To those who squeeze single use water bottles (think Aquafina, Dasani, Sam’s Choice, etc.) - WHY? Is gravity not fast enough for you? Do you enjoy the crinkly noise? Why squeeze when it’s literally falling out of the bottle?
In here pretty much every bottle and can for beverages has a deposit included in them. 0,10€ for small (<1l I think) plastic bottles, 0,15€ for cans. They're included in the shelf price and when you bring them back to the recycling you'll get your deposit back. Then the recycling machine crushes all to pallets and they're hauled to a factory which then makes new stuff out of the plastic and aluminium.
No need to throw them away. In here the return rate is >90% and even if you don't care about the few coins it's common to leave the empty bottles on top of or next to a recycling bin where others can pick them up and return.
