Delorean moves Salisbury bioenergy plant towards first gas

SA1 receives approval to begin waste operations

Delorean Corporation Limited (ASX:DEL) has cleared a regulatory gate that stood between its SA1 Salisbury bioenergy project and commissioning. The South Australian Environment Protection Authority has issued the operational licence allowing the Edinburgh Parks facility to receive and process organic waste.

The licence permits a staged start rather than an immediate full-scale operation. Delorean plans to initially accept packaged organic waste to support controlled commissioning, then expand to suitable liquid and solid organic waste streams as the plant progresses towards commercial operations and meets the licence conditions.

Construction reaches 90% as first biomethane approaches

Construction is approximately 90% complete, according to the announcement, putting the project into its next practical test: receiving feedstock, beginning biological commissioning and producing gas. The approval follows an earlier SA1 completion update that reported construction had passed 85% completion.

Delorean said SA1 is progressing towards first renewable gas, or biomethane, injection into the Adelaide gas network. The announcement does not provide a specific date for first waste acceptance, first injection or the start of commercial operations, leaving commissioning performance and timing as the next milestones for shareholders to assess.

Facility targets multiple revenue streams from organic waste

Once operational, SA1 is designed to process 70,000 tonnes of commercial, industrial and municipal organic waste each year. The facility is expected to produce 210 terajoules of renewable gas annually, alongside 6,000 tonnes of biogenic food-grade liquid carbon dioxide, environmental credits and biofertiliser.

Those outputs give the project more than one potential source of value, although the announcement contains no updated cost, funding or operating guidance. Delorean has previously received an ARENA grant milestone for the Salisbury plant, while the latest filing focuses on the licence and operational pathway rather than financial performance.

Salisbury positioned as template for future projects

Delorean describes SA1 as a template for its wider near-term infrastructure portfolio. The company says its NSW1 and VIC1 facilities are targeted to enter construction in FY2027, but the Salisbury plant now carries the immediate burden of demonstrating that the development model can move from construction into operating assets.

The project was also named the sustainability category winner at the 2026 Australian Financial Review Energy Awards on 13 October. That recognition adds industry visibility, but the more consequential evidence will come from whether waste receival, biological commissioning and network injection proceed as planned.
