Waste Management in the Dental Practice

How to correctly classify and dispose of hazardous infectious-risk and chemical-risk healthcare waste produced in a dental practice, according to Presidential Decree 254/2003 and Legislative Decree 152/2006.

Waste produced in a dental practice falls almost entirely under the category of special waste, regulated by Legislative Decree 152/2006 and, more specifically for the healthcare sector, by Presidential Decree 254/2003. The regulation distinguishes two macro-categories particularly relevant to everyday practice: hazardous infectious-risk waste, contaminated by blood or biological fluids — extracted teeth, syringes, scalpel blades, burs, gauze, cotton, gloves, masks, disposable barrier drapes — and hazardous chemical-risk waste, including expired medications, mercury amalgam residue, spent disinfectants and, where still in use, developing and fixing solutions for analog X-rays.

Infectious-risk waste is identified with EWC code 18.01.03* and must be collected in dedicated rigid containers — those for sharps and needles have a structure specifically designed to prevent accidental punctures — fitted with an inner bag well-secured to the rim. Presidential Decree 254/2003 establishes that temporary storage of these containers must take place in a dedicated space, accessible only to authorized staff, and sets a maximum storage limit of 5 days from container closure when total volumes exceed 200 liters, precisely to avoid prolonged accumulation of potentially infected biological material within the practice.

Final disposal of infectious-risk waste must occur exclusively through authorized incineration facilities within the region, or alternatively through dedicated sterilization plants, never together with ordinary municipal solid waste except for specific exceptions provided by the regulation itself. Chemical-risk waste, on the other hand, follows differentiated disposal routes based on its specific nature: dental amalgam, for example, requires dedicated amalgam separators installed on the dental unit's drains, precisely to prevent residual mercury from ending up in wastewater.

In practice, correct waste management requires that every container be unambiguously labeled with the nature of the material it contains, and that the practice rely on an authorized company for periodic collection, which issues a document at the end of disposal attesting that it took place according to legal requirements — a document that, as with sterilization traceability, must be carefully kept because it constitutes proof of the practice's regulatory compliance in case of inspection.

On Oralzon you'll find containers for infectious-risk healthcare waste in various formats, including rigid versions for sharps and needles, along with consumables designed to reduce waste production through correctly sized disposable solutions.
