10.7. Quality management - documentation
Not available.
11.1. Quality assurance
Statistical Office of the SR has implemented the Quality Management System (QMS) which is based on the International Standardization Organization standard - ISO 9001. The QMS has been certified by the certification body every three years starting with 2006. Respecting the process approach principle and Plan-Do-Check-Act (PDCA) model, the system covers issues related to management, resources, operation and measurement, analysis and improvement. The system has been enhanced by the inclusion of requirements of the European Statistics Code of Practice and of selected elements of other advanced quality management systems. The QMS is described in the Quality manual (only available in Slovak). The application of the quality manual in practice ensures that all activities that have an impact on the quality of statistical products are planned, managed, examined and assessed.
According to our assessment the quality of data on waste for Slovakia is good.
The good quality of waste statistics is ensured by using reliable source data, applying sound methodology for data compilation in compliance with the Waste statistics regulation. Compiled data are checked and validated at the national level and also by Eurostat.
National waste statistics (definitions, concepts, classifications) is harmonized with the EU waste statistics.
Data accuracy and reliability are described in more detail in the concept 13 of the quality report.
12.1. Relevance - User Needs
The key user of data on waste statistics for Slovakia is Eurostat. Another important users of this statistical product are:
at international level - OECD, EEA,
at national level - Ministry of Environment of the SR and its organizations (Slovak Environmental Agency, Slovak Environmental Inspection etc.).
In general, needs and requirements of the users of waste statistics have been met.
12.2. Relevance - User Satisfaction
The customer's satisfaction survey specifically regarding waste statistics is not carried out. In general, feedback of users of waste statistics is positive.

No issues.
13.3.1.6. Coverage of waste treatment facilities and criteria for exclusion
See table in the concept 3.1.8.
Note: Also treatment facilities for HAZ waste are excluded, since most of them carry out waste disposal activities other than landfilling.
13.3.2. Measurement error
Possible inconsistencies identified in data submitted by responding units are usually corrected within the process of data validation.
Waste treatment facilities report capacity data either in tonnes or in litres. Data that are reported in litres are subsequently converted into tonnes.
13.3.3. Non response error
Non response errors are insignificant according our assessment.
13.3.3.1. Unit non-response - rate
The unit non-response rate in both data collections is negligible, since the obligation of responding units to provide data is regulated by national legislation:
statistical survey on municipal waste - obligation of municipalities to submit completed questionnaires is regulated by the Act on State Statistics; unit non-response rate is 0% (all responding units reported data for reference year 2022),
reports on waste generation and treatment submitted by companies - obligation of companies to submit reports is regulated by the Act on Waste; unit non-response rate is not calculated.
13.3.3.2. Item non-response - rate
Not calculated.
13.3.4. Processing error
The collected data are checked for possible errors within the data processing which is performed by experts from the Statistical Office the SR for municipal waste data and by experts from the Ministry of Environment of the SR for data on waste from economic activities. Subsequently the data are compiled in the final outputs. Since the data are obtained by exhaustive surveys no imputation methods are applied.
13.3.5. Model assumption error
Not applicable.
14.1. Timeliness
See sub-concepts below.
14.1.1. Time lag - first result
Not applicable.
14.1.2. Time lag - final result
Time lag between the end of reference period and the availability of the source data on waste statistics is circa 12 months.
Final results - datasets submitted to Eurostat are available 18 months after the end of the reference year.
14.2. Punctuality
The transmission deadline specified in the Waste statistics regulation (T+18) was met.
At national level, data on waste are published on time, in accordance with the schedule.
14.2.1. Punctuality - delivery and publication
Slovakia submitted all 3 datasets (WASTE_GEN, WASTE_TRT, WASTE_FAC) for reference year 2022 to Eurostat on 27 June 2024.
15.1. Comparability - geographical
Datasets for Slovakia are compiled in compliance with the Waste statistics regulation, applying common definitions and classifications, thus comparability with other EU countries is ensured.
Since 2001, the Slovak Catalogue of Waste is harmonized with the European List of Waste and national classification of waste treatment operations is harmonized with the European list of disposal and recovery operations (R and D codes).
15.1.1. Asymmetry for mirror flow statistics - coefficient
Not applicable.
15.2. Comparability - over time
Data for available time period 2004 - 2022 are comparable. The same data sources were used for compiling the data for 2004 - 2022 and there were no significant changes in methodology of collection and processing the source data during that period.
