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?
I’m not sure I understand. Are you saying cups are more convenient than cans or bottles?
No, the convenience (for most people) I think is in that they are able to get a drink regardless of planning. As long as they’re in a car, they can get drive trough drinks. No need to have cups ready in the car.
Ah, I see. I think the original comment was saying that there’s no need for a cup- A can is much more convenient, and you don’t need to be carrying a cup already.
