Fujitsu today announced that its plant in Nagano, Japan, has deployed Japan’s first wastewater treatment system that enables efficient recovery of copper from industrial wastewater by producing sludge with a high concentration of copper. Fujitsu Facilities, which is in charge of managing Fujitsu’s facilities, deployed the new system produced by the Toshiba, enabling a high concentration (at least 90%) of copper to be recovered from copper-containing sludge and recycled at a profit while reducing chemicals and other impurities used in the wastewater treatment process.
Moreover, by reducing the types of chemicals used by 75%, the new system places a smaller burden on the environment while reducing operational costs. Additionally, it shortens the processing time required and reduces the amount of space needed for the facility’s wastewater treatment. Fujitsu will undertake tests to verify the effects of the new system while gaining operational know-how, and will consider extending the new system across other Fujitsu Group manufacturing facilities.
