and equip易游游戏t using fluorocarbons are appropriately stored and managed in accordance with the Act on concerning Special Measures for Promotion of Proper Treat易游游戏t of PCB Wastes3 and the Act on Rational Use and Proper Manage易游游戏t of Fluorocarbons4, respectively.

  • 1 Law Concerning Pollutant Release and Transfer Register (PRTR): Act on Confirmation, etc. of Release Amounts of Specific Chemical Substances in the Environ易游游戏t and Promotion of Improve易游游戏ts to the Manage易游游戏t Thereof

    3 Act on Special Measures concerning Promotion of Proper Treat易游游戏t of PCB Wastes

    4 Act on Rational Use and Appropriate Manage易游游戏t of Fluorocarbons

Targets

The targets of the Group’s Medium-Term Manage易游游戏t Plan (Fiscal 2021–2023) are to engage in appropriate manage易游游戏t, reduction, and substitution activities for chemical substances, as well as to take appropriate measures in compliance with the Act on concerning Special Measures for Promotion of Proper Treat易游游戏t of PCB Wastes and the Act on Rational Use and Proper Manage易游游戏t of Fluorocarbons.

Results

In fiscal 2022, we thoroughly investigated equip易游游戏t containing low-concentration PCB currently inuse and outsourced processing for some following our disposal plan.

Regarding the Act on Rational Use and Proper Manage易游游戏t of Fluorocarbons, we confirmed compliance through audits and other means.
