Wales Construction and Demolition waste arisings survey
Arolwg o Sgil-gynhyrchion Gwastraff Adeiladu a Dymchwel yng Nghymru

The purpose of the study was to provide information on the types, quantities, origins (by Construction and Demolition sector and geographic region), and fate (management method) of Construction and Demolition (C&D) wastes generated by businesses and the public sector in Wales in 2019. This is a stand-alone survey and supersedes the data from the last survey for the 2012 calendar year. This information is required for a variety of reasons including:


• statutory reporting on waste generation in compliance with Part 2 of Schedule 1 of the Waste (England and Wales) Regulations 2011 and, up until 2020, the EU Waste Statistics Regulations 2002;

• informing the development of national waste policy;

• monitoring progress against national waste prevention and recycling targets;

• informing waste planners and the regulator;

• supporting investment decisions such as the selection of the type and scale of new waste management facilities required by local authorities and the waste industry;

• updating the evidence base for the State of Natural Resources Report Wales assessment (Natural Resources Wales 2021), and;

• providing businesses with a better understanding of their current waste practices and for developing sustainable waste management support strategies by Welsh Government for improving environmental performance of businesses.


The precision for the total waste generated in Wales was +/- 16.7% at 90% confidence. Results from all surveys are subject to limitations with respect to the quality of estimates produced. Whilst these limitations do not alter the results or the statistical data, they should be borne in mind by users of the data. Information on waste management in the report is generally reliable but the accuracy of the results is limited to information available to surveyed producers on the final destinations of their waste. The accuracy is limited owing to the complexities of waste management routes and difficulties linking final fate back to source.


Further information, including on the survey confidence, is contained in the published survey report. The detailed survey technical appendices are also available on request.

Diben yr astudiaeth oedd darparu gwybodaeth am fathau, symiau, tarddiadau (yn ôl y sector Adeiladu a Dymchwel a'r rhanbarth daearyddol), a thynged (dull rheoli) gwastraff Adeiladu a Dymchwel a gynhyrchwyd gan fusnesau a'r sector cyhoeddus yng Nghymru yn 2019. Mae hwn yn arolwg annibynnol ac mae'n disodli'r data o'r arolwg diwethaf ar gyfer blwyddyn galendr 2012. Mae angen y wybodaeth hon am amryw o resymau.


Lefel y manylder ar gyfer cyfanswm y gwastraff a gynhyrchwyd yng Nghymru oedd +/- 16.7% ar hyder o 90%.


Mae cyfyngiadau’n bodoli o ran ansawdd yr amcangyfrifon a gynhyrchir ar gyfer canlyniadau pob arolwg. Er nad yw'r cyfyngiadau hyn yn newid y canlyniadau na'r data ystadegol, dylai defnyddwyr y data eu cadw mewn cof.


Casglwyd data o sampl gynrychioliadol o 508 o safleoedd busnes o wahanol sectorau a meintiau ledled Cymru rhwng mis Ebrill 2021 a mis Medi 2021. Cafodd y data ei grosio gan ddefnyddio data poblogaeth safleoedd busnes y Swyddfa Ystadegau Gwladol (SYG) i lefel ranbarthol a chenedlaethol yng Nghymru.


Roedd y fethodoleg a ddefnyddiwyd i ddatblygu'r matrics samplu a'r gwaith dilynol o grosio canlyniadau'r arolwg yn seiliedig ar arolygon Adeiladu a Dymchwel blaenorol yng Nghymru i sicrhau y gellid cymharu’r canlyniadau. Cafodd dyluniad y matrics samplu ei hun ei newid ychydig o'r hyn a ddefnyddiwyd yn 2012, drwy gyfuno is-sectorau Adeiladu Cyffredinol yn un sector.


Roedd y matrics samplu’n diffinio faint o safleoedd busnes yr oedd angen eu cyrraedd ar gyfer pob bricsen. Fe'i hadolygwyd ran o'r ffordd drwy'r arolwg i ymgorffori anghysondebau o ran sector neu faint cwmnïau a nodwyd yn set ddata wreiddiol y Swyddfa Ystadegau Gwladol (SYG) yn ystod y broses recriwtio, er mwyn adlewyrchu cyfraddau recriwtio gwirioneddol o fewn briciau.


Mae gwybodaeth am reoli gwastraff yn yr adroddiad yn ddibynadwy ar y cyfan ond mae cywirdeb y canlyniadau wedi'i gyfyngu i'r wybodaeth oedd ar gael i gynhyrchwyr a arolygwyd ar gyrchfannau terfynol eu gwastraff. Mae'r cywirdeb yn gyfyngedig oherwydd cymhlethdodau o ran llwybrau rheoli gwastraff ac anawsterau wrth gysylltu tynged derfynol yn ôl i'r ffynhonnell.


Ceir rhagor o wybodaeth, gan gynnwys gwybodaeth o ran hyder yr arolwg, yn adroddiad cyhoeddedig yr arolwg. Mae atodiadau technegol manwl yr arolwg hefyd ar gael ar gais.

Lineage

Data was collected from a representative sample of 508 business sites of differing sectors and sizes throughout Wales between April 2021 and September 2021. The data was grossed up using Office for National Statistics (ONS) business site population data to regional and national level in Wales.


The methodology used for development of the sample matrix and subsequent grossing of the survey results was based on previous Wales C&D surveys to ensure comparability of results. The design of the sample matrix itself was changed slightly from that applied in 2012, with the consolidation of General Building subsectors into a single sector.


The sample matrix defined how many business sites needed to be reached for each brick. It was reviewed part way through the survey to incorporate inconsistencies in company size or sector that were identified in the original Office of National Statistics (ONS) dataset during recruitment, in order to reflect actual business recruitment rates within bricks.


Further information on the survey data collection and quality assurance methods is available in the published survey report and the detailed technical appendices are also available on request.
