Pharmaceutical waste collection

We work from a list by stream. The usual contents are:

• non-cytotoxic medicines past their date, withdrawn or no longer needed
• cytotoxic and cytostatic medicines, kept apart from other stock
• part-used liquids, creams, powders, inhalers and aerosols
• trial medicines at the end of a study, once the sponsor has released them
• veterinary medicines, under their own animal healthcare codes
• diagnostic test kits and reagents that count as medicinal waste

Controlled drugs are a manual enquiry. Sharps, whether medicinally contaminated or not, usually stay with your clinical waste contractor because they use different containers and a different route. Our clinical and laboratory waste page covers how these streams meet. Radiopharmaceuticals are also outside this work, and they go to a manual enquiry.

• a list by product name and strength, split into cytotoxic and other medicines
• pack sizes and numbers, or the number and size of bins already filled
• physical form: solid, liquid, aerosol or mixed
• any stock under quarantine or recall, with its release status
• anything with a destruction certificate requirement from a sponsor or manufacturer
• your organisation's site details, and who will sign the note
• any controlled drugs held for disposal, on a separate note, without patient details

Waste from different sites should be listed by site. Each set of premises has its own note, and carrying medicines between buildings for convenience brings its own waste and security questions.

The GOV.UK classification guide gives a clear table. In human healthcare, cytotoxic and cytostatic medicines are 18 01 08*, and others are 18 01 09. In animal healthcare, the same two groups are 18 02 07* and 18 02 08. Household medicines returned to a community pharmacy are 20 01 31* and 20 01 32. Chemicals that are not medicines, such as a reagent or a disinfectant, are a separate question and sit under their own entries.

The asterisk decides the paperwork. A 18 01 08* consignment is hazardous, so it needs a consignment note, and the records are kept for three years in England. A load of 18 01 09 is not hazardous, and it moves under a waste transfer note, kept for two years. Calling something non-hazardous does not make it harmless, however. HTM 07-01 directs blue-stream medicines to incineration or specialist treatment, and says liquid medicines should not be discharged to the sewer.

Most errors in this field arise from a narrow idea of what the word means. For waste purposes, the definition is based on hazardous properties, not on therapeutic use. HTM 07-01 and GOV.UK treat a medicine as cytotoxic or cytostatic if it is acutely toxic, carcinogenic, mutagenic or toxic for reproduction. That is much wider than oncology. HTM 07-01 itself points out that some are commonly prescribed, such as chloramphenicol. Certain hormone preparations, antivirals and immunosuppressants can also be caught.

So a general ward's blue bin can contain a cytotoxic medicine without anyone knowing it. In England and Wales, mixing the two groups is prohibited, except in homes. The solution is a formulary-level review by a pharmacist: go through the products you hold, mark those that meet the test and label the bins accordingly. Keep the list where staff can see it. Include new products as they arrive, not just when an audit comes round.

Staff safety comes with this as well. HSE guidance applies COSHH to cytotoxic drugs throughout their handling, including transport and waste disposal, and lists cleaners and contractors among those who may be exposed. Waste stored in a corridor may be sitting right where those people work.

The colour scheme in HTM 07-01 is purple for cytotoxic and cytostatic waste, and blue for other medicines. The body of a bin may be any colour, provided the lid or label matches. The physical form of the waste sets the container type. Solid and liquid medicines go in rigid containers, and medicinal waste should not be stored in loose bags. A leaking bottle of syrup in a bin of tablets creates a clean-up problem at every stage from there on.

Keep each container closed and secure, and label it to show where it came from. HTM 07-01 asks for the facility and the ward or place of origin to be identifiable. Medicines stay attractive for misuse and theft, whatever they are waiting for, so the storage area should have the same control as other pharmacy stock. Packaging containing residues is treated as medicinal waste too. Containers that are not empty and rinsed are assumed to be contaminated and classified by what they held.

Aerosols and inhalers are a separate concern. Under pressure, they do not suit the same bin as loose vials, so tell us how many you hold and in what form.

Controlled drugs are outside any routine list we price. In England, T28 allows authorised people at pharmacies and veterinary surgeries to sort and denature their own waste controlled drugs. It applies only to the 18 01 09, 18 02 08 and 20 01 32 waste groups, with limits on quantity and storage time, and it does not cover hazardous waste. GOV.UK says the wider exemption rules are expected to change in January 2027, subject to parliamentary approval. The Environment Agency's regulatory position on denaturing covers some activity at another place, and has a stated review date, so read the current version before relying on it.

HTM 07-01 notes that Schedule 1 and 2 stock controlled drugs can only be destroyed in the presence of an authorised witness, unless a T28 exemption is being used, and it asks for records of that destruction. Your accountable officer or pharmacist decides how that works in your organisation. Our part starts only when the legal steps have been completed, and each case is dealt with individually.

Pharmaceutical waste rises sharply at certain moments. A formulary change takes a product out of use, or a recall sends a batch into quarantine. A clinical trial ends and its remaining stock needs a documented destruction. A pharmacy service moves between buildings and everything has to be rechecked. These jobs often arrive with a stricter evidence requirement than routine waste, because a sponsor or manufacturer may ask for proof of what was destroyed and when.

If you have this kind of requirement, tell us early. A sponsor's destruction terms may need a specific certificate from the receiving facility, and that should be confirmed before any stock leaves. Keep trial or recalled stock in quarantine under your own system until release, with the paperwork attached. Do not add it to the general bins once the decision has been made.
