Goal
- Demonstrate a circular production model at an industrially relevant scale through producing high-value seaweed biomass from nutrient dense fish farm wastewater that can be used to eradicate cow methane emissions.
- Aims to build a bridge between sustainable aquaculture and cattle production with a targeted triple green benefit:
- avoided emissions in wastewater treatment
- bioremediated nutrient load from the wastewater
- optimised methane reducing cattle feed
Plan
- Wastewater nutrient load baseline mapping
- Optimise biomass yield and bioremediation performance at industrially relevant demonstration scale
- Quantify bioremediation and carbon capture potential
- Develop commercial upscaling plan
Expected results
- Evaluation of potential at an industrial demonstration scale – 50m3 / hour wastewater and 300,000L macroalgae production
- Business model innovation – ecosystem services, and mitigated production costs unlocking uptake potential – via quantification and value of bioremediated water – nitrogen (N) and phosphorous (P) removal, and quantification of biomass production cost improvements through yield and cost of goods.
- Replicability across existing and new land-based aquaculture facilities
