Parkway Corporate Limited (ASX:PWN) has secured key approvals for its QBS Brine Management Complex (QBMC), advancing the company’s planned waste brine processing and industrial chemical production project in Queensland.

Parkway Corporate shares were trading at AUD 0.012 during the afternoon trading session on 20 August 2026. Over the past year, the company’s shares remain up 20.00%. The latest announcement highlighted regulatory approvals, development plans, and the project’s role in processing coal seam gas (CSG) derived waste brines and salts.

Parkway develops water and wastewater treatment technologies through its Industrial Operations and Process Technologies divisions, with QBMC representing a major technology commercialisation project.

Key Approvals Secured for QBMC Development

Parkway confirmed that the Western Downs Regional Council has approved the Development Application (DA) for QBMC.

The approval incorporates additional approvals from the Queensland Government State Assessment and Referral Agency, including the Environmental Authority (EA) and State-Controlled Road Access Permit.

These approvals support both the QBMC Commercial Demonstration Project (Stage 0) and the first commercial-scale development stage (Stage 1).

The company said QBMC will become the first regulated waste Facility permitted to process both CSG derived waste brine and salts while converting these waste streams into industrial chemicals.

QBMC Development Pathway and Capacity Plans

The QBMC Commercial Demonstration Project is intended to provide engineering data required to support a final Investment decision for full-scale commercial development.

Stage 0 is expected to operate at approximately one-tenth the scale of the first commercial stage.

Stage 1 represents the first full-scale commercial development, with nominal processing capacity of approximately 75,000 tonnes of contained salts in waste brine annually.

Parkway’s QBMC Master Plan includes potential staged development of up to four stages, with each stage targeting similar processing capacity over an anticipated 20-year project life.

The company said the combined capacity across four stages could potentially process lifecycle waste brines produced by Queensland’s coal seam gas industry.

Waste Brine Processing and Industrial Chemical Opportunity

Parkway said QBMC is designed to provide a beneficial use pathway for regulated waste brines by converting them into industrial chemicals.

The project’s technology platform is intended to process waste brines from multiple industries, including:

Coal seam gas and oil and gas operations.
Mining activities including coal, minerals, metals, and refining.
Municipal water treatment.
Inland desalination and wastewater treatment.
Data centre cooling water operations.

The resulting industrial chemicals are expected to include reagents used in industrial processes, minerals processing, water treatment, and agricultural applications.

Regulatory Framework Supports Beneficial Use Focus

Alongside the approval update, Parkway released a Regulatory Framework Review examining the production, storage, and disposal requirements associated with CSG derived brines in Queensland.

The review identified that saline brine presents long-term rehabilitation and stewardship challenges due to the difficulty of remediating salt once released.

Parkway said Queensland’s regulatory framework prioritises prevention of environmental harm, resource recovery, beneficial use of waste, and reducing waste disposal requirements.

The company stated that QBMC provides a potential pathway to transition CSG brine management from storage and disposal towards beneficial processing outcomes.

Strategic Location and Industry Alignment

Parkway highlighted QBMC’s location within proximity to expanding CSG developments in Queensland’s Surat Basin.

The company noted recent developments including expansion plans associated with the APLNG project and the Surat Gas Project Central, which are located near the QBMC project area.

Parkway said the project aligns with broader industry requirements for waste management, critical minerals Supply chains, and domestic chemical production.

The company also highlighted potential applications for QBMC-produced chemicals, including caustic soda and hydrochloric acid, which are used in industries such as aluminium production and minerals processing.

Development Roadmap Following Approvals

Following the approval milestones, Parkway outlined several next steps for QBMC.

The company plans to:

Finalise engineering design for QBMC-CDP.
Secure remaining Subsidiary approvals.
Progress towards early site works.
Commit to the first Parkway Hitachi Ultra-High Brine Concentration System.
Finalise project partnerships.
Develop funding arrangements for QBMC-CDP.

Parkway Group Managing Director and CEO Bahay Ozcakmak said the approvals represent a milestone following more than a decade of research, development, process development, and industry engagement.

He said the company is continuing discussions regarding opportunities to process brine from multiple sources as part of its development plans.

Investor Takeaway

Parkway Corporate’s latest update highlights approval milestones for the QBS Brine Management Complex, supporting progression towards a commercial waste brine processing and chemical production facility. The company is now advancing engineering, funding, partnership, and development activities.

Investors may continue to monitor QBMC development milestones, remaining approvals, commercial partnerships, funding arrangements, and progress towards the Commercial Demonstration Project.
