3.1. Data description

On the basis of the Regulation on waste statistics (EC) No. 2150/2002, amended by Commission Regulation (EU) No. 849/2010, data on the generation and treatment of waste is collected from the Member States. The information on waste treatment is broken down to six treatment types (recovery, incineration with energy recovery, other incineration, disposal on land and land treatment and other disposal). All values are measured in tonnes of waste.

The waste management indicator set aims at showing how much of a country’s or of the EU’s own waste (in the following referred to as national waste) excluding major mineral waste is actually recycled, incinerated (with energy recovery and without), landfilled or backfilled. This means that the waste management indicator should reflect the treatment of national waste, no matter where it takes place, and it should exclude the waste that is imported from non-EU countries. 

Thus for the compilation of a waste management indicator data, which is collected under the Waste Statistic Regulation, is to be adjusted with data for imports and exports from Foreign Trade Statistics. The imports and exports of goods (and wastes) are reported according to the Combined Nomenclature (CN-codes). The data are available from Eurostat's COMEXT database, which includes detailed statistics on the intra- and extra-trading in goods of all EU Member States.  International trade in goods statistics (ITGS) published by Eurostat measures the value and quantity of goods traded between the EU Member States (intra-EU trade) and goods traded by the EU Member States with non-EU countries (extra-EU trade). ‘Goods’ means all movable property.

The CN codes relating to import or export of waste are selected and assigned to one of the treatment types according to the predominant kind of treatment for this kind of waste in the receiving country. A list with these CN codes and their assignment to treatment type is annexed to this Metadatasheet. Member States were asked whether the data and the assignment was plausible. In case of inconsistencies Member States were asked for a different assignment; they could as well provide data, in case it was in their opinion more suitable than the COMEXT data (this was 2010, 2012  and 2014 the case for Denmark, Croatia, Cyprus, Italy, Latvia, Malta, The Netherlands, Portugal, Romania and Slovakia and 2014 for Ireland, see also 14.1).

3.2. Classification system

The data set is broken down into the type of treatment.

Treatment types

On the basis of the treatment operations defined in Annexes 2 a and 2 b of the Directive 2008/98/EC on waste a distinction is made in six treatment types:

Recovery (excluding energy recovery) (RCV_O): operations R2 to R11;

Energy recovery (RCV_E): R1;

Incineration (INC): D10

Disposal on land (DSP_D): D1, D5, D12

Land treatment/release into water (DSP_O): D2, D3, D4, D6, D7

Backfilling (RCV_B)

Only Waste without mineral waste is taken into account (TOT_X_MIN)

The tables are available at national level.

3.3. Coverage - sector

The indicator covers hazardous (hz) and non-hazardous (nh) waste from all economic sectors and from households, including waste from waste treatment (secondary waste) but excluding major mineral wastes  and waste going into pre-treatment activities (like sorting, drying). It covers only waste from final treatment.

The indicator covers all wastes except the following waste categories:

- Mineral waste from construction and demolition (EWC-Stat 12.1)

- Other mineral wastes (12.2,12.3, 12.5)

- Soils (12.6)

- Dredging spoils (12.7).

3.4. Statistical concepts and definitions

Waste: any substance or object which the holder discards or intends or is required to discard.

Trade balance (BAL_TRD): Exports - Imports of waste (EXP - IMP)

Gross Flow (FLOW_GRS): National treated waste (source: env-wastrt)

Net Flow (FLOW_NET): Gross Flow + Trade Balance (FLOW_GRS + BAL_TRD)

3.5. Statistical unit

Amount of waste.

3.6. Statistical population

All waste generated within a country (within EU) and finally treated (within and outside the respective country) excluding major mineral wastes.

10.7. Quality management - documentation

The Member States describe the sources and methods in a quality report. A summary of the quality information at the European level is found in report to the European Parliament and to the Council: quality of waste statistics.

11. Quality management Top
11.1. Quality assurance

The quality assurance is a joint responsibility of the Member States and Eurostat. The Member States conduct the data collection and describe their sources and methods in a quality report (see the link under 10.7). Eurostat can make comparisons over the countries and will discuss the issue of comparability with the countries. Although the concepts, the classifications and the formats are clearly defined, the countries remain free to choose the sources and methods that fit them best. A link to a summary assessment is also found under 10.7.

11.2. Quality management - assessment

See the items 10.7 and 11.1 above.

12. Relevance Top
12.1. Relevance - User Needs

The user needs are defined in the whereas part of the Regulation on waste statistics (EC) No 2150/2002:

Regular Community statistics on the production and management of waste from businesses and private households are required by the Community for monitoring the implementation of waste policy. This creates the basis for monitoring compliance with the principles of maximisation of recovery and safe disposal.

