On: Tower purifies a million cubic feet of air per hour

[benihana]

So what happens to the particulates after they're collected? Is this a matter of "let's take these molecules and use them somewhere", or is it like we have a shit-ton of solid waste full of sulfur and hydrogen and we have to bury it?

[akiselev → benihana]

We're talking about air pollutants which are mostly industrial waste and exhaust so they're practically useless and have to be stored.

Since this pollution is already in our air regardless, it doesn't really matter how we store it as long as it's not in our lungs.
