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?
There is some municipality that is taking this approach. All the restaurants use the same metal cups, and there are return bins around the area. Customers get a drink to go, and return the cup when they’re done. It’s washed and returned to the restaurant.
I’ll have to find a source for this when I’m on my PC, currently on mobile.

Yoo, cool! I’ll have a look, thank you!
