Wastewater treatment

It is our obligation as a company that uses water as a raw material to ensure that we return our wastewater to nature in pristine condition. In the Kirin Group, we purify the water that we have finished using to voluntary standards that are stricter than those required by law, before we release it into rivers and sewers.

Wastewater biogas

In our breweries, we have introduced anaerobic treatment facilities to purify the wastewater generated by the production process. Unlike conventional aerobic treatment, anaerobic treatment does not require electricity for aeration. Also, the anaerobic microorganisms generate biogas as a by-product of the treatment process. This biogas, the main component of which is methane, can be utilized in biogas boilers and cogeneration systems. Derived from plant-based raw materials such as malt, biogas is a renewable energy and a CO2-free fuel.

Environmental protection activities in basin regions around production plants

At the various prodution plants of the Kirin Group, we are conducting a range of environmental protection activities, particularly riverside clean-up activities in cooperation with local governments and NGOs.
The Kirin Brewery’s Yokohama Plant, in cooperation with an NPO, Tsurumi River Basin Networking, continues to conduct beautification campaigns at nearby Tsurumi River, Living Species Observation Events, and other events.
Kirin Brewery, Kirin Beverage, Mercian, Kyowa Kirin, and Koiwai Dairy Products are also engaged in local environmental beautification and environmental protection activities, focusing on the rivers they draw water from and other nearby rivers.
In response to the COVID-19 pandemic, a considerable number of our plants canceled river and beach clean-up activities in 2020. In July, however, our Toride Plant took part in coastal cleaning activities along the Kinu and Kokai Rivers, and our Shiga Plant did the same along the Seri River in Taga.
At the Four Roses Distillery in the United States, we participate in neighborhood Salt River cleanup activities.

Coastal clean-up activities

A group of 36 people, consisting of employees of Mercian’s Fujisawa Plant and their families, participated in the 43rd Zero Trash Clean Campaign - Beach Clean Up Kanagawa 2019, a clean-up activity on the Katase Coast in Fujisawa hosted by the Fujisawa City and the Kanagawa Coastal Environmental Foundation on May 26, 2019. The Plant supports the goals of this initiative, namely to “conduct a clean campaign to protect the beautiful natural surrounds of the Katase Coast, so that the beaches can be widely loved as a place of rest and relaxation for all,” and participates in the campaign every year. In 2020, however, these activities were cancelled as a result of the COVID-19 pandemic.
We will continue to widen the circle of volunteers and call on everyone to participate in the beautification of the environment on the Katase Coast.
