Water Resource Initiatives
Recognizing that our business activities affect the entire planet and that protecting the global environment is essential for our survival and activity, we actively take the initiative to protect the environment under the Nisshin Seifun Group Environmental Basic Policy, including initiatives to reduce waste and CO2 emissions and to effectively use resources and energy.
We recognize that our business activities are very closely linked to water resources, so we are carrying out initiatives aimed at using these resources effectively, as well as risk assessments.
Within our business activities, the volume of water used in the flour milling business is relatively low, but a certain amount of water is needed for the processed foods business. We are conscious of this issue and under our Environmental Basic Policy, we promote environmental protection such as using water resources effectively, reducing water use volumes, and preventing water pollution.
To address against future water resource shortages, in fiscal 2021 the Nisshin Seifun Group set medium-term targets to be achieved by fiscal 2040. We work for reducing water consumption in our production processes by identifying locations and processes where water can be reduced throughout our group and by reviewing water usage methods.We will also work with our partners at all stages of our supply chain to ensure effective utilization of this finite resource.
Target for fiscal 2040:
- Reduction of the amount of water used in plants per unit of production by 30% compared with the fiscal 2022 level
- * This target applies to group companies in Japan and overseas.
- * We have set targets for each region based on the water supply risk level. We aim to halve the amounts of water used in regions with particularly high water risk levels.
* Specific water withdrawal: Excluding the water that unable to reduce such as by incorporated into products
Overview of water use
We have major production sites in eleven countries, and we monitor the water use volumes and effluent drainage routes of all manufacturing sites in line with Group management standards. In addition to the daily management of water conservation and leakage prevention, we are also working to reduce water use and wastewater per production unit through initiatives such as concentrating production into highly efficient production lines, adjusting our product mix, and carefully planning production. Going forward, we will set targets using appropriate indicators for our Group’s operations in order to making water usage even more effective.
Water use and effluent load
In our flour milling business, we mainly use a dry milling process which uses an extremely small amount of water relative to production volumes.
All our businesses are equipped with wastewater treatment facilities, and we work to perform appropriate management that uses water as effectively as possible.

Taking care with water resource
Since fiscal 2018, we have been using Aqueduct, an evaluation tool developed by the World Resources Institute, to regularly evaluate water stress and water risk at all manufacturing sites in Japan and overseas and in the regions from which we source raw materials.
Scope of evaluations
Primary raw material sourcing regions: Sourcing regions in eight countries including Japan
Group manufacturing sites: 54 in Japan and 34 overseas*
* As of the end of March, 2021
Carrying out water risk evaluations
The results of water risk evaluations have shown that none of our raw material sourcing regions are at extremely high risk. In order to achieve safe and secure procurement, we conduct supplier evaluations based on our own Group standards and maintain regular communication with business partners, including through site inspections.
At our manufacturing sites in China, which have a relatively high level of water risk compared to sites in other countries, we have found that water stress levels are high. As our production at these sites does not require large volumes of water, this is not a major concern at present, but we monitor water use at each site and strive to reduce per unit water use at sites where it is particularly high.
- Water stress: A situation where the demand for water exceeds the available amount during a certain period or where poor quality restricts its use.

Using water resources effectively
We are working to save water by reducing water consumption, raising awareness among employees, and cultivating water-saving mindsets through environmental education. Also, when we need to dispose of wastewater, we strive to effectively use water resources by disposing of this water in ways that minimize environmental impact.
Wastewater treatment equipment that generates clean energy
Wastewater treatment equipment installed at Oriental Yeast Co., Ltd.’s Osaka Plant combines methane fermentation with activated sludge treatment. This wastewater treatment process creates methane gas that can be used as fuel for a biogas engine that generates electricity, thereby reducing the amount of energy consumed by the plant. Furthermore, the sludge produced by this process is used as a fertilizer. This both minimizes the environmental impact of wastewater treatment and reduces the plant’s energy consumption.
ZLD system installation for yeast production plant
Fresh yeast production plant of Oriental Yeast India Pvt. Ltd. (OY India) is located in the suburbs of Pune,Maharashtra, India. That plant does not discharge wastewater outside the plant grounds for installation of zero liquid discharge (ZLD) system.
Dense wastewater will be concentrated and then incinerated in a boiler, while light wastewater will be purified and reused within the plant, ensuring zero liquid discharge from inside the grounds. In addition, sludge generated from processes within the plant will be reused as a raw material for fertilizers. The aim is to limit use of local water resources as much as possible while also reducing the environmental impact of operations.
This initiative is being welcomed by local authorities as a good model for the future.
Protecting water resources
Supporting activities to protect Kiritappu Wetland
Our business and products are dependent on the blessings of nature. We hope that these blessings will continue to be available as a foundation of a healthy and fruitful life for people into the future, so we are supporting activities of the authorized NPO Kiritappu Wetland National Trust, which is working to conserve Kiritappu Wetland in Hokkaido. Kiritappu Wetland is Japan’s third biggest wetland and the trust carries out research activities to understand this abundant ecosystem and its connections to the surrounding area, as well as conserve the upstream areas that provide the wetland with water and the surrounding forest.
Local activities to protect spring water (NBC Meshtec Inc.)
There are many natural springs in the region surrounding NBC Meshtec Inc.’s head office. The annual average discharge of these abundant springs is 14.5 liters per second, thereby providing a habitat for species that can only flourish in fresh streams, such as Japanese freshwater crabs and Semisulcospira Libertina freshwater snails. It is also an important recreational area for the region, where fireflies can be found at the start of summer.
Since its founding, NBC Meshtec has sought to operate its business in a way that can coexist with the bountiful nature of the Musashino area, so NBC Meshtec Inc. works with local communities on activities to preserve these water resources.
