US mandating Urea scrubbers on diesel vehicles starting 2010
Most diesel vehicles, particularly trucks, manufactured after Jan 1, 2010 in the US will need to have a urea scrubber built in that will ‘scrub’ the nitrogen oxide (NOx) from the exhaust.
The urea-based scrubber will reduce the NOx emissions by as much as 90%, and that in turn can be reduced to near zero levels when used with another filter.
Europe is already ahead of us in this game with already about 500,000 trucks having this technology.
Of course, there is already pushback from trucking companies in particular, but let’s face it – there is going to be some pain as we migrate industries and products to more environmentally-friendly systems.
