Europe has laws that recycling companies have to state how much % per weight ends up wherever. They charge you in Germany a deposit of ~15 cent per single use plastic bottle and you have to return it in mint condition in special recycling machines to get that money back. I’ve heard that Austria wants to make that 25 cent over there in 2025 - that’s 30% of what a bottle of water costs in a German Aldi.
Why does anyone buy water in bottles? I mean if you get clean water in a tap its absolutely pointless.
Some places do have truely awful tap water even if it is technically drinkable. I’ve been places where the tap water reeked of sulphur and no filter would take out the taste short of an RO filter. We always had to buy drinking water there. At the same time though we always bought water in gallon jugs rather than the individual bottles.
