Production of data (including construction and demolition, industrial and commercial and household) and quality report aspects for Scotland.

Production of estimates for UK forestry wastes.

The data set has been compiled from a variety of different data sources from each of the four countries which make up the UK. Due to the vast number of source it is not feasible to describe each in full detail in this report. England makes up 84% of the UK by population and accounts for around 85% of primary waste generated. As a consequence, the methods used in England will have most impact on the final results.

The key data sources for waste generation are:

• Mandatory returns from all facilities with a waste permit.
• Administrative data on all Local Authority Collected Waste.
• Re-gross of historic sample surveys for industrial and commercial waste and construction and demolition waste (Wales only - see Section 8.2).
• Data from other public sector organisations (e.g. Cefas, Department for Transport, Forestry Commission).

Continuity of the main data sources is thought to be good across the UK.  Much of the critical data comes from returns from waste treatment facilities which are permitted in keeping with The Environmental Permitting Regulations 2010, which are expected to continue and to provide annual data.  Local Authority collection data is currently seen as a high priority area in Defra and the Welsh Government and there is a legal requirement on Local Authorities to provide data.  Scotland has similar regulations covering permitting of sites that submit waste returns.  The Zero Waste Scotland aggregates directory is dependent on continued funding, and SEPA are considering legislative alternatives to obtain this data.  NI anticipate that data returns from waste management facilities will continue to be mandatory, similar to previous years. 

No sample surveys were used to estimate waste generation for WStatR 2018. 

Wales determined Industrial & Commercial waste generation by (sample) survey as outlined in Section 8.2

All UK: Secondary waste for columns E38 and G4677 of the generation template is taken from site returns of waste leaving permitted waste treatment facilities. 

All waste removed from 'treatment' sites is mapped to NACE E38.

All waste removed from Metal Recycling Sites is mapped to NACE G4677.

UK: The only estimates based on waste collection are for waste from households, which is described in detail in table 8 below.

Centre for Environment, Fisheries and Aquaculture Science (CEFAS).

There were no projects on the Cefas register without data for 2018, so there were no  estimates.

England: Sewage sludge (E36_37_39, Common sludges)

Following the Eurostat project in late 2014/early 2015 to synchronise sewage datasets, it was agreed that this cell should be completed using final figures from the UWWT (Urban Waste Water Treatment) return.  This return is completed by the Environment agencies of the UK with reference to returns by water companies.  The administrative data reported on tonnages of sewage sludge (in dry weight) sent to different types of treatment outlets in 2018.  See also table 4.

Environment Agency collections from water companies.

UK (except Scotland): Determination of Waste Generated by Offshore Operations.  This covers a range of waste types in small tonnages.  All of the tonnages from this exercise are allocated to NACE B (Mining) as this seems closest to oil extraction which is the main source of these wastes.

Data is collected annually on a voluntary basis through an on-line reporting system known as the Environmental Emissions Management System (EEMS)^[1].  EEMS is the environmental database of the UK Oil & Gas industry and has been in existence since 1992. It provides measured and calculated data relating to emissions from offshore installations and associated onshore terminals, including data on waste generation.  All oil and gas operators in the UK report data through EEMS and as they are all covered by an Environmental Management System the quality of the data is expected to be good.

Industrial effluent sludges were converted from wet weight to dry by multiplying by a factor of 0.27, in line with wet/dry ratios used in previous returns.  Wastes described as ‘hazardous water’ were not reported at all as the dry weight was deemed to be negligible.

In Scotland, offshort waste was determined as part of the C&I dataset (for details see methodology at https://www.sepa.org.uk/environment/waste/waste-data/waste-data-reporting/waste-data-for-scotland/).  In this method, the waste source is determined by the geographic waste origin , inlcuding "offshore" origin, specified in the licensed waste site return.

 Information has been collected in each country through a web based quarterly reporting system (WasteDataFlow – https://www.wastedataflow.org/). The system has been used across all parts of the UK since 2006.

In England there are 345 local authorities (municipalities) of which:

• 222 are collection authorities, responsible for collecting waste
• 31 waste disposal authorities, responsible for managing and disposing of wastes collected by waste collection authorities and for provision of civic amenity sites to which households may take their waste for disposal or recycling
• 92 unitary authorities which combine waste collection and disposal roles in one body

Waste reported as generated by households (EP_HH column) is synchronised to the figure submitted to WFD.

England: Each Local Authority data provider reports data as household or commercial at collection. Waste going to treatment is not split between household and commerical by the data provider, therefore factors are applied to estimate the split.  

