Installing catalytic converters into you Car/bus/Truck is costly and only stops CO (Carbon Monoxide?)

It doesn't do anything to stop the CO2 and micron sized carbon particles that behave like micro sized pizza's of toxigens (mix of very toxic chemicals.

Exhaust Emissions from cars can be quickly pumped onto an apparatus that liquefies everything at -175 Degrees Celsius and recycles the heat into mechanical energy

Proper compliance with the Kyoto agreement would have all factory emissions liquefied and transported to chemical treatment factories that could use them in the manufacture of plastics and textiles.

All Industrial factory complexes being built should be designed with additional technology to have all gas/smog emissions pumped underground into an analogue of the sewerage system that would pipe the gasses to chemical treatment & liquification factories that would chemically convert the smog into usable industrial chemicals.

The underground network of pipes would be run by the government and would ban all Industrial chimneys with the given/mandatory requirement that all smog emissions be pumped to the chemical treatment & liquification factories.

momentito,
I'm not trying to beat up on you, just replying with some thoughts.

The factory probably only pays about $50.00 for a converter.
They don't stop CO only reduce it a bit. Then there are NoX, Co2 and one other gas that I can't remember.
The converter does a fair job of reducing these 4 gasses. 2 are reduced if the air fuel ratio is leaner than 14.7 : 1 and the other 2 if richer than the 14.7 : 1 ratio. The car's computer averages this out. All with no moving parts. not bad.
However with a liquefaction system on the car 2 questions come to mind. 1: how much more than a converter would this cost? and 2: what would happen to this system when there is a crash?

Hell the gov. can't even run the driver's licensing office. Now this may not be a bad idea, but if there is a buck in it some corp. would run it. All tho I think that the pollution from a company should be sequestered at the site. we already have to many pipes and wires underground.
