Basic approach

Water is a precious resource that keeps us alive and supports our lifestyles, and conserving water resources is an important global issue.

The Toyobo group has committed in the TOYOBO Group Charter of Corporate Behavior to reduce and reuse resources used, including water resources, and to take measures to address environmental risks. In the area of business activities, we are working to minimize the use of water resources and conserve them by promoting water recycling.

Meanwhile, aiming to be a group that "continue to create the solutions needed by people and the earth with materials and science", our group will contribute to the conservation of water resources in Japan and abroad through our seawater desalination business and other activities.


Global Environment Conservation Conference is responsible for formulating and monitoring policies and measures to conserve water resources.

The content of deliberations at Global Environment Conservation Conference will be reported and shared as appropriate by Sustainability Committee through Safety and Disaster Management Division Director.

Board of Directors receives regular reports on the content of discussions at Sustainability Committee, approves key issues such as senior policies and targets, and oversees the progress of activities.

Identifying risks

To identify water risks (water stress, drought, flooding, water quality, etc.) in the operations of our business sites around the world, we use the AQUEDUCT Water Risk Atlas published by the World Resources Institute (WRI) to conduct our annual periodic assessment. In addition, if there is a change in the planned construction of a plant, an extraordinary assessment is conducted at that time to confirm the risks prior to the construction of a new site.

As a result, our two business sites in Thailand and Saudi Arabia were assessed as having high risk in terms of the amount of water available (existence of risk of drought occurrence and variation in the amount of water available from year to year).

Based on these results, we discussed with the relevant departments and confirmed the following for the two sites concerned.

  • Located in an industrial park that is properly managed under the regulations of the country where the site is located, and measures are in place to minimize risk to an extent feasible (e.g., water supply backup system, etc.).
  • Water consumption is less than 0.1% of the Toyobo's total water intake.

The group therefore does not currently consider itself to be exposed to any water risks that could have a significant financial or strategic impact.


The following table shows the water intake by region for fiscal 2023.

Despite a more than 6% increase in sales in fiscal 2023 compared to the previous year, the group's water intake was kept at a slight increase of about 0.3% over last year, as a result of ongoing water conservation efforts at each site to reduce the amount of water intake.

  • High-risk regions: Regions rated as high risk in terms of the amount of water available in the AQUEDUCT Water Risk Atlas.
  • Low-risk regions: Regions other than high-risk areas.

Environmental compliance

Three years from fiscal 2021 to fiscal 2023, there were no regulatory violations related water quantity permits, standards and regulations.


Risk reduction

Water resource management

Our group promotes appropriate management of water resources through improvements in manufacturing processes, water conservation activities, and the use of recycled water.

Water resource management

Water reusing and recycling system

Our group's manufacturing facilities process includes the cooling process for plastic resin products. Water used as cooling water is repeatedly used without being discharged.

Collaboration with local community

The Tsuruga Research and Production Center of our group participates in the ”Tsuruga City Water Environment Improvement Roundtable,” which consists of local government officials, academics, residents, companies, and NGOs that have come together for the purpose of groundwater management. The report provides information on measures to achieve the reduction targets promised to the local government and citizens, as well as the results of activities and future plans.

Identifying opportunities

Contributing to the elimination of water shortage through business operations

Almost all of the water covering the globe is seawater, with limited quantities of the fresh water that we use. As a result, regions where fresh water is difficult to use are facing water shortages. The Middle East and the Gulf region in particular are seeing ongoing, remarkable economic development, with improved living standards and increased populations. As a result, securing water for both industrial and domestic use has become problematic, and the introduction of desalination plants* is underway. The Toyobo group supplies the membranes used in seawater desalination facilities, thereby helping to eliminate water shortages in these regions.

  • Seawater desalination facilities: These removes the various salts present in seawater in order to produce fresh water, providing water for drinking and industrial use.

Expansion of opportunities.

HOLLOSEP® hollow fiber reverse osmosis membranes

The Toyobo group's hollow fiber type reverse-osmosis (RO) membrane element HOLLOSEP® is a membrane that contributes to desalination of seawater. It boasts high water recovery rate, offers superior chlorine tolerance, and can inhibit the proliferation of microorganisms through chlorine sterilization. We produce high quality drinking water in the Middle East and Gulf countries that have high-temperature, highly saline seawater, harsh conditions for reverse osmosis membranes. With over 30 years' usage, these are highly acclaimed and hold a high market share. These are also used domestically, in Japan's largest seawater desalination plant.