For ELVs, a total ELV generation figure is estimated for all sources.  This is based on tonnages of ELVs received at metal recycling sites, with deductions made for tonnages that are also removed from sites, to remove assumed double-counting. It is not possible to accurately differentiate between household and non-household ELVs and so all are reported as NACE G-U_X_G4677 (Services), apart from small tonnages of bicycles that are captured in the household column.

 Identification of relevant treatment facilities: All waste treatment, recovery and disposal facilities in the UK are required to operate under an environmental permit or exemption issued by the relevant environment agency or local authority. Legislation requires relevant agencies to hold public registers of permitted and exempt facilities.  This data is held by each relevant environment agency and is believed to be complete.  From these registers, the number and type of all permitted waste treatment, recovery and disposal facilities has been extracted. 

Exemptions are issued for processes where the expectation of pollution is seen to be of a lower risk or is dealt with by other legislative controls.  They do not include incineration or landfilling activities, both of which would be strictly covered by full permits.  The number of sites operating under exemption have not been included in the infrastructure template.  From the register of exemptions it is difficult to determine individual and non-duplicated sites and in particular it is thought that a significant but unknown proportion of sites are registered but not used.  The number of registered exemptions is huge (~500,000 on ~100,000 sites) so to include potentially exaggerated numbers of genuine active sites would undermine the accurate reporting of the much lower numbers of permitted facilities.

In addition to EA permitted incinerators, there are approximately 100 small scale Local Authority PPC permitted incinerators.  The data on these was not sufficient to report their location, capacity or detail the waste treated by them, so they have been excluded entirely from the report.  A previous investigation suggested that the PPC incinerators treat approximately 1% of the tonnage incinerated in fully permitted facilities in England.

How are the data on treated quantities collected? UK data on treated quantities for recovery, incineration and disposal are primarily taken from returns based on waste management permit systems described above.  The table 11 below provides more details of the methods used

In England and Wales, returns from waste treatment facilities, accredited packaging re-processors and modelled estimates for construction waste were used to provide data for recovery processes. 

In Scotland, the treated quantities came primarily from permit based returns, primarily licenced site returns and waste exemptions. Data on all waste materials (packaging and non-packaging) recycled by accredited re-processors have also been reported. 

In Northern Ireland the treated quantities came primarily from permit and licence based site returns and some from waste exemptions. No estimates were made for exemptions in which a data return was not received in 2018.

How are the data on number and capacity of treatment facilities collected? Data on the annual capacity for waste management facilities operating under a waste management permit was collected from the site permits.  Capacity information for recovery operations other than energy recovery was not required for 2018.

(i)             England & Wales

The level of remaining landfill voidspace in England & Wales at the end of 2018 was provided by operators to the Environment Agency and Natural Resources Wales in 2019. For explanatory purposes ‘landfill capacity’ is defined as: site capacity with both a planning consent and an environmental permit (including void that was still to be created under a mineral extraction permission if the area was permitted), and included engineering surcharge (doming), daily cover and restoration materials. In Wales, some ‘non-hazardous’ landfills may have permitted ‘hazardous’ cells and thus some additional ‘hazardous’ waste capacity than reported

Annual incineration capacity was obtained from permits and checked to ensure it was up to date. Data on local authority registered incinerators (LAPPC) permitted under Part B of the PPC Regulations was produced for England from the Local Air Pollution Control (LAPC) Defra survey. Capacity was estimated to be the midpoint of the assumed minimum and maximum throughput for each facility type.

In England, permit types have been assessed and classified to allow those used for final rather than intermediate treatment to be isolated. 

 (ii)            Scotland

Data on the annual capacity for waste management treatment facilities operating under a PPC permit and WML was collected from the site’s permit or licence.  The data on remaining void space for landfills is collected annually from landfill operators via the licensed/permitted site return form.  Sites that did not submit the returns were contacted directly in order to obtain the information.

(iii)           Northern Ireland

The data on remaining void space for landfills was collected annually from landfill operators via annual reports due under their permits.

The data on capacities of Energy Recovery and Incineration (R1 / D10) were calculated from the maximum annual throughput allowed under the permits

All waste incineration facilities (R1) in the UK are required to operate under an environmental permit issued by the relevant environment agency.  The environment agencies supplied the number of incineration facilities based on the permits they had issued.

 All waste incineration facilities (D10) in the UK are required to operate under an environmental permit issued by the relevant environment agency. The environment agencies supplied the number of incineration facilities based on the permits they had issued. 

For England, Wales and Northern Ireland, smaller incinerators are required to operate under an environmental permit issued by the relevant local authority.  Data on these incinerators was not available and no estimate has been made.

