I can't tell if this is circular because of the shape, or circular as in "circular economics."

Looks like it's circular as in "circular economics". But that's a pretty tenuous claim -- it also looks like there is no re-use, which seems like it should be an important part of the concept.

Presumably they're just latching onto the buzzword to get some grant funding or qualify for some project requirements or something?
