Statistical Office of Montenegro - MONSTAT as responsible organization for reporting according to the Waste Statistics Regulation for Montenegro delivers following data sets:

• Waste generation by waste category (EWC-Stat Version 4) and economic activities (NACE Rev. 2),
• Waste treatment by recovery and disposal operations and
• Number and capacity of recovery and disposal facilities on national level.
  Montenegro is one statistical region in all three levels which are in accordance with the European statistical standard NUTS.

These data were obtained through the next surveys:

• Survey on municipal waste
• Survey on generated in waste and
• Survey on waste collection and processing.

The data on the number of recovery and disposal treatment facilities and data for number and capacity of landfill sites were obtained from the Survey on number and capacity of waste treatment plants, where the administrative source is Environmental Protection Agency.

Data on waste generation are derived from:

• Survey on municipal waste
• Survey on generated in waste and
• Survey on waste collection and processing

Data on treated waste are derived from:

• Survey on generated in waste and
• Survey on waste collection and processing

The data on the number of recovery and disposal treatment facilities and data for number and capacity of landfill sites were obtained from the Survey on number and capacity of waste treatment, where the administrative source is Environmental Protection Agency of Montenegro. 

Table : Institutions involved in the collection of data and distribution of tasks

Data set 1: waste generation by waste category (EWC-Stat) and economic activities (NACE)

General description of methodology

 The data on waste generation are obtained from following surveys:

• Survey on municipal waste
• Survey on generated in waste and
• Survey on waste collection and processing.

The sources are the businesses (18 NACE groupings) and households which generate waste. The waste types are the 51 waste categories for which data is required under the Waste Statistics Regulation. 

From the generated and from the treated amount of waste, quantities of waste that were internally recycled (processes R2-R11) were excluded.

Determination of waste generation by (sample) survey

 Not applicable, because the surveys were not conducted based on a random sample.

 Not applicable.

This table shows the proportion of waste generation covered by indirect calculation on the basis of waste treatment and how the method is applied.

Row 1 indicates what proportion of waste generation is covered by information concerning waste treatment. This can be done by referring to selected parts of the economy or to selected waste streams. This should be consistent with the table in the concept 3.1.2.

Row 2 identifies the number of waste treatment facilities included in the calculation. The numbers are expected to be equal to the number of facilities in the table in the concept 3.1.8 . Any differences should be explained.

Rows 3 to 4.3 provide a more detailed description of the methods applied. Does the original data set contain quantities of waste classified by the List of waste, by the European waste Classification for Statistics (EWC-Stat) or by a national classification? On what basis is waste which has been treated transformed into waste which has been generated? How are non-specific wastes distributed across sources and how are imported wastes excluded?

Not relevant. 

Estimation of waste generation in the economy on the basis of models or other methods 

This table is similar to the table in the concept 3.1.4 in that it shows the proportion of waste generation covered by other methods and how these methods are applied. Within this table, a distinction is made between methods based on modelling and other methods.

This table focuses on the methods applied in order to estimate the amount of waste generated by households. The various methods are identified in different parts of the table. An important distinction is made between waste generated by households, on the one hand, and waste generated by businesses, i.e. ‘commercial contamination’, on the other.

Determination of treated waste quantities 

From the treated amount of waste, quantities of waste that were internally recycled (processes R2-R12) on the site of their generation were excluded.

This table identifies the number of waste treatment facilities, which are included in or excluded from the compilation of data. There can be several reasons for excluding waste treatment operations: because they treat only internal waste, because they are pre-treatment facilities or because the capacity is below a nationally defined threshold, etc.

This table gives details of the registers used to gather information on waste treatment. 

Not applicable.

The following classifications are used: 

• NACE Rev. 2
• List of waste (LoW)
• The European Statistical Classification of Waste (EWC-Stat)
• Waste recovery operations (Operations R) and waste disposal operations (Operations D).

In Montenegro national version of the standard classification of activities is called KD 2010. KD 2010 entered into force on April 8, 2011 by the Law on Classification of Activities 2010 - KD 2010 ("Official Gazette of Montenegro", No. 18/11, from 01 April 2011). Basic definitions and rules for the implementation of the classification of activities 2010 which is compliant with the definitions and rules for the application of statistical classification of economic activities in the European Union - NACE Rev. 2 (Regulation (EC) No. 1893/2006 of the European Parliament and of the Council of 20 December 2006 establishing the Statistical Classification of Economic Activities NACE Revision 2 and amending Council Regulation (EEC) No 3037/90 as well as certain EC Regulations on specific statistical domains OJ L 393/06) which is applicable in the Member States of the European Union since 1 January 2008. Using the classification of 2010, which substantially and structurally fully corresponds to NACE Rev. 2, it will undoubtedly, provide high quality international comparability of statistical data. Classification provides development and publication of statistics according to economic activities.

