Huh. TIL.

Already had the thing for years, I refill the cylinders ‘myself’, and I don’t purchase their syrups so I’ll probably keep using mine.

Good to know though. I’ll defs encourage people to buy 2nd hand and avoid syrups/CO2 from them.

Yes they do.

But as someone who likes my bubbly I can attest that the soda stream cylinders do produce close to 60L of beverage, easily offsetting 150 cans per cylinder.

The cylinders also do not need to be melted down to be refilled.

Recycling them is the least wasteful option. Aluminum is one of the few materials that recycling actually lowers carbon footprint compared to harvesting raw. Melting them down is easy but there’s few practical applications beyond introductory metallurgy.

The real solution is to switch to soda stream and reusable bottles.

edit:

So I ran across this aluminum can Solar Heat Collector just now. There might be some opportunity to repurpose the cans for some use that’s carbon negative in the long term. But probably not feasible without specialized tools or skills.
