Smog-Eating Concrete Developed in Netherlands

Smog Eating Concrete

Dutch scientists have completed an analysis of their new smog-eating concrete. The special pavement can reduce nitrogen oxide air pollution by 45%, that translates as an average reduction of 19% percent over a day. The special concrete pavement is sprayed with titanium oxide (TiO2) able to convert air pollutants and convert them into less-dangerous chemicals, such as nitrates. The titanium dioxide pavement is more expensive than average cement; however, the cumulative benefits will be much higher than the ones received when using traditional pavement. Initial tests have demonstrated that the pavement could cost about 50% more than regular pavement although it only adds 10% more of what will cost the repaving of the road. The new pavement is expected to be tested during the next months in places such as Los Angeles, and other highly congested areas.
