Throwing out cent coins doesn’t seem like an environmental waste to you, like throwing out aluminum cans?

Yes they’re impractical to carry and use but does anyone actually do that? Why not do the standard practice of accumulate them in a jar instead of throwing them in the trash like waste?

it’s easy to take them home and throw them in a jar until suddenly the jar is a Kg of metal that can be fed to whatever coinstar like machine is around.

Metals are separated here, but compared to all the other waste I generate, I'd say it's... pennies on the dollar. Storing and collecting things is by itself an expense too: space, energy (you probably store them in a controlled environment), and so on.
