Billboard is First of Its Kind

An engineering school in Peru, UTEC, is expanding and the fact that the construction of the new campus harms the environment is not lost on them.  Students there came up with a billboard that filters the air…a first of its kind.  The billboard is said to do the work of about 1,200 trees.  While this billboard is the first air-purifying billboard, it’s not the school’s first environmentally friendly one.  Last year, the school designed a billboard that turned humidity into purified drinking water.  For more details on this story, click here.
