We plan to develop our Environmental Solutions business by fully utilizing the technical expertise of our Steel and Engineering divisions. Working with customers from the design stage, we aim to provide solutions covering a full range of environmental issues and eco-energy needs.
Business Development
In April 2000, we built a center for our Environmental Solutions business. We aim to utilize the Group's full potential and strengths in promoting our eco-business. Technologies and facilities to be incorporated from our Steel Division include our steel operations infrastructure, high-temperature combustion technology, and pioneer technologies for recycling waste plastics into blast furnace feed. Technologies and facilities from our Engineering Division consist of top-class incinerators and water treatment plants, and eco-energies such as wind turbine power generators.
Recycling
— Recycling waste plastics into blast furnace feed —
| |
Waste plastics are recycled and fed into the
Fukuyama Works' blast furnace |
NKK began recycling waste plastics for use as blast furnace feed at its Keihin Works from October 1996. We also began recycling waste plastics at our Fukuyama Works in response to the Container and Packaging Recycling Law, enacted during the period under review. Recycled waste plastics replace the use of cokes as feed for blast furnaces, thereby significantly reducing CO2 emissions. We believe the process will contribute greatly to alleviating global warming. The Mizue system at the Keihin Works is certified as an "eco-town" project by MITI, the Ministry of Health and Welfare and the City of Kawasaki. The recycling system at the Fukuyama Works is subsidized by the Agency of Natural Resources and Energy and NEDO.
