Waste Transfer Notes for Farms and AD Plants: A Complete Guide
Farms, agri-businesses and anaerobic digestion operators generate controlled waste regularly. Every time that waste leaves your site, a Waste Transfer Note is legally required. Getting it wrong can mean fines of up to £5,000 — or unlimited fines for serious breaches.
The Basics
What Is a Waste Transfer Note?
A Waste Transfer Note (WTN) is a legal document required under the Environmental Protection Act 1990 Duty of Care provisions. It must be completed every time controlled waste is transferred from one party to another — whether that's a farm handing waste to a contractor, an AD plant dispatching rejected digestate, or a food processor removing packaging waste.
Both the waste holder (the person handing over the waste) and the waste carrier (the registered business collecting it) must sign the WTN and retain a copy. The document creates a paper trail that demonstrates the waste has been handled legally and passed to an authorised party. Relevant regulators are NIEA in Northern Ireland, the Environment Agency in England, SEPA in Scotland, and Natural Resources Wales.
The duty of care applies to all businesses — not just waste companies. If your farm or AD plant generates controlled waste, you have legal obligations as the waste holder regardless of whether waste management is your primary business.
Practical Guidance
When Do Farms & AD Plants Need a WTN?
The trigger is simple: controlled waste leaving your site in the hands of a third party. Below are the most common situations agricultural businesses and AD operators encounter in practice.
| Waste Type / Situation | WTN Required? |
|---|---|
| Slurry spread to own land under an NMP | No — not controlled waste |
| Slurry tankered off-farm for disposal by a contractor | Yes |
| Rejected or surplus digestate disposed of off-site | Yes |
| PAS110-certified digestate applied to land under NMP | No — end-of-waste |
| Food waste delivered to AD plant by a carrier | Yes — carrier must provide WTN |
| Farm plastics, silage wrap collected by contractor | Yes |
| Asbestos or demolition waste from farm buildings | Yes |
| Green waste / compost moved off-site for sale or disposal | Yes |
Animal By-Products (ABPs) such as fallen stock or category 3 materials may require both an ABP movement document and a WTN, depending on how they are classified and moved. If your operation handles ABPs regularly, seek specific advice on the interaction between ABP and waste regulations.
Completing the Document
The Five Sections of a WTN (Parts A–E)
A standard WTN has five sections. Each must be completed accurately — regulators routinely identify non-compliant WTNs during inspections through vague descriptions or missing registration numbers.
Part A — Waste Holder Details
This section identifies who is handing over the waste — the farm, AD plant, or food processor. You will need your business name, address, SIC code, and the number of any relevant waste exemption or Environmental Permit. If you hold a T registration for an exempt activity, that goes here.
Part B — Waste Carrier Details
The registered carrier collecting the waste. Record their company name, address, carrier registration number, vehicle registration, and driver name. Always verify the carrier's registration on the EA or NIEA public register before handing over waste — using an unregistered carrier makes you liable even if you acted in good faith.
Part C — Place of Transfer
Where the waste is going — the receiving site name, address, environmental permit or exemption number, and operator name. For AD operators receiving food waste, this section on the incoming WTN should reflect your site details and permit number accurately.
Part D — Waste Details
The most scrutinised section. You must provide a clear written description of the waste, the correct European Waste Catalogue (EWC) code, physical form, quantity, and containment method. Vague descriptions like 'farm waste' are a common compliance failure and can invalidate the WTN.
Part E — Transfer Details
The date, location, and reason for the transfer. This section also requires confirmation that the waste hierarchy has been considered — reduction, reuse, recycling, and recovery before disposal.

