Cleanfill material and cleanfills are defined as follows.

Cleanfill material

Material that when buried will have no adverse effect on people or the environment. Cleanfill material includes virgin natural materials such as clay, soil and rock, and other inert materials such as concrete or brick that are free of:

  • combustible, putrescible, degradable or leachable components
  • hazardous substances
  • products or materials derived from hazardous waste treatment, hazardous waste stabilisation or hazardous waste disposal practices
  • materials that may present a risk to human or animal health such as medical and veterinary waste, asbestos or radioactive substances
  • liquid waste.


A cleanfill is any landfill that accepts only cleanfill material as defined above.

Determining if a particular waste is acceptable in a cleanfill requires an assessment of how the waste will behave when it is placed, and the potential effects of the waste on the environment. Only waste complying with the definition of cleanfill in section 2.2 should be accepted at a cleanfill.

The Cleanfill Guide presents three lists of materials to assist in the assessment process:

  1. Acceptable Cleanfill Material
  2. Conditionally Acceptable Cleanfill Material
  3. Unacceptable Material
