The Liquid Tree, Serbia's first urban photo-bioreactor, is a groundbreaking solution to the problem of air pollution. Developed by scientists at the University of Belgrade, this innovative technology uses microalgae to bind carbon dioxide and produce oxygen, effectively reducing greenhouse gas emissions and improving air quality.
Belgrade is the fourth most polluted city in Serbia, with two large coal power plants nearby that are among the top 10 dirtiest plants in Europe. The country ranked as Europe's fifth most polluted country in 2019, with an average PM 2.5 in air pollution, according to the IQAir's World Air Quality Report. The Liquid Tree is a much-needed invention in a highly polluted nation like Serbia.
The Liquid Tree contains 600 liters of water and uses microalgae to bind carbon dioxide and produce pure oxygen through photosynthesis. According to Dr. Ivan Spasojevic, one of the authors of the project from the Institute for Multidisciplinary Research at the University of Belgrade, the microalgae replaces two 10-year-old trees or 200 square meters of lawn. The Liquid Tree is a sustainable alternative to traditional methods of greening urban environments, and it operates during the winter, making it an ideal solution for cities with limited space and heavy pollution.
Innovative climate technology like the Liquid Tree is key to reducing greenhouse gas emissions and adapting to the impacts of climate change. The Technology Executive Committee (TEC) of the UN Climate Change is fostering the use of innovative climate technology to combat climate change. Artificial intelligence of things (AIoT) solutions are integral to tackling some of the challenges associated with carbon management. The coming decade will be decisive in the fight against climate change, and innovation will play a crucial role in achieving net-zero emissions by mid-century.
The Liquid Tree is a testament to the power of innovation and the importance of investing in sustainable technologies. As we continue to face the challenges of climate change, we must look to solutions like the Liquid Tree to create a cleaner, healthier future for all. The Liquid Tree represents a significant step forward in the fight against air pollution and climate change, and its potential impact cannot be overstated.
There are many innovative technologies being developed to combat climate change. Other than this liquid tree, Wind and solar power are among the most effective renewable technologies that can make the deepest cuts to net emissions in the short term.
