Electroplating sludge generated every year contains more than 100,000 tons of hazardous metals in China,and the U.S.Environmental Protection Agency (EPA) estimated about 1.3 million tons of wet electroplating sludge generated a year in the States.A promising strategy has been reported to effectively incorporate metal-containing waste materials into a variety of ceramic products,and our previous studies have successfully carried out to stabilize the simulated copper-laden waste.
