Anti-Pollution Innovation

This is an. . . interesting way of dealing with pollution. But it leaves me with a couple of questions.

Does this create a different smell? Because that could be worse than the bus pollution. Or almost.

Could this be a possible solution to the "trucker bombs"? You know, just set up deposit boxes or bins at rest stops for truckers to contribute and refill tanks on their trucks with the refined liquid (which could also be provided at other locations).
