HOME > ENVIRONMENT > REGULATIONS SYSTEM AND RESULTS

Observance of laws and regulations is a key factor for a company when implementing its business activities. The KDS Group tries hard to prevent violation of laws and regulations from occurring, by making effective use of the Environmental Management System.
Unfortunately, a case of exceeding a standard value set by law and another case of exceeding an internally-set standard value were found in water quality control in 2007.
We took appropriate measures to correct the violation and have confirmed in measurements conducted later that there are no longer any violations.
