Prevention of environmental pollution
As part of our environmental preservation efforts, we are promoting activities to prevent global warming, to reduce environmental impact in our offices and to properly manage chemical substances.
Treatment of Hazardous or Chemical Substances
In construction business, we face various environmental issues caused by hazardous substances, including soil contamination issues caused by heavy metals and chemical substances, and environmental pollutant such as dioxins produced at incineration facilities. We are actively working to implement countermeasures and develop technologies to tackle these issues.
Soil Contamination
Since the enactment of the Soil Contamination Countermeasures Act in 2003, revisions have been made to expand investigative initiatives and to tighten regulations, and new systems have been introduced to manage contamination in waterfront areas and natural and reclaimed land. In light of the above, we take comprehensive approaches from surveys to implementation of countermeasures, including social response measures such as ensuring compliance to related and regulations and seeking agreement among interested parties, as well as development of green construction technologies to minimize impact on the environment.
Dioxin, etc.
We started focusing on the toxicity of dioxins at an early stage and have been working on the development of dioxin remediation technologies. In 2000, we became the first company in Japan to dismantle an incineration facility with dioxin exposure prevention measures, and since then, we have dismantled more than 80 incineration facilities, while properly managing and disposing the waste and contaminated soil generated in the course of the dismantling.
