Wastewater

Wastewater treatment

It is our obligation as a company that uses water as a raw material to ensure that our wastewater is returned to nature in pristine condition. In the Kirin Group, the water that we have finished using is purified to voluntary standards that are stricter than those required by law, before being released into rivers and sewers.
In the anaerobic treatment process used to treat wastewater, a biogas, with methane gas as its main constituent, is obtained. This gas is used to generate electricity at boilers and co-generation systems. This is a renewable energy derived from plant-based raw materials, such as malt, so is a CO2-free energy.

Environmental protection activities in basin regions around manufacturing plants

The various manufacturing plants of the Kirin Group are conducting a range of environmental protection activities, particularly riverside clean-up activities in cooperation with local governments and NGOs.
The Kirin Brewery 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 others.
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.

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 in 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.
It will continue to widen the circle of volunteers, to take care not to discard trash and call on everyone to be involved in the beautification of the environment on the Katase Coast.
