Hello Interloper!

In the UK, all movement of waste requires a paper trail. As such, it is important that the correct documentation is completed and handed to licenced contractors in order to fulfil legal obligations upon collection.
Hazardous waste, such as that coded yellow, requires a Hazardous Waste Consignment Note (HWCN). This will include information on the cosmetic clinic producing the waste and its premises code, as well as details of the waste itself including a description of the contents, the quantity of waste contained and information on the packaging. Codes must also be included here as required for the Department for Transport. The final documents are filled in by your service technician on the day of collection, with a signature from the relevant professional handing over the waste and again when the waste is consigned for final disposal.
At this point, ‘yellow’ clinical and highly infectious waste is sent for disposal by incineration. This is the most commonly used high temperature treatment for infectious waste but other technologies do exist such as pyrolysis and gasification. The steam generated from this heating process can sometimes be used for heating buildings near the incinerator itself.
