OK, so I see a solution to one problem that creates another one, a little bit like all these electric cars with their lithium batteries. When you have millions of sponges full of toxic crap, where are you going to get rid of them?

The sponges are rinsed to be used again and the metals are recovered for use in batteries.

OK, I may be wrong, but surely even rinsing them means there are certain toxic chemicals aside from those used to make batteries that need to be disposed of?

Good questions and better put to the researchers at Northwestern University. We appreciate your thoughtful feedback! https://news.northwestern.edu/stories/2023/05/metal-filtering-sponge-removes-lead-from-water/?fj=1#a...

Not trying to pick a good idea or a part but just trying to understand where everything goes in the end. Electric cars are great until we have to recycle all these lithium batteries, just makes me wonder why we didn’t go straight for the hydrogen powered vehicle.