The data were collected within the following surveys:

• Survey on municipal waste - within this survey data on public collection and removal of municipal waste, data on source of municipal waste and data on further handling of municipal waste are collecting. In 2022 year 25 units were covered with the survey and the response rate was 100%.
• The Survey on generated waste covers all business entities with 10 and more employees whose main activity is defined in sectors: A – Agriculture, forestry and fishing, B - Mining and quarrying, C - Manufacturing, D - Electricity, gas, steam and air conditioning supply, E - Water supply; sewerage, waste management and remediation activities, F – Construction, G - Wholesale and retail trade; repair of motor vehicles and motorcycles - group 45.2 Maintenance and repair of motor vehicles, M - Professional, scientific and technical activities - division 75 Veterinary activities, Q - Human health and social work activities - classes: 86.10 Hospital activities, 86.21 General medical practice activities, 86.23 Dental practice activities and 86. 90 Other human health activities according to Classification of activities 2010. In 2022 we observed 580 units altogether; the response rate was 81,2%.
• Survey on waste collection and processing included business units which possess permits for waste collection issued by Environmental Protection Agency of Montenegro. In 2022 we observed 96 units; the response rate was 91,7%. 

Survey on number and capacity of waste treatment plants – data are taken from Environmental Protection Agency and response rate was 100%.

Waste is any substance or object which the holder discards or intends to or is required to discard according to Low on waste management ("Official Gazette of Montenegro" No 064/11 from 29 December 2011, 039/16 from 29 June 2016).

Non-hazardous waste is waste whose composition and properties do not have any of the characteristics of hazardous waste.

Hazardous waste is waste containing elements or compounds having one or more of the following hazardous properties: explosiveness, reactivity, flammability, irritability, harmful, toxic, infectious, carcinogenic, corrosiveness, mutagenicity, teratogenicity, eco-toxicity, the property of abrasion and the property of release of toxic gases by chemical or biological reaction and sensitivity / irritability, as well as waste from which, after a delay, other matter may arise that has any of the hazardous properties.

Municipal waste is the waste that appeared in households or during operations which are similar by their characteristics to the waste appeared in households.

Mixed municipal waste is the waste from the household left after separation of some municipal waste fractions for which the possibility of selective collection is envisaged including communal waste packaging.

The landfill site is a permanent site whose primary function is the disposal of waste on or below the surface of the earth, including an internal landfill on which the producer deposits his own waste at the place of origin, except where the waste is being prepared for further transport to the site of processing at other locations and storage places waste before processing with a period of up to three years or waste storage facilities before disposing of it for up to one year.

Waste treatment is the process for obtaining materials or products used as raw materials or the process of preparing waste for production of this material or product in the treatment plant or in a wider manufacturing sense.

Removal of waste is a treatment process that is not processing, even in the event that this procedure results obtaining a substance or energy as a secondary product.

Within the annual survey on municipal waste the observation units are public utility enterprises which the Secretariat for Local Government issued a permit for performance public service of communal waste collection and transportation, and they perform this activity on the whole territory of Montenegro.
Within the annual survey on waste collection and processing the observation units are enterprises engaged in the import, processing or disposal of waste in the reference year, and which have a permit from Environmental Protection Agency.
Within survey on waste generated observation units are business entities with 10 or more employees, whose basic activity is defined in sector: A – Agriculture, forestry and fishing, B - Mining and quarrying, C - Manufacturing, D - Electricity, gas, steam and air conditioning supply, E - Water supply; sewerage, waste management and remediation activities, F – Construction, G - Wholesale and retail trade; repair of motor vehicles and motorcycles - group 45.2 Maintenance and repair of motor vehicles, M - Professional, scientific and technical activities - division 75 Veterinary activities, Q - Human health and social work activities - classes: 86.10 Hospital activities, 86.21 General medical practice activities, 86.23 Dental practice activities and 86. 90 Other human health activities.

Statistical Office of Montenegro - MONSTAT is competent body for the production of official statistics. The Law on Official Statistics and Official Statistical System ("Official Gazette of Montenegro" No 18/12 and 47/19) defines provisions for collection, processing, and dissemination of data. 

