Shanghai first tried to use road paint to eliminate exhaust gases in the air. Experts said that the Shanghai Municipal Environmental Protection Bureau has painted a photocatalytic coating on the 120 meter long road surface of the Fuxing Road Tunnel, which has been tested to absorb nearly 45% of the toxic waste gas in the air. This latest photocatalysis technology is expected to be popularized in Shanghai

according to experts, although this section of road using "Photocatalyst" technology is visually no different from ordinary roads, the monitoring and comparison of Shanghai Academy of environmental sciences have proved that it can absorb nearly 45% of toxic waste gas in the air in the natural environment. According to theoretical calculations, if such an "ecological road" promotes the speed valve here, for each additional square kilometer of road surface, "32 tons of pollutants can be reduced from the air in Shanghai from the use of safety equipment that often breathes and keeps in good contact with others every year"

officials from the Shanghai Municipal Environmental Protection Bureau said that Shanghai currently has 2.3 million vehicles, which are still increasing. 80% of the urban exhaust gas comes from vehicle exhaust. It is the first time in mainland China to use road coatings to improve air quality and eliminate exhaust gas. Therefore, the relevant departments in Shanghai will further demonstrate and implement the specific pilot scope

according to local media today, the cost of "ecological road" is about 90% higher than that of ordinary pavement. Therefore, affected by factors such as cost and pavement loss, this technology is currently only suitable for use in specific road sections, and the possibility of large-scale popularization remains to be practiced
