The waste hierarchy explained: 5 steps and the WTN declaration

Last updated 24 August 2026

In short

The waste hierarchy is a legally binding priority order for managing waste, set by Article 4 of the EU Waste Framework Directive and given effect in England and Wales by Regulation 12 of the Waste (England and Wales) Regulations 2011. The five steps, in order, are: prevention, preparing for reuse, recycling, other recovery (including energy recovery) and disposal. Anyone who imports, produces, collects, transports, recovers, disposes of, deals in or brokers waste must take reasonable measures to apply it in that order — and confirm they have done so on every waste transfer note or hazardous waste consignment note.

The waste hierarchy is not just a poster on the wall — it is a legal priority order every UK business that handles waste has to apply, and confirm on every waste transfer note. Here are the five steps in the right order, where the duty comes from, and exactly what to declare.

What is the waste hierarchy?

The waste hierarchy is a legally binding 5-step priority order for managing waste. In order, the steps are: prevention, preparing for reuse, recycling, other recovery (including energy recovery), and disposal. Prevention is the most environmentally preferable outcome; disposal to landfill is the least.

The order comes from Article 4 of the EU Waste Framework Directive (2008/98/EC). In England and Wales it is given effect by Regulation 12 of the Waste (England and Wales) Regulations 2011, and mirrored in Scotland by the Waste (Scotland) Regulations 2012 and in Northern Ireland by the Waste Regulations (Northern Ireland) 2011. Duty of care under section 34 of the Environmental Protection Act 1990 sits alongside it: the hierarchy tells you which option to choose; duty of care tells you how to transfer waste safely once you have.

What are the 5 steps of the waste hierarchy?

The five steps, top to bottom, are: 1) prevention, 2) preparing for reuse, 3) recycling, 4) other recovery (including energy recovery) and 5) disposal. You should choose the highest step that is technically feasible and economically viable for that waste stream.
The 5 steps of the UK waste hierarchy, in priority order
StepWhat it meansEveryday example
1. PreventionAvoid creating waste in the first place — through design, purchasing, process change or extending product life.Ordering in reusable crates instead of single-trip cardboard.
2. Preparing for reuseChecking, cleaning, repairing or refurbishing whole items or components so they can be used again for the same purpose.Refurbishing office furniture; repairing pallets for another cycle.
3. RecyclingReprocessing waste materials into products, materials or substances (composting biodegradable waste counts as recycling).Sending segregated cardboard, metals or food waste for reprocessing.
4. Other recoveryAny recovery operation that is not preparing for reuse or recycling — most commonly energy recovery from residual waste.Sending residual, non-recyclable waste to energy-from-waste with heat capture.
5. DisposalAny operation that is not recovery — principally landfill or incineration without energy recovery. The last resort.Landfilling residues that cannot be recovered.

The five-level hierarchy replaced an older three-level version (prevention, recovery, disposal) when the Waste Framework Directive was recast in 2008. The separation of preparing for reuse from recycling, and of other recovery from disposal, is deliberate: it pushes waste up the ladder wherever technically and economically it can go.

Who has to apply the waste hierarchy?

Under Regulation 12(1), anyone who imports, produces, collects, transports, recovers, disposes of, or who as a dealer or broker has control of waste must, on the transfer of waste, take all reasonable measures to apply the hierarchy as a priority order. It covers producers, carriers, brokers, dealers and receivers alike.

The duty attaches to businesses ("establishments and undertakings"), not householders in their own home. It applies whether you handle non-hazardous waste, hazardous waste, or both. If you are a small carrier or a large permitted site the wording is the same — take all reasonable measures to apply the hierarchy in that order.

When can you depart from the priority order?

You may choose a lower step where a life-cycle assessment shows it delivers the best overall environmental outcome for that waste stream, taking technical feasibility and economic viability into account (Regulation 12(2)). The reasoning should be documented.

Two common examples: energy recovery may sit above recycling for a waste stream so contaminated that recycling would be worse environmentally; and prevention or reuse may be technically possible but not economically viable at the scale your site operates. The legal test is not preference — it is a defensible life-cycle case.

What is the waste hierarchy declaration on a waste transfer note?

