I know we're supposed to be avoiding plastic, but recycling of both glass and aluminium is very energy intensive.
I wonder which is really best, properly recycled plastic, aluminium or glass? Is plastic still a problem if it is recycled and doesn't end up in the sea?
I've been idly wondering about getting a soda stream (or an old fashioned soda syphon) because I like the occasional fizzy water and I could make tonic for my gin.
But initial research suggests that it's a very expensive way to do it, unless you normally drink absolutely loads - I might buy one or two six packs of 500 ml fizzy water bottles a year and maybe one litre bottle of tonic a week - I used to get the six packs of cans from Waitrose, but they seem to have stopped doing them, so now I'm buying the 1 litre plastic bottles, which works out much cheaper anyway, even if you throw away half the tonic because it has gone flat.
But the reviews of the tonic syrups are not good, I've not been able to find out if they have artificial sweeteners in, which I absolutely detest, and they are very expensive.
To be honest, I think I'll be sticking to the plastic, or at least looking out for canned alternatives - perhaps I should email Waitrose to find out why I can't get my tonic cans any more. I don't want to buy other brands of tonic, because they either have artificial sweeteners in, a lot more sugar, or are far more expensive.
