| From our responsibility as company using limited resource, Sumiyoshi Kokan promote internal initiatives for environmental conservation. For instance, we installed water purifying system for sewage through manufacturing process in Sakai Factory. It purifies and returns sewage water to be pure water by taking long time, under the strict treatment to be drained. We intend to install wind power generation next year, and encourage each employee's consciousness to ecological movement such as turning off a vehicle engine when stopped, reducing carbon, and power saving. | ||
