The University of Engineering and Technology (UTEC) in Lima creates a billboard to diminish air pollution. The university started to create the billboard to reduce air pollution at a construction site in the Peruvian capital.
The Billboard is really effective: it filters as much air as approximately 1200 trees which is similar to about 3,5 million cubic feet of fresh oxygen per day. The Billboard arrived right on time because the World Health Organization reported recently that Lima has the worst air pollution of all cities in Latin America.
Most of Lima’s pollution, however, is caused by vehicle traffic, especially of old cars. Therefore the importantion of used vehicles is no longer permitted and the city government has successfully removing many of the older public transport vehicles from the roads. But at the same time there has been a dramatic increase in the number of private vehicles, creating heavy traffic congestion all over the city.
The UTEC has attracted attention before when it created another billboard: one that captures the mist of Lima, turning it into potable drinking water. The supply of safe drinking water in Lima, the world’s second biggest desert city, is a big challenge for Peru.
