Aerosols are generally pressurised cans like deodorant, air freshener or bug sprays.
When empty, they should be placed in the household recycling bin.
Some Civic Amenity Sites also accept aerosola. Check the waste service locator for your local civic amenity site details.
Aerosols are made of metals which can be recycled again and again without losing any of their properties.
Ensure they are completely empty and do not pierce, crush or flatten.