Repeat Collections
Season Tickets — When to Use One
A Season Ticket covers repeat transfers of the same waste type between the same parties over a period of up to 12 months. One document replaces individual WTNs for each collection, making it significantly more practical for operations with regular waste movements.
For farms and AD plants, common Season Ticket use cases include weekly food waste deliveries from the same supplier, monthly farm plastics collections, or regular packaging waste uplifts. All the same information must be recorded as on a standard WTN — the difference is that it covers multiple future collections in a single document rather than requiring a new WTN each time.
Both parties must still sign the Season Ticket and retain a copy. Any material change to the waste type, quantity, carrier, or receiving site requires a new document.
Record Keeping
How Long Must You Keep WTNs?
Retention requirements vary by jurisdiction. Both the waste producer and the receiving site must keep their copies:
| Jurisdiction | Minimum Retention | Who Must Keep It |
|---|---|---|
| England & Wales | 2 years | Both producer and receiver |
| Scotland | 3 years | Both producer and receiver |
| Northern Ireland | 2 years | Both producer and receiver |
Modern Practice
Paper vs Digital WTNs
Digital WTNs are fully legal under UK law and e-signatures are accepted by all four UK regulators. From October 2026, the mandatory Digital Waste Tracking (DWT) system will require waste movements to be recorded digitally — particularly relevant for AD operators receiving food waste or other regulated inputs, who will need to demonstrate a full digital audit trail.
Paper WTNs create practical and audit risk that digital records eliminate entirely. A misfiled or lost WTN discovered during a NIEA inspection can result in a formal caution even where the transfer itself was compliant. For operations handling multiple waste streams or frequent collections, the filing burden of paper WTNs can also become substantial.
| Paper WTN | Digital WTN | |
|---|---|---|
| Legally valid | ✓ | ✓ |
| E-signatures accepted | ✗ | ✓ |
| Accessible during inspection | Filing cabinet required | Any device, instantly |
| DWT 2026 ready | ✗ | ✓ |
| Risk of loss or damage | High | None |

Enforcement
Penalties for Non-Compliance
Failure to produce a WTN, handing waste to an unregistered carrier, or keeping inadequate records are all breaches of the Duty of Care under the Environmental Protection Act 1990. A fixed penalty notice of up to £300 can be issued in England; prosecution in a magistrates' court can result in fines up to £5,000. Serious or repeat offences tried in the Crown Court carry unlimited fines.
NIEA in Northern Ireland has equivalent enforcement powers under the Controlled Waste (Registration of Carriers and Seizure of Vehicles) Regulations (NI) 1999. AD operators should note that Duty of Care breaches can also trigger a review of their Environmental Permit — a significant risk where permit conditions govern feedstock acceptance and waste outputs.

Common Questions
Frequently Asked Questions
Do farms need waste transfer notes?
Yes. Any farm business that transfers controlled waste off-site — whether that's farm plastics, obsolete machinery, rejected digestate, or waste from a farm shop — must issue or receive a valid WTN. Slurry spread to your own land under an NMP is not controlled waste, but anything removed by a third party almost certainly is.
Do AD plants need waste transfer notes for digestate?
Digestate applied to land under a compliant Nutrient Management Plan is generally classified as a by-product or end-of-waste material (where PAS110 certified), not controlled waste, and does not require a WTN. However, if digestate is rejected, disposed of, or moved off-site in a way that does not meet end-of-waste criteria, a WTN is required.
What is the EWC code for farm waste?
It depends on the waste type. Common codes for agricultural operations include 02 01 03 (plant-tissue waste), 02 01 06 (animal faeces and manure in certain disposal contexts), 15 01 01 (paper and cardboard packaging), and 17 09 04 (mixed construction and demolition waste from farm buildings). Always confirm the appropriate code with a qualified consultant.
Is a WTN required for food waste deliveries to an AD plant?
Yes. The carrier bringing food waste feedstocks to your AD plant must hold a valid waste carrier registration and must provide a WTN for each delivery (or a Season Ticket for repeat collections). As the receiver, you should check carrier registration and retain your copy of the WTN for at least 2 years.
How do I check if a waste carrier is registered?
In England, use the Environment Agency public register. In Northern Ireland, check the NIEA carrier registration database. Always verify before accepting a waste delivery — using an unregistered carrier exposes you to liability even if you were unaware of their unregistered status.
