According to the revised version of Waste Control Act to enter into force in 2017, Wastes could only be recycledassuming that the use of recycled wastes is safe for the environment and human health by environmental safetyassessment. Even before this revision of the law, inorganic sludges could have been recycled as alternative materialsfor filler and cover materials by mixing with soil. However, in case of inorganic sludge from car-washing facilities,the revised law provides that the waste has to be landfilled. To assess the possibility of recycling this waste, weinvestigate the characteristics of the generation and concentration level of hazardous substances and evaluate the safetyof recycling this material to assess whether this process meets the environmental standards. We obtained a total ofeight sludge samples from car-wash shops, such as those in gas stations, car-repair shops and car-wash facilities. According to the results of leaching tests, most of the samples(8) fell under the detection limit and thus could be legallytreated as general waste. However, in the results of contents some heavy metals, such as hexavalent chromium, lead,copper and zinc, exceeded the standards for soil contamination. We can conclude that the recycling of inorganic sludgefrom car-wash facilities could cause pollution in soil media when recycled and should not be recycled for filler andcover materials.
