Green Glass Adsorbent Technology is a novel type of heavy metal adsorbent with high efficiency. It is transformed from waste LCD panel glass with ITRI’s patented technique. It features some specific characteristics including high-adsorption capacity; excellent acidic and chemical resistance; recyclable; pretreatment before adsorption is unnecessary; no secondary pollution generates after the adsorption process; adsorbed metal ions can be simply desorbed and recycled. Because heavy metals are extremely hazardous to the environment and organisms, they harm human wellness through the food chain. However, there are some problems or limitations in the current treatments of wastewaters and soils that contain heavy metals, such as high treatment cost, complicated pretreatment, secondary pollution, matrix consideration etc. Due to the excellent metal adsorption characteristics, ITRI’s green glass adsorbent is very suitable for treating wastewaters containing heavy metals including copper, cadmium, nickel, chromium, zinc, lead, arsenic etc.
