Trees are the best air purifiers in nature by far, and we already know that our best shot at beating climate change is by planting many more of them. The problem is they take too long to mature. But what if we could instead supplement them with artificial trees until then? Mexican startup BiomiTech believes it may have a way. In fact, they might have a solution that’s even better than nature’s. They’ve developed an artificial device they claim is capable of scrubbing as much pollution from the air as 368 trees. BioUrban, as the device is called, is 14 feet tall and is currently in its second working version. But though it has a metal skeleton that more closely resembles a lamppost, the real magic happens thanks to the microalgae the device houses in its “basket”. “What this system does, through technology, is inhale air pollution and use biology to carry out the natural process (of photosynthesis), just like a tree,” BiomiTech founding partner Jaime Ferrer told TechXplore. Each tree weighs about a tonne, can capture up to 99.7 percent of PM2.5 and 10 particulate matter from the air, and is estimated to clean at least as much as one hectare of forest cover would.  Effectively that’s a single device cleaning up the air for 2,890 people everyday. The BioUrban is also equipped with solar panels to be energy self-sufficient, has built-in air sensors, and requires low maintenance. So not only are they more effective and quicker to set up than actual trees, they also as such require much less space for carbon purification farms. So far, BiomiTech has installed three of these artificial trees. One is in the startup’s home city of Puebla in Mexico, the other is in Colombia, and the third in Panama. They are also in the process of setting up “trees” in other parts of the country They’re not cheap unfortunately, with each BioUrban 2.0 costing about $50,000. But then again, how much more can we save on medical bills we don’t have to spend on anymore?
