Concrete pavers help remove NOx from roadway air

Concrete pavers in the Netherlands are keeping the air cleaner

 

Concrete pavers used to pave a stretch of road in the Netherlands have produced some stunning results.    

Scientists were testing the material in these pavers for their air-purifying capabilities. For this project, 1,000 meters of a road in the municipality of Hengelo was surfaced with these stones. Another area of equal length was paved with traditional paving material for comparison.    

Researchers at Eindhoven University of Technology in the Netherlands (TUe) did three air-purity measurements last spring and discovered that over the  area paved with air-purifying concrete, the NOx content was 25 to 45 percent lower than that over the area paved with normal concrete.  

Car pollution is a big contributor to greenhouse gas emissions
