Liquid 3: A Game-changing Innovation

purpose and improve the quality of life. However, Ivan Spasojević, one of the project's developers, believes in the potential of the idea and plans to expand the use of microalgae in Serbia.

This innovation can function like three trees combined. Plus, it takes lesser space compared to a real tree. In a report by Envirotech, the microalgae of the Liquid 3 can effectively lock carbon dioxide emissions 10-15 times higher than regular trees.

Liquid 3 is a unique instrument in Belgrade's fight against dirty air. It is the country's first urban photo-bioreactor, a solution for reducing greenhouse gas emissions and improving air quality. It holds 600 liters of water and employs microalgae to bind carbon dioxide and produces pure oxygen via photosynthesis –like a real tree, but even better. And, such innovation holds great potential in the Philippines, particularly in solving air pollution.

The Institute for Multidisciplinary Research at the University of Belgrade created Liquid 3, a cuttingedge urban photobioreactor. This innovative design effectively removes carbon dioxide while generating oxygen, and biomass, offering a different long-term strategy for greening urban landscapes with constrained space and high pollution.

Liquid 3 is Serbia's first urban photobioreactor, and it's situated in the heavily polluted metropolis of Belgrade. It can bind carbon dioxide and use photosynthesis to create pure oxygen, which makes it a potential solution to the city's air pollution problem.

The institute made use of single-celled freshwater algae that can withstand extremes in temperature and grows naturally in Serbian ponds and lakes. Currently, the prototype requires about 60 euros per month in maintenance.

Liquid 3 is not a replacement for city trees as they serve a crucial social

Now, such innovation as the "liquid tree," presents an opportunity for the Philippines to address one of its most pressing environmental issues: air pollution. The country has been struggling with this problem for many years, with pollution levels exceeding the acceptable limit set by the Department of Environment and Natural Resources (DENR). The situation has become dire, and the effects of air pollution on the ecosystem and the health of the people have been alarming.

The Liquid 3 project could be a game-changer for the country. By employing this technology, we could potentially reduce the number of pollutants released into the air, ultimately contributing to cleaner air and a healthier environment for Filipinos. Moreover, it has the potential to significantly reduce greenhouse gas emissions, which contribute to climate change. By doing so, this project could help the Philippines to address the effects of climate change that are already being felt across the country, including more frequent and intense typhoons, sea-level rise, and crop damage. The benefits of the Liquid 3 project extend beyond just improving the environment and mitigating climate change. The use of microalgae in the project also has the potential to generate biomass and biofuel, create compost for green areas, and treat wastewater. These uses could provide additional benefits for the country, such as reducing waste and generating renewable energy.

If Philippines can fund such project like this, surely we can have fresher air in cities across the country.