However there is one change (enhancement) in datasets on waste generation and waste treatment for reference years 2020 and 2022 in comparison with previous reference years - inclusion of data on municipal waste from other sources.
15.2.1. Length of comparable time series
2004 - 2022 (data are available biennially).
15.3. Coherence - cross domain
The use of statistical units and the classification of economic activities NACE makes the waste domain coherent with economic statistics.
15.3.1. Coherence - sub annual and annual statistics
Not applicable. Sub-annual waste statistic is not available.
15.3.2. Coherence - National Accounts
Not applicable.
15.4. Coherence - internal
The data are internally coherent (totals are equal to the sum of the breakdowns).
The information on generation of waste can not be directly linked to the information on the treatment of waste. Main reason is that the dataset on waste generation includes all produced waste, whereas the dataset on waste treatment only includes waste treated by final operations (waste recovered, disposed) on the territory of the country.
Statistical survey on municipal waste from municipalities: the survey is optimized; its costs and burden on respondents are reasonable; respondents/municipalities keep records from which they can fill in data into statistical questionnaires rather easily; the statistical survey is conducted in electronic form.
Reports on waste generation and treatment submitted by companies according to the Act on Waste: the data collection poses a relatively heavy reporting burden on companies that have to fulfill also many other reporting obligations in the area of environment (air pollution, water consumption etc.); it is conducted in paper form - data from paper reports submitted by companies is necessary to record into the electronic database, which is time-consuming.

17.1. Data revision - policy
The revision policy regulates the general rules and procedures applied in revisions at the Statistical Office of the SR. In accordance with the revision policy, the reason of the revision is always indicated (incorporation of better quality data, data modification based on more accurate methodology, corrections in source data and calculations etc.).
In case of waste statistics there is no need for national revision policy, since data provided to Eurostat and disseminated at national level are final verified data.
17.2. Data revision - practice
Final verified data are submitted to Eurostat, thus no regular/planned revisions are performed on data on waste.
17.2.1. Data revision - average size
Not calculated.
18.1. Source data
The following source data were used for compiling datasets on waste generation and waste treatment (both datasets WASTE_GEN, WASTE_TRT are based on the same data sources):
source data from the statistical survey on municipal waste from municipalities conducted by the Statistical Office of the SR - for data on municipal waste from municipalities,
source data from reports on waste generation and treatment submitted by companies according to the Act on Waste (gathered in the Waste Information System) - for data on waste from economic activities and data on municipal waste from other sources.
Database on waste treatment facilities managed by the Ministry of Environment of the SR was used as the data source for dataset on facilities (dataset WASTE_FAC). The database contains data from Registration lists of waste treatment facilities.

18.3. Data collection
Statistical survey on municipal waste from municipalities conducted by the Statistical Office of the SR:
Responding units applied: all municipalities of the SR.
Reporting system: annual exhaustive survey on municipalities.
Waste types covered: all waste codes under chapter 20.
a) Total no. of municipalities (population size): 2887, b) No. of municipalities selected for survey: all of them, c) No. of responses used for the calculation of the totals: 100% response rate, d) Factor for weighting: not applicable.
Method applied for the differentiation between the sources household and commercial activities: such differentiation is not estimated.
Population served by a collection scheme for mixed household and similar waste, in %: almost the whole territory of Slovakia is covered by municipal waste collection services.
Template of the statistical questionnaire (ZP 6-01, module 265) used in the statistical survey is attached as annex 1 (see the section for annexes below).
Reports on waste generation and treatment submitted by companiesaccording to the Act on Waste: All companies with production of over 50 kg of HAZ waste or over 1 ton of NON-HAZ waste per year are obliged according to the Act on Waste submit reports to respective District Environmental Offices. Content of reports including methodological notes is specified in Annex II of the Regulation of the Ministry of Environment of the SR No. 366/2015 on obligation to keep records and on reporting obligation. Data from reports are recorded into the Waste Information System - database, which is managed by the Ministry of Environment of the SR.
Template of report on waste is attached as annex 2 (see the section for annexes below).
