Industrial waste-treatment residue
National reporting N205: the residue must come from an industrial waste treatment or disposal operation.
Is National N205 hazardous waste?
Not from the code alone. N205 is a DCCEEW reporting category that groups waste data nationally. It doesn't make every material with this description hazardous. State and territory rules decide the classification, exclusions and movement duties for a real load.
Enter N205 in the national waste-data category field when reporting under that standard. It isn't a transport certificate. A movement needs the code and record accepted where it starts, plus any required destination consignment authorisation for an interstate controlled load. Apply separate interstate movement controls, because a reporting code gives no state movement classification.
What does National N205 cover?
Residues from treating or disposing of industrial waste go here. National examples are scrubber sludge, ion-exchange residues, treatment sludge, pollution-control residue, digestate, bottom ash and char. What links them is the treatment or disposal operation they came from.
