Serbia is among the nations with the very worst air quality on the planet. A novel solution to sequestering GHGs in Belgrade’s most concentrated urban area, is the ‘Liquid 3’.
If humanity has any chance of remaining under a 1.5C temperature rise, atmospheric greenhouse gases must decline by 43% before 2030 and 60% by 2035 – reveals the latest IPCC report.
As well as nationwide transitions away from fossil fuels, carbon removal through natural sequestration and nascent technology has now been described as essential to stay within any theoretical pathways.
Speaking on the latter variety of project, a one-of-a-kind installation is helping to combat urban pollution in Belgrade, Serbia. Dubbed the ‘Liquid 3,’ this mesmerising device essentially operates like a tree.
Passers-by are visibly intrigued by the bioreactor and bubbling green liquid, which uses microalgae to bind carbon dioxide from the air before converting it to pure oxygen through photosynthesis.
Climate experts estimate that such microalgae is some 10 to 50 times more effective at locking away CO2 than regular trees. Impressive, eh?
That’s not to say that its founder Dr. Ivan Spasojevic is keen to uproot natural sequesters in Belgrade in favour of Liquid 3 units every 100 yards. On the contrary, the technology has been developed to fill urban pockets where there is no space for planting trees.
