Declaration and disposal of hazardous and radioactive waste #

For infectious waste: see separate guidelines (in Norwegian)

  1. Log on to avfalldeklarering.no (in Norwegian) and fill out the declaration. If you need a user account, see Access to avfallsdeklarering.no (in Norwegian).
  2. Order waste collection through the order system. Write down the different declaration numbers in the order. You can also enclose a copy of the declarations with the order. This works as a failsafe to make sure the correct unit is invoiced. Enter "Norsk Gjenvinning AS" as "Provider" and the correct project number.
  3. Print the declarations from avfallsdeklarering.no and deliver these to the driver when the waste is collected. 

The declarations will have the status "Sent declarations" on avfallsdeklarering.no until they have been controlled and, if necessary, corrected by the waste recipient. A waiting period of 7 days will follow before they are submitted to the authorities. At this point, the declarations will change status to "Completed declarations". In addition to the invoice, this is your documentation for the disposal of the hazardous waste. 

Regarding disposal of radioactive waste: Norsk Gjenvinning AS can transport, but not temporarily store, radioactive waste. Schedule the delivery with the establishment that receives your radioactive waste before you order collection/transport from Norsk Gjenvinning AS.

Price list and packaging overview #

  • Price list (you have to be logged on to Innsida). Transport and empty packaging is included in the unit prices. To avoid running out of packaging: Order packaging together with collection of hazardous or infectious waste.

Orders are made through the order system

Note: For each declaration, the weight is rounded up to the nearest kg. This affects the price. You should therefore consider which types of waste can be safely declared and disposed of together. One declaration can apply for several containers (bottles, cans, etc.). All containers must be labelled, as described under Chemical waste.

How to fill out a declaration on avfallsdeklarering.no #

See the dedicated instructions from avfallsdeklarering.no (in Norwegian)

Here you can find information on how to declare hazardous waste 

Description of the waste

  • Enter the waste product number and EAL code
    • Suggested hits will appear when you start typing in the fields. Example: A search for "inorganic" under "Waste product number" will produce hits like "acids, inorganic", waste product number 7131. A search for "sulphuric acid" under EAL codes will produce hits like "sulphuric acid and sulphurous acids", EAL code 060101.
  • Describe the waste under "Description". You should enter the names of the chemicals, if possible
  • You can also upload attachments, if necessary. For highly reactive chemicals (waste product numbers 7122 and 7123), always enclose the safety data sheet. Such chemicals must be declared separately. 

Transport classification

  • Select "ADR" under "Transport classification"
    • Select the correct hazard labels under "ADR classification" (both main classification and additional classification (if applicable).
    • Under "ADR classification, select the main classification.
  • Enter the UN number, packaging category and any additional information.

You will find information about filling out the fields under "Transport classification" via the support material, as described above. Note that the UN number may be specified as "FN-nummer". Packaging category might be specified as "Forpakningsgruppe". 

Waste receipt and transporter

  • ”Select waste recipient”: Select “Sorteringsanlegg - Trondheim - Norsk GjenvinningStarting november 2019, employees in hospital buildings should also select Sorteringsanlegg - Trondheim - Norsk Gjenvinning.
  • "Transporter": Select "Avfallsmottak".

Summary and submission

  • Click on "Signer og send deklarasjon" when the declaration is complete. By signing, you confirm that the contents are in accordance with the declaration. You must also remember to write the declaration number on the packaging.
  • Any discrepancies in the declarations will be listed in red on the right side of the screen.
  • Note that you have to order waste collection through the order system.

If there is any doubt about correct declaration, this must be clarified with the waste recipient. 

Access to avfallsdeklarering.no #

You need a user account to be able to declare hazardous and radioactive waste through avfallsdeklarering.no (in Norwegian). Please contact:

Collection/transport #

From 1 November, 2018, NTNU has a purchase agreement with Norsk Gjenvinning AS (in Norwegian).

