Recycling and Environmental Services

Protecting the environment and creating a resource-recycling society

Business Overview

The recycling and environmental services business applies techniques and experience accumulated from years of operating mines, smelters and refineries to provide services in two areas, recycling and environmental services.
The recycling business recovers copper, precious metals and other valuable metals from end-of-life home appliances and electronic equipment, as well as from recycled materials such as metal scrap generated by factories. The environmental services business cooperates with Group companies to provide detoxification of industrial waste and to recover valuable metals. Fundamental to both businesses is zero emissions, the concept of not generating any secondary wastes. These businesses are contributing to the creation of a global resource-recycling society aimed at not leaving future generations with an environmental burden.

Environmental Services Business

We are engaged in proper disposal of difficult-to-treat industrial wastes.

Detoxification of Asbestos Waste

Asbestos waste is melted at higher temperature to render it harmless. The slag resulting from the melting process is completely recycled so as to generate no secondary waste.

Detoxification of Low-Level PCB Waste

As the first service provider in Hokkaido to be certified by the Minister of the Environment, we conduct treatment of low-concentration PCB waste.

Zero Emissions

The treatment of industrial waste often results in generation of secondary waste such as incinerator ash or residue, which in most cases is then buried in a final disposal site or other location.
Zero emissions is aimed at industrial waste treatment without resulting in secondary wastes, so as to minimize the environmental burden on the next generation.
In our recycling and environmental services business, we are building recycling systems with the slogan, "never discard, never bury," pursuing zero emission industrial waste treatment and nonferrous metal recycling.

Enhancing our overseas collection network

The Group established a recycled materials collection center in Taiwan in 2010, and started marketing support in the US in 2014. By building up an organization for collection of recycled materials on a worldwide scale, we are actively contributing to the establishment of a global resource-recycling society.
