CO₂ Fixation Technology

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.

CO₂

Absorption

Fixed directly by photosynthesis

100%

Bio-based

Entirely biological process

No chemical dosing

How It Works

How ABC works, and at what scale

40%

of ocean primary production by diatoms

20%

of global net primary production

10–20 GtC/yr

carbon fixed by diatoms annually

01

Cultivate & Control

Select the optimal strain per water type; IoT+AI auto-controls light, temperature and nutrients to generate a high-density bloom.

02

Fix CO₂ & Nutrients

Photosynthesis consumes CO₂ while N, P and organics are taken into cells. Applicable to wastewater, air and flue gas.

03

Recover Biomass

Continuous harvest at target density; LCA quantifies the environmental value of recovered biomass.

04

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

Carbon

Fixed via photosynthesis and the biological pump; locked long-term as biochar and shell biomineralization → carbon credits.

Nitrogen

Instead of denitrification to the atmosphere, assimilated into amino acids within algal cells → protein feed.

Water

Simultaneous removal of nitrogen, phosphorus and microplastics — high-efficiency purification without aeration-based denitrification.

Applications

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

Scientific Basis

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.
