Trees of the future: microalgae reactors to purify the air in large cities 600 384 Climatetrade
  • A 4-meter-high device with intelligent carbon sinks arrives in Spain, capable of cleaning the air that 2,790 people breathe every day, which represents more than 40 tons of CO2 per year. Work is already underway on a new prototype that will also clean viruses and bacteria.
  • This artificial tree is designed to be placed in spaces in the center of large cities that have medium-high levels of pollution such as small parks, schools and hospitals.
  • Climatetrade is responsible for the ‘Biourban’ technology landing in Europe and starting to be marketed in Spain.

‘Biourban’ is a pioneering technology in the world that reduces the carbon footprint and mitigates global warming.The device contains, within its structure, microalgae reactors that absorb pollutant particles to feed on them and, after a natural process of photosynthesis, convert them into oxygen and biomass. Just one of these artificial trees cleans between 40 and 60 tons of CO2 per year.

The system is designed to be placed in the most polluted areas in the center of large cities such as small public parks, schools and medical centers. “The most polluting areas of large cities, structurally do not allow to hold a large number of trees in their spaces, and thanks to this new technology, CO2 capture is maximized and air quality is improved. And, clearly, the installation of a ‘Biourban’ device is complementary to the development of other initiatives such as urban forests, ”says Francisco Benedito, CEO of the Spanish company ClimateTrade.

The first of these artifacts has been successfully installed in Mexico. Specifically, in the capital of the Mexican state of Puebla. There, ‘Biourban’ has reduced pollution levels in one of the busiest areas of the city near the university.

After testing and demonstrating its effectiveness, the ‘Biourban’ technology has landed in Europe from the national company ClimateTrade, which will be responsible for distributing it in Spain. “Cities like Madrid, Barcelona or Valencia suffer from high levels of pollution. With this initiative we intend to maximize the capture of CO2 and improve the quality of the air in our cities.

This technology represents an environmental solution based on nature that will allow the creation of a new circular bioeconomy capable of producing fuels from the pollution generated by our daily activities.
