Monitoring System
1. Items specified by laws and regulations
In each of its manufacturing operations, KIOXIA deploys automatic analyzers performing around-the-clock monitoring of wastewater and waste gases including nitrogen oxide (NOx), sulfur oxide (SOx), total nitrogen (T-N), total phosphorus (T-P), chemical oxygen demand (COD), suspended solids (SS), fluorine, and power of hydrogen (pH). Other items are monitored by sampling.
2. Analysis Center
We analyze approximately 38,000 items of wastewater and waste gas per year at the Analysis Center in Yokkaichi Plant.

Environmental Preservation System
Environmental Preservation System
To promote environmental preservation activities continually and efficiently, in each manufacturing site of KIOXIA we have established environmental preservation procedures overseen by a General Manager with clearly defined responsibilities and authority. An Environment Management Committee deliberates environmental preservation across the entire spectrum of environmental activities, including environmental management systems, environmental policies and environmental objectives. We have further established a Compliance Committee to supervise and ensure full compliance with all relevant environmental laws and ordinances.

Environmental Plant Audit System
Environmental Plant Audit System
KIOXIA Group audit teams conduct annual environmental audits of its sites based on the following principles: 3 “Zen" approach, 3 “Gen" approach, and visual control (management to watch and show) approach.
Through audits, we promote improvement in compliance with laws and regulations, measurement and management of controlled substances, and the 4S approach (sorting, straightening-up, sanitation, sweeping). These audits target eight facilities, including the legally mandated wastewater treatment facilities.
