Citizens are thus allowed to separately dispose packaging waste by type of packaging: paper in the blue container, plastic in yellow, glass in the green container, while the waste that is unusable in the recycling process designed black container. Packaging waste which is separately suspended in the above locations will be collected by a special-purpose vehicle for emptying underground containers, and will be prepared for transport to recycling.

The project is jointly implemented by the Ministry of municipal economy and infrastructure of the Sarajevo Canton, PUC "Rad" Sarajevo and "Ekopak" - the first authorized system operator of packaging and packaging waste, and plans to set up three more underground eco-island in the Sarajevo Canton. The project represents the beginning of a new approach to waste management modeled on successful systems that are being developed in Europe in the past 20 years.
