R and D codes describe waste operations: what happens to the material. Separate waste classification codes identify the waste itself. An R13 entry therefore answers a different question from a six-digit List of Waste code, and neither should be treated as a complete description of a waste service.
The codes become especially useful when you read a permit, investigate a transfer facility or try to understand a recovery claim. They can also be misleading when a preliminary stage is presented as though it proves the final outcome.
This guide explains the common codes and how to read them alongside the rest of the evidence. Official sources were reviewed on 12 October 2026. For the broader authorisation framework, start with our registrations and permits guide.
What do R and D waste codes mean?
R codes identify recovery operations and D codes identify disposal operations. The official lists appear in the Waste Framework Directive annexes and are reproduced in the Environment Agency’s reporting codes guidance. Use the complete descriptions when making a technical decision.
For everyday interpretation, ask which operation the code describes and at which stage in the journey it occurs. A transfer site’s storage operation may be followed by treatment and a separate final destination. The first site’s code does not necessarily describe everything that follows.
Imagine a fictional producer sends material to a depot for consolidation before specialist processing elsewhere. The depot’s operation and the processing facility’s operation are separate evidence questions, even if one contractor organises both.
Keep that distinction in your records. Write the facility, stage and code together, rather than putting one unexplained code against the supplier’s entire service. A colleague can then follow which part of the recovery or disposal route the record describes.
How are R and D codes different from six-digit waste codes?
A List of Waste or European Waste Catalogue code identifies a waste category. An R or D code identifies an operation. The Environment Agency’s official reporting guidance distinguishes both systems.
For a practical example, a description of the material can stay recognisably similar while different facilities perform different operations on it. Knowing what it is does not establish whether a particular site stores, treats, recovers or disposes of it.
Conversely, an operation code can apply to several eligible waste types, subject to the site’s actual permission. It is not a shortcut around reading the waste list and relevant restrictions.
When reviewing a document, label the two fields clearly. Avoid a spreadsheet heading simply called “waste code” where colleagues might enter either system. Our guide to reading a waste permit explains how activity schedules, waste tables and conditions fit together.
Which recovery and disposal codes commonly appear?
The following are short descriptions to help you recognise common entries. They are not a replacement for the full legal descriptions or the relevant permit conditions.
| Code | Short description |
|---|---|
| R1 | Waste used mainly as fuel or to generate energy |
| R2 | Recovery or regeneration of solvents |
| R3 | Recovery of organic materials, including composting |
| R4 | Recovery of metals and metal compounds |
| R5 | Recovery of other inorganic materials |
| R10 | Land treatment benefiting agriculture or ecology |
| R12 | Exchange ahead of specified recovery operations |
| R13 | Storage ahead of recovery |
| D1 | Deposit onto or into land |
| D9 | Specified physical or chemical treatment before disposal |
| D10 | Incineration on land |
| D15 | Storage ahead of disposal |
These summaries draw on the Environment Agency’s complete code list. There are other codes, and the detail matters. If your operation is unfamiliar, use the complete list rather than forcing it into the nearest familiar row.
What does R13 mean for a transfer station?
R13 describes storage before the listed recovery operations. Its definition excludes temporary storage awaiting collection at the site of production. See the official R13 description.
The practical implication is that a site can be part of a recovery route without carrying out the final recovery itself. A genuine R13 activity should not be described as proof that material has already been recycled at that location.
Ask where the material goes next and what operation happens there. If you are preparing a customer report, distinguish collection, intermediate storage and the reported final outcome. A storage stage is meaningful information, but its meaning is narrower than a completed recovery claim.
For waste still held by its original producer, use storing your own business waste. The applicable temporary storage route should be assessed on its own terms, rather than assuming any business bin area needs a commercial R13 site permission.
What does D15 mean and how is it different from R13?
D15 concerns storage before the listed disposal operations, again excluding temporary storage awaiting collection at the production site. Its full wording is in the official disposal code list.
The distinction concerns the route the storage supports, not simply the appearance of the storage area. Two similar containers could hold material going to different subsequent operations. A photograph cannot resolve the code without the underlying activity information.
A practical review should ask which streams follow which route. A facility might handle several streams and activities. Do not turn one D15 entry into an assumption that all material received there is ultimately disposed of, or one R13 entry into an assumption that everything is recovered.
Our guide to checking the waste destination helps apply that distinction to a real service. Keep each code connected to the operation and material described in the evidence.
Does R12 prove that recycling has been completed?
No. Read it as an operation within the described recovery chain, rather than a certificate of final recycling. The operator should explain the actual process and onward route supported by its permission.
For a real English example, SR2022 No 2 for mobile waste treatment sets out permitted recovery activities and the particular treatment limits within that rules set. The activity description and restrictions matter alongside any operation code.
Ask the operator to describe what enters the process and what happens during treatment. Then trace the outputs and where each one goes. This can reveal whether the evidence describes preparation, separation, recovery or another stage.
If you are reporting recycling performance, ask what evidence supports the actual claimed outcome. Do not promote a preliminary operation into completed recycling merely because its code begins with R. Explain which stage remains before the claimed outcome can be established, and give the basis for any percentage you report.
Is energy recovery the same as recycling?
Keep the terms separate. They describe different outcomes. A recovery claim should identify the actual operation instead of using recycling as a general synonym for every route that avoids landfill.
Municipal waste incineration provides an important example. The Environment Agency’s R1 status guidance for England explains the eligibility, energy-efficiency assessment and confirmation involved in classifying relevant incineration as recovery. Producing energy does not by itself settle that classification.
