Operations that
account for people
and the planet

Natural resources matter to us all

We are working to establish an operating system for business sites that is safe and sustainable for everyone. This includes managing our use of natural resources, recycling resources needed for product development or production processes, removing pollutants, and developing recycling technologies.

We strive to make a
healthy
and safe
workplace

Our approach to
incorporating
sustainability
in operations of
business sites

Managing on-site
waste
Aim to achieve Platinum-level Zero Waste
to Landfill certification* for global
manufacturing sites by 2025
Expand recycling rate and Zero Waste to Landfill certifications
* Zero Waste to Landfill certification from UL(Underwriters Laboratories)
Increase resource circularity of waste
Increase waste recycling and resource efficiency with high value-added activities

Managing On-site Waste

Increase the recycling rate to
achieve Zero Waste to Landfill
certification

Zero Waste to Landfill roadmap

Present - Achieved recycling rate of 96% Recognized for Zero Waste to Landfill for the first time in the semiconductor industry in 2021 *Exclude legally required landfill waste

2023 - Receive Gold level certifications for all business sites

2025 - Earn the highest level (Platinum) certifications for all business sites

Recycling: Rethinking
waste as a resource

We continue to advance the circular economy by discovering added value in waste and developing recycling technologies. Through this, up to 97% waste recycling rate was achieved in 2023.

Efforts to minimize residue in chemical storage drums used in-house, recycling waste wafers, and recycling coffee capsules in offices continued across semiconductor business sites in 2023. This resulted in maintaining the Platinum-level* Zero Waste to Landfill certification, as validated by the global safety science company UL (Underwriters Laboratories).

Waste, a new resource

Our innovative technology drives this change, recycling previously
incinerated and
reclaimed waste.

Waste recycling goals and current status

Efforts to preserve the natural environment

Water resources and air
pollution management roadmap

2030 - Zero increase in water intake for DS (Device Solutions) Division Reuse of discharged water from public sewage treatment plants 100% reduction in global water usage in DX (Device eXperience) Division Increase of water resource reuse and operation of offset projects

2040 - Treat and revert air/water pollutants to natural conditions at semiconductor business sites Develop new technologies that can process at a natural state level

Restore water and air to their natural state

Production processes require water. They also can pollute the atmosphere. We need to work on two fronts: one, saving water, and two, developing technologies to reduce air and water pollutants.

We are reducing the amount of new water withdrawal by maximizing the reuse of water in production processes. Due to the expansion of semiconductor lines, the daily water withdrawal requirement at semiconductor business sites will more than double between 2022 and 2030. However, we have decided to keep the level from 2021 by increasing the reuse of water.

Starting in 2040, we will apply innovative technologies that treat air and water pollutants from semiconductor manufacturing process to a natural state to minimize the impact on the environment.

Managing
Chemicals

We don’t stop at ‘good enough’,
because we care about our
customers and employees’ health
and their environments.

Reducing the use of
hazardous substances
for the health of our
customers and
employees

We strive to minimize any potential adverse effects on the health of our
customers, employees, or to the environment that may arise from
products containing hazardous substances or chemicals used at our
manufacturing sites. We have established and stringently manage
internal regulations that incorporate global environmental standards
such as the EU Directive on the RoHS (Restriction of Hazardous
Substances) and EU REACH (Registration, Evaluation, Authorisation and
Restriction of Chemicals). We will continue to monitor and
systematically respond to new regulatory standards, such as authorized
uses of PFAS (Per- and Polyfluoroalkyl Substances).
