To manufacture LCD panels, an enormous amount of pure water is required. Sharp believes that maximum recycling of water should be done to preserve our water resources. At the Kameyama Plant, by constructing a closed system that recovers and reuses all the wastewater from manufacturing processes, the preservation of water resources is being achieved. All water used in manufacturing processes, up to 15,300 tons per day from Plant No. 1, is recovered then processed biologically and physicochemically according to the conditions of the wastewater. The purified water is then ready to be recycled.