 For England and Wales, backfilling was equated with 'Use of Waste' and 'Deposit for Recovery' operations.  All of these types of facilities in  England and Wales are required to operate under an environmental permit issued by the relevant environment agency. The environment agencies supplied the number of facilities based on the permits they had issued. 

In Scotland and Northern Ireland, waste recovered by backfilling was equated to operations licensed under relevant complex exemptions.  The number of facilities was taken from the annual returns made in respect of these exemptions. 

This is not applicable to almost all of the data submitted as no sample surveys were conducted for 2014 WStatR.

Wales undertook surveys of commercial & industrial waste generated in 2018 and construction & demolition waste generated in 2012.  Construction & demolition 2018 estimates were based on the results of the 2012 surveys.  Most business sectors were surveyed with the exception of: 

Businesses involved in agriculture, forestry & fishing mining and quarrying. 

Businesses involved in waste management and recycling (to avoid potential double counting)

The methodology was broadly similar for each survey – for example each uses the National Inter Departmental Business Register (IDBR) and Local Units for sampling, stratified by employment size and industry category. Published survey reports along with detailed sampling strategies are available online: https://naturalresources.wales/our-evidence-and-reports/waste-reports/?lang=en

Description of the method(s) applied to reach 100% coverage:

The data have been compiled from a variety of different data sources from each of the four countries which make up the UK. Where data are not directly collected, estimates have been made with the intention of achieving 100% coverage.  In total, about a dozen separate estimation processes are combined for each of the four countries in the UK.  Extra efforts have been made for WStatR 2014 to identify and remove double counting where these processes overlap.  In England, initiatives are being undertaken to improve understanding of waste systems which should improve the accuracy of coverage further for future WStatR returns.

Data for Set 2 (waste treatment) on incineration, recovery and disposal quantities are primarily taken from returns based on permit systems. Waste treatment facilities have only been excluded here if they are not considered to be within scope of the reporting i.e. they are storage, transfer, intermediate, pre-treatment activities, subject to the following comments:

• Certain facilities (either permitted sites or sites exempt from waste management permitting) were excluded because they were considered to be primarily intermediate activities and the outputs would be transferred for final recovery or disposal. It is possible that there may also be an element of recovery at these facilities but, because of the methodology adopted, the tonnages concerned will be excluded from the recovery tonnage figures.
• As noted in 4.3., some waste is treated in England and Northern Ireland by methods exempt from permitting and therefore any reporting of the tonnages of throughput.  Estimates for waste treated by methods exempt from permitting have been included but these are subject to extremely high levels of uncertainty.
• Waste accepting sites whose main activities are not part of Chapter 5 of Schedule 1 of The Pollution Prevention and Control (Scotland) Regulations 2000, the Waste (Scotland) Regulations 2011, or the Zero Waste Scotland Aggregate Directory, or are not registered as packaging waste accredited re-processors, have not been identified as they are not classified as waste management activities. Further investigations are being undertaken to identify other installations that accept waste as part of their activities (e.g. foundries, rendering plants) for future datasets. All installations that are not registered as packaging waste accredited re-processors in England and Wales have also not been identified.  Work will be done to address this for future reporting.
• Similarly for England, reprocessors do not operate under waste permits and therefore do no have to make mandatory returns.  Reprocessing of all packaging produced by obligated (above a lower threshold) packaging producers is included as are voluntary returns from some reprocessors with limited coverage.

The amount of recovered material & residual waste collected from non-Household sources in the municipal waste collected by local authorities (LACMW) is declared by local authorities in the UK in their quarterly submissions of data into ‘WasteDataFlow’, the UK local authority municipal waste data portal. From 2014, special effort has been made to ensure that the figure reported in the EP_HH column of the generation template consists only of the 'Waste from Households' measure reported to Eurostat under the Waste Framework Directive.

In Northern Ireland the local authority may collect non-Household waste via an individual round i.e. separately to that of the Household waste, in which case the tonnage of non-Household waste is known. Alternatively this waste may be co-collected with Household waste, in which case the local authority makes a local estimate each quarter.

In England, prior to 2018, it was not possible to separate co-mingled waste collected exclusively from households (as opposed to commercial) into individual waste types (e.g. glass, plastic, metal).  Therefore the total tonnage, prior to 2018, for co-mingled waste collected has been recorded on the generation template as 'Mixed and undifferentiated materials'. For 2018 the co-mingled recylates collected exclusively from households have been separated into the individual materials using proportions derived from composition waste studies carried out by WRAP (Waste and Resources Action Programme). We are currently awaiting similar composition estimates for earlier years – we intend to makerevisions to the 2010,2012, 2014 and 2016 figures and will resubmit these  when complete. This will improve comparability between the household data within WstatR and that submitted under the Waste Framework Directive.

