Dutch scientists say their revolutionary concrete can cut urban air pollution by 45 percent

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.

A roof covered with solar reflective white paint reflects up to 90 percent of sunlight as opposed to the 20 percent reflected by a traditional black roof.
