The social environment is dramatically changing. Globalization of economy is being accelerated and social expectations of the corporations are increasing more and more.

DOWA advances our business philosophy: To support a high standard of living and contribute to the emergence of a resource-recycling society through globalization of our business. Under this philosophy we are committed to challenge global environmental and energy issues aimed at: promoting recycling by building an global recycling system; developing environmentally friendly products and technologies; promoting mitigation of environmental risks, focusing on waste management and soil remediation.

DOWA was founded in Kosaka-machi, located in the northern part of Akita Prefecture of Japan. We have been engaged in mine development, smelting and refining of metals, working together with people of the town, for 120 years. The gblack ores (complex ores)h excavated here include valuable metals such as precious metals, copper and zinc with impure substances. Kosaka Smelting and Refining Co., Ltd. have grown to be one of the few companies in the world that can process these complex ores. With the backdrop of drastic economic changes and depletion of the ore, DOWA recently has started in the environmental and recycling businesses, using our unique experience.

Recently, global issues such as depletion of resources and environmental pollution caused by improper recycling process has becoming to be serious problems worldwide. We were able to respond to these issues by extracting metals out of various recycled materials containing complex and multiple metals and properly processing them, based on our technologies that enable extraction of metals from complex cores. We also promote collection of recycled materials from other countries in cooperation with their industries and governmental agencies.

This April we launched new smelting and refining facilities in Kosaka that can process both ores and materials for recycling. We invested approximately 12 billion yen into these facilities. We believe that our CSR-corporate social responsibility-is to make gKosakah to be known to the world in cooperation with local communities and administration offices, and spread our philosophy of gBuilding the Resource-recycling Societyh all over the world.
