    Pathological waste

Ontario group: plant and animal wastes.

Pathological waste, meaning human or animal tissue, in Ontario's group of plant & animal wastes.

Is Ontario 312 hazardous waste?

Not from the code alone. Ontario 312 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 312 cover?

Pathological material. Examples are human anatomical material, an infected animal carcass, other non-anatomical material infected with a communicable disease, and biological products or vaccines. Whether it is hazardous is a separate decision under Ontario’s waste rules.

Is pathological waste Ontario 312 or another class?

CodeWhen it fits
312The stream is pathological material.
261The waste is a pharmaceutical other than the biologicals or vaccines in pathological waste.

When several characterizations apply, the registration flowchart picks the primary one. The 3-digit class doesn’t replace the flowchart or the exclusions.
