Mangia, mangia!
At the La Biennale di Venezia exhibition, some Italian scientists have unveiled a special cement that can be painted on buildings or roads that actually reduces pollution and thus also protects structures, such as ancient monuments, from damage-causing smog. They call it cemento mangiasmog (pronounced chaymEnto mAnja-smog), or smog-eating cement. In tests they've conducted, it has reduced pollutants in the air associated with auto emissions and factories by 45%-60%. Check out the story here in English.

I'm sorry, but does cement eat? If so, does it--like everything else that eats, from jellyfish to Republicans, also excrete waste? If so, what does smog-eating cement excrete? If it's gasoline, then I think we're in some kind of Kurt Vonnegut punk'd episode.
Well if the metaphor of eating is just a tad too metaphorical or poetical for you, the actual process is called photocatalysis. The "excrements" from this process are water, nitrates and carbon dioxide, which, to quote Rossano Amadelli, "...aren't neccessarily 'clean', but from an environmental standpoint they're much more tolerable."