UK: Household figures synchronised with published values

Figures reported in EP_HH column of generation template represent published WFD Waste from Households generation.

The comparability between WStatR 2016 and WStatR 2018 remains good.  Tonnages reported in the EP_HH column in WStatR 2018 match published values.

England: Minor changes to CD&E methodology

The CD&E methodology relies heavily on estimates of aggregate and soil provided to us by the Mineral Products Association. For their 2016 data, they revised their methodology slightly, as well as back-revising some figures in line with revisions to the index for construction output that were published by the Office for National Statistics.

Revisions were made on a consistent basis and submitted for WStatR 2010, 2012 and 2014.

England: significant changes to Commercial & Industrial methodology 

Following consultation with industry, significant changes were made to the C&I methodology for England in 2018, and included in WStatR for 2016 onwards. These essentially removed the tonnages of waste received by “intermediate” treatment stages from the permitted site data, and replaced them with alternative estimates for dry recyclates from reprocessors and trade associations.  Additional improvements have been made to account for RDF and sorting residues from residual waste, which were not captured by the original Reconcile methodology. 

Revisions  have been made on a consistent basis for the 2010 and 2012 WStatR returns

England: Changes to Co-mingled waste

In England, prior to 2018, it was not possible to separate co-mingled waste collected exclusively from households (as opposed to commercial) into individual waste types (e.g. glass, plastic, metal).  Therefore the total tonnage, prior to 2018, for co-mingled waste collected has been recorded on the generation template as 'Mixed and undifferentiated materials'. For 2018 the co-mingled recylates tonnages collected exclusively from households have now been separated into the individual materials (glass, plastic, metal, textiles and paper) using proportions derived from composition waste studies carried out by WRAP (Waste and Resources Action Programme).  The total tonnages recorded on the generation template as ‘Mixed and undifferentiated materials’ will now be lower.

We are currently awaiting similar composition estimates for earlier years – we intend to make revisions to the 2010, 2012, 2014 and 2016 figures and will resubmit these when complete. This will improve comparability between the household data within WstatR and that submitted under the Waste Framework Directive.

UK: updated slate waste factor for Mining waste

Revisions were made on a consistent basis and submitted for WStatR 2010, 2012 and 2014. Limited data was available for 2018so some proportions from 2014 were used to estimate production. This should not impact comparability.

UK: changes to methodology and reporting for ELVs

Prior to WStatR 2016, ELV figures were based on the ELV Directive data, plus additional estimates for non-directive vehicles and assigned to NACE EP_HH (Household). Additional relatively small tonnages were captured as part of the C&I and Agriculture methodologies.

The revisions to the C&I methodology introduced for WStatR 2016 have resulted in essentially all tonnages of ELVs being captured by the C&I methodology. There is no accurate way to apportion these between household and non-household sources and so they will now all be reported as NACE G-U_X_G4677 (Services), in line with Eurostat guidance. This has also improved the comparability between the Household column and the Waste Framework Directive data. The ELV tonnages were sense-checked against the ELV Directive data.

Additionally, following Eurostat Guidance issued at the 2018 Waste Statistics Working Group meeting, tonnages of “Discarded vehicles” have been removed from the Treatment template, on the assumption that these are double-counting later treatment of the constituent parts.

Revisions were made on a consistent basis and submitted for WStatR 2010, 2012 and 2014.

UK: freshwater dredging exercise not included

Previous to WStatR 2014. an exercise was carried out to estimate freshwater dredging across the UK.  A review determined that the tonnage is near negigible and may already be captured via CD&E or C&I processes.  This has no material result on comparability as the tonnages involved are so small (~100Kt), and the methodology has been consistent for WStatR 2014, 2016 and 2018.

UK: minor changes to Fishing waste methodology

Northern Ireland:revisions to CD&E methodology

 Northern Ireland collected administrative data from more sources where aggregates reprocessing was undertaken to increase accuracy re this waste stream for 2016 onwards.

Scotland: significant changes to Commercial & Industrial methodology

C&I estimates for 2010 were largely survey based. Estimates for 2012 onwards have been based on site returns data. Operators were sent a summary of the annual returns and asked to allocate a SIC code to the waste generated. 

Scotland: inclusion of aggregate dataset

An aggregate directory for waste converted to aggregate meeting a quality protocol was used to estimate waste input to aggregate producers and aggregate produced.  2012 was the first year that this was used.  The aggregate directory is managed by Zero Waste Scotland (previously part of WRAP).  From 2016 this aggregate dataset was used to obtain waste data for sites that operated under a simple exemption only.  For sites that operate under a waste management licence, waste used to produce aggregate was calculated from the inputs and outputs to/from the sites of chapter 17 and chapter 19 coded waste.

