Before you burn

Before burning, you must explore every reasonable alternative, including:

  • Chipping
  • Mulching
  • Transporting your material to a green-waste recycling facility

You also need to minimize the amount of material to be burnt.

Under the Waste Discharge Regulation, there's a list of prohibited materials that cannot be burned in an open fire. Exclude these materials from your open fire.

Consult the Prohibited Materials Burning Factsheet (PDF, 103KB), or review Schedule 1 under the Waste Discharge Regulation.
