Smog Eating Sidewalks Are a Real Thing

The eco-makeover of urban surfaces continues. First came white roofs. Then so-called cool pavement. And now smog-eating concrete.

 

Yup, sidewalks with a taste for filthy air.

 

Eindhoven University of Technology scientists have installed air-purifying cement onto a city block in Hengelo, Netherlands, and published the results, which found that it reduced nitrogen oxide air pollution up to 45 percent in ideal weather conditions. This is an average reduction of 19 percent each day.

 

The concrete, dubbed “photocatalytic,” is made with run-of-the-mill cement sprayed with a chemical—titanium oxide—that neutralizes air pollutants, the researchers’ abstract states.

 

“[The concrete] could be a very feasible solution for inner city areas where they have a problem with air pollution,” said researcher Jos Brouwers in 2010 to CNN, when the pavement was in its early stages.

 

So, what’s the world waiting for? Why aren’t urban jungles with smog problems—we’re especially looking at you, Beijing—not jackhammering every piece of old-school pavement and pouring the new stuff?

 

Well, like most public work projects, it all comes down to cost. Titanium dioxide pavement is simply more expensive than your grandfather’s cement.

 

But, with further product tinkering and price–reduction, air-scrubbing pavement could be the stomping ground of the future.

Man, all I can say is if this works then do it. Look at all the money we throw away on virtually nothing and then we are going to not do this one. Okay stupid where did you grow up at because I like to think that I am smarter than that one. Reply

Now if the so called governments and that is all over the world want to invest in our eco system, here you go, do it. This will help more than most anything else they can do so get off your duffs and do something. Reply
