The smaller the PM gets the worse it is healthwise. Unfortunately manufacturers meet more stringent PM standards by crushing the particles smaller.
If they were serious about cleaning the air and fighting climate change they'd have started next gen nuclear programs twenty five years ago.
- zardo 4y agoYou can't meet the the standards by crushing particles, it's a mass limit inclusive of all particles of the regulated size and smaller.
- feoren 4y agoYeah I'm really not sure where you're getting this from. You can't really "crush" particles to smaller than 2.5 microns, and to do so, you'd have to somehow extract it from the emissions stream. If you can extract it from the emissions stream, why would you crush it? Just ... don't re-emit it. Manufacturers meet stringent PM standards mostly by filtering or by adding moisture, and sometimes by modifying the combustion that happens. Reducing your particle size wouldn't even help: The limit is on PM <2.5 microns. If anything, you'd be much better off somehow agglomerating your particles to be larger, which is one of the reasons adding moisture helps.
