NKK and the Environment

      NKK believes it is the Company's important corporate duty to implement self-imposed controls and make ongoing efforts toward preserving the environment. Accordingly, from the early 1970s the Company has continuously endeavored to maintain a balance with the natural environment by utilizing its technical edge. Not only have we tackled ecological issues in the field of steel production, we have contributed to the development of effective methods for the recycling of industrial waste, preservation of water quality, and the conservation and effective use of energy.

      The Company aims to create a recycling-oriented society that works in cooperation with the local community. NKK is also striving to conduct its operations in a manner which emphasizes corporate activities and environmental conservation.