Statistical Office of Montenegro - MONSTAT as responsible organization for reporting according to the Waste Statistics Regulation for Montenegro delivers following data sets:

• Waste generation by waste category (EWC-Stat Version 4) and economic activities (NACE Rev. 2),
• Waste treatment by recovery and disposal operations and;
• Number and capacity of recovery and disposal facilities on national level.

Statistical Office of Montenegro was signed the agreement with Environmental Protection Agency of Montenegro in 2011. Base of this agreement the Environmental Protection Agency submits data on number and capacities of waste treatment plants, as well as a list of companies that have been issued permits for waste collection, treatment, and import/export of waste.

Articles 53-60 of the Law on Official Statistics and Official Statistical System ("Official Gazette of Montenegro" No 18/12) provide a framework for protection, use, and transmission of confidential data. MONSTAT has produced two comprehensive rulebooks that cover the procedures for individual data protection as well as keeping individual records. With purpose of the realization of legal framework on functioning of security system and statistical confidentiality there was adopted the Rulebook on keeping statistical data by which manner, time, technical conditions and organization of statistical data storage to prevent their destroying, misappropriation, and unauthorized use is regulated as well as the Rulebook on contents and manner of keeping records on users of individual statistical data by which contents and manner of keeping records on users of individual statistical data is regular. Pursuant to the Article 59, an access to the confidential data is limited to persons performing duties and tasks of official statistical producer and up to the stage the data are necessary for official statistical production. Persons that performs duties and tasks within official statistical producers must sign the statement on respecting the principle of confidentiality. Law on Official Statistics and Official Statistical System is aligned with the Regulation No 223/2009 and the Regulation (EU) 2015/759 from 29 April 2015 that also regulate confidentiality provisions. The Government of Montenegro adopted the Statement on Commitment of Confidence in Official Statistics (Commitment of Confidence).

The Statistical Office of Montenegro has adopted for the implementation of TQM (Total Quality Management) models that encourage the development and improvement of the functioning:

• institutions,
• production of results of official statistics and
• an individual.

In the medium term, the Statistical Office opted for the implementation of the TQM model through the following goals:

1. Strong commitment to users and other stakeholders,
2. Quality statistical processes and products,
3. Professional orientation of employees,
4. Continuous improvements, 

Reducing the burden on reporting units.

Quality for surveys are monitored at all stages of data production (collecting, entering, and processing). Data obtained through surveys are comparing with data from previous years and with data between surveys.

Primary users of the processed statistical data are:

• Environmental Protection Agency of Montenegro for the purpose of monitoring compliance with legislative requirements.
• Ministry of Ecology, Spatial Planning and Urbanism for the purpose of determining the quality of waste legislation.
• Non-governmental organizations.
• Students are also interested for the processed data because of educational purposes e.g. seminar works, diploma paper work, master’s thesis, etc.

Domestic and foreign independent or state research institutions for the purpose of implementing the various studies

The Statistical Office has adopted the Quality Management Strategy, the Guidebook to the Implementation of the Quality Management Strategy, as well as the Plan for the Implementation of the Quality Policy. In order to measure the degree to which fulfills obligations towards users and within the new quality policy, the Statistical Office conducted User satisfaction survey. Data collection was carried out through a web survey, in the period from 1 September to 20 October 2017, while the second survey was conducted in the period from 6 March to 27 April 2020. The results of the survey are available on the Statistical Office website, link:  Monstat website.

Data are obtained by reporting and interview method, so they are subject to the usual types of errors - mistakes in processing and non-response. In order to prevent the occurrence of errors, appropriate actions are taken to identify and eliminate potential sources of error.

Sampling error cannot be calculated because the surveys were not conducted based on a random sample. In survey on generated waste used coverage with threshold (cut-off survey). Observed population are all waste generators that have 10 or more employees. Surveys covers most of the units, which significantly contribute to the total amount of waste generated in Montenegro.

Not relevant.

Non-sampling errors include: coverage error, error of measurement, response error and processing error.

Not available.

Over-coverage units were identified during collection and processing of data and they were eliminated from the central set of data.

See table in the concept 3.1.8.

Not applicable.

All collected data are measured in kilos of waste. In the case that we got data in m³, pieces, liters we apply correction factors. We perform telephone control of the data which is suspected that might indicate wrong measurement unit.

Survey on waste generated in 2022 we observed 580 units altogether - non - response rate was 18.8%. Non-response errors were the reason for weighting of the data within the surveys where we capture respondents with a threshold.

Statistical survey on municipal waste - response rate was 100%.

Regarding Survey on waste collection and processing - non-response rate was 8,3%.

Regarding Survey on number and capacity of waste treatment facilities, the response rate was 100%.

