Conserving water | Manufacturing

Efforts in manufacturing

The TOTO Group strives to systematically reduce water consumption in manufacturing by identifying water stress by region in production sites and analyzing risks to the local community and business.

Target companies

Scope: TOTO Ltd. and all the 48 domestic and overseas consolidated subsidiaries

Goal

The TOTO Group has established the Global Environmental Action Plan based on the Global Environmental Policy and promotes the reduction of water consumption in manufacturing based on the 12th Global Environmental Action Plan with an activity period covering until FY 2026.

Excerpts from 【 Global Environmental Policy 】

1. The TOTO Group develops water-saving, air-cleaning, and other environmentally friendly products and services and contributes to reducing the load on the global environment.

・The TOTO Group performs an environmental assessment from the stages of research and development and the designing of products and services and carries out activities to reduce the environmental load through all stages from material purchasing to production, distribution, utilization, and disposal (water-saving, air cleaning, energy and resource conservation, controlling of chemicals, etc.).

2. The TOTO Group reduces environmental loads in every process of its business activities.

・In its efforts to reduce the environmental load, the TOTO Group takes action to employ superior technology and materials, conserve resources and energy, reduce waste and packaging materials, recycle materials, and protect the ozone layer and prevent global warming.

・The TOTO Group develops production technologies taking into account environmental conservation to reduce the environmental load during production.

3. The TOTO Group builds an environmental management system for making continuous improvements.

・In addition to complying with environmental laws and regulations, agreements and other requirements, the TOTO Group establishes its own standards to improve the control level and prevent pollution.

Response to water risks

The TOTO Group evaluates water-related risks for sustainable business activities.

We conduct risk assessments for floods and water contaminations and specifically make efforts to grasp the details of water stress (the degree of tightness between water supply and demand) because we believe that it has a strong impact on business continuity.

As a large quantity of water is used in the production processes, we strive to capture water stress of all the production site regiones to lead to effective responses. The evaluation method complies with the GRI (Global Reporting Initiative). We assess the water stress and water depletion of each production site regiones using Aqueduct, which was developed by the World Resources Institute and Water Risk Filter by the World Wildlife Fund (WWF), to identify those under water stress.

Five production site regiones, which are in Mexico, mainland China, India, and Thailand, were assessed as extremely high water stress regiones. We work on investigating further and coming up with measures for those site regiones based on the results.

In response to water Risk, we have assessed each site, selected areas that are less susceptible to flooding, and constructed production plants based on design standards that anticipate emergency situations. In operations, we have installed emergency equipment and conducted training for anticipated situations, and will continue to implement measures going forward.

Measures to Reduce Water Consumption

The global-scale climate change and expanding water demand by population growth have caused serious shortage and depletion of water resources in various regions, possibly leading to an impact on water consumption in our business activities.

The water consumption of the TOTO Group in fiscal 2024 was 1.78 million cubic meters. Focused on the importance of conservation and effective use of water resources, TOTO sets goals for continuous water consumption reduction and has implemented strategic measures to reduce water consumption through water-saving activities and the increased use of recycled water at each business sites.

We have introduced water-saving fixtures at all our bases, strive to conserve water in our production processes, and promote the reduction of water usage.

To further increase water efficiency, our Sanitary ware manufacturing plants recycle wastewater from production at on-site wastewater treatment plants and reuse it in the production process and for Flush toilets. (Head Office, Kokura First Factory, TOTO India Industries Pvt. Ltd., TOTO (Thailand) Co. Ltd., and TOTO Mexico, SA de.CV)

In addition, our Faucet manufacturing plants have introduced a water circulation system that recycles wastewater from the plating process. (TOTO Aquatechno Kokura Plant and TOTO (Dalian) Co., Ltd.)

We will continue to expand the use of Recycling water at each Production factory .
