Dental infectious and offensive waste collection

Orange-bag infectious waste and tiger-bag offensive waste from dental practices, segregated correctly to stay compliant and avoid overpaying. UK costs.

In short: Dental infectious and offensive waste collection covers soft clinical waste from patient care: infectious waste in orange bags, sent for treatment or incineration, and non-infectious offensive waste such as gloves, bibs, masks and aprons in yellow-and-black tiger bags. It is needed by every dental practice. In the UK it typically costs £5 to £25 per bag or bin, with offensive waste usually much cheaper to dispose of than infectious waste.

Dental infectious and offensive waste collection

Most of the soft waste a dental surgery produces is low risk. Gloves, masks, bibs, aprons and paper towels from routine treatment are normally offensive waste: unpleasant but not infectious, and suitable for yellow-and-black tiger bags. Infectious waste is waste with a known or suspected infection risk, or heavily contaminated with blood or body fluids, and goes in orange bags. Getting this split right matters because infectious waste costs more to treat, and over-classifying everything as infectious is one of the most common ways practices overpay.

HTM 07-01, the Department of Health guidance on healthcare waste, sets out the colour codes most contractors use in England, with equivalent guidance in Scotland, Wales and Northern Ireland. The practice, as producer, must classify its waste correctly, describe it accurately on the paperwork and store it securely. Bags should be tied, labelled with the practice details and kept in locked bins or a secure store away from patients and the public until collection.

How much does it cost?

As a guide, UK dental practices usually pay £5 to £25 per bag or bin for infectious and offensive waste, with tiger-bag offensive waste typically the cheaper stream. Moving low-risk items out of orange bags is often the biggest single saving. See our full cost guide.

How it works

How dental infectious and offensive waste collection works, step by step

Review your waste

What goes into your clinical bags is checked, so low-risk items can move to the cheaper offensive stream.

Set up segregation

Bins and bags are placed in each surgery and labelled clearly so staff can segregate at the point of use.

Secure storage

Filled, tied and tagged bags are moved to locked bins or a secure store until collection.

Collect and document

Bags and bins are collected on schedule with the right transfer or consignment note for each stream.

Dental infectious and offensive waste collection: FAQs

What is the difference between infectious and offensive waste?

Infectious waste carries a known or suspected risk of infection, or is heavily contaminated with blood or body fluids, and must be treated or incinerated. Offensive waste is non-infectious but unpleasant, such as gloves, bibs, masks and aprons from routine treatment, and can go for energy recovery or appropriate landfill. The clinical judgement is made by the practice at the point of use.

Can offensive waste go in our general rubbish?

No. Offensive waste from healthcare should be kept separate from general municipal waste and collected in tiger bags under a waste transfer note, because it is still healthcare waste and must be described accurately. Small amounts of genuinely non-clinical waste, such as packaging and paper from reception, can go in general waste and recycling.

How long can clinical waste be stored at the practice?

There is no single fixed limit in law, but waste should be stored for no longer than is safe and practical, in a secure area, and collected before it causes odour, pest or capacity problems. Many dental practices have clinical waste collected weekly to monthly. If bins are regularly overflowing before collection, the frequency or bin size needs to change.

Do clinical waste bags need to be a particular type?

Yes. Bags for infectious waste should be of a type suitable for clinical waste and its transport, usually supplied by your contractor in the correct colour. They should be filled no more than about three quarters full, tied securely, labelled or tagged with the practice details and never compressed or decanted into other bags.
