Water Stewardship

Water is an important factor in production for food and beverage businesses. OISHI is therefore committed to developing and improving the management of water resources to be more efficient for sustainable growth, as well as reducing the cost of doing business and reducing the risk of shortage of quality water resources in the future. OISHI also complies with regulations and laws and has an international standard system to supervise and verify the accuracy of business operations related to water use, including controlling the discharge standards of wastewater until the quality is better than the determined standard before releasing into natural water sources without affecting key stakeholders. OISHI also set a goal to return water to nature to achieve 100% of the water content in finished products within 2040 according to the water management goal of Thai Beverage Public Company Limited.

In 2022, OISHI manages water efficiently as follows:

In addition, OISHI has started a feasibility study on the use of treated water for treatment by dividing used water into three groups: The Black group is water that, when treated, can be released to the outside according to standards; The Brown group is water that, after being treated, can be reused in various production processes, and; The Yellow group is water that after treatment can be reused for consumption. The company is also looking at ways to reduce water consumption in its production processes, further preparing itself to meet the target.
