Realizing a Recycle-oriented Society (Effective Use of Resources and Pollution Control)

Approach to the Effective Use of Resources and Pollution Control

Zero-Emission Challenge

The Nippon Koei Group strives to control waste production and save resources in its business activities through waste mitigation, reuse and recycling in an effort to realize a recycle-oriented society which reduces the environmental impact. Our activities actively pursue green procurement, energy savings and other environmental initiatives.

Nippon Koei participates in the Zero-Emission Challenge as a company entrusted with national projects from the Ministry of Economy, Trade and Industry tied to the 39 themes of the Environment Innovation Strategy for technical development, technological adoption, and social implementation.

Specific Initiatives for Effective Use of Resources

R&D Center Initiatives

The R&D center conducts basic and applied research toward practical applications as well as creates designs for civil engineering structures for the purpose of enhancing Nippon Koei technical development capabilities as a consulting engineer. Whether dams, waterways, sewage facilities or sloped drainage along roadways, the R&D Center produces miniatures able to fully reproduce actual phenomena to investigate and propose designs for facilities with optimal geometry according to actual water flow and hydraulic model tests.

This research and development relies on eco-friendly testing as one measure to effectively use resources by recycling test water and reusing acrylic materials in sewage experiments and other such tests.

Fukushima Site

The Fukushima Site develops and manufactures a broad range of electrical equipment from hydroelectric power to power transmission and distribution . Therein, waste reduction initiatives control waste emissions as well as reuse and recycle resources.

Pollution Control Initiatives

Proper Chemical Substance Management and Usage Reductions

Nippon Koei has one of the largest research facilities of a private consultancy where broad technical development is done for everything from waterways, roadways, disaster prevention, and other infrastructure related to environmental protection. Technical development not only includes basic research in anticipation of the future but also applied research and tests into the science and technology supporting Nippon Koei businesses.

As part of these tests and research, we strive to reduce the use and emissions of chemical substances in chemical analyses by incorporating the latest analysis technologies that comply with analytical chemistry standards. Facilities handling hazardous and non-hazardous chemical substances employ all structural elements mandated by the Water Pollution Control Law, such as liquid barriers installed on floors, water-proof coatings to drainage grooves, and structural reforms to ancillary piping. Regular inspections also strive to prevent any chemical leakage from a facility.
