Research from the World Health Organisation indicates that 15% of waste from healthcare activities is considered infectious, toxic or radioactive, highlighting the importance of the correct disposal of clinical waste. This guide explores the what, why, and how of proper clinical waste management, looking into the risks associated with mishandling such waste and the strict protocols required to avoid the risks.
What is clinical waste?
Clinical waste is defined as waste materials that could pose a risk of infection or disease. Clinical waste includes items contaminated with blood or bodily fluids, infectious agents, or items used in the treatment of patients with infections. These might include swabs, bandages, and disposable medical devices. The clinical waste category is generated predominantly by healthcare providers such as hospitals, GP surgeries, nursing homes, dental practices and health clinics, or by veterinary, or research centres. It includes various subtypes such as sharps waste, cytotoxic or cytostatic waste, pharmaceutical waste, infectious anatomical waste and high-sulphate infectious gypsum waste.
Each type of clinical infectious waste requires a specific disposal strategy. For instance, steam sterilisation may be suitable for certain types, while sharps waste often requires high-temperature incineration.
How to identify clinical waste?
You can identify clinical waste by recognising the types of waste it’s made up of. Clinical waste typically includes items such as used needles, syringes, gloves, dressings, and tissues contaminated with bodily fluids, as well as medications, pharmaceuticals, and laboratory samples. If stored correctly, the waste should be segregated into colour-coded bins. Proper labelling, training and accurate bookkeeping also ensure that clinical waste is identified and managed safely. It’s best to work with a waste management specialist who is experienced in handling the segregation, transportation and disposal of clinical waste.
Why is correct clinical waste disposal so important?
Correct clinical waste disposal is important to decrease the risk of spreading disease and infection and to ensure compliance with the Healthcare Technical Memorandum (HTM) 07 01. It also helps to reduce the costs caused by improper disposal and reduce contamination risks to the environment and water.
Mishandling clinical waste can lead to severe public health hazards, underscoring the importance of strict compliance with disposal protocols. Investing in an efficient clinical waste disposal management system is crucial to safeguard both human health and the environment.
What are the different waste groups for clinical waste?
Clinical waste is categorised into different groups to enable correct handling and disposal and minimise potential risks to health and environmental impact. A colour-coded system is utilised and there is some crossover between clinical, hazardous, and non-hazardous waste. Here are the different waste groups for clinical waste displayed in a venn diagram as per the guidance in HTM 07-01 Safe and Sustainable Management of Healthcare Waste 2022:
What is the colour-coded system for clinical waste disposal?
A colour-coded system is in place to make it easier to dispose of clinical waste in a safe, efficient way. It also improves waste management procedures and saves money and time. Here is a summary of the clinical waste segregation:
- Yellow lid: This includes items like needles and syringes that are contaminated with blood or medicinal substances.
- Orange lid: This colour is designated for items contaminated with blood, including things like gloves, dressing and cleaning wipes.
- Blue lid: Reserved for pharmaceutical waste, which encompasses expired or unused medicines, excluding waste from cytotoxic and cytostatic treatments.
- Purple lid: Specifically for waste generated from hormone treatments or chemotherapy, including cytotoxic and cytostatic materials.
- Yellow bag: for highly infectious waste, not usually in the Primary Care setting.
- Orange bag: Infectious clinical waste. This includes only infectious or potentially infectious materials such as used swabs, dressings, PPE and plasters.
- Black and yellow bags: Used for non-infectious, offensive waste such as used nappies and incontinence pads which do not contain medicinal or pharmaceutical substances.
- Red lid: Allocated for anatomical waste, including human tissue.
- Black bags: Intended for the disposal of general, non-clinical waste.
What are the UK laws and regulations around clinical waste disposal?
The UK’s clinical waste disposal is regulated to protect public health and the environment. This includes section 34 of the Environmental Protection Act 1990, HTM 07-01 Safe and Sustainable Management of Healthcare Waste 2022, and the Controlled Waste Regulations 2012, along with specific guidelines for hazardous waste and the transportation of dangerous goods, highlighted by the Hazardous Waste Regulation 2005 and the Carriage of Dangerous Goods Regulations 2019.
Additionally, the Statutory Duty of Care Regulation enforces responsible waste management practices, ensuring that all steps, from storage to collection, treatment, and disposal adhere to strict safety and environmental standards.
How do you safely dispose of clinical waste bags and containers? What is meant by the safe management of clinical waste?
Each type of clinical waste is colour-coded and contained or bagged appropriately to allow for proper segregation and disposal by your waste management team. As clinical waste can be hazardous and harmful, yellow infectious waste and sharps are incinerated to mitigate the risk of contamination and spreading disease and infection, ensuring that the dangerous substances are removed. Disposal methods for other types of clinical waste such as offensive waste and orange waste bags differ. These disposal methods include adding chemicals to dissolve or neutralise the hazardous components of waste, irradiative techniques that use autoclave or microwave technology to eliminate dangerous substances, and biological processes, utilising enzymes to decompose clinical waste components.
How and where should clinical waste containers and bags be stored?
Clinical waste management requires strict processes for storage, segregation and handling. Waste cannot be stored loosely and must be kept sealed in leak-proof containers to prevent spillage and free from pests. Clinical waste should be distanced from water sources and in secured areas, with anatomical waste needing refrigeration if on-site for over 24 hours. Offensive waste should be stored securely to prevent access and procedures should be in place to minimise handling, avoiding overfilling, and storing waste by type and destination to meet regulations for and public health protection.
What is meant by the safe management of clinical waste?
The safe management of clinical waste refers to the proper handling, disposal, and treatment of waste materials most commonly generated in healthcare settings, such as hospitals, clinics, and labs. Safe management and disposal is prioritised to prevent harm to patients, staff, and the surrounding environment. This includes segregating waste, using appropriate storage/waste disposal bins, and following strict guidelines for its transport and disposal. Safe management ensures that clinical waste is disposed of in a way that minimises the risk of infection, contamination, and injury, and complies with relevant health and safety regulations and environmental protection standards.
