Effective Use of Resources

Effective Use of Water Resources

We are conserving water in our plants and returning waste water to nature after purifying it to avoid impact on the natural circulation of water.

Enhanced 3Rs for Water to Reduce Water Use

The Suntory Group’s plants use a large amount of water, for example, in cleaning production equipment and cooling, in addition to using it as an ingredient in our products. In order to conserve limited water resources, we intensify our activities to achieve targets toward 2030 of “Reduce water consumption at the Suntory Group plants worldwide by 15%*1” through enforcement of 3Rs for water, ensuring that the minimum amount of water is required (Reduce), water can be used repeatedly (Reuse), and water can be processed and used elsewhere (Recycle).

Applying 3Rs in Water Usage

When selecting equipment and devices in our plants, we follow the "3Rs of Water": Reduce the amount of water as much as possible, Reuse water, and Recycle water through treatment.
A variety of activities related to the 3Rs are being implemented at the Minami Alps Hakushu Water Plant of Suntory Products Ltd. In particular, thanks to our use of a sophisticated "water cascade" recycling process, we are an industry leader in terms of per unit production in relation to the volume of water used.

  • Reuse of water recycled at each stage of cleaning stored in 200 ton tanks

Using Cascades of Water

Water used in the manufacturing process is classified into five grades, including coolant water, cleaning water, ets., based on quality. This technology allows plants to recycle water to be used in subsequent processes, for example, using the highest grade water in the most demanding process, and recycling it for use in a process with less stringent requirements.

Effective Use of Rainwater

Japan is fortunate to have plentiful rainfall, and rainwater is one of our important resources. The Suntory Group accumulates rainwater in tanks for use in watering plants.

Comprehensive Waste Water Management

The Suntory Group established voluntary standards for waste water that are equally or stricter than the legal regulations and manages quality so that we may release waste water in a state as close to nature as possible. Waste water from our plants is first purified using anaerobic waste water treatment facilities* and other equipment before it is released into sewers and rivers. Inspectors use measuring equipment to take daily readings of things like water quality under a constant monitoring regime.
To further stabilize waste treatment facilities in plant in Japan, we are holding regular meeting attended by person in charge of waste water from every plant to improve the level of operation management and system to prevent troubles from 2014.
