He might have been pulling your chain:automotive industry engineering told me that antifreeze is OK to dump into the municipal sanitary sewer system.
Antifreeze decomposition products includes acids. Acids break down in the environment but in the vehicle they corrode the cooling system. And while in the engine it can be contaminated with traces of fuel, metal particles, grit, benzene, lead and other things so it can be classed as hazardous waste.
All by itself, it'll break down in the environment over a period of a few weeks. However the crap in used antifreeze may not.
