How It Works

Excess usage of fertiliser pollutes river systems with too much phosphorus and nitrogen.
Widespread use of fertilizers in agriculture and unplanned urbanization lacking wastewater treatment are important sources of phosphorus and nitrogen in rivers​
LIQUID TREES selectively cultivates the dominant native diatom/microalgae species of a river system​​
By using pollutants as nutrients for growth, microalgae capture and fix carbon dioxide (through photosynthesis), and remove other toxic pollutants such as heavy metals.​
Microalgae have a rapid growth rate in highly polluted water, growing >2x per day leveraging rivers as a bioreactor​
As microalgae grow, they release oxygen into the river, improving low-oxygen zones while treating water​
LIQUID TREES cultivates diatoms/microalgae that start sinking​ once pollutant density is too low for replication​
LIQUID TREES microalgae sink into the riverbed​
Deposition of clay, silt, sand, pebbles, and organic matter in the riverbed help to deeply bury microalgae​
LIQUID TREES periodically collect water and sediment samples from the river to monitor the bioremediation process and validate & verify water quality and pollutant removal
LIQUID TREES shares results with auditors and regulatory agencies

How we measure carbon

Modelling and Simulation

Liquid Trees develops models using satellite imagery, field data, LiDAR imaging, and other remote sensing data to identify key parameters used to estimate carbon fixation and sequestration.

Modelling and simulation

Assess the Baseline

We develop machine learning models for our river bioremediaton and carbon removal projects. Using satellite images, field measurements, and simulation, we track microalgae biomass concentration, nutrients load, and other parameters along the river. Liquid Trees use a dynamic baseline updated quarterly according to seasonal changes on the river to compare the current status of the river without the project.

Assess the Baseline

Estimate Soil Organic Carbon

Microalgae possess remarkable capabilities in converting carbon dioxide into oxygen through photosynthesis while fixing carbon in their biomass, making them invaluable in combating climate change. We use models to estimate the contribution of diatoms to organic carbon in the riverbed soil. We use field data to calibrate the models according to the specific conditions at each target river.

Estimate Soil Organic Carbon

Monitor River Bioremediation and Carbon Sequestration

Liquid Trees develops a specific river monitoring strategy for each project to assess the spatial and temporal evolution of water and sediment parameters during the algal bioremediation.

Monitor River Bioremediation and Carbon Sequestration

Plan New River Bioremediation Projects

Liquid Trees is open to use these tools for the development of new river bioremediation projects, restoring water quality and sequestering carbon in tropical and subtropical regions around the world.
