Pilbara Waste Management Facility

Pilbara Regional Waste Management Facility (PRWMF) is an integrated waste management facility that offers hazardous waste solutions to the Pilbara region. Located 36km south of Onslow, Western Australia, it consists of a green waste facility, construction and demolition facility, liquid waste facility, tyre mono-cell and a Class IV landfill.

Pilbara Environmental Service (PES) will operate the Class IV landfill on behalf of Shire of Ashburton. PES have the experience and technical expertise to innovatively manage, collect and treat hazardous, chemical, and other complex waste. We are a waste management provider of choice generating superior value and sustainable solutions for our customers, shareholders, communities, and the planet.

Key Objectives

The key objectives of the project are to:

  • Deliver sustainable resource recovery initiatives for the Onslow region;
  • Provide Best Practice waste disposal services for the Onslow region; and
  • Provide Best Practice regional hazardous waste management services.

The Pilbara Regional Waste Management Facility facilitates 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.

Funding and Project Partners

The Pilbara Regional Waste Management Facility is jointly funded by the Australian Government ($9 million), Chevron and Western Australian Government ($2 million) and Shire of Ashburton ($2 million).

The Shire, Chevron and the Western Australian Department of Jobs, Tourism, Science and Innovation are the Key Project Partners in the delivery of the project.

The Site

A site selection process was undertaken in 2013/14 utilising best practice siting and design principles to identify a preferred site for the facility. Site selection assessment criteria and constraints mapping based on environmental, social and planning factors was used to highlight potential locations. Based on the outcomes of the site selection process, a preferred location was identified within Lot 150 Onslow Road, Thalanyji. The whole site is approximately 435 hectares in size and is located approximately 36 kilometres south of the town of Onslow on Unallocated Crown Land managed by Department of Biodiversity, Conservation and Attractions. The site was subsequently subject to a desktop assessment and detailed environmental investigations, including geotechnical and hydrogeological studies which deemed it a suitable site for establishing the Pilbara Regional Waste Management Facility.

The Site

The Facility

The Pilbara Regional Waste Management Facility consists of resource recovery initiatives including a Greenwaste facility and Construction and Demolition Waste Facility to divert materials from landfill through recycling. Liquid Waste Facility including the fixation ponds will be developed to cater for industrial liquid waste.The facility also includes a Tyre monocell for the isolated disposal of these materials to encourage future recovery options. The total development footprint is approximately 67 hectares.

The Facility

A key component of the Pilbara Regional Waste Management Facility is the landfill cells. These have been designed and constructed to Best Practice landfill standards for hazardous waste (Class IV) to ensure environmental and social risks are managed appropriately. Therefore, the landfill cell consists of a double composite lining system to contain leachate and control emissions.

The facility is also operated to Best Practice landfill standards to ensure the environmental and operational management requirements are met. This includes ongoing environmental monitoring and reporting in accordance with licence requirements to ensure potential environmental impacts are mitigated and managed.

Class II waste

  • Includes all class I wastes, except for type 3 inert waste
  • Putrescible waste - waste that is likely to become putrid such as food and plant materials.
  • Type 2 special waste - biomedical waste that does not require incineration and which is approved for supervised burial.
  • Contaminated solid waste specified for class II landfills.

Class III & IV waste

  • Class III waste includes all Class I and Class II wastes plus additional contaminated solid wastes which meet specific criteria for Class III landfills and require specific license conditions.
