The photobioreactor is a completely new biotechnological solution for air purification and the production of oxygen. 
In an aquarium of six hundred liters of water, we have algae that bind carbon dioxide and produce pure oxygen through photosynthesis. 
The project is designed to be multifunctional. 

LIQUID3 is also a bench, it has chargers for mobile phones, as well as a solar panel, thanks to which the bench has lighting during the night. 
The municipality of Stari grad has decided to support this project which directly contributes to improving the quality of life of our fellow citizens, public health and cleaner environment through using smart and innovative solutions 

• The microalgae in "LIQUID 3" replace two 10-year-old trees or 200 square meters of lawn. 
  
• The system is the same because both trees and grass perform photosynthesis and bind carbon dioxide. 
  
• The advantage of microalgae is that they are 10 to 50 times more efficient than trees. 
  
• Our goal is not to replace forests, but to use this system to fill those urban pockets where there is no space for planting trees. 
  
• In certain conditions of great pollution, trees cannot survive, while algae do not mind that pollution.
