Our vision for sustainable, circular, organic aquacultureCircularity.
Designed as a circular aquaculture system, where water, nutrients, and biological outputs are continuously managed to maximise efficiency and minimise waste.
By integrating aquaculture production with bioresource recovery, the system enables the generation of multiple valuable outputs from a single resource stream- circularity.
This supports the development of sustainable protein systems that operate efficiently without undue environmental pressure.
❋Circular Aquaculture
Vertical Lake operates as a circular aquaculture system rather than a linear production model.
Water is continuously circulated, biological outputs are retained, and waste streams are converted into useful inputs. This approach reduces resource intensity while enabling multiple value streams from one production system.
❋ Bioresource Recovery
Aquaculture outputs are captured and repurposed within the system rather than discarded.
These are converted into:
plant nutrition products
agricultural inputs
biomaterial feedstocks
This ensures biological resources are fully utilised across the system. Zero waste.
❋ Water Stewardship
Water is reused throughout the system through gravity-driven circulation and engineered bio-filtration.
This enables:
high water re-use
reduced reliance on external sources
controlled system discharge
The result is efficient aquaculture suited to water-constrained environments.
❋Waste-to-Fertilizer
Aquaculture outputs are converted into Blue Harvest™, an organic plant food (bio-fertiliser) supporting regenerative and organic farming.
This system:
replaces waste with productive inputs
reduces reliance on synthetic fertilisers
connects aquaculture directly to agriculture
❋Climate & Land Resilience
Vertical Lake reduces pressure on land and natural resources through:
high land-use efficiency
renewable energy (solar)
efficient water and nutrient use
The system is designed for long-term resilience in resource-constrained environments.
❋ Nutrient Mining
Nutrients generated during aquaculture production are recovered and reused.
This enables:
nutrient capture within the system
reduced waste discharge
improved soil and crop support
Nutrient flows are retained and redirected rather than lost.
❋ Chemical-Free Circular Production
Nutrients generated during aquaculture production are recovered and reused.
This enables:
nutrient capture within the system
reduced waste discharge
improved soil and crop support
Nutrient flows are retained and redirected rather than lost.
