What is the sign of garbage sorting?

The recyclable garbage icon is a circular triangular arrow, which is simple and clear. It's just that the logo color and line thickness are different.

Other rubbish is also non-recyclable. The icon is also a triangle, but there are only two arrows, with the arrows pointing down.

The icon of kitchen waste consists of a stone, a fishbone and half an egg shell, which is easy to distinguish.

The hazardous waste sign looks like a single leaf seedling at the top and an obvious fork at the bottom.

Correct classification, unlimited use of limited resources.
