CO2 Cylinders and Cartridges

Alternative ways to recycle
Hazardous Waste

Hazardous Waste Collection
CO2 cartridges are hazardous because they are pressurized and they need special handling to avoid toxic exposure for waste workers, the community, and the environment. Even if the cylinder or cartridge seems empty, it could still contain residual amounts of CO2

City Specific Disposal Options
Please check with your city page (residential or commercial) to confirm if additional options are available, such as home collection, drop-off locations, and/or events. (These options vary per city.)

Household Hazardous Waste (HHW) Drop-Off
Your city or county may offer HHW drop-off sites and collection events.
– Los Angeles County: S.A.F.E. Collection Centers and events

Disposal Options For Businesses
Hazardous waste cannot be placed in your containers. Schedule a Special Waste Collection by emailing [email protected] or calling Athens’ Customer Service Department at 888-336-6100. Fees may apply.

Never Dispose of Curbside

CO2 cartridges are hazardous because they are pressurized. Never dispose of them at the curb. Dispose of them as hazardous waste instead.

Keep Away From Heat

A CO2 cartridge is pressurized and may explode if heated, so keep it away from heat and out of direct sunlight in a well-ventilated area.

What Are CO2 Cartridges Used For?

CO2 cartridges add carbonation to drinks like sodas, they propel paintballs from paintball guns, and they inflate bike tires and personal flotation devices in the event of an emergency. They also serve many different industrial purposes for industries such as agriculture, medicine, entertainment, winemaking and more.
