Algal Bloom Capture (ABC)
A wholly new carbon-negative technology that controls and harnesses algal bloom — the mass proliferation of microalgae — to fix CO₂ and surplus nutrients at the same time.

Cultivate & Control
Select the optimal strain per water type; IoT+AI auto-controls light, temperature and nutrients to generate a high-density bloom.
Fix CO₂ & Nutrients
Photosynthesis consumes CO₂ while N, P and organics are taken into cells. Applicable to wastewater, air and flue gas.
Recover Biomass
Continuous harvest at target density; LCA quantifies the environmental value of recovered biomass.
Resource & Credits
Convert biomass into feed, fertilizer and bio-materials; fixed carbon becomes eligible for carbon credits.
Restoring Three Cycles
ABC delivers three environmental values — carbon, nitrogen and water — simultaneously
Fixed via photosynthesis and the biological pump; locked long-term as biochar and shell biomineralization → carbon credits.
Instead of denitrification to the atmosphere, assimilated into amino acids within algal cells → protein feed.
Simultaneous removal of nitrogen, phosphorus and microplastics — high-efficiency purification without aeration-based denitrification.
Where it applies
Aquaculture
Feed supply and water quality management for shellfish and crustacean farming
Water treatment
Purification and resource recovery for eutrophic lakes and wastewater
Agriculture
High-performance organic fertilizer derived from algal biomass
Flue gas treatment
CO₂ emission reduction at plants and power stations
The evidence behind it
Algal Bloom Capture (ABC) is Novelgen’s own technology, integrating and optimising mechanisms already established in the peer-reviewed literature: photosynthetic CO₂ fixation by microalgae (1 t of biomass ≒ 1.83 t CO₂), assimilation of nitrogen and phosphorus, and nutrient recovery from flue gas and wastewater. Because individual treatment rates, yields and removal ratios depend on the deployment environment and on the strain or blend used, representative figures are presented as values demonstrated in our own trials.
