Sustainability & Research

Science in Service of the Ocean

Phycogel's cultivation model is built on the premise that marine biomass production should restore, not deplete. Our research programme advances both commercial yield and ecosystem health.

Our Commitment

A Net-Positive Marine Business

Seaweed cultivation is one of the few forms of aquaculture that requires no freshwater, no feed inputs, and no arable land. When managed responsibly, it actively sequesters carbon, oxygenates coastal waters, and provides habitat structure for juvenile marine species. We have built our business around maximising these co-benefits while delivering consistent commercial supply.

No Feed, No Freshwater

Our cultivation systems draw nutrients directly from ambient seawater. There are no feed inputs, no fertilisers, and no freshwater abstraction at any cultivation site.

Carbon Sequestration

Macroalgae fix atmospheric CO₂ during growth. We measure and report carbon uptake across all cultivation sites as part of our annual environmental disclosure.

Coastal Ecosystem Support

Longline and net structures provide substrate and shelter for invertebrates and juvenile fish. We conduct annual biodiversity surveys at each site.

Zero Discharge Processing

Process water from extraction is treated and recirculated. Biomass residues after extraction are composted or returned to cultivation sites as organic amendment.

Research Programme

Advancing the Science of Red Macroalgae

Our in-house research team works alongside academic partners on strain improvement, cultivation optimisation, and novel bioactive characterisation. We publish findings in peer-reviewed journals and contribute data to open marine science databases.

01

Strain Improvement

Selective breeding and phenotypic screening programmes targeting higher polysaccharide yield, faster growth rate, and improved disease resistance in Gracilaria and Kappaphycus.

Cultivation Optimisation

Field trials and modelling work on stocking density, line spacing, harvest frequency, and seasonal rotation to maximise biomass yield per hectare while maintaining water quality.

Bioactive Characterisation

Structural and functional characterisation of sulphated polysaccharides, phycocolloids, and pigments from our cultivated species, with a focus on pharmaceutical and nutraceutical applications.
