Our CO2 cylinders aren't designed to be thrown away, but they also aren't designed to be traditionally recycled. They're designed to be used until empty, and then sent back to us (or exchanged in-store) for a discount on your new, full cylinder. Find out how to exchange online or in-store. However, if you've come to the end of your Sodastream journey, for whatever reason, please don't throw them away or take them to your local recycling centre. To keep as many cylinders in the Sodastream ecosystem (and not in landfill), we'll send you a £5 discount code to be spent at sodastream.co.uk for every cylinder you return to us - up to £25*.
Upgraded from a blue to pink machine?
Don't throw your old cylinders away! You can exchange blue for pink cylinders online or in-store too.
How it Works
If you have one or more empty blue or pink Sodastream cylinders, simply submit a request here and the team will let you know how to return your cylinders for free to get your discount.
* Discount codes can only be redeemed at sodastream.co.uk - only one discount code can be used per purchase and cannot be used in conjunction with any other discount. The discount codes can only be redeemed against CO2 refills/exchanges, water bottles, flavours, and Sparkling Water Makers. Discount codes are issued at our discretion.
Please note, that if you owe cylinders from Sparkle Savers plan, subscription, or exchanges, then the returned cylinders will be processed against those orders before we can offer discount codes. Discount codes are issued at our discretion.
