Clinical waste for veterinary practices: a UK guide for 2026
The main waste streams in a vet practice
| Waste type | Typical container | Notes |
|---|---|---|
| Sharps contaminated with medicines | Yellow-lidded sharps bin | Most needles and syringes from injections |
| Sharps with cytotoxic or cytostatic drugs | Purple-lidded sharps bin | Chemotherapy and some hormone drugs |
| Infectious animal waste | Yellow or orange bag or bin | Swabs, dressings, contaminated items |
| Medicines and part-used vials | Blue-lidded container | Non-cytotoxic medicines |
| Offensive waste | Yellow and black striped bag | Non-infectious bedding, gloves, aprons |
| Carcasses and body parts | Freezer, then licensed collection | Animal By-Products Regulations apply |
| X-ray and lab chemicals | Separate hazardous containers | Less common with digital imaging |
Your contractor will confirm the exact container colours and waste codes they use, as practice can vary slightly between suppliers.
Animal healthcare waste codes
Waste from diagnosis, treatment or prevention of disease in animals falls under the 18 02 section of the European Waste Catalogue list used in the UK, rather than 18 01 for human healthcare. For example, infectious animal healthcare waste is usually coded 18 02 02, cytotoxic medicines 18 02 07 and other medicines 18 02 08. These codes go on your waste transfer notes and hazardous waste consignment notes.
Getting the codes right matters because the treatment route depends on them. Infectious and cytotoxic animal waste is hazardous and needs a consignment note, while some non-hazardous streams can travel on a waste transfer note. If your paperwork uses human healthcare codes for animal waste, ask your contractor to correct it.
Carcasses and animal by-products
Dead pets and animal body parts are animal by-products, not standard clinical waste. They are normally stored frozen at the practice and collected by a licensed pet crematorium or animal by-products contractor for individual or communal cremation, depending on what the owner chooses.
- Keep carcasses in a dedicated freezer, not one used for food or samples
- Label each animal clearly with owner details and cremation type
- Keep records of what is collected and by whom
- Check your crematorium holds the right approval for animal by-products
Controlled drugs
Vets regularly hold controlled drugs such as ketamine and some opioids. Out-of-date or unused stock must be denatured, using a denaturing kit, before it leaves the practice. In England this is usually done under a T28 waste exemption, which is free to register, lasts three years and limits storage to one cubic metre for up to six months.
Destruction of certain controlled drugs must be witnessed by an authorised person and recorded in the controlled drugs register. The Royal College of Veterinary Surgeons and the Veterinary Medicines Directorate publish guidance, and your practice standards scheme may set extra requirements.
Storage and segregation tips
- Place sharps bins at the point of use in consult rooms and theatre
- Use purple-lidded bins wherever cytotoxic drugs are given, including in-patient wards
- Keep full bags and bins in a locked, labelled store until collection
- Do not mix carcasses with general clinical waste
- Train all staff, including receptionists and nurses, on what goes where
- Review segregation regularly, as offensive waste is often wrongly sent as infectious
Pre-acceptance audits for vets
Clinical waste contractors need a pre-acceptance audit describing the waste you produce. Vet practices are often treated as a higher-risk healthcare producer because of the mix of cytotoxic drugs, infectious waste and animal tissue, so audits may be needed more often than for low-risk producers. Ask your contractor what frequency they require.
Equine, farm and mobile vets
Ambulatory vets who visit farms, stables and homes produce waste on the road as well as at the practice. Waste produced during a visit is generally treated as the practice's waste, so it should come back to the practice for disposal rather than being left with the client.
- Carry a sharps bin and clinical waste bag secured in every vehicle
- Use rigid, lidded containers that cannot spill during driving
- Bring full containers back to the practice store at the end of the day
- Do not leave sharps or medicines on the farm, even if the client offers to dispose of them
- Keep a simple log of waste carried, so it matches your collections
- Check vehicle insurance and practice policy for carrying hazardous waste
Large animal carcasses on farms are handled separately through fallen stock services rather than the practice's clinical waste. The farmer is usually responsible for arranging collection, though the vet may advise on the right route.
Frequently asked questions
Can a vet practice put animal carcasses in clinical waste bins?
Generally no. Whole animals and large body parts are animal by-products and should be collected by a licensed pet crematorium or animal by-products contractor. Small amounts of tissue from procedures may be handled as anatomical or infectious waste depending on your contractor's arrangements. Check with both your waste contractor and crematorium.
Do vets need a T28 exemption?
If the practice denatures waste controlled drugs before disposal, it will usually need a T28 waste exemption in England, which is free to register with the Environment Agency and lasts three years. Wales, Scotland and Northern Ireland have their own regulators and arrangements. Exemption rules are expected to change from January 2027, so check current guidance.
How often should a vet practice have clinical waste collected?
It depends on size and volume. Small single-vet practices may manage with fortnightly or monthly collections of sharps and clinical waste, while busy hospitals with theatres and in-patients often need weekly collections or more. Carcass collections are usually arranged separately with the crematorium, often weekly. Review the schedule if you add services such as chemotherapy or out-of-hours cover, as volumes and waste types can change quickly.
