Sony Semiconductor Manufacturing Corporation completed an initiative for controlling water consumption at Nagasaki Technology Center, a semiconductor production plant, when it installed a new production line intended to boost production capacity. As one part of this initiative, the center began reusing wastewater for gas detoxification equipment, which renders the gases used in the semiconductor production process harmless. A large quantity of industrial water is needed to eliminate the toxins in such gases, and with the installation of the new production line and additional gas detoxification equipment, the amount of industrial water consumption was set for an increase. In response, the center installed a wastewater recovery system to reuse the wastewater from the gas detoxification equipment, enabling it to recover and reuse about 80% of the water. Moreover, the center began using the system to recover and reuse wastewater from other production equipment, allowing it to significantly limit the increase in industrial water consumption related to increased production.
