Waste containing pyridine is classified as non-halogenated waste.

• A. True
• B. False
• C. Not sure
• D. Not applicable

Answer: (A)

Halogenated versus non-halogenated waste is defined by the presence of halogen atoms (chlorine, fluorine, bromine, iodine) in the waste. Pyridine has a six-member ring with one nitrogen atom and no halogen atoms. Therefore waste containing pyridine by itself does not include halogens and is classified as non-halogenated. Only if the waste includes halogenated derivatives or other halogen-containing compounds would it be considered halogenated waste. So, the statement is true.
