Healthcare Waste
Healthcare Waste is waste produced during human or animal healthcare, or related research activity, and covers both Clinical Waste and Offensive Waste as defined in the Controlled Waste (England and Wales) Regulations 2012 [1] and requires specific management measures. Healthcare Waste containing radioactive materials requirements compliance with specific guidance[2].
Clinical Waste
Clinical Waste is Healthcare Waste that:
- contains viable micro-organisms or their toxins which are known or reliably believed to cause disease in humans or other living organisms
- contains or is contaminated with a medicine that contains a biologically active pharmaceutical agent
- Medicine is a drug or other preparation for the treatment or prevention of disease
- Cytotoxic and cytostatic medicine is medicine that possesses hazardous properties which are toxic, carcinogenic, mutagenic or toxic for reproduction.
- is a sharp, or a body fluid, or other biological material (including human and animal tissue), containing or contaminated with a hazardous substance
- A sharp is an item that could cause cuts or puncture wounds. This includes needles, hypodermic needles, scalpels and other blades, knives, infusion sets, saws, broken glass, and nails.
- is waste of a similar nature from a non-healthcare activity
Offensive Waste
Offensive Waste is non-infectious waste which is unpleasant and may cause offence to those coming into contact with it. It includes[3]:
- outer dressings and protective clothing e.g. masks, gowns and gloves that are not contaminated with body fluids
- hygiene waste and sanitary protection e.g. nappies and incontinence pads
- autoclaved laboratory waste.
- falls within EWC waste codes 18 01 04, 18 02 03 or 20 01 99.
Offensive waste does not include [3]:
- sharps
- anatomical waste e.g.body parts, organs or blood
- chemicals, medicines
- dental amalgam
- any waste that is infectious (i.e. a clinical waste)
Management of Healthcare Waste
The management of Healthcare Wastes is set out in Healthcare Technical Memorandum 07-01 - Safe Management of Healthcare Waste[4] which replaced the Safe Management of Healthcare Waste in 2013 [5]. Management of Healthcare Waste for regulated facilities with an environmental permit is the subject of guidance issued in July 2020 [6] by the EA which sets out appropriate measures in the following sections:
- When appropriate measures apply
- Definition of Healthcare Waste (as set out in the table below)
- Managing healthcare wastes
- General management appropriate measures
- Waste pre-acceptance, acceptance and tracking appropriate measures
- Waste storage, segregation and handling appropriate measures
- Waste treatment appropriate measures (including assessment and validation requirements)
- Emissions control appropriate measures
- Emissions monitoring and limits appropriate measures
- Process efficiency appropriate measures

Treatment and Disposal of Healthcare Waste
With regard to the table above, it can be seen that there are options for incineration and alternative treatment and in some specific cases landfill is acceptable.
Incineration
For incineration, Healthcare Waste will normally be incinerated in a High Temperature Incinerator or dedicated Clinical Waste Incinerator. Some Residual Waste EFW incinerators are able to dispose of specific Clinical Waste streams, and as a result of the COVID-19 pandemic the EA has published a Regulatory Position Statement (RPS C23) clarifying the circumstances where COVID-19 waste can be incinerated with Municipal Waste Waste (MSW) until July 2021. [8]
Alternative Treatment
There are several types of Alternative Treatments (AT) available for the treatment of Healthcare Waste all of which must demonstrate that the Healthcare Waste is 'rendered safe'Cite error: The opening <ref> tag is malformed or has a bad name. 'Rendered safe' means:
- demonstrates the ability to reduce the number of infectious organisms present in the waste to a level at which no additional precautions are needed to protect workers or the public against infection from the waste;
- destroys anatomical waste such that it is no longer generally recognisable;
- renders all Clinical Waste (including any equipment and sharps) unusable and unrecognisable as Clinical Waste;
- destroys the component chemicals of chemical or medicinal and medicinally-contaminated waste.
such treatments include:
Mechanical Treatment is also available as a pre-treatment option for any of the AT's outlined above. By pulverising, shredding, crushing etc the waste this results in a reduction of the volume of the waste by 60% plus although it does not kill any pathogens, microorganisms or disinfect equipment[9].
