Water is a fundamental resource for the products sold by the Yakult Group, and we consider its sustainable use to be a crucial issue. We promote water recycling and water conservation initiatives at business sites and plants around the world.
Around the world, 2 billion people lack access to safely managed drinking water, while 11% of the global population, or 771 million people, are forced to use limited services, unimproved sources, or surface water

We will reduce water consumption (at dairy product plants in Japan, per production unit) by 10% compared to fiscal 2018 levels by 2030.
The Yakult Group is working to conserve our precious water resources by addressing their effective use and risks.
Wastewater treatment facility
Discharge of appropriately processed water
At Yakult Group plants, water is used not just as a raw material for our products, but also for cleaning and cooling manufacturing equipment and various other purposes.
This section outlines initiatives to use water effectively at Yakult plants.
The Ayutthaya region is blessed with abundant water resources, and our Ayutthaya Plant draws water from two wells. Since the plant is surrounded by paddy fields and other farmland, we have long been conscious of wastewater flows, and are working to eliminate all wastewater flow to rivers. Suspended particles are further removed from treated wastewater using microfilters before it is used to water the grounds and flush toilets. When the plant’s manufacturing tanks were updated, the old tanks were repurposed as wastewater storage containers where water could be reused for cleaning vehicles and other purposes. We also actively communicate information about these initiatives to the local residents.
The Wuxi Plant’s wastewater is reused at other companies’ plants after it has passed through final water treatment locations. We also purify domestic wastewater before it is discharged.
Water used for cooling during production, along with rainwater, is reused to water plants, supply fire hydrants and flush toilets.
We have installed a rainwater collection system which is used to water plants on the surrounding property.
Wastewater which has passed through treatment facilities is reused to water green spaces around the plant. In 2021, we reused a monthly average of 1,413 tons in this way, for a yearly total of 16,956 tons.
