Ontario group: resins and plastics.

Other polymer waste, plastics that are neither latex nor resin, in Ontario's group of resins & plastics.

Is Ontario 233 hazardous waste?

Not from the code alone. Ontario 233 names the waste stream. Whether the waste is subject waste depends on its hazardous characterization or liquid-industrial status, and on the exclusions. The waste number also needs a primary characterization letter after the 3-digit class.

For subject waste, the generator enters the class-and-letter waste number in the waste details of the Ontario hazardous waste manifest. Ontario’s exclusions and shipment rules apply.

What does Ontario 233 cover?

Other polymer waste. Examples are polymer material outside specification and material discarded from a reactor. Whether it is hazardous is a separate decision under Ontario’s waste rules.

Is other polymer waste Ontario 233 or another class?

CodeWhen it fits
233The stream is other polymer waste.