According to the Annual Plan of Official Statistics and Statistical Release Calendar, the deadline for the publication of the Release was 26 October 2023. Data relate to the previous year.

Not relevant because the data published in the first release are also the final.

Time lag of the final results is the number of months from the last day of the reference period to the day of publication of complete and final results. It is expressed as number of months since the last date of the reference period until the date of dissemination of final results (in the form T + n, where n is a number of days or months). T1= dfinl - drefp =10 (T+10). The final data are published 10 months after completed reference period.

Data were published in accordance with the Annual Plan of Official Statistics and Statistical Release Calendar of Statistical Office for 2022.

Data were published in accordance with the Annual Plan of Official Statistics and Statistical Release Calendar of Statistical Office for 2022.

The data are in line with international standards and data are comparable with the EU countries.

Not available.

Data for 2022 are comparable with data from previous years.

The length of comparable time series is calculated by the following formula: CC1 = Jlast - Jfirst + 1 (Jlast - number of the last reference period with disseminated statistics; Jfirst - number of the first reference period with comparable statistics). According to the above formula, the length of the comparable time series  is 12 years. Data are available on the Monstat website in secton data, link: Monstat website.

Considering waste statistic data, we cannot comment on the coherence with foreign trade Statistic because so far we have not made any in depth comparison yet. Within foreign trade statistics there was some data on import and export of waste, but the data was poor.
Statistics on Environment-Economic Accounts not yet developed in Montenegro, so the coherence cannot be made.

See the concept 3.1.1 above.

Basic data source for the survey on waste generation was Business Register. In the Survey on generated waste was used cut-off survey (threshold survey).

For the reporting units were selected business enterprises with 10 and more employees.

From the address lists of reporting units, from the construction sector were excluded companies that are not engaged in carrying out construction works (based on the experience construction department of MONSTAT).

From service activities for the reporting units were selected business enterprises with 10 and more employees, including next classes:

• G 45.2 - Maintenance and repair of motor vehicles
• M 7500 - Veterinary activities
• Q 8610 - Hospital activities
• Q 8621 - General medical practice activities
• Q 8623 - Dental practice activities and and two large exporter of waste.

Generator of waste which on annual level generate more than 200 kg hazardous waste or more than 20 tonnes non-hazardous waste is obliged to make the plan of waste management in accordance with the Low on waste Management (”Off. Gazette of Montenegro”, no. 64/11).

The survey on municipal waste covers services sector and households. Each unit has to report the amounts of waste on the basis of six-digit LoW codes, later converted to EWC Stat. The questionnaire asks for each of the waste amounts to state the following sources:

1. households
2. small enterprises
3. public institutions

Data on generation of household waste are obtained from three surveys:

• Statistical survey on municipal waste, and
• Survey on waste collection and processing -  waste brought to landfill sites by natural persons and
• Survey on generated waste - waste directly exported from original producers.

Data on generated amounts of waste in service activities are obtained by compiling data from different surveys: data on waste generated in service activities (G - Wholesale and retail trade; repair of motor vehicles and motorcycles - group 45.2 Maintenance and repair of motor vehicles, M - Professional, scientific and technical activities - division 75 Veterinary activities, Q - Human health and social work activities - classes: 86.10 Hospital activities, 86.21 General medical practice activities, 86.23 Dental practice activities and 86. 90 Other human health activities) from Survey on generated waste, data on amounts of waste collected by original waste producers from Survey on waste collection and processing and data on collected waste in manufacturing and service activities from Survey on municipal waste.

Environmental Protection Agency of Montenegro collects data according to Annex 2, WStatR, number and capacity of treatment installations, under its responsibility for the licensing of waste treatment operations (Law on Waste Management "Off. Gazette. MNE 64/11").

Data are collected annually, except data on number and capacity of waste treatment plants, which are obtained from the Environmental Protection Agency every other year.

See below.

Data on waste are collected through following surveys: Survey on municipal waste, Survey on waste collection and processing and Survey on generated waste. Reporting method is used for data collection for the Survey on municipal waste and Survey on waste collection and processing, while the data on generated waste are collected through interview method. Data on number and capacity of waste treatment plants are collected through Survey on number and capacity of waste treatment plants where source is Environmental Protection Agency.

The data were obtained from the Survey on number and capacity of waste treatment, where the administrative source is Environmental Protection Agency. 

Data validation is done by comparing data by sectors, years and contacting reporting units. The first stage of validation is visual control of data, then follow logical and mathematical control, outliers control, comparison data by sectors, years, waste code and at the end contacting of reporting units.

This section is about collecting data on capacity of treatment facilities.
