Mirror entry
This waste appears in the List of Waste as both a hazardous and a non-hazardous entry. Which one applies depends on whether the waste actually contains hazardous substances above threshold — you assess the contents, not the name. Check the entry in the EWC code finder to resolve it for your load.
