A friend of mine (actually a friend, not me, I have known forever not to buy soda streams I PROMISE I'M NOT A LIB 
) wants to actually try to boycott Israeli products (finally). They have a soda stream though and they want to continue to use it, but they don't want to buy the cartridges from soda stream because they're don't want to support genocide. Since this is a noble goal I want to help them.
So what are their options, where do they buy cartridges for their soda stream that don't support literal genocide. This is their Very Important Treat and they really want their treat and we all deserve our treats so I'm trying to help them. Thank you.
Thanks everyone this was super helpful...looks like you just buy an adapter and then I've got a bunch of local brew stores that will fill the tank!
My parents got an adapter from Amazon that allows them to attach an actual standard CO2 tank, purchased at a local gas company, to the soda machine, which they get refilled every so often. The gas company also refills used SodaStream canisters, so they also get those recharged to use as backups when the standard tank runs low.
It looks like you can buy some kind of adapter for generic CO2 canisters: https://www.theverge.com/23631306/sodastream-bad-deal-west-carbonator-alternative-diy-seltzer-hacks
I have one, with a 10lb tank and the refill on the tank is like 15 bucks. Last refill I got lasted me an entire year, and I use the thing a lot.
I got alternatives at home hardware. It's some Quebec company. The cartridges are way cheaper than sodastream too. However, I've only seen them in the one place, everywhere else only has sodastream cans.
There is no ethical consumption under capitalism. Unless you’re truly going to lead a boycott movement, this isn’t going to make a difference. Anything else was probably made in a sweatshop by the hands of heavily exploited workers. Enjoy your life.
BDS is an organized boycott movement with clear demands and this would be part of that
boycotts are a useful tool in concert with an organized political movement (like BDS or the striking workers at Kellogg's) but can be ultimately counterproductive when simply done as individual purchasing decisions:
In short, a strong belief that ethical consumption will lead to ethical practices is not warranted – purchasing as voting is a weak feedback mechanism at best and there are other actors who are able to influence the system. The danger, however, comes in believing that this mechanism can make substantial political change. Ethical consumption gives the individual the illusion of contributing to progress; of “doing their part” by making purchasing decisions. This illusion can detract, and probably has detracted, from trying to put forward an avowedly political agenda that seeks to mobilise people collectively to make the changes they support. Instead, it individualises ethics, it individualises politics and it reaffirms us as consumers rather than citizens – it is a part of the profit-maximising, pathologically-externalising neoliberal market system that has caused many of the problems ethical consumerism seeks to alleviate, rather than being an alternative.
True, but if there is another option, then it makes sense to try to find it!
No ethical consumption doesn't mean all consumption is equal, it means you'll never manage to reach full ethicality under capitalism. It is not free reign to consume as unethically as you like.
Did I say that? My point is, good luck finding something that is as luxurious as a SodaStream built by anything but heavily exploited hands.
Yeah I don't understand forgoing a $100 sodastream and then paying like $20,000 to the US government
I have a homemade wine supplies shop near me that fills the bottles I already had and gives them back for less than half a replacement. I would assume many such places are equipped to fill CO2 canisters all around the world. I think they also do it at the hardware store.
you can buy CO2 at welding supply shops. much cheaper than soda stream, of course you need to pay the $100 dollar deposit for the cylinder. most shops also have "beverage grade" CO2, which is probably less pure if anything than the regular labeled CO2, both are fine, and will likely give you a tank with a siphon if you ask, which you'll want. If your cylinder doesn't have a siphon, you'll need to hold it above your tank, upside down, which is a minor inconvenience with a 10lb or larger tank..
from there, either get a hose and adapter which connects directly to your soda stream from the cylinder, or some hoses and adapters for filling your existing CO2 tanks. paintball gun tanks can also be used with an adapter, though they'll be wider than the sodastream ones, and might not have the clearance for your machine, or wont let the plastic cover go back on.
Most Soda-stream tanks have an anti-backflow valve, which requires going slowly and carefully to fill up, or replacing the valve and then you can fill it up normally. freeze your tanks before filling, and you'll be able to fill them up more. weigh them while you do it, the cylinders will have a rated weight and tare engraved on the neck.
also, the route with the fewest tools, is to unscrew the valve, and funnel in the appropriate weight of crushed dry ice, and then screw the valve back on. sounds more expensive in the long run, and potentially dangerous.
