Established as a mining and smelting company, DOWA has been supporting Japan’s economic growth associated with its modernization in the field of non-ferrous metals. It has kept growing by expanding its businesses into new fields that can take advantage of its technologies and experiences.

DOWA’s Strengths

Based on technologies and experiences developed through the mining and smelting business, DOWA operates unique, "Recycling-Oriented Business Model" ranging from the production of metals and the manufacturing of high-value-added materials to the recycling of waste.

Resource recycling

We have combined the waste management of our Environmental Management & Recycling Business with the highly efficient metal recovery technology of our Nonferrous Metals Business to form a smelting and recycling complex. We use a variety of processes to recycle large amounts of metal from materials that are no longer of use to society. Moreover, materials that cannot be recycled are incinerated and transported to landfills to reduce their environmental impact.

Provision of excellent materials and technologies 

The Electronic Materials Business, the Metal Processing Business, and the Heat Treatment Business develop and manufacture high-value-added materials at the top of niche markets primarily composed of metal. With our abundant knowledge and high technological capabilities in fields such as semiconductors, conductive materials, copper rolled products, and surface heat treatment, we have created products and services with large shares in markets that undergo rapid technological innovation, such as automobiles, smartphones, and solar panels
