Legal Framework and Waste Classification
- Jul 06, 2018 -

The Alberta User Guide for Waste Managers (Guide) identifies non-empty aerosol cans as hazardous waste depending on the characteristics and percentage by mass of the compressed gases in the aerosol can (Guide, items 45 through 59, Table 4a). Hazardous aerosol cans generally contain inert gases as propellants and corrosive, toxic, or flammable liquids or gases as active ingredients.


Certain conditions under the Waste Control Regulation Schedule 2 keep aerosol cans from being hazardous, specifically:

• Household hazardous waste in the possession of the householder or while unsegregated in a municipal waste management system;

• Agricultural waste resulting from farming; or

• Small quantities of hazardous waste (other than highly hazardous wastes described in Table 4b of the Guide) that are produced in an amount less than 5 kilograms per month if a solid or 5 litres per month if a liquid and the total quantity accumulated does not exceed 5 kilograms or 5 litres at any one time.
