I've always wondered how a better filter could be for factory emissions, specifically, if you could pipe the emissions to come out of the bottom of a giant pond, filled with water that will capture a lot of the particulate as it aerates up through the water? and then treat the water the same way you would normally Like if the bottom of the pond was filled with layers of activated charcoal, aerogel pellets (aerogel is known to collect heavy metals pretty efficiently... and then sand. A reverse water filter basically.
