This may be a stupid idea, but to my knowledge metals is are some of the best materials when it comes to being easily recyclable.
Ignoring the cost and reusability, wouldn’t recyclable disposable cups made of metal be a better deal than the largely incinerated plastic cups?
Ball (canning jar company) makes them, they are semi-disposable and recyclable.

I wonder what the price difference is between the ball aluminum and the red solo plastic?
Those look cool! Thank you!
