The University of Engineering and Technology (UTEC) of Peru is currently in the process of building a new campus. Every construction site comes with a lot of pollution, particularly dust that pollutes the air. To help combat this, UTEC has installed a billboard in the middle of the construction site which actually purifies the air.
The billboard cleans as much air as as 1200 trees, and is able to process 100,000 cubic meters of air each day. The polluted air gets pulled into the billboard, which uses thermodynamic principles to dissolve pollutants, then it releases the fresh air again.
And, it's not just UTEC's construction site that gets to reap the benefits. The effects of the purified air can be experienced for a 5-block radius.
"We seek to demonstrate that engineering is behind it all," Jessica Rúas, Director of Promotion at UTEC, told Gizmag. "And what better way to also show that than through advertising that changes the world, helps the community and cares for the environment."
