Sustainable Use of Water Resources
Approach to Sustainable Use of Water Resources
Water is a precious resource that is indispensable to people's lives and various industries.
Kewpie Group uses a lot of water for the agricultural products that are used as raw materials, as well as for washing and cooling during the production process.
To ensure the continuation of our business, we recognize that water is a limited and precious resource, and we are committed to its efficient use and reducing the environmental impact of water intake and discharge.
Water Risk and Water Stress Assessment
To assess the impact of water risks on business operations within Kewpie Group, we use the World Resources Institute's Aqueduct to evaluate water stress (the degree of tightness in water demand).
We assess the risk of flooding and storm surges within Japan using hazard maps, and the risk of flooding and storm surges overseas through Aqueduct.
| Number of plants | Flood risk | Storm surge risk | Water stress | |
|---|---|---|---|---|
| Japan | 65 | 25 | 4 | 0 |
| China | 4 | 1 | 2 | 1 |
| Asia | 4 | 2 | 1 | 2 |
| United States and Europe | 4 | 0 | 0 | 2 |

Efficient Use of Water Resources
Kewpie Group is working to reduce water usage by reviewing manufacturing methods and improving processes to promote efficient water use.
In fiscal year 2025, water usage was 6,938,000m³ for Kewpie Group's domestic production plants and 757,000m³ for its global production plants.
The water usage per ton of production (unit cost) was 9.8m³.
Target: Group domestic production plants
Water Conservation Initiatives
As part of its efforts to create factories that are friendly to people and the environment, Kewpie Group is working to conserve water by introducing an advanced wastewater treatment system.
Use of highly treated water
At Deria Foods Co., Ltd., as part of our water conservation efforts in the production process, we are working to minimize water usage by visualizing and collecting data on water consumption, understanding the current situation, analyzing the causes, and implementing countermeasures.
Furthermore, in the Tokyo metropolitan area business division, we have introduced equipment utilizing membrane treatment (RO) technology to reuse wastewater from our production lines. We regenerate an average of 160 tons of pure water per day from the wastewater, which is used not only for toilets in the processing plant, but also for watering trees, cleaning floors, watering roofs, and cooling outdoor units of air conditioning equipment.
Reverse Osmosis (RO) Filtration Equipment
Effective use of cooling water
At Kewpie Jyozo Co., Ltd., we reduce the amount of cooling water used in vinegar production by not directly discharging the cooling water outside the factory, but instead using it as cooling water at a different temperature range.
Controlling excessive water supply
At Salad Club, Inc., we have reduced water usage by switching from a constant water supply to a water supply only when needed for washing cut vegetables, and by thoroughly managing water usage to prevent excessive water supply.
