In 2008, the trend of reducing annual quantities of deposited waste continued both in landfills that are part of public infrastructure as well in landfills operated by the industry. In 2008, 835.3 thousand tonnes of waste were deposited on landfills belonging to public infrastructure and 207.8 thousand tonnes were deposited on landfills operated by industry.
This indicator shows the quantity and structure of waste deposited at legally operating landfills in Slovenia. It outlines the quantity and structure of non-hazardous municipal waste deposited in public infrastructure landfills as well as the quantity and structure of waste deposited in industry-operated landfills.
According to the Environment Protection Act, waste is defined as any substance or item which is discarded, going to be discarded or must be discarded by its owner, producer or any other person in possession of the substance or item. Each type of waste is defined by a six-digit classification number, i.e. a code from the classification catalogue. The waste classification catalogue is published as Annex No. 7 to the Decree on waste management (Official Gazette of the Republic of Slovenia, No. 34/08). Hazardous waste that is marked with an asterisk next to the classification number has one or more hazardous characteristics defined in the framework regulation on waste management. According to the legislation, non-hazardous waste is defined as any waste that has not been classified as hazardous waste. Inert waste, as defined by the regulation on the landfilling of waste; however, is defined as any waste that will not undergo significant physical, chemical or biological modifications, will not decompose, is not flammable, biodegradable or otherwise chemically or physically reactive, does not present a health risk and does not affect other substances if it comes in contact with them in such a manner that may increase the burden on the environment.
Landfilling, i.e. the process of waste disposal, is appropriate as the final treatment of waste that cannot be recovered or otherwise utilized. Various types of waste shall be deposited in appropriate landfills. In compliance with the regulation on landfilling of waste, landfill types are defined as: hazardous waste landfills, non-hazardous waste landfills and inert waste landfills.
A landfill is defined as a site of one or several facilities for the disposal of waste onto or into the ground (i.e. underground). A landfill is also deemed to be any facility or site, or part thereof, used by the producer of waste for the storage of waste at the place of production for more than three years before depositing the waste for further recovery in compliance with the relevant waste management regulations. A landfill may further be any facility or site, or part thereof, used for temporary storage of waste for more than a year before depositing the waste for further disposal in compliance with the relevant waste management regulations.
Municipal waste, i.e. mechanically and biologically treated municipal waste, non-hazardous waste and processed non-hazardous waste with high content of biodegradable substances, as well as stable and non-reactive hazardous waste with pollution parameters not exceeding the pollution limits specified for each type of waste in the waste landfilling regulation, may be deposited in landfills for non-hazardous waste. Landfills for hazardous waste and for inert waste may only be used for deposition of waste not exceeding the parameter limits specified in the regulation on landfilling of hazardous and inert waste, respectively.
Landfilling of municipal waste, i.e. waste from households and other waste of similar origin and composition, falls within the competence of municipal public utility services and is permitted in non-hazardous waste landfills that are local public utility facilities and/or public infrastructure facilities.
In addition to landfilling on local public utility facilities, non-municipal waste may also be deposited in landfills operated by legal entities or sole proprietors. These operators are responsible for active or inactive landfills or underground storage sites that they manage in compliance with regulations.

· Reduction of deposited quantities of waste, especially biodegradable waste.
Data for Slovenia
Objectives summarized by: Environment Protection Act (Official Gazette of the Republic of Slovenia, No. 39/06, as amended) and from the Operational Programme on waste deposition aiming at the reduction of deposited quantities of biodegradable waste for the 2009-2010 period.

Data acquisition date for this indicator: 22 June 2010
Methodology and frequency of data collection for the indicator: The Ministry of the Environment and Spatial Planning – Environmental Agency of the Republic of Slovenia, has been monitoring the quantity of deposited waste since 2001. Landfill operators first reported on the quantity of landfilled waste for the year 2000. Data have been collected on the basis of the Decree on the waste disposal tax (Official Gazette of the Republic of Slovenia, Nos. 70/01, 09/04) and/or on the basis of the Decree on environmental tax for environmental pollution caused by waste disposal (Official Gazette of the Republic of Slovenia, Nos. 129/04, 68/05, 26/06, 132/06 ,71/07 and 85/08), and on the basis of Decree on the landfill of waste (Official Gazette of the Republic of Slovenia, Nos. 32/06, 98/07, 62/08 and 53/09). The Decree on environmental tax provides that landfill operators liable for payment of waste disposal or environmental tax are obliged no later than by 31 March of the current year to submit data on types and quantities of waste deposited in the past calendar year on the prescribed form. The form is attached to the Rules on the form and content of tax return for the waste disposal tax, published in the Official Gazette of the Republic of Slovenia, No. 05/03. Data submitted by individual taxpayers are gathered on the basis of the records they are obliged to keep in accordance with the regulation on waste management or the regulation on the landfill of waste, respectively. These data are then entered into the Waste Management database. Data are available for the period 2000-2008.
The Statistical Office of the Republic of Slovenia acquires data on public collection and removal of municipal waste, the origin and further treatment of the collected quantities of waste by statistical research of annual reports on collected municipal waste (Form KO-Z). By statistical research of annual reports on quantities of waste brought to landfills (Form KO-U), they collect data on number and location of public landfills and capacity. Data are available for the period 2000-2008. Until 2005 were data recorded only for the landfills, which are public infrastructure (municipal landfill sites). The Statistical Office of the Republic of Slovenia updates the data on public removal and landfill of waste, every year at the end of September, while the data on waste brought to landfills including their origin, recovery and disposal are updated every year at the end of May.
