Motivated by the critical situation of air pollution in Mexico City, a team of engineers, researchers, and biologists joined forces to create an artificial, robotic tree specifically designed to improve air quality. This exact invention helped BiomiTech win the innovation award at the 2018 Pollution Expo in Birmingham, and is already looking to be a compelling solution for air pollution problems.
The air purifying robotic tree called BioUrban uses a microalgae filtration system to absorb polluted air and produce clean, fresh air. Inspired by the very essence of nature, BioUrban is based on the photosynthesis principle, inhaling pollutant compounds like carbon monoxide and nitrogen oxides, and exhaling pure oxygen.
The BioUrban robotic trees are capable of capturing an annual air capacity of 13,140,000 m3. They filter polluted air with an efficiency of 99.7%, and one artificial tree releases the pure oxygen equivalent of 368 young trees. To put it in a different perspective, BioUrban provides enough clean oxygen for 2,850 people on a daily basis.
Given that densely populated cities are desperately struggling with air pollution, and natural trees take a lot of time to grow, this solution seems like the best shot we have to fight air pollution quickly and efficiently.
Furthermore, the BioUrban trees have zero negative impact, since they don’t produce any waste, and they use algae which already exists in nature.
According to BiomiTech, the goal of BioUrban is not to replace trees, but to complement them and aid them in filtering out our polluted air. The 4 m high metal trees have already been installed in Mexico, Columbia, and Panama, with more cities on the horizon that are also interested in implementing BioUrban.
