Waste and amalgam waste
Open in the coursewith narrated slides, a checklist to tick off and a quiz
At a glance
- Close to where it arises. Waste is collected as close as possible to where it arises, to keep the contamination risk small.
- Straight into the container. Needles, blades and ampoule remains go at once, at the workplace, into puncture-proof, sealed, closable containers. Full containers are closed and never opened again.
- AWG, records, EDM. Hazardous waste falls under the Waste Management Act and the waste records regulation, with consignment notes and registration in EDM.
- SN 35326 gn. Separator cartridges, strainer residues, empty capsules and amalgam remains fall under this code and go to a licensed waste company.
- Seven years. Waste records and consignment notes are kept for at least seven years.
In detail
Collecting and disposing
- Waste is collected as close as possible to where it arises § 19(1) HygV.
- Cannulas and other sharp or pointed objects, such as needles, ampoule remains, lancets and scalpel blades, go straight after use, at the workplace, into puncture- and break-proof, liquid-tight, firmly closable, opaque containers. Full containers are closed tight and never opened again § 19(2) HygV.
- Waste containers are stored so that others aren't put at risk and they can't be misused. Bins aren't emptied into other bins, and waste isn't pressed down by hand. The local council's disposal rules apply § 19(3) HygV.
Waste law
The Waste Management Act 2002 (AWG 2002) and the Waste Records Regulation 2012 apply, in particular the consignment notes for hazardous waste and registration in the EDM portal, as does ÖNORM S 2104 on waste from medical settings § 19(4) HygV. The consignment notes are also part of the hygiene records § 5(2)(c) HygV.
What goes where
Annex 1 sorts a dental practice's waste into three groups. The codes come from the waste list of the Waste List Regulation 2020 (Abfallverzeichnisverordnung 2020) (ÖZÄK-HygV 2025, Annex 1):
| Group | Examples | Code |
|---|---|---|
| no danger, inside or outside a medical setting | general waste, bulky waste, disinfected waste | SN 91101, 91401, 97102 |
| a danger only in a medical setting; not disposed of as hazardous waste | no injury risk: swabs, gloves, syringes without needles, cotton rolls, even when bloody | SN 97104 |
| injury risk: needles, scalpel blades, ampoule and cartridge remains, root canal instruments | SN 97105 | |
| a danger outside a medical setting too; disposed of through a licensed waste company | amalgam: separator cartridges, strainer remains, empty mixing capsules, amalgam remains | SN 35326 gn |
| disinfectants; fixer and developer baths | SN 53507 g; SN 52707 g, 52723 g | |
| cytotoxic medicines and medicines containing heavy metals | SN 53510 g; SN 53501 |
Waste with an injury risk goes to authorised collectors or processors or to a hazardous-substance collection point; for waste that poses a danger, disposal records must be kept. Disinfectants and fixer and developer baths may only go into waste water as the regional water rules allow. Waste records and consignment notes for hazardous waste must be kept for at least seven years under § 17 AWG 2002 and § 12 of the Waste Records Regulation (Annex 1).
Amalgam separators
Where amalgam is used or removed, the practice needs a separator with at least 95% retention, maintained as the manufacturer says, and amalgam waste may only go to an authorised waste company (Art. 10 Regulation (EU) 2017/852; lesson 6.1).
Checklist
- There are sharps containers at every workplace.
- Full containers are closed and never reopened.
- We are registered in EDM and get consignment notes for hazardous waste.
- Amalgam waste goes as SN 35326 gn to a licensed waste company.
- We keep waste records and consignment notes for seven years.
Quiz
Under which waste code do amalgam separator cartridges fall, according to Annex 1?
- SN 53507 g
- SN 35326 gn
- Household waste
- SN 52707 g
Show the answer
The answer is B: SN 35326 gn. Mercury and mercury-containing residues, including amalgam separator cartridges, strainer remains, empty mixing capsules and amalgam remains, fall under SN 35326 gn (ÖZÄK-HygV 2025, Annex 1).

Not legal advice. What counts is the acts and regulations in the Federal Legal Information System and the Austrian Dental Chamber's regulations (read on 7 October 2026). The health minister's regulation with the criteria from 2028 (§ 9b(2) GQG) had not been issued on that day. Not covered are insurer contracts, billing, data protection in detail and the employer's duties under the Worker Protection Act in detail; there is a separate course on those at aschg.globalapps.top.
