Secure Water Resources

Appropriate Water Management and Water Risks

Water is a vital resource for the Meiji Group, and as an invaluable resource in the world, we believe its management is essential for achieving a sustainable society. Therefore, we set a target to reduce our water consumption by 20% (base unit, compared to FYE March 2016) by FYE March 2031. To achieve this target, we will appropriately manage water intake and discharge as well as mitigate risk, and thereby conserve water and ensure the continuity of our businesses.

Approach

Reduce Water Consumption via Appropriate Water Management and Water Conservation Equipment

We are constantly working hard to save water and reduce its footprint in the environment from our water intake. We have revised our production processes to enhance our water-use efficiency and are also working to recycle water.

Recycling Cooling Water for Reduced Water Usage

The Karuizawa plant operated by Food Segment produces cheese. For years, the plant had used well water in the heat exchangers used to cool cheese ingredients on the cheese production line. This water was used only once, exiting the plant as wastewater. The plant installed chillers through which well water can be circulated and recycled. The new system yields a 16,000m³ annual reduction in water usage at the plant.

Reduced Water Consumption Through Greywater System

KM Biologics has installed greywater* recycling systems in four of its manufacturing buildings at its Kumamoto Production Center. These systems collect recyclable water for primary use from production facilities. This greywater is then used as makeup water in cooling towers. Water discharged from the cooling towers as secondary use water is first filtered and disinfected, and then used in toilets. Overall, approximately 30,000 m³ of water is recycled annually at the Kumamoto Production Center.

Paddy field flooding at KM Biologics Co., Ltd.

KM Biologics Co., Ltd. uses groundwater for production and waterlogs fields (saturate the soil with water) as part of a program to reduce the impact on the environment. We replenish and recharge the groundwater by diverting water from the Shirakawa River nearby and flood the fields with water for about 3 months before planting crops. We have been doing this since 2005 and have been recharging approximately 500 thousand tons of ground water annually, which is more than what is used at the head office and the Kumamoto Plant.

Participation in Groundwater Conservation Group

KM Biologics Co., Ltd. joined the Kumamoto Groundwater Foundation in 2012 to work toward a healthy groundwater environment together with the local community. The Kumamoto Groundwater Foundation is a groundwater environment preservation group that has implemented effective groundwater preservation measures based on research results. As a member of this foundation, we conduct educational activities related to groundwater preservation through participating in groundwater preservation symposia and encouraging employees to purchase water-offset rice, i.e. rice grown in fields that engage in groundwater recharge. During the fiscal year ended March 2020, we contributed an estimated 6,780m³ of water conservation through water-offset rice initiatives.

Improving Wastewater Quality Through Appropriate Chemical Substance Management

We have set more stringent standards for discharged water than the legal standards in Japan, and we are working on preventing water pollution. In order to reduce our environmental footprint of discharged water, we install equipment that uses activated sludge treatment and methane fermentation at plants or for processes that discharge a lot of water.

Independent Practitioner's Assurance of Water Use Volume

In order to improve the reliability of the data, we obtained the indepedent practitioner's assurance for the domestic water use volume of FYE March 2019 indicated on p.43 in the Integrated Report 2019 by Deloitte Tohmatsu Sustainability Co., Ltd.
We work hard to improve the reliability of all environmental data.

Survey of Water Risks

We assess the water risks in all areas where our domestic and international production sites are located in order to understand the impact of water usage on production. For this assessment, we use AQUEDUCT, an international water risk assessment software launched by the World Resources Institute (WRI). We also collect information and develop specific measures for the site.
