Particulate Matter's Sticking Point
![JessicaYoon](https://us.v-cdn.net/6031116/uploads/userpics/216/nZVD4ERZ3LIBV.jpg)
Using glue to trap particulate matter? U.K. Prime Minister Boris Johnson (when he was the Mayor of London) thought it was a good idea. As an expert, what are your thoughts on the possibilities for this to be effective? Please share with us interesting, novel, and innovative ideas meant to tackle particulate matter at a larger scale (city/state/nation) that have been successful and/or unsuccessful - and why?

Given your area of expertise and experience, I feel you should be able to answer Jessica's question. @JessicaYoon
Please join the discussion.
@jamesburbridge do let us have your input on the above comments.
Given how much went into building and operating it, I am not sure there are net savings in pollution. @jamesburbridge
Please share your thoughts on James question and Jessica's solution. Thanks.
It's much better to tackle emissions at source (the exhaust pipe/chimney). Once pollutants are in the air they are not only being hovered up by a (hopeful/hypothetical) technology, but by the lungs of people. In the case of vehicle emissions people are usually on the front line, right next to the road - breathing pollutants in before any ambient technology has had chance to remove them from the air.
The idea at the top of this page has limited effectiveness. The article says: The city’s studies showed it reduced PM-10 (that’s particulate matter with a diameter of 10 micrometers or smaller) by 10 to 14 percent.
I have a patented solution to deal with indoor pollution. I designed a drone based device, measures 8"x 4" ( 20cm x 10cm ) small autopilot drone. Under the drone there is a system of TIo2 charged plates and with UV irritated tube and Ions generator and O3 generator. User can command the drone remotely ( using Wi-Fi ) and watch its action live when he is away from home. The drone takes off and shower the rooms with billions of negative Ions which attach to polluted air particulates make them heavier. Polluted air participated to ground due to extra ions. UV activates TIo2 then converts bad air and bacteria to harmless Co2 and water. And O3 eliminates bad odors. By the time user returns home, the rooms become free from polluted air. Also, the drone equipped with a set of high voltage screens that kills mosquitoes in contact. 10-2-19
Thank you for sharing it with us.
We have developed a new porous material (SUNSPACE), that can trap air particulate matter. It can trap also ultra-fine PM. It can be applied as a coating on external building surfaces, such as walls, roofs, and so on....

Thank you very much. For gaseous pollutants it is possible to add TiO2 (anatase) to the material. In this manner it would be possible to degradate some gaseous pollutants, such as nitrogen oxides.
