This fairly common process is mentioned in the federal regulations at 40 CFR 260.10 and was incorporated by state regulation. The neutralization procedure involves adjusting the pH level of the corrosive waste so that it has a neutral value of 7. The waste may still be hazardous, however, if it has other characteristic properties, such as ignitability or toxicity. See the state section CHARACTERISTIC WASTE for more information.

Examples of industries that might use neutralization of wastes are automobile industries that use acids for cleaning engine parts that create an acidic corrosive waste, and cleaning industries that use caustics in their operations that create an alkaline corrosive waste.
