2-Dimensional (2D) Waste View
Flat or compressible waste materials, such as paper, card, textiles, or films.
The glossary and acronyms used across the UK waste management sector are listed here for reference.
Entries are grouped alphabetically. Each entry opens the full wording of the acronym and provides a link to a more detailed page on the subject, whether that relates to a waste type, facility type, or organisation.
Definitions are reviewed and expanded as datasets and guidance are updated. For formal interpretation, users should always refer to official regulatory documents or statutory guidance.