12.2. Relevance - User Satisfaction

No systematic user satisfaction survey was conducted.

12.3. Completeness

The data sets have a high level of completeness. A few data cells are confidential; this concerns mainly smaller countries. Some other data cells are missing because no proper data source was available; the countries concerned are working to make their data more complete.

13. Accuracy Top
13.1. Accuracy - overall

See items 10.7 and 11.1 above.

13.2. Sampling error

Due to the freedom of the countries to choose their methods, sampling methods were used by some countries in some parts of the reporting tables. An overall assessment is not possible, for the assessment at country level look into the documents referred to in 10.7.

13.3. Non-sampling error

Due to the freedom of the countries to choose their methods the non-sampling errors are difficult to summarise at the European level. For the assessment at country level look into the documents referred to in 10.7.

14. Timeliness and punctuality Top
14.1. Timeliness

Within two years after the reference period.

14.2. Punctuality

The Member States have to deliver the data within 18 months after the end of the reference period. Most countries do respect this deadline, some countries deliver with a small delay. In a few cases the delay is over 2 months. In such cases Eurostat will propose an imputation of the country data to be able to produce European totals.

15. Coherence and comparability Top
15.1. Comparability - geographical

Due to the common definitions and classifications the comparability over the countries is fairly high. Some problems remain where countries have not used statistical units to link to the economic activities that generate the waste.

Member States  could as well provide data for waste import and export, in case it was in their opinion more suitable than the COMEXT data (this was 2010,2012  and 2014 the case for  Denmark, Croatia, Cyprus, Italy, Latvia, Malta, The Netherlands, Portugal, Romania and Slovakia and 2014 for Ireland.

In the data the distinction between incineration with and without energy recovery is based on the energy efficiency of the process

15.2. Comparability - over time

The data is comparable over time unless otherwise stated. A break in series flag will be applied to indicate significant changes in methods.

15.3. Coherence - cross domain

As far as possible the same concepts are used for waste statistics.

15.4. Coherence - internal

The data are to a high degree internally coherent (totals are equal to the sum of the breakdowns).

16. Cost and Burden Top

These data create no additional burden on data providers as the calculations are based on data, which is already published in official statistics.

17. Data revision Top
17.1. Data revision - policy

All data are supposed to be final unless indicated as provisional. Correction of errors is possible.

17.2. Data revision - practice

The published data should be regarded as final, unless otherwise stated. Corrections and revisions might occur. Important corrections will be explained in the summary methodology.

Major changes in the methods will be the result of legislation, and therefore announced in the Official Journal of the European Communities.

18. Statistical processing Top
18.1. Source data

The Member States are free to decide on the data collection methods. The general options are: surveys, administrative sources, statistical estimations or some combination of methods. The Member States describe the sources and methods in the quality reports.

18.2. Frequency of data collection

Waste Statistics: Biennial.

COMEXT: Monthly

18.3. Data collection

The original data collection is carried out by the Member States, Eurostat collects the data only indirectly. Member States collect data from administrative sources and in many cases conduct business surveys on waste generation stratified by NACE activity. The survey method and sampling strategy varies from country to country (paper questionnaire, web questionnaire, CATI, etc.).

18.4. Data validation

Eurostat validates national data is done in cooperation with the Member States. All data are approved by the Member States unless the value is indicated as an estimate (flag e).

18.5. Data compilation

The European aggregates are calculated as the simple sum over the Member States.

18.6. Adjustment

Not applicable.

19. Comment Top

Waste Statistics Regulation data is collected by national administrations and covers only waste and waste streams within a country. However, efficient waste management may require the treatment of waste outside the generating country and hence result in the export and import of waste. The reasons for exporting waste are various, e.g.

  • economies of scale. Treatment plants need a minimum waste flow to be operated cost-efficiently. Consequently, it may make more sense for small countries or for border-zone areas to export waste instead of running such plants themselves.
  • market-driven imports and exports of recyclable wastes (metals, paper, plastics, glass). These are often dependant on the existence of the respective industries (metal industry, paper mills, etc.) that are in demand for these materials.

The missing information about exports and imports of waste may lead to a distorted picture when it comes to recycling quotas or landfill quotas. In order to regard such cross border treatment the waste management indicator set (WMI) was developed. The waste management indicator set allows measuring how the waste that is generated in the EU and in Member States is finally treated, in the EU/in MS or abroad.
