What is infectious waste?

Infectious waste is healthcare waste assessed as capable of causing infection if someone handles it or if it is thrown in a general bag. In UK healthcare practice it travels in an orange or yellow container, not a black sack and not a tiger-stripe bag. GOV.UK lists much human infectious bagged waste as hazardous code 18 01 03*. The producer still classifies the item.

Healthcare waste that could infect people or the environment if it is mixed with municipal refuse. Orange is the usual bag when it is not chemically or medicinally contaminated. Yellow is used when it is also chemically contaminated.

Infectious waste, clinical waste and medical waste

People use the three phrases as if they were one bin. They are not. Infectious waste is the soft stream that could cause infection: dressings, swabs, tubing and PPE assessed as infectious. Clinical waste is the wider regulated group, which also includes sharps and some medicines. Medical waste is the everyday name for healthcare-generated waste as a whole.

A needle is infectious in the everyday sense, but it is sharps waste and belongs in a UN bin. A tablet is not an infectious bag. A non-infectious pad is offensive waste if the site uses tiger-stripe.

Orange bag or yellow bag

Orange bags take infectious waste that permitted treatment sites may accept for alternative treatment, such as heat treatment, if it is not chemically or medicinally contaminated. Yellow bags take infectious waste that is also chemically contaminated. Environment Agency measures expect that yellow stream to be incinerated unless a permitted site has a specific justification.

Do not choose the colour to get a cheaper price. The assessment chooses the colour. Mixing the two, or hiding either in a black sack, is a false description.

  • Orange: infectious, no chemicals or medicines in the bag
  • Yellow: infectious and chemically contaminated
  • Neither colour: sharps, loose medicines, amalgam, tiger-stripe pads

Useful handling tips

Tie the bag when it is full enough to close, not when it is splitting. Keep it in the agreed store, not a public corridor or a waiting room. Write the producer and the date on the bag if that is what the site file requires. Leave a split or unlabelled bag for the crew to refuse rather than hiding it in another sack.

  • Used dressing from an infectious procedure: Infectious soft waste. Orange if there is no chemical contamination. Yellow if chemicals are in the waste.
  • Glove from reception, unused: Usually not infectious waste. Do not open an orange bag for it.
  • Needle, blade or bur: Sharps bin. Never an infectious sack, even if the sack is closer.

What happens after it leaves the site

Bio Waste Solutions Group is the carrier, registration CBDU642850. Infectious loads go to authorised treatment — alternative treatment or incineration, depending on the stream — not a general landfill skip. We do not operate the treatment plant. A quote is accepted only if a collection day can be kept. Household clinical waste is a council service, not this one.

Frequently asked questions

Is infectious waste the same as clinical waste?

In conversation, often yes. Infectious waste is the orange or yellow soft stream. Clinical waste is the wider group and also includes sharps and some medicines.

Can infectious waste go in a black bag?

No. A black sack is the wrong description and the wrong treatment route. Use the orange or yellow container the assessment specifies.

Can infectious waste go to landfill?

No. Authorised treatment is alternative treatment or incineration, by stream. It is not a general skip.

Is every infectious load hazardous?

GOV.UK classifies orange-bag infectious waste from human healthcare, with no chemicals or pharmaceuticals, as hazardous code 18 01 03*. Yellow chemically contaminated infectious waste is also listed as hazardous. The producer still classifies the actual load.