18.3.1. Description of methods of data collection on capacity of treatment facilities (Dataset FAC: facilities of treatment of waste)
Registration sheets of waste treatment facilities: All authorized waste treatment facilities are obliged according to the Act on Waste to keep registration sheets and submit them to respective District Environmental Offices. Content of registration sheet for landfills is specified in Annex VII and content of registration sheet for waste recovery/disposal facilities in Annex II of the Regulation No. 366/2015 on obligation to keep records and on reporting obligation. The registration sheet contains data on quantities of treated waste (disposed, recovered) and also information on capacity of facilities. Data from registration sheets are recorded into the waste treatment facilities database, which is managed by the Ministry of Environment of the SR.
18.4. Data validation
Validation process for data collected from reports on waste generation and treatment submitted by companies:
Submitted reports are checked for possible errors and inconsistencies - competent persons from the District Environmental Offices check data provided in report and identify the errors. Identified errors/inconsistencies are consulted with concerned responding unit and corrected if necessary.
Data are recorded in the Waste Information System (database) and subsequently experts from the Ministry of Environment of the SR check the database for possible errors.
Data from the database are provided to the Statistical Office of the SR as administrative data. Statistical Office performs additional validation of data - data are compared with previous years at aggregated level for NACE categories, for waste treatment operations.
Validation process for data collected in the statistical survey on municipal waste from municipalities:
Electronic data collection is used for obtaining the data. Data recorded by municipalities in electronic statistical forms are automatically checked (programmed check links/algorithms) and possible errors are identified – blocking errors (submission of electronic form is blocked), significant errors and informative errors.
In cases when municipalities submit completed electronic forms without correcting significant errors, the Statistical Office contacts them and requests correction of data identified as errors or explanation of the outlying values.
Also further additional checks are performed on collected data – comparison with data from previous reference years at aggregated level for regions, for waste types, for waste treatment operations and comparison with other related information.
18.5. Data compilation
The source data described in sub-concept 18.1. were used for compilation of datasets for waste generation and waste treatment. Individual data at the level of companies, municipalities broken down by waste types (6-digit codes) and by waste treatment operations (R, D codes) are available.
Table "Waste generation" was compiled as follows:
Rows: Individual data at the level of 6-digit waste codes were allocated to EWC-Stat categories (broken down by hazardous, non-hazardous) by applying the Table of equivalence included in Annex III of the Waste statistics regulation. Note: Specific national waste code 200308 "Small scale construction and demolition municipal waste" is excluded from reporting.
Columns: Data were allocated into NACE categories on the basis of main economic activity of companies; the company identification number is used for assignment of main economic activity (5-digit NACE code) from the Register of Organizations of the Statistical Office of SR.
Column for households (HH): Reported were data on all municipal waste (household waste + commercial waste), share of household waste is not possible to determine.
Table "Waste treatment" was compiled as follows:
Rows: Individual data at the level of 6-digit waste codes were allocated to EWC-Stat categories (broken down by hazardous, non-hazardous) by applying the Table of equivalence included in Annex III of the Waste statistics regulation. Note: Specific national waste code 200308 "Small scale construction and demolition municipal waste" is excluded from reporting.
Columns: Individual data at the level of R, D codes were allocated to waste treatment categories as follows: RCV_E - R1; DSP_I - D10; RCV_R - R2-R11; RCV_B - national code for backfilling TU; DSP_L - D1, D5, D12; DSP_OTH - D2-D4, D6, D7.
Pre-treatment operations: Codes D8, D9, D13, D14, D15, R12, R13 and specific national codes DO - Delivering to households for final treatment, Z - Waste temporary storage in place of origin are excluded from reporting.
Tables "Recovery and disposal facilities by NUTS 2" (table 1, table 2):

Data on generation and treatment of waste and information on waste treatment facilities according to the Regulation (EC) No 2150/2002 on waste statistics as amended (Waste statistics regulation).
Submitted datasets provide information on generation and treatment of waste and on waste treatment facilities in Slovakia, specifically:
WASTE_GEN_table 1: data on waste generation by waste category (EWC-STAT) and economic activity (NACE); 18 aggregated NACE categories + households
WASTE_TRT_table 1: data on waste treatment by waste category (EWC-STAT) and treatment category (energy recovery, incineration, recycling, backfilling, landfill, other disposal),
WASTE_FAC_table 1: data on number and capacity of recovery and incineration facilities by type of facilities and by NUTS 2 regions,
WASTE_FAC_table 2: information on landfills by NUTS 2 regions.
companies with production over 50 kg of HAZ waste or over 1 ton of NON-HAZ waste per year - for waste produced by economic activities,
all municipalities in Slovakia - for municipal waste.
