Clinical Waste Collection & Disposal Services

Clinical waste is a category of healthcare waste that requires specialist handling because of infection, medicinal contamination, hazardous substances, sharps or similar risks.

Not all healthcare waste is clinical waste. For example, suitable non-infectious PPE, dressings and hygiene waste can instead be classed as offensive waste.

Clinical waste disposal depends on the type of waste. Some waste is incinerated, some is sterilised, and some may go through specialist treatment before final disposal.

• Segregation: Waste is separated into the correct colour-coded clinical waste bags and containers at the point of use.
• Storage: Secure, labelled storage areas are used until collection to prevent contamination or accidental exposure.
• Collection and transport: Licensed waste carriers collect and transport clinical waste in sealed, approved containers to authorised treatment facilities.

Treatment and disposal:

• Incineration: Used for anatomical and highly infectious waste that cannot be safely treated otherwise.
• Autoclaving (steam sterilisation): Kills microorganisms before safe landfill disposal or recycling.
• Alternative treatments: Some waste streams may be chemically treated or compacted before disposal.

Clinical waste bins are used to safely collect and segregate all waste that could pose an infection or contamination risk. This includes:

• Sharps: Needles, syringes, scalpels, and other sharp instruments.
• Infectious waste: Contaminated PPE, swabs, dressings, and disposable medical instruments.
• Anatomical waste: Body parts and tissues from surgery or medical research.
• Cytotoxic and cytostatic waste: Materials contaminated by chemotherapy or other cytotoxic drugs.
• Offensive waste: Non-infectious items like used gloves, nappies, and hygiene products.
• Dental waste: Amalgam, fillings, and impression materials.

Each waste type must go in the correct colour-coded bin or bag for compliance and safety.

Some healthcare waste can go to landfill, but untreated infectious or hazardous clinical waste must not simply be disposed of in general landfill.

Treatment routes depend on the classification. For example, suitable infectious clinical waste can undergo alternative treatment or incineration, while properly segregated offensive waste can use energy-from-waste or authorised landfill routes.

To transport clinical waste in the UK you need a valid waste carrier’s licence or registration. Only licensed waste carriers are allowed to move clinical waste, whether it is a single sharps bin or multiple bags of used PPE.

Licensed carriers must transport clinical waste in suitable, sealed containers to authorised treatment or disposal facilities. Your duty of care certificate or waste transfer note records who collected the waste, where it was taken, and how it will be treated, providing a clear audit trail for compliance.

CQC-registered healthcare providers are typically required to complete a pre-acceptance audit before clinical waste is collected. This ensures waste is correctly segregated and stored. Our carrier partners carry out pre-acceptance assessments for healthcare settings. Reach out and our experts will confirm the relevant requirements for your site.

No. Under The Controlled Waste Regulations 2012, clinical waste must be stored and collected separately from general waste. Mixing clinical waste with general waste is a criminal offence under the Environmental Protection Act 1990 and can result in enforcement action.
