Hsinchu Site adjusted control logic through machines and updated old motors to enhance the operating efficiency of pure, recycled and waste water systems.
Yangzhou Site integrated the layout of the water drainage network in the park into a comprehensive monitoring system for the purpose of obtaining the required information on the water quality and volume of water consumption points through integrated data, so as to establish the most reasonable recovery plans with least secondary pollution.
Recycled RO concentrated water, renewable wastewater, process rinsing wastewater, process hot water, and hot water for employees' dormitories have been used for filter backwashing, toilets, refilling the pure water system, and fire safety equipment in the park. In addition, 40~50 ℃ recycled water can be used to recover residual heat so that the cost for heating water can be saved.
In order to continuously improve customer service satisfaction and increase product reuse, E Ink provides return and repair services for ePaper module products sold. In 2022, the total area of Return Merchandise Authorization (RMA) products at E Ink was 5.9 metric tons, and the product reuse rate after repair reached 55.5%. The RMA or take-back program did not create financial benefit since it generated costs. Furthermore, E Ink will continue to research relevant technical processes and further overcome product repair technology bottlenecks to increase RMA reuse rate.
