Correct option is (b) False

Explanation: In non-ferrous foundries, dust from the emission control equipment can contain particulates like zinc, lead, nickel, cadmium, and other materials which classified as hazardous waste. But somewhat of materials can be recoverable from this waste, this is done by using filter dust which can allow metal recovery through dust reprocessing.
