In the Republic of Croatia, municipal waste management is regulated by laws and regulations which are in line with all of the EU legislations. Regulation has imposed the goals that must be meet and they are publicly disclosed within the Waste Management Act and the Waste Management Plan of the Republic of Croatia. The main goal of imposed regulation is reducing the total amount of municipal waste and the share of biodegradable component in municipal waste, increasing separate collection and recovery of waste. In the order to monitor the completeness of objectives and level of the improvements in municipal waste management system systematized reports regarding municipal waste have been prepared since 2006. The reports contain data including quantities and composition of municipal waste over the years along with data on separate collection, recovery and disposal by counties. Analysis of collected data can help identifying the main factors that affect all of the above. Factors that have been imposed are population, tourism and the economy (service industries). The goal of this thesis is to revise the quality level of reporting, which includes analysis of the manner and quality of data collection and management, analysis of the government authority, timing of report preparation, changes in reporting etc. Finally, recommendations are given in order to improve the reporting system for municipal waste in Croatia and disclose whether the reports are really relevant for planning better waste management.
