Liquid3 (also known as Liquid Trees) is a clean energy photobioreactor project whose purpose is to replace the function of trees in heavily polluted urban areas where planting and growing real vegatation is not viable.
The project was designed by the Institute for Multidisciplinary Research at the University of Belgrade and was awarded as one of the 11 best innovative and climate-smart solutions within the Climate Smart Urban Development program developed by the UNDP and the Ministry of Environmental Protection.[1]

Overview[edit]
The Liquid3 algial photobioreactor is powered entirely by solar panels. The glass tank is embedded into a structure that acts as a bench and is outfitted with other utilities such as charging ports. Similar to other photobioreactors, air is sucked through a pressure pump and fed to the microalgae, with oxygen being released as a byproduct. Additionally, the Liquid 3 bioreactor is also able to filter out heavy metal contaminants in the air, and contains a temperature regulation system in case external climate conditions were to become too extreme for the microalgae.[2][3][4] The creator of the Liquid 3, Dr. Ivan Spasojevic, was motivated to install it in Belgrade due to the city's struggle with pollution.[5]
Criticism[edit]
Trees have many benefits that photobioreactor infrastructure like Liquid3 do not provide, such as lowering air temperature, reducing wind speeds, and create wildlife and plant diversity.[6] However, Liquid3 has stated the purpose of the photobioreactor is "not to replace forests but to use this system to fill those urban pockets where there is no space for planting trees."[7]
