Do you know the Clinical Waste Code? Part 8: The Black Code

Posted on the 18 October 2016 at 11:40

Having “Followed the Colour Code” to the end with Initial Medical, we take a look at the final colour in the coding system – black…

The colour black has many, often contrasting, meanings and associations. On the one hand, it is connected with power, mystery, authority, elegance, sexuality, formality and sophistication. On the other, it is linked with fear, death, evil, aggression, rebellion, control, the unknown and depression. As white is the absence of colour, black is the absorption of all colours and the absence of light.

The strength of the colour will often evoke strong emotions and it can make one feel inconspicuous while providing a sense of restful emptiness. The word is generally used with a negative charge – ‘blackmail’, ‘blacklist’ and ‘black hole’ etc.

Around the globe, the colour black conjures even more contrasting meanings. In Chinese culture, for example, every colour corresponds with one of the five primary elements, a direction and one of the seasons – black is associated with water, north and winter. In the West, black is a symbol of mourning and the colour of clothes worn during a funeral – in places such as rural Mexico, Portugal, Spain, Italy and Greece, widows traditionally wear black for the rest of their lives. In several western cultures, a black cat crossing one’s path has significant meaning as well – it is unlucky in England, but lucky in various other countries such as Italy.

Clinical Waste Code - BlackBlack is further used across nearly all industries, including in the cosmetic sector, as the colour of rubbish and waste – the ‘black sack’ having become a household name. More specifically, black is the colour allocated to mixed municipal waste in the Department of Health’s Safe Management of Healthcare Waste Memorandum, which provides a colour protocol to segregate and dispose of different waste streams effectively.

Mixed municipal waste can be very varied in contents. It includes, but is certainly not limited to:

  • Packaging
  • Tissues
  • Disposable cups and drinks cans
  • Food wrappers
  • Cut flowers (that have wilted or died)

As various different clinical waste streams are generated in cosmetic clinics, it is important to separate general municipal waste items for cost-effective waste disposal and collection procedures. As the ‘black’ waste produced is non-infectious, non-hazardous and non-toxic, in most cases it poses the lowest risk of harm to professionals, patients / customers and the environment and so it is taken to landfill for disposal. No special bins or containers are required for mixed municipal waste – just the trusty black sack.

Follow the Clinical Waste Code

As we reach the end of our blog series, we hope you are now more confident in what items are destined for which waste stream, and the colour and types of containers each require. Correct waste segregation and disposal is not only an element of regulatory compliance for providers of cosmetic procedures, but it also ensures the safety of staff and patients, while also protecting the environment and general public from unnecessary harm.

In summary:

  • Orange – Clinical and infectious waste
  • Blue – Medicinal waste
  • White – Dental amalgam waste
  • Yellow – Clinical and highly infectious waste
  • Red – Anatomical waste
  • Tiger – Offensive / hygiene waste
  • Purple – Cytotoxic and cytostatic waste
  • Black – Mixed municipal waste

Top tips:

  • Always make sure sharps waste is disposed of in rigid containers
  • Locate the disposal bins and containers as close to the source of waste generation as possible
  • Put up posters in appropriate places to remind staff about what types of waste are allocated which colour
  • Organise waste collection with a contractor you trust to understand the regulations and help you maximise compliance with ease
