RegenAqua™ macroalgal bioremediation sets a new standard in wastewater management that’s cost-effective, customised and better for the planet.

21/10/2026

At RegenAqua, the same system that removes dissolved inorganic nitrogen from treated wastewater also creates opportunities to recover and reuse the nutrients captured along the way.

Native macroalgae take up nitrogen from the water, helping to improve water quality before discharge. Once harvested, that biomass can then move into new value chains, including agricultural biostimulants, materials and renewable energy pathways. Instead of treating those nutrients as waste, the system is designed to keep them in productive use.

This is what makes RegenAqua more than a water-treatment technology. It is a circular model that links cleaner water, verified Reef Credit outcomes and resource recovery within the same system.

Our work begins with protecting water quality in Great Barrier Reef catchments, but the value of what we capture does not have to end there.

One system. Multiple environmental outcomes. Learn more at regenaqua.com.au

RegenAqua is a tertiary wastewater treatment system built around a biological process that already exists in nature.

Native macroalgae grow by using sunlight and absorbing nutrients, including nitrogen and phosphorus, from the surrounding water. RegenAqua creates managed conditions in which that natural process can be used for wastewater treatment at scale.

As the macroalgae grow, nutrients move from the water into the biomass. Harvesting that biomass physically removes the captured nutrients from the treatment system.

The result is a chemical-free approach to tertiary treatment that combines water-quality improvement with resource recovery.

Sometimes innovation is not about replacing nature. It is about designing infrastructure that works with it.

The star of our treatment system is something Queensland waterways already know very well.

RegenAqua uses native macroalgae. This grows by photosynthesis, taking up nutrients including nitrogen and phosphorus from their surrounding water to build new biomass.

That biological behaviour is the basis of the treatment process. The nutrients accumulated within that biomass leave the wastewater system with it.

Sometimes innovation isn't inventing a new biological process...It's learning how to engineer around one that nature has been running for millions of years.

In 2026, RegenAqua generated the world’s first Reef Credits from managed wastewater bioremediation at the Burdekin Shire Council wastewater treatment plant.

The first issuance represented 1,189 kilograms of dissolved inorganic nitrogen removed from wastewater before it could continue through waterways flowing toward the Great Barrier Reef.

Why does that matter?

Nitrogen is a natural and essential part of aquatic ecosystems. But in excess, dissolved inorganic nitrogen can contribute to declining water quality and place additional pressure on Reef ecosystems.

Using native macroalgae, RegenAqua captures these nutrients within growing biomass. The algae are harvested, physically removing the captured nitrogen from the wastewater system.

The outcome is then measured and independently verified before Reef Credits can be issued.

1 Reef Credit = 1 kilogram of verified DIN reduction.

Not a projected impact or hopeful success story in the future, but a measured one we've already proven.

In June 2026, the Reef Credit market reached an important milestone.

The first 1,189 Reef Credits generated through managed wastewater bioremediation were issued from Pacific Bio's RegenAqua project in the Burdekin.

It expanded what a Reef Credit project can look like. Not only changes to agricultural land management. Not only gully rehabilitation. But municipal wastewater infrastructure actively removing dissolved nitrogen before it moves further through a Reef catchment.

Eco-Markets Australia described the issuance as an important expansion of the market and an example of environmental technology creating measurable, independently verified water-quality outcomes.

For us, it was the culmination of years of science, methodology development, construction, monitoring and independent verification.

Many environmental technologies never make it beyond the research stage.

Turning an idea into a verified environmental outcome requires years of development, testing, monitoring and refinement.

RegenAqua's journey to generating Reef Credits has involved scientific research, engineering innovation, operational delivery and independent verification. The result is a project that can demonstrate measurable improvements in water quality entering the Great Barrier Reef catchment.

The recent issuance of RegenAqua's first Reef Credits represents more than a project milestone. It demonstrates that innovative water quality solutions can move beyond theory and deliver real-world environmental outcomes.

Research is important. Results are what create lasting impact.

🏆 Congratulations to Burdekin Shire Council on being recognised at the 2026 LGMA Awards for Excellence for the innovative RegenAqua Macroalgal Facility.

This award is a testament to Council's vision, leadership and willingness to embrace new approaches to wastewater treatment that deliver meaningful outcomes for both the community and the environment.

The RegenAqua Macroalgal Facility in the Burdekin is demonstrating how nature-based infrastructure can transform wastewater treatment by removing nutrients before they reach sensitive waterways connected to the Great Barrier Reef catchment. By harnessing naturally occurring macroalgae, the facility provides a low-energy, cost-effective solution that reduces operational costs while creating valuable biomass that can be reused across agriculture and industry.

We are incredibly proud that RegenAqua, developed by Pacific Bio, was selected as the technology partner for this world-first project and grateful for the trust Burdekin Shire Council placed in our team to help bring this vision to life.

This recognition belongs to the many people who contributed to the project's success, including Council staff, industry partners, contractors and the broader community.

Congratulations to Mayor Pierina Dalle Cort, Julian Tickle and the entire Burdekin Shire Council team on this well-deserved achievement.

From a regional Queensland council to a globally relevant wastewater solution, Burdekin is showing what is possible when innovation, collaboration and environmental stewardship come together.

We look forward to continuing our partnership and demonstrating how innovative, nature-based solutions can help shape the future of sustainable water management across Australia and beyond.
