Belgrade has an innovative tool in the fight against dirty air - this so-called "liquid tree".

Belgrade, the capital city of Serbia, has implemented an innovative tool in the fight against air pollution. It is called the "liquid tree", and it is Serbia's first urban photo-bioreactor. This solution aims to tackle greenhouse gas emissions and improve air quality in the city.

The liquid tree is a system that 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 in the liquid tree can replace two 10-year-old trees or 200 square meters of lawn.

This is because both trees and grass perform photosynthesis and bind carbon dioxide. However, microalgae are 10 to 50 times more efficient than trees in doing so. The liquid tree system aims to fill urban pockets where there is no space for planting trees, not to replace forests.

Belgrade is the fourth most polluted city in Serbia, largely due to the two large coal power plants nearby. These plants are among the top 10 dirtiest plants in Europe, according to the European NGO Health and Environment Alliance (HEAL).

In 2019, Serbia ranked as Europe's fifth most polluted country with an average PM 2.5 in air pollution, according to the IQAir's World Air Quality Report. Additionally, a report from December 2019 claimed that Serbia had Europe's worst per capita record for pollution-related deaths: 175 per 100,000 people.

The situation is so dire that activists claim pollution in Serbia and other parts of the Balkan peninsula can be seen, smelt, and even tasted, particularly during autumn and winter. This situation makes it imperative for Serbia and its cities to implement solutions to combat air pollution.

The liquid tree is a promising solution that can help to improve air quality in urban areas. It is particularly useful in areas where there is limited space for planting trees.

The use of microalgae in the system is an effective way to bind carbon dioxide and produce oxygen through photosynthesis. This process can significantly reduce greenhouse gas emissions and improve air quality.

Apart from the liquid tree, there are other solutions that Belgrade and other cities in Serbia can implement to combat air pollution.

For example, reducing the use of coal in power plants and transitioning to renewable energy sources can significantly reduce greenhouse gas emissions.

Additionally, promoting public transportation and reducing the number of private cars on the roads can also help to reduce air pollution in cities.

In conclusion, the liquid tree is a promising solution for tackling air pollution in urban areas. With the growing awareness of the importance of environmental protection and the need for sustainable solutions, more cities may consider implementing similar systems to improve air quality.

However, it is also crucial to implement other solutions that can reduce greenhouse gas emissions and improve air quality in the long term. Ultimately, everyone has a role to play in protecting the environment and combating air pollution.
