I am sure emergency workers would rather not have to haul around water in glass containers after a disaster. If you have another material that is cheap, can be injected molded, bends instead of breaking, only impacts humans under mass exposure, and lightweight plesse let people know.
Aluminum is lighter than glass. Cardboard can be treated so that it holds fluid as well (and can still be made recyclable)
Regardless, plastic requires fossil fuels to make. It needs to go.
I have aluminum cups that can be (hand) washed/reused/recycled. Most plastic cannot be recycled
The tech is there, companies just need to be incentivized to use it.
I don't know how the chemistry works, but we had aluminum cups and they were somehow taking the calcium in the water and concentrating it into little deposits on the bottom of the cup which were hard to get off. I switched back to glass.
Alright so go and do it. I have done some plastic extruder machine control systems. Let me know when you need my help. It is pretty crazy to me that there is this really simple solution that no one on earth is trying and there is a shitton of money to be made but it is possible.
Are you missing the point that plastic is used because it is cheaper, not because it is better for humanity and nature?
It's like saying "so go ahead and fix the climate, if fixing the climate is so good for us". What exactly do you think the problem is?
Bronze, but it aint cheap.
Thermoses are commonly used, and they even have a vacuum inside!
If you don't care about keeping the internal temperature, there's a lot of options for good reusable water containers. Why should we even use disposable containers if we can avoid it?
I have a glass water bottle I use daily. I am talking about a specific use case.
silicon?
It is brittle right?