  • Trondheim: Norsk Gjenvinning AS has established routes every Thursday, but you can order collection on other days as well (additional fees apply). 
  • Ålesund and Gjøvik: Collection upon request.

Order collection through the order systemIf your unit has a collection agreement with the waste recipient, you do not have to order collection. 

Glossary #


European agreement about international road transport of hazardous waste. For more information, see the “ADR/RID 2017 Regulation of land-carriage of hazardous goods (in Norwegian)” 

Waste product number

A 4-digit national code for classification of hazardous waste. You can find the codes in the instructions from the Norwegian Association for Hazardous Waste (in Norwegian) (NFFA). The instructions from NFFA can be ordered or downloaded digitally. 


Avfallsdeklarering.no is an electronic solution for declaration of hazardous and radioactive waste. The solution is administered by the Norwegian Environment Agency and The Norwegian Radiation Protection Authority. 

EAL code

The EU standard for classification of waste (6-digit code). The most frequently used EAL codes are listed in the table for handling of waste (in Norwegian). Your unit can also use the instructions from NFFA (in Norwegian).

Packaging category

Substances and substance categories that are defined as hazardous goods are labelled with their packaging category, based on the danger classification of the substance or substance category. There are three packaging categories: 

  • I – Very hazardous substances
  • II – Medium hazardous substances
  • III – Less hazardous substances

This classification does not apply for danger classifications 1, 2, 5.2, 6.2, 7 and the self-reactive substances in danger classification 4.1 (see Danger classification below). Packaging approved for transport of hazardous goods is labelled with the packaging category it is suited for. The packaging is labelled X, Y or Z.

Packaging labelled X can be used for substances in packaging category I, II and III.

Packaging labelled Y can be used for substances in packaging category II and III.

Packaging labelled Z can only be used for substances in packaging category III.

Nevertheless, packaging must always be assessed with regards to its resistance to the content's chemical properties. For instance, steel packaging should not be used for acids or acid solutions. Information about which packaging category different products belong to can be found in the Table for handling of waste (in Norwegian). You can also use the instructions from NFFA (in Norwegian).

Danger classification

When disposing of hazardous and radioactive waste, the external packaging must have hazard labels with the correct danger classification. Hazard labels (stickers) can be ordered from the waste recipient. Hazardous goods transported by road (ADR transport) are divided into the following classes:

  • Class 1: Explosives

  • Class 2: Gases

  • Class 3: Flammable liquids

  • Class 4.1: Flammable solids

  • Class 4.2: Spontaneously flammable substances

  • Class 4.4: Substances developing flammable gas when in contact with water

  • Class 5.1: Oxidising substances

  • Class 5.2: Organic peroxides

  • Class 6.1: Toxic substances

  • Class 6.2: Infectious substances

  • Class 7: Radioactive material

  • Class 8: Corrosive substances

  • Class 9: Various hazardous substances and objects. Note that lithium now has a separate hazard label, which should be used for disposal of lithium batteries.

Information sheet

Hazardous biological materials and chemicals that do not have a safety data sheet, should have an information sheet. Information sheets contain information about hazardous properties, preventive safety measures and first aid treatment etc. For more information, see the Regulation of the performance of work, ch. 2 (in Norwegian). Information sheets are located in the NTNU substance index (in Norwegian) (ECO-Archive). 

Safety data sheet

Safety data sheets contain information about hazardous properties, first aid measures, and handling and storage. Safety data sheets also contain information about UN number, danger classification and packaging category. The latter is specified in subsection 14, and is important with regard to the disposal of chemicals. For more information, see the Regulation of the performance of work, ch. 2 (in Norwegian). Information sheets are located in the NTNU substance index (in Norwegian) (ECO-Archive). 

UN number (FN-nummer)

All hazardous substances or hazardous substance groups with equal properties are assigned a 4-digit UN number. The numbers are determined by a UN expert committee. You can find the numbers in the instructions from NFFA (in Norwegian) (see the section Waste product number). UN numbers are specified in the declaration of hazardous waste.
