ROKI Co., Ltd.: Together with Nature.

Our Global Headquarters was designed in harmony with Nature. Its simple form and positioning were created to blend with the spirited Tenryu River below and the surrounding rolling mountains. We feel this is the perfect symbol of our policy toward preserving the environment.

01Environmental Initiatives

Environmental Declaration  At ROKI Co., Ltd., all employees shall actively promote the effective use of resources, energy, and products to protect the global environment and shall work towards environmental conservation.

Head Office

ROKI Co., Ltd. issued its environmental declaration in 1998. We have established a basic environmental policy and are actively pursuing environmental conservation activities. As a filter specialist, our work in developing eco-friendly automotive parts has been accompanied by a commitment to environmental initiatives that has included countermeasures for pollution control, tighter management of chemical substances, energy conservation, zero emissions, and the conversion to lead- and chrome-free products. We acquired ISO14001 Environmental Management System Certification in March, 2004, and are committed to making further improvements that will involve additional energy savings in plants and sales offices, resource saving measures, reductions in waste and additional pollution controls.

As an example of our efforts, as a corporation, to preserve the environment, we are pursuing an initiative to establish a uniform recycling system. The old uniforms we collect are shredded and can be used as acoustic or heat insulation materials by automobile parts makers or construction companies.
