In waste treatment, soil remediation and recycling, we offer comprehensive services throughout the process that encompasses transportation to controlled landfilling.

Based on technologies it cultivated in mining and smelting, the DOWA group was one of the pioneer enterprises to engage in environmental and recycling businesses in the 1970s. Besides waste treatment, recycling and soil remediation, our strength as part of the one-stop services include transportation of wastes from the generators to the controlled landfill facilities. We also deliver the same level of quality services for our overseas operations, primarily in Asia, on par with our service level in Japan.
