Belgrade's fight against breathing: the growth of the "liquid tree"
Belgrade, the capital of Serbia, faces a serious problem of air pollution. Located between two coal-fired power plants, the city suffers from high levels of pollution. But Belgrade is not giving up. In his fight for clean air, he uses a unique weapon: Liquid Tree.
These are not your typical leafy giants. Liquid Tree is an innovative bioreactor that is essentially a solar-powered aquarium, filled with microscopic life forms called microalgae. Imagine a smooth translucent column filled with 600 liters of water and glowing with a bright green light. This liquid tree is a testament to Serbia's ingenuity.
The power of microalgae
The secret of Liquid Tree lies in the algae that live within it. These tiny organisms are nature's best air purifiers. Through photosynthesis, like leaves, they absorb carbon dioxide, a major air pollutant, and release pure oxygen.
However, the benefits of microalgae include: In other words, it is an efficient machine. Studies show that trees can capture CO2 10 to 50 times more efficiently than trees.
City warrior
Liquid wood offers clear advantages in urban environments. Like many cities, space for planting trees is limited in Belgrade. These bioreactors can be placed strategically along busy streets to maximize their impact on polluted airflow. Unlike trees, they are not affected by harsh winter conditions and can function all year round.
In addition to air purification
The benefits of liquid wood go beyond air purification. The by-product of algae growth is nutrient-rich biomass. It can be used as fertilizer in urban gardens to create a closed green system. Additionally, the water used in the bioreactor can be reused for plant irrigation.
Innovation through green light
The liquid tree project, the brainchild of Serbian scientist Dr. Ivan Spasojevic, is still in its early stages. Although they cannot replace forests, they offer a promising solution for urban areas struggling with air pollution. Belgrade's Liquid Tree is a beacon of hope and a testament to human ingenuity in the fight for a cleaner, greener future. Their sleek forms that grace the streets and glow with the power of microalgae are a reminder that even the most complex problems can find surprisingly elegant solutions.
