Bio-Waste Collection and Treatment, Sofia, Bulgaria

Summary of pilot

The case study selected, can be considered an “urban case study”, since it deals with the System for food waste collection of Sofia Municipality, which is causing odour complaints. Complaints for unpleasant odours are usually received by telephone at Municipal Enterprise for food waste treatment and on site personally, by representatives of the Enterprise, as well as through the Contact Center of Sofia Municipality.

The situation

D-Noses role and aims

The role of D-Noses project is to map and frame the issues related to odour nuisance emitted by processes of food waste collection on the territory of Sofia Municipality.