It is a written confirmation, required by Regulation 12, that the transferor has applied the waste hierarchy. The standard wording is: “I confirm that I have fulfilled my duty to apply the waste hierarchy as required by regulation 12 of the Waste (England and Wales) Regulations 2011.” It must appear on every waste transfer note and every hazardous waste consignment note.

Since 29 September 2011, this declaration has been mandatory content on WTNs and hazardous consignment notes across England and Wales. In Scotland and Northern Ireland an equivalent declaration is required by the parallel regulations. A note without the declaration is not a compliant note — the transferor is treated as not having discharged the Regulation 12 duty, and the receiver may reasonably refuse the load.

A compliant WTN must include the Regulation 12 hierarchy declaration, the description of the waste (composition, physical form and any hazard), the correct EWC code, the SIC code of the producing activity, the parties' names, addresses and (for carriers) waste carrier registration number — and be retained for at least 2 years (hazardous consignment notes for at least 3 years).

How does the waste hierarchy interact with Digital Waste Tracking?

Digital Waste Tracking records movements of waste; it does not replace the Regulation 12 duty to apply the hierarchy. Receivers come into scope from October 2026 in England, Wales and Northern Ireland and January 2027 in Scotland; carriers, brokers and dealers from October 2027. Until then, paper or digital WTNs (still carrying the declaration) satisfy duty of care.

The practical read-across is that the hierarchy governs the choice you make — recycling vs recovery vs disposal — and Digital Waste Tracking then records what actually happened, including the disposal or recovery code applied at the receiving site. Both are needed together: the hierarchy for the decision, the tracking record for the evidence.

How to apply the waste hierarchy in practice

  • Start with prevention in procurement and process design — the cheapest tonne to manage is the one you never generate.
  • Segregate at source so preparing for reuse and recycling stay technically feasible; mixed loads collapse the hierarchy to disposal.
  • Match each stream to the correct EWC code, then choose the highest hierarchy step your receiver can actually deliver — an R-code (recovery) beats a D-code (disposal).
  • Where you have to depart from the order, keep a short life-cycle justification on file so you can defend the decision to the regulator.
  • Check that every waste transfer note and consignment note carries the Regulation 12 declaration — it is the visible evidence you have done the above.

Frequently asked questions

What are the 5 steps of the waste hierarchy?
In priority order the five steps are: 1) prevention, 2) preparing for reuse, 3) recycling, 4) other recovery (including energy recovery), and 5) disposal. Prevention is the most environmentally preferable option; disposal to landfill is the least. The order is set by Article 4 of the EU Waste Framework Directive (2008/98/EC) and Regulation 12 of the Waste (England and Wales) Regulations 2011.
Is the waste hierarchy a legal requirement in the UK?
Yes. Regulation 12 of the Waste (England and Wales) Regulations 2011 places a legal duty on anyone who imports, produces, collects, transports, recovers, disposes of, or as a dealer or broker has control of waste to take all reasonable measures to apply the waste hierarchy as a priority order on transfer. Scotland and Northern Ireland have equivalent duties under their own regulations.
What is the waste hierarchy declaration on a waste transfer note?
It is a statement, required by Regulation 12 of the Waste (England and Wales) Regulations 2011, in which the transferor confirms they have applied the waste hierarchy. The standard wording is 'I confirm that I have fulfilled my duty to apply the waste hierarchy as required by regulation 12 of the Waste (England and Wales) Regulations 2011.' It must appear on every waste transfer note and on hazardous waste consignment notes.
Do I have to follow the hierarchy in strict order every time?
You must apply it as a priority order and be able to justify departing from it. Regulation 12(2) allows a lower step to be chosen where a life-cycle assessment shows it delivers the best overall environmental outcome for that waste stream, taking technical feasibility and economic viability into account. The justification should be recorded.
Does the waste hierarchy apply to Digital Waste Tracking records too?
Yes. Digital Waste Tracking records the movement of waste but does not replace the Regulation 12 duty. When Digital Waste Tracking becomes mandatory (receivers from October 2026 in England, Wales and Northern Ireland and from January 2027 in Scotland; carriers from October 2027) the underlying duty to apply the hierarchy — and to confirm it was applied — carries over into those records.
