These types of cylinders and cartridges are considered household hazardous waste. Never dispose of them curbside because they are pressurized.  Contact the manufacturer or the store where you purchased the item from to see about disposal options.


For SodaStream specifically, here are some options…

  • Local Retailers (i.e., Target) should take back SodaStream cylinders as long as you have a receipt/proof of purchase. They may have the option of an exchange program.  You would not get the deposit back.
  • SodaStream Manufacture – If you purchased your item directly from SodaStream, members of the public and businesses can request a return shipping label from SodaStream directly online. You would need an order number or receipt to get free return shipping. You can get the order number from SodaStream or try the retailer purchased from (i.e., Amazon).


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.

Alternative Ways to Recycle


SodaStream Retail Gas Exchange

If you’re using a SodaStream CO2 cylinder for homemade carbonated beverages, you can exchange it for a new one at any of their retail locations. The store will return empty CO2 cartridges to be cleaned, inspected, and refilled. Find out more.

Ways to Reuse

Refill Your Cylinders

Some CO2 cylinders, such as those for beverage carbonation or paintball, can be refilled. Contact the manufacturer or your closest retailer to find out how.

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.