Dataset on waste generation includes waste generated in Slovakia by companies (statistics covers companies that produce over 50 kg of HAZ waste or over 1 ton of NON-HAZ waste per year) and municipal waste generated by households.
Dataset on waste treatment includes waste treated by final treatment operations (recovery, disposal operations) on the territory of Slovakia.
Datasets on waste generation and waste treatment: data are compiled at national level - Slovakia.
Datasets on waste treatment facilities: data are compiled at regional NUTS2 level (Bratislavský kraj, Západné Slovensko, Stredné Slovensko, Východné Slovensko).

Overall, the accuracy of data on waste statistics for Slovakia is considered to be good. Source data come from reliable national sources (official statistics produced by institutions within the national statistical system - Statistical Office of the SR and Ministry of Environment of the SR).
Before submission to Eurostat the compiled datasets were checked and verified by the Statistical Office of the SR and also by the Ministry of Environment of the SR.
Data sources are described in detail in sub-concept 18.1 and validation of data in sub-concept 18.4 of the quality report.
Data on waste generation and treatment: tonnes (t).
Data on recovery and incineration facilities: number, tonnes per year.
Data on landfills: number, cubic meters.
The source data described in sub-concept 18.1. were used for compilation of datasets for waste generation and waste treatment. Individual data at the level of companies, municipalities broken down by waste types (6-digit codes) and by waste treatment operations (R, D codes) are available.
Table "Waste generation" was compiled as follows:
Rows: Individual data at the level of 6-digit waste codes were allocated to EWC-Stat categories (broken down by hazardous, non-hazardous) by applying the Table of equivalence included in Annex III of the Waste statistics regulation. Note: Specific national waste code 200308 "Small scale construction and demolition municipal waste" is excluded from reporting.
Columns: Data were allocated into NACE categories on the basis of main economic activity of companies; the company identification number is used for assignment of main economic activity (5-digit NACE code) from the Register of Organizations of the Statistical Office of SR.
Column for households (HH): Reported were data on all municipal waste (household waste + commercial waste), share of household waste is not possible to determine.
Table "Waste treatment" was compiled as follows:
Rows: Individual data at the level of 6-digit waste codes were allocated to EWC-Stat categories (broken down by hazardous, non-hazardous) by applying the Table of equivalence included in Annex III of the Waste statistics regulation. Note: Specific national waste code 200308 "Small scale construction and demolition municipal waste" is excluded from reporting.
Columns: Individual data at the level of R, D codes were allocated to waste treatment categories as follows: RCV_E - R1; DSP_I - D10; RCV_R - R2-R11; RCV_B - national code for backfilling TU; DSP_L - D1, D5, D12; DSP_OTH - D2-D4, D6, D7.
Pre-treatment operations: Codes D8, D9, D13, D14, D15, R12, R13 and specific national codes DO - Delivering to households for final treatment, Z - Waste temporary storage in place of origin are excluded from reporting.
Tables "Recovery and disposal facilities by NUTS 2" (table 1, table 2):
Data on recovery and disposal facilities were compiled by experts from the Ministry of Environment of the SR by using information from the national database on waste treatment facilities.
The following source data were used for compiling datasets on waste generation and waste treatment (both datasets WASTE_GEN, WASTE_TRT are based on the same data sources):
source data from the statistical survey on municipal waste from municipalities conducted by the Statistical Office of the SR - for data on municipal waste from municipalities,
source data from reports on waste generation and treatment submitted by companies according to the Act on Waste (gathered in the Waste Information System) - for data on waste from economic activities and data on municipal waste from other sources.
Database on waste treatment facilities managed by the Ministry of Environment of the SR was used as the data source for dataset on facilities (dataset WASTE_FAC). The database contains data from Registration lists of waste treatment facilities.

Datasets for Slovakia are compiled in compliance with the Waste statistics regulation, applying common definitions and classifications, thus comparability with other EU countries is ensured.
Since 2001, the Slovak Catalogue of Waste is harmonized with the European List of Waste and national classification of waste treatment operations is harmonized with the European list of disposal and recovery operations (R and D codes).
Data for available time period 2004 - 2022 are comparable. The same data sources were used for compiling the data for 2004 - 2022 and there were no significant changes in methodology of collection and processing the source data during that period.
However there is one change (enhancement) in datasets on waste generation and waste treatment for reference years 2020 and 2022 in comparison with previous reference years - inclusion of data on municipal waste from other sources.