For a practical customer enquiry, ask for the named receiving facility and evidence supporting the stated status where it matters to your decision. Do not infer R1 from a supplier’s phrase “energy from waste”. Also keep the facility’s status separate from the question of whether your particular load actually went there.
If a contractor offers several routes, record them separately. A mixed service can involve recycling of some material and another recovery route for the remainder. Combining those outcomes into one unqualified recycling statement makes the service harder to understand.
Does an R code show that material has stopped being waste?
No. An operation code does not alone establish end-of-waste status. In England, the Environment Agency explains that material must undergo recycling or another recovery operation and meet the applicable end-of-waste conditions before it is treated as non-waste. See check if your material is waste.
When someone describes an output as a product, aggregate or fuel, ask for the evidence establishing its end-of-waste status and intended use. The commercial description alone cannot provide the legal answer.
For a practical example, a recovered-looking material in a stockpile might still require waste controls if the relevant end-of-waste position has not been established. Its clean appearance or sale value cannot explain the full assessment.
Use the applicable national regulator’s guidance for the actual material and route. Keep a separate field for material status in your review, so “R operation identified” does not automatically become “non-waste product confirmed”.
Is depositing waste for a useful project always recovery?
The project needs a proper assessment. In England, the Environment Agency’s deposit for recovery guidance requires evidence that the works could and would be carried out using non-waste material. Its approved waste recovery plan forms part of the permission.
For example, calling a large deposit landscaping does not explain whether the amount and material serve the stated purpose. Ask how the design supports the need, which material is suitable and what the approved recovery plan allows.
The practical reading method is to compare the scheme’s purpose, design, waste description and permission. A code in a table should not replace those documents. Where the proposed quantity or design changes, revisit the basis rather than assuming the original label continues to fit.
In Wales, NRW provides its own permission guidance for deposit for recovery, including separate questions about treatment and planning. Use the appropriate national route.
Are the codes the same as permit authorisation?
A code describes an operation; it does not grant permission by itself. Read it within the actual permit or other applicable authorisation, alongside the holder, place, waste scope and limits.
For a practical example, a site may have an R4 activity relevant to specified metals. That does not establish permission for every treatment process involving every metal-containing waste. The details in its granted documents determine the operating envelope.
Likewise, a carrier registration is not an authorisation to undertake all the recovery activities that appear in the supplier’s marketing. Use what carrier registration covers to keep transport and site permissions separate.
If the current permission does not cover a proposed operation, identify the proper change process. Our permit variation guide explains how to distinguish the current authorised activity from a requested future change.
How should Scottish waste operation evidence be read?
Scotland’s authorisation framework is EASR. Read the operation code within the actual Scottish permission and applicable conditions, rather than using an England and Wales rules set as a substitute. Our Scottish EASR guide explains the framework.
SEPA’s public register information explains how current authorisations and older WML or PPC references are searchable. Obtain the documents relevant to the activity before deciding what an isolated code means.
A useful cross-country comparison can retain the original operation description and code while keeping the authorisation route distinct. The fact that similar shorthand appears in two documents does not prove that their conditions, locations or permitted materials are identical.
If the source uses older terminology, ask how it relates to the current permission. Preserve the actual wording in your evidence record rather than replacing it with a simplified label that loses the operating restrictions.
How should you use R and D codes in waste reporting?
Explain what the figures cover. Identify the material, period, facility and stage, and distinguish a planned route from evidence of the route actually used. These are recommended reporting practices, not a substitute for any formal return’s specific instructions.
An operator’s permit shows an authorised scope. It does not alone establish the fate of every load accepted during a reporting period. A supplier’s estimate or standard service description may require further evidence before it supports a claim about your own waste.
The England and Wales duty of care code addresses waste management throughout the journey, including preliminary treatment and cooperation between holders. That is one reason to keep the onward route visible rather than stopping at the first R code.
For a practical report, write “received for storage before onward recovery” where that is what the evidence establishes. Reserve stronger outcome claims for evidence that actually supports them. Clear language makes the data more useful to customers and colleagues.
How can you explain a mixed waste route clearly?
Consider a fictional load that is separated into several outputs after arriving at an intermediate facility. One output moves to a recycler, another follows an energy route and a residue goes for disposal. A single code against the original collection cannot explain that whole chain without further context.
For practical reporting, keep the material quantities and stages connected. Explain whether the evidence concerns the original load, a separated output or an estimated share of a wider reporting period. Ask how the figures were obtained and avoid presenting a site-wide average as a measured outcome for one customer unless that is an appropriate and clearly disclosed basis.
Where the data does not distinguish the outputs, say what is known and which part remains unresolved. That produces a useful account without guessing a final destination. Keep the unresolved point specific, so later evidence can be checked against that gap and the report updated without having to correct an unsupported headline.
What questions help resolve an unfamiliar operation code?
Ask which activity the code describes, where it happens and which waste streams it covers. Then ask what happens before and after that stage. Request the relevant permit condition or approved document, rather than an unsupported explanation of the code in isolation.
For example: “The record lists storage before recovery. Which facility undertakes the next stage for this material, and what evidence supports that route?” This question is specific enough to produce information you can assess.
Keep the answer with the document reference and check date. If several routes are available, record the alternatives and what determines the route actually selected. Revisit the explanation when the process or destination changes.
Once you understand the operation, use the code as shorthand in your evidence record. Keep the process description and current permission alongside it, and state which outcome the evidence supports. That lets another reader follow the route without having to infer the whole arrangement from the letters and numbers.
