Air quality is a pressing concern for major cities, which are striving to balance technology with ecology. This is where “liquid trees” come in – a innovative solution that’s already being implemented in cities like Belgrade. These devices use microalgae and advanced technology to capture CO₂ and release oxygen, mimicking the process of photosynthesis.
What are liquid trees?
The concept of liquid trees is quite remarkable. They’re compact, functional devices that don’t require large spaces to operate. In fact, a single liquid tree can emulate the carbon capture ability of about 200 trees. This makes them perfect for urban areas where space is limited. They’re estimated to be equivalent to purifying an area of 200 square meters of grass, which can have a significant impact on areas with limited green spaces.
These small surfaces can double the effectiveness of traditional trees, with some even increasing it by 10 to 50 times. This technology has the potential to revolutionize sustainability in cities. The fact that they can provide clean air in densely populated areas is a game-changer. It’s not just about making a difference; it’s about inspiring others to follow suit.
Liquid trees in Belgrade: Urban innovation
So, how do these liquid trees work? In Belgrade, they’ve been installed in public squares and parks, and they’re not only purifying the air but also equipped with solar panels and a night lighting system. One of the advantages of liquid trees is that they’re low-maintenance. They only require the extraction of biomass generated by algae and the replacement of water and nutrients every now and then. The extracted biomass can even be reused as fertilizer, adding an extra layer of ecological value to the system.
The impact of liquid trees on the urban landscape
While liquid trees aren’t the only solution to air pollution, their ease of implementation and efficiency make them an attractive option for cities worldwide. Tests are being conducted to further develop this technology, demonstrating the global interest in finding innovative solutions to the environmental crisis. This is part of the “New Urban Forestry” movement, which seeks to transform the concept of vegetation and adapt it to the needs of modern cities. Each liquid tree can purify an area equivalent to 200 square meters of grass, a significant surface area considering the lack of green spaces in cities. This highlights the importance of liquid trees as a solution that can change the way we breathe in urban areas.
