It remains the responsibility of the generator of any particular waste to make this hazardous waste determination. However, a steel aerosol can that does not contain a significant amount of liquid (i.e., emptied through puncturing, with a hazardous waste determination made on the drained contents to ensure proper disposal) would meet the definition of scrap metal, and if it is to be recycled, would be exempt from Delaware’s Regulations Governing Hazardous Waste.
Scrap metal that is recycled is exempt from the regulations even if it is hazardous waste, so generators need not make a hazardous waste determination.
Intact used (waste) aerosol cans that are not punctured require a hazardous waste determination.
In short, to properly recycle used aerosol cans as a scrap metal, you should:
Recycling punctured aerosol cans as a scrap metal will help reduce some hazardous waste regulatory requirements, save you money on disposal cost and be beneficial to the environment and the State of Delaware.
