Serbia has developed and implemented a system of permitting of waste management activities and is improving its control over the transboundary movement of waste. In 2013, data were delivered by 106 of 168 companies. Data reported from some companies are still based on estimates, although the Regulation on the methodology for collecting data on the composition and quantities of municipal waste on the territory of the local government unit (OG 61/10) prescribes the methodology for analysing the amount and composition of solid waste in local government areas.