Wales: regross of  Construction & Demolition 2012 survey estimates

Estimates for C&D 2012 were survey based. In the absence of a similar survey for 2018, the estimates were re-grossed. This approach is consistent with previous submissions for Wales in 2016 & 201 (re-grossed I&C and C&D 2012 survey estimates), 2010 (re-grossed I&C 2007 survey estimates) and in 2008 (re-grossed C&D 2005-06 survey estimates).

Using business population data from the Inter-Departmental Business Register (IDBR) extracts, a ‘growth factor’ was determined separately for each of the construction & demolition sectors. The growth factor looked at the net change in the number of employees in every active business in Wales between March 2012 and March 2018.

Net changes in employment were assumed to represent changes in activity levels in a given sector, which themselves were assumed to be proportional to the change in the amount of waste generated. There is likely to be a slight lag in the currency of IDBR extracts as a result of the detailed maintenance process that has to be applied to the IDBR, involving analysis of Her Majesty’s Revenue and Customs (HMRC) data and business profiling etc.

The growth factors are a ratio of the recent /historic population (Factor = 2018 population/2012 population) for each of the industry sectors. These were applied to the relevant 2012 waste estimates uniformly across waste types to generate 2018 estimates; i.e. the estimates assume that there have been no changes in the distribution of waste by waste type. This means that if the waste estimates for a particular sector and/or waste type was zero in 2012 then this will also be true in 2018, as any multiplication of zero and a growth factor will always result in a zero.

The estimation approach also assumes no changes in waste management practice (for example, due to any changes in legislation or new Regulations) between the time when the surveys were conducted (in 2012) and 2016.

Wales: CD&E survey replaced by modelling

 For 2016, Wales estimated CD&E by modelling past survey results rather than running the survey.

Wales: I&C survey 2018 completed

The survey methodology was consistent with 2012 and adopted a stratified sampling scheme based on Standard Industrial Classification sectors and size bands. For a given total sample size, the number of business units to be surveyed in each brick sample frames were optimised to provide the best possible precision for the total national waste generated for both surveys. This was done by taking into account (i) the total number of businesses in each the expected variation in waste generation among businesses in each brick. Businesses were recruited by telephone and selection was dictated by business size and sector in the sample matrix. Surveys were via a structured face-to-face interview at business sites, using a laptop and database questionnaire, with a subsequent site walk around to identify any waste streams that may have been overlooked during. Full details of the method of waste collection are available on the Natural Resources Wales website.

Coherence in terms of waste types is good with all returns from permitted sites using LoW codes. 

The data on household waste uses a non-standard set of waste codes defined within the WasteDataFlow system, which applies in all four UK countries.  These have to be mapped to EWC-STAT.  For 2014 onwards Defra and the Devolved Administrations agreed on a synchronised set of mappings to ensure consistency across countries.

For other wastes, assumptions have to be made as to which EWC-STAT to use.  In most cases (e.g. dredging spoils and mining waste) these are obvious.  They are less obvious for waste processed under exemption.  Exemption holders are restricted to a list of specific EWC codes, but determining the split between these requires assumptions.

Coherence with other published statistics is good.  WStatR has now been established as part of an Official Statistics release first published in September 2014.  Care has been taken to ensure coherence with other statistics.  The EP_HH column of the generation template is synchronised with published WFD figures.  CD&E figures are synchronised with those reported under the WFD.  Differences will still exist, but will be easier to explain.  The Common Sludges field for industry E36_E37_E39 has been set to match the UWWT for each of the four countries of the UK. 

There are no obvious socio-economic datasets to compare WStatR to.

2. Keep confidential information secure. Only permit its use by trained staff who have signed a declaration covering their obligations under this Code.

3. Inform respondents to statistical surveys and censuses how confidentiality will be protected.

4. Ensure that arrangements for confidentiality protection are sufficient to protect the privacy of individual information, but not so restrictive as to limit unduly the practical utility of official statistics. Publish details of such arrangements.

5. Seek prior authorisation from the National Statistician or Chief Statistician in a Devolved Administration for any exceptions, required by law or thought to be in the public interest, to the principle of confidentiality protection. Publish details of such authorisations.

6. In every case where confidential statistical records are exchanged for statistical purposes with a third party, prepare written confidentiality protection agreements covering the requirements under this Code. Keep an operational record to detail the manner and purpose of the processing.
