Waste Classification

EPA Waste Classification - chemical Waste Classification - Hazardous waste classification

DO I need waste classification?

In NSW, soil must be classified prior to land-fill disposal in accordance with the NSW EPA Waste Classification Guidelines 2014. Waste classification is based on the extent and type of contamination within the soil, in addition to the soil's physical and chemical properties.

The NSW EPA Waste Classification Guidelines (2014) classes waste into groups that pose similar risks to the environment and human health. The following classes of waste are defined in clause 49 of Schedule 1 of the Protection of the Environment Operations Act 1997 (POEO Act):

  • Special waste
  • Liquid waste
  • Hazardous waste
  • Restricted solid waste
  • General solid waste (putrescible)
  • General solid waste (non-putrescible).

When waste has not been pre-classified under Steps 1–4 of the Guidelines, waste generators must chemically assess their waste to determine the waste’s classification. If the waste generator does not undertake chemical assessment of the waste, the waste must be classified as hazardous waste. The chemical assessment process is based around the waste’s potential to produce and release leachates. Waste classified as hazardous cannot be disposed of in landfill and must be treated prior to disposal.
