Samsung Display Recovers Silver from Etchant Solutions

Samsung Display said on June 1 that the company recently succeeded in developing technology that extracts and recycles silver from etchant solutions used to etch the surface of display panels.

In June last year, Samsung Display launched the Waste Etchant Recycling Project to develop ways that reduce environmental pollution and create added value.

The company’s research team developed a technology that extracts 99.99 percent silver powder from waste etchant solutions by using sodium chloride and ascorbic acid.

Samsung Display recycles 2.5 tons of silver in waste solutions annually. The extracted silver is recycled as a major material for thin film transistors (TFTs), which improve the picture quality and life span of OLED TVs.
