The Pilbara Regional Waste Management Facility, just 40km from Onslow, is a new regional waste management facility for Australia's North West.

Construction of the waste management facility commenced in 2019 and is expected completion in February 2021 and made possible through funding by the Australian Government through the Building Better Regions Fund, the Chevron and the Shire of Ashburton.

One of only three Class IV facilities outside of Perth Metro area and the only such facility within North West Australia, it will accept Class III and IV waste, including waste from the mining, industrial and oil and gas sectors across the wider Pilbara region. The integrated facility will also consist of a Greenwaste facility, Construction and Demolition Waste Facility, Liquid Waste Facility, Tyre Mono-cell and Class IV landfill. 

The development of the Pilbara Regional Waste Management Facility will also facilitate economic diversification and growth by significantly reducing the cost of managing waste, including hazardous materials for the mining, oil and gas, government and other industries throughout Onslow, the Pilbara Region and beyond.

Once opened, the PRWMF will accepts a wide range of waste from the general public, commercial operators, and local, regional, state and federal government organisations.

  • Putrescible waste - waste that is likely to become putrid such as food and plant materials.
