The 3Rs of water resources

Quantity of water used and proper management of waste water

The Sapporo Group conducts appropriate management of the amount of water used and waste water in its water conservation activities. The entire Group will continue its efforts toward protecting precious water resources.

Sapporo Breweries

Along with the 3Rs of water use in the clean/disinfect processes of beer brewing facilities, efforts are being made towards waste water reduction and proper management of waste water quality, based on the laws and regulations of each region.

Status of water reuse

Sapporo Breweries

Sapporo Breweries is making efforts to reduce the quantity of water used by reusing waste water from manufacturing (water used in manufacturing processes) for environmental equipment and machine cooling procedures. The reuse ratio is approximately 3 to 5%.

Introducing the waste water reuse system

From 2000, the Sapporo Breweries Shizuoka factory has installed a system that collects and reuses waste water discharged into rivers, aiming to efficiently use water resources.
The collected waste water is filtered through a reverse osmosis (RO) membrane* to remove impurities and is reused in areas outside of manufacturing, such as supplementary water for cooling towers and wash water for sludge dehydrators. The waste water collected by this system makes up of approximately 10% of all water used in the Shizuoka factory, resulting in efficient use and conservation of water resources.

*RO (Reverse Osmosis) membrane: A type of membrane filter that only allows water through, and has properties that do not let impurities such as ions and saline pass through.

Recycling waste water and kitchen waste water

Waste water and kitchen waste water discharged from the “Yebisu Garden Place” facilities is processed to become recycled water, with decomposition and removal of organic substances using microorganisms through equipment such as the fluidized bed membrane bioreactor. This recycled water is used to water facility greenery or to flush toilets.
