Environmental ActivitiesEnvironmental Management

Environmental Management

TOK appropriately identifies risks associated with its production and sales activities, and invests management resources to secure clean environment/health/safety across the life cycle (development/production/consumption/recycling/disposal) of chemical products including photoresists for semiconductors and displays, as well as manufacturing equipment. We also continue improvement initiatives effectively to shape a sustainable society through our business.

Environmental Management Organization

To conduct business activities in line with our environmental policy, we have an organization in which managers of sites and divisions oversee and execute environmental programs under the supervision of department managers. Sites with a particularly large environmental impact have their own environmental committees that submit monthly reports to the department managers.
