Water Resources

Policy and Approach

The world's supply of fresh water is limited. The Toyobo Group is striving to conserve water sources both within Japan and overseas through products and businesses such as our desalination business, and we are promoting the recycling and efficient usage of water in our business activities.


Policies for the protection of water resources are discussed by the Global Environment Committee under the Sustainability Committee, and this plans to decide on future policies.

Targets and Results

Based on the above policy, we are currently considering setting target values for water resources, and studying water risks in the areas where we operate. Water draw and discharge results are as below.

In the three years from FY2018 to FY2020, there were no regulatory violations or incidents related to water quality or quantity.

Water draw


FY Japan Overseas
2018 90,769 1,326
2019 86,406 1,162
2020 89,139 1,408



FY Japan Overseas
2018 87,763 1,258
2019 82,775 1,051
2020 84,828 892

Products and Technologies Contributing to Resolving Problems with the Water Environment

Seawater desalination membranes help to eliminate water shortages

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.

HOLLOSEP® hollow fiber forward osmosis membranes

RO membrane for seawater desalination

RO membrane for seawater desalination

The Toyobo Group’s hollow fiber type reverse-osmosis (RO) membrane element HOLLOSEP® 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.
