End of waste codes

End of waste (EOW) codes specify outcomes that need to be achieved for a waste to be deemed a resource. It states requirements for the registered resource producer as well as conditions for the use of the resource.

View the list of current EOW codes below.

Where the use of a waste as a resource has been demonstrated to have benefits through sustainable use and negligible environmental risks, the Department of Environment, Science and Innovation (DESI) may consider developing an EOW code.

A waste producer may supply a waste as a resource under an EOW code only if they:

  • have registered with DESI
  • can comply with the requirements of the code
  • take responsibility for ensuring that the resource supplied to resource users
    • meets the criteria and quality characteristics specified in the code
    • and
    • is used in accordance with the conditions imposed on the use of the resource.

Developing EOW codes

DESI calls for submissions annually for the development of EOW codes. While submissions on all resource types are considered, the decision on whether or not to develop an EOW code is at the discretion of DESI.

Find out more about development of EOW codes, including current draft EOW codes open for public consultation.

Register to operate under an EOW code

A person must register as a resource producer to operate under an EOW code.

If a person is not registered as a resource producer, the material is deemed to still be a waste and must be continued to be managed in accordance with relevant waste management provisions under the Environmental Protection Act 1994 and Waste Reduction and Recycling Act 2011.

Users of the resource do not need to register with DESI unless the EOW code specifically requires notification under the conditions of the EOW code. Penalties may apply if the requirements and/or conditions of an EOW code are not complied with.

To register as a resource producer, or to stop being registered as a resource producer, for an EOW code, use the registered resource producer for an end of waste code notice of registration form.

If the EOW code also requires the proposed user of the resource to notify DESI, use the resource user for an end of waste code notification form.

Current EOW codes

On 8 January 2024, a minor amendment was made to the EOW Code Associated water for irrigation (including coal seam gas water) – ENEW07546918 (ESR/2019/4712) in relation to resource monitoring and management plans. This change is not a change of substance and does not adversely affect the interests of a registered resource producer or a person who is likely to receive a resource from the registered resource producer – read the notice of this amendment (PDF, 160KB).
