To help preserve air and water quality, Nikon not only observes applicable laws and regulations, but has also established its own independent plant standards for management.
Each plant regularly measures pollutants released into the air and water, and inspects equipment such as boilers and waste water processing systems periodically to ensure safety.
"Air & Water Quality Environmental Data for Each Plant (Year ended March 31, 2008)" is shown.
Plants engaged in manufacturing continuously expand and evolve structurally, but since the introduction of the "Environmental Management System" in the year ended March 1999, efforts have been made to promote reuse of process waste water, and reduce water usage by involving all employees in water-saving activities.
