Common in healthcare and veterinary facilities, cytotoxic (chemotherapy) medicines must be handled and disposed of with extreme care. If you manage the waste disposal procedures of cytotoxic medicines, it’s essential to know the rules and regulations to ensure your facility stays compliant.
Failure to dispose of cytotoxic waste correctly may lead to staff and patient endangerment, as well as financial and legal consequences due to a breach of UK waste regulations.
What is cytotoxic waste?
Cytotoxic waste is a hazardous byproduct of chemotherapy treatments for cancer. This type of waste specifically includes traces of cell-killing or cell-inhibiting drugs, which can be carcinogenic, mutagenic, and toxic, making safe disposal essential for the safety of both humans and the wider environment.
Common examples of cytotoxic waste include:
- Used intravenous lines, tubing, and bags
- PPE
- Sharps used for drug administration
- Spillage kits and other absorbent materials
- Expired or leftover cytotoxic medication
- Medication packaging
- Contaminated bodily fluid waste
With this in mind, any facility handling cytotoxic medicines must comply with the UK’s strict cytotoxic waste disposal protocols.
Which UK laws apply to cytotoxic waste disposal?
Cytotoxic waste is heavily regulated under UK legislation due to its high health and safety risk. Some key pieces of legislation to be aware of include:
- The Waste Management (England and Wales) Regulations of 2006: States that cytotoxic waste requires safe segregation, containment, and documented disposal.
- Environmental Protection Act of 1990: Outlines the legal responsibility of organisations to store and dispose of cytotoxic waste safely.
- Controlled Waste (England and Wales) Regulations of 2012: Defines cytotoxic waste as clinical waste requiring specific handling and collection procedures.
- Care Quality Commission and HTM Guidance: Provides specific rules regarding clinical waste segregation and disposal in healthcare settings.
- UN and ISO standards for cytotoxic waste containers: Ensures that cytotoxic disposal containers comply with UN 3291 packaging standards and ISO 23907-1:2019 performance and testing requirements for sharps containers.
How to legally dispose of cytotoxic waste
In the UK, all cytotoxic waste must be disposed of using the purple waste stream. Ensure your team and facility stay compliant with cytotoxic waste disposal best practices by following the steps below:
1. Train all staff in purple stream rules and procedures
The purple waste stream uses clearly marked and secure clinical waste containers for disposal. The most common examples of containers include purple-lidded bins, purple sharps containers, and purple clinical waste bags.

At phs, we provide an extensive range of Clinisafe purple waste containers suitable for cytotoxic waste and have many different sizes available to suit your facility’s usage requirements.
2. Choose the correct container size for your setting
Choosing the correct size container can prevent overflow, wastage, and a higher contamination risk. Assess your facility’s needs to help you decide whether you require a low, medium, or high-volume cytotoxic waste container.

If you’re unsure which size container you need, get in touch with our team. We have plenty of experience in managing cytotoxic waste collection and disposal for a range of facilities.
3. Ensure the container meets durability and compliance standards
As mentioned, there are certain specifications that purple waste containers must meet to comply with legislation.
To ensure safe disposal, purple waste stream containers must be:
- Leakproof
- Puncture-resistant
- Durable
- Clearly labelled
For full peace of mind, our containers are made from strong, durable materials and are fully compliant with UN 3291 and ISO 23907-1:2019 standards for safe and secure containment.
4. Segregate waste into its clinical waste stream immediately
Cytotoxic waste should never be mixed with general or other clinical waste streams. Any cytotoxic waste should be segregated immediately at point of use and kept in a locked or controlled-access area until collection.
It is also vital that containers are securely closed when not in use to prevent exposure to harmful residues.
5. Work with a licensed cytotoxic waste carrier
Cytotoxic waste can only be transported, treated, and disposed of by authorised providers.

With this in mind, it is very common for facilities to seek fully serviced waste agreements with providers like phs, ensuring that their waste management needs are handled legally, safely, and swiftly.
At phs, we’ll ensure that your cytotoxic waste is safely taken away for disposal and also immediately exchange the in-situ unit.
