On one end of the Kapitolinski trg there are four containers for different kinds of waste.
- "Papir i Karton" (Paper and cardboard)
- "Plasticna i metalna ambalaža" (Plastic and metal packaging)
- "Staklena ambalaža" (Glass packaging)
- "Preostali otpad" (Residual waste)
Each of the four (rather small looking) containers of the sotkon company are standing on a base, that is hiding a bigger container under the surface.
