✦ Synopsis

and synthetically produced aqueous urea solution. Trucks and heavy commercial vehicles with SCR technology attain the Euro 4 exhaust gas emission standards prescribed from 2006 and will, in an improved version, also be able to meet the next stage, Euro 5, which comes into effect from 2009. Supplies of AdBlue are now assured by leading European urea producers as: AMI Agrolinz Melamin International GmbH, BASF AG, Fertiberia SA, Grande Paroisse, SKW Stickstoffwerke Piesteritz GmbH, and Yara International ASA which are able to manufacture AdBlue in six European countries. The AdBlue producers will further adapt their capacities to the development of the markets. Two well-known oil companies, OMV and Total, first European Refining and Marketing company, are already developing their strategy for the implementation of SCR technology for commercial vehicles.
