Pacific Bio

What Pacific Bio does

Pacific Bio (legal entity Pacific Biotechnologies (Australia) Pty Ltd) is an Australian biotechnology company headquartered in East Melbourne, Victoria, founded in 2006, with 51-100 employees. The company has built a nature-based wastewater treatment platform around native macroalgae cultivation, commercialized under the RegenAqua brand. RegenAqua systems treat point-source wastewater discharge by removing nitrogen and phosphorus through biological uptake by macroalgae, with documented performance of 99-100% Ammonia-N removal, 95-98% Soluble Reactive Phosphorus removal, near-zero Oxidised Nitrogen in longer-residence-time ponds, and 90-95% reduction in total nitrogen over 30+ months of continuous operation at a Sydney Water facility in Picton.

The core RegenAqua platform generates three downstream product lines from harvested macroalgae biomass: PlantJuice (an agricultural biostimulant), Pacific Bio Energy (advanced biofuels including biocrude, biomethane, and bioethanol), and ReefAsta (nutraceutical extracts). The system is also positioned to generate Reef Credits and nutrient offsets in Australian environmental markets, creating a transaction-fee layer on top of infrastructure revenue.

Pacific Bio sells exclusively through direct enterprise sales to municipal water utilities and regional councils in Australia, with confirmed deployments at Sydney Water (Picton, New South Wales) and Burdekin Shire Council (Queensland). Revenue is generated via managed-service infrastructure contracts, biomass product sales, and Reef Credit transactions. The Burdekin facility won the 2025 Australian Water Association Queensland Water Award for Regional Infrastructure Project Innovation, and the technology has been featured internationally by the Water Environment Federation. The company is privately held with no disclosed funding rounds or revenue figures in the available source material.

Revenue model

1. Wastewater Treatment Infrastructure: Pacific Bio deploys its RegenAqua macroalgae-based wastewater treatment systems for municipal water utilities and councils, generating revenue through infrastructure deployment, long-term service contracts, and operational partnerships. The technology replaces conventional wastewater treatment systems at lower cost.
2. Biomass Products (Biostimulants & Biofuels): Harvested macroalgae biomass is processed into PlantJuice (biostimulant for agriculture) and Pacific Bio Energy (biocrude, biomethane, bioethanol), creating secondary revenue streams from the treatment process outputs.
3. Reef Credits & Nutrient Offsets: The RegenAqua system generates Reef Credits and nutrient offsets by removing nitrogen and phosphorus from wastewater, creating environmental market revenue for facility operators.

Core offering

Pacific Bio deploys and operates nature-based wastewater treatment infrastructure (RegenAqua) that uses native macroalgae to clean point-source wastewater discharge, producing reusable water, Reef Credits, and harvested biomass. The harvested biomass is processed into commercial outputs including PlantJuice biostimulants for agriculture, Pacific Bio Energy biofuels (biocrude, biomethane, bioethanol), and ReefAsta algal nutraceuticals.

Product overview

Pacific Bio offers a portfolio of products built around macroalgae technology for environmental applications. The core product is RegenAqua, a wastewater treatment platform that uses native macroalgae for carbon sequestration and nutrient removal from point source discharge. This platform generates outputs that feed into three sub-brands: PlantJuice (biostimulants for agriculture), Pacific Bio Energy (biofuels including biocrude, biomethane, and bioethanol), and ReefAsta (nutraceuticals from algal extracts).

Partnerships

Two partnerships are on record, tiered core.

• Sydney WatercoreImplementation/ SI/ Consulting Partner · 1 January 2025Sydney Water partnered with Pacific Bio to deploy the RegenAqua Facility at Picton. Over 30 months of operation, the facility delivered proven, nature-based treatment performance: 99–100% removal of Ammonia-N, 95–98% removal of Soluble Reactive Phosphorus, near-zero Oxidised Nitrogen, and 90–95% reduction in nitrogen. Emma James, Segment Lead at Sydney Water, presented these results at the 2025 AWA NSW Conference.
• Burdekin Shire CouncilcoreImplementation/ SI/ Consulting Partner · 1 January 2025Burdekin Shire Council deployed the world's first RegenAqua Macroalgal Bioremediation Facility, developed in partnership with Pacific Bio. The facility won the 2025 Australian Water Association Queensland Water Award for Regional Infrastructure Project Innovation. After cleaning wastewater and absorbing nitrogen and phosphorus, the nutrient-rich algae is used as farm fertiliser. Other reef councils in Queensland have expressed interest in the technology.

Scale indicators4 records

Recent moves6 records

Expansion highlights6 records

Broad incumbents

• Veolia: Global leader in water and wastewater treatment services for municipal and industrial customers. Veolia is a broad incumbent that competes with Pacific Bio in municipal wastewater, but operates at vastly greater scale and with conventional rather than nature-based technologies.
• Xylem: Major water technology company serving municipal utilities with treatment, transport, and monitoring solutions. Xylem's Evoqua acquisition gave it scale in wastewater treatment infrastructure, making it a broad incumbent comparable to Pacific Bio's municipal customer base and infrastructure deployment model.
• Corbion: Dutch ingredient company with a significant algae-based ingredients business (AlgaPrime DHA) supplying feed, food, and nutraceutical markets. Corbion is a broad incumbent comparable to Pacific Bio's ReefAsta nutraceutical sub-brand and its algae-based bioproducts approach.

Emerging players

• AlgaEnergy: Spanish microalgae biotechnology company producing agricultural biostimulants, animal nutrition, and cosmetic ingredients from microalgae. AlgaEnergy is a direct emerging peer to Pacific Bio's PlantJuice and ReefAsta sub-brands, both leveraging cultivated microalgae for high-value bioproducts.
• Heliae Development: US-based algae biotechnology company focused on soil health and agricultural biostimulant products derived from microalgae. Heliae is a comparable emerging player to Pacific Bio's PlantJuice product line, both selling algae-based biological inputs to agriculture.
• PhycoTerra: US-based producer of soil amendment and biostimulant products derived from microalgae. PhycoTerra is a direct emerging peer to Pacific Bio's PlantJuice biostimulant business, both targeting regenerative agriculture with algal-based biological inputs.
• Seabin: Australian environmental technology company deploying water-cleaning devices in marinas and waterways. Seabin is a comparable Australian emerging player in nature-based and technology-enabled water remediation addressing point-source pollution.
• Origin Clear: US-based water treatment technology company focused on decentralized and modular water reuse for industrial and municipal customers. OriginClear is an emerging peer comparable to Pacific Bio's modular municipal infrastructure approach.
• LanzaTech: US-based carbon recycling company converting waste gases into biofuels and chemicals via biological processes. LanzaTech is comparable to Pacific Bio's Pacific Bio Energy sub-brand in its biology-to-fuels conversion approach, though Pacific Bio uses macroalgae biomass rather than waste gases as the input.

Regional players

• Cleanaway Waste Management: Australia's largest waste management company, providing solid waste, liquid waste, and industrial services to municipal and industrial customers. Cleanaway is a regional peer operating in adjacent Australian environmental services and addressing similar municipal and industrial waste streams.
