Service Features

ISO 14001 Certification

In order to fulfill our corporate social responsibility, CBS has acquired ISO 14001 environmental management certification and optimized cleaning operations to minimize impact on the environment.
Reducing the use of detergents containing surfactants, and active use of alkaline ionized rinse water, helps us to achieve these environmental goals.

CBS Cleaning Staff

Conscientious daily cleaning significantly improves sanitary conditions within our managed facilities. CBS staff members are taught the basics of cleaning operations at the head office training center. Technologies that are rooted in practical applications are learned from the ground up and reinforced with training that enables a detailed response that is ideally suited to the features of each site to which cleaning staff are posted.
