In this scenario, there is a lack of clarity aroundpolicies aimed at decarbonization, and carbon

recycling is the recycling of waste into products

Carbon neutrality initiatives● Switching to power from renewableenergy sources (Daiseki Group)
In order to reduce greenhouse gas emissions
associated with our business activities, the DaisekiGroup began, ahead of the schedule set out in our
SBTi target switching to the use of energy fromrenewable sources (renewable energy) in FY2022. We
plan to introduce the use of renewable energy at all
Daiseki Group facilities and in all of our Group
companies by FY2028, reducing our Scope 2 emissions
to zero. In FY2023, Daiseki, Daiseki Eco. Solution, andDaiseki MCR began using renewable energy, and25.3% of the electricity used by the Daiseki Group was
switched to renewable energy.
The Daiseki Group has registered and announced
this plan as part of the RE Action—Declaring 100%
Renewable initiative.

● Reducing electricity use by introducing
turbo blowers (Daiseki Nagoya Worksand Kanto Works)
In FY2023, a turbo blower was introduced to eachof the activated sludge facilities of Daiseki’s NagoyaWorks and Kanto Works. Since activated sludge
facilities supply air to activated sludge, thesefacilities use a large amount of electricity. By
installing turbo blowers with high energy efficiency,
we were able to reduce the electricity used in thesefacilities by approximately 20%.

In FY2023, the Daiseki Group received a B scorein response to our information disclosure throughthe CDP Climate Change 2022 Questionnaire, whichis the same score as the previous fiscal year. In
FY2023, we promoted Task Force on Climaterelated Financial Disclosure (TCFD) scenario
analysis, financial impact analysis of businessactivities by risk and opportunity, third-party
verification of Scope 3 greenhouse gas emissions,and the introduction of energy conservation andrenewable energy. In FY2024, we will further reduce
emissions through the introduction of renewableenergy and provide proactive information disclosurein order to achieve the emission reduction targets
certified by SBTi.

Initiatives to protect the environment and biodiversity
Initiatives to protect the atmosphere
and water environment●M itigation of business-related environmental impact

At Daiseki we are working to reduce environmental
impacts resulting from wastewater, exhaust, odors, andnoise generated in association with the treatment ofindustrial waste.
For all soot and smoke generating facilities ownedby the company, the level of air polluting materials
emitted is measured annually in accordance with the
Air Pollution Control Act, and levels are maintained ator below the standard level. In addition, dust collectors
and humidification equipment have been installed inplants to prevent the generation of dust during thetreatment of industrial waste.
The wastewater we receive is processed first by
neutralizing, coagulating, and dehydrating it; then abiological treatment is applied via the activated sludge
method before it is finally discharged into sewers or
rivers. We have also established our own standards foreach plant that go beyond the legal requirements forthe discharge of drainage water and formulated
emergency response procedures to be followed if a riskof exceeding our own required levels is identified.
As steps to counter unpleasant odors, we analyze
samples of industrial waste before it is delivered to us
and, in cases where it generates significant unpleasantodor, determine in advance whether to accept its
delivery and the treatment methods to be used. We
also install odor-eliminating devices in plants to remove
odors before release into the atmosphere.

Biodiversity initiatives

At Daiseki we believe that in order to protect
biodiversity, it is necessary to prevent thedestruction and pollution of the natural environment,
limit the excessive use of natural resources, prevent
global warming, and eliminate invasive species.
Based on this approach, Daiseki Hokuriku Works
participates in clean-up activities of nearby coastal
areas each year, and is working to protect theenvironment to preserve biodiversity.
For details on Daiseki’s initiatives to protect
biodiversity, refer to the section of our website on
biodiversity.

Detoxification of toxic substances

At Daiseki Group, we accept special control
industrial waste which includes toxic substances suchas strong acids, strong alkalis, and heavy metals, anddetoxify such toxic substances by appropriately
treating them with treatment agents. In FY2023, we
accepted 216,000 tons of special control industrial
waste, and following treatment we sent 11,000 tons ofspecial control industrial waste in the form of remnants,
etc., to an external treatment company. Special control
industrial waste is defined as highly hazardous under
the Waste Management and Public Cleansing Act, andeven small quantities of such waste have an adverse
impact on the natural environment. The Daiseki Group
contributes to preserving the natural environment by
properly treating such toxic substances.
