TOKYO — Japanese information and communication technology company Fujitsu announced that its plant in Nagano, Japan, has deployed the country’s first wastewater treatment system that enables efficient recovery of copper from industrial wastewater by producing sludge with a high concentrations of copper.

Fujitsu Facilities Limited, which is in charge of managing Fujitsu''s facilities, deployed the new system produced by the Toshiba Corporation, 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 now 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.
