Feature II Fostering Rich Forests and Living Creatures

02 Purify Water and Foster Living Creatures.

Plants around marshes and water fronts are known to have a high water purification capacity.

We created habitats for those plants, aquatic creatures, insects and microorganisms inside the premises of DOWA Hightech Co., Ltd. in Honjo City, Saitama and installed the effluent treatment facilities that are friendly to environments to clean water using natural purification capacity. We named these facilities “Bio Palette”, hoping that different flowers are in full bloom in each season throughout the year in these facilities like a colorful pallet of paints. The BOD concentration of effluent passing through the Bio Pallet is reduced from 10 to 20 mg/l to less than 3mg/l, with significantly reduced organic pollution. A wide range of creatures like dragonflies and rice fish gather in the Bio Palette, many insects fly to leaves and flowers there, creating an environmentally friendly place for many creatures.

Many people visited Bio Palette, including the Prefectural Governor and elementary school children, who showed great interests in our purification technology utilizing living creatures. Because Bio Palette is environmentally-friendly and low cost treatment system, we plan to promote Bio Palette as a final effluent treatment technology both in Japan and throughout the world.

We have committed to developing technologies to maximize and stabilize the purification capacity of nature (plants and other living creatures) as Bio Palette relies on this natural capacity.

Now, we try to expand the scope of our activities beyond high technologies. When we see guests visiting Bio Palette enthusiastically or children touching animals and plants, we strongly feel that we should further promote the dissemination of the Bio Palette.

Our Efforts towards Conservation of Biological Diversity in Mine Development

Cooper’s hawk (Accipiter cooperii)

Although non-ferrous metals support our affluent and convenient life style, they have a negative impact on the environment, as mine development requires digging out soils and rock from mountains. As mines are often found in those regions with natural ecological systems having rich biodiversity, environmentally friendly development is expected. We must promote metal recycling in order to effectively utilize limited resources.

The DOWA group is actively promoting utilization of recycled materials such as used home electric appliances as materials for refining; however, the role of natural ores are increasing importance.

The DOWA group is now co-developing the Tizapa Mine (zinc) in Mexico with other companies. In developing the mine, we pay much attention to the ecological system surrounding the mine, including afforestation and recovery of vegetation to conserve natural environments.

Around the Tizapa Mine live a valued species of Cooper's hawks (Accipiter cooperii). We try to protect them by setting up nesting places of small animals for them to eat, putting up notices of NO SHOOTING and PROTECTED, and conduct periodic patrols.
