Designated waste classification

Enter the liquid's state and measurements to see whether it is designated waste and which kind.

← If it goes out through pipes as wastewater, go back and choose again

The type of designated waste is decided by the same nationwide criteria (Annex 1 of the Enforcement Decree of the Wastes Control Act) regardless of where the site is. That is why this check does not ask for a region.

This checks 11 types of designated waste in Annex 1 that relate to waste liquids. It does not judge facility lists or official test methods, and it is not a final classification.Check one waste liquid at a time. If you collect several liquids separately, enter and check each one on its own.
