DEF
Reduces emissions from diesel engines in cars, trucks, farming equipment and other heavy machinery
Diesel exhaust fluid (DEF), which is also known as AdBlue in Europe and marketed as AdGreen by Fertiglobe, is a non-hazardous aqueous urea solution consisting of approximately 67.5% deionized water and approximately 32.5% urea.

DEF is used in Selective Catalytic Reduction (SCR) systems to lower harmful vehicle exhaust emissions from diesel engines, with the added advantage of improving vehicle fuel economy by approximately 5% and using diesel fuel more efficiently.
DEF breaks down nitrogen oxides emissions into nitrogen gas and water vapor, thereby eliminating environmentally harmful emissions from cars, trucks, buses and other heavy-duty vehicles.

Regulations in the United States, Europe and China require replacing older vehicles, particularly heavy- duty trucks, coupled with higher dosing rates in newer generation diesel engines.
DEF provides a transitional option for emissions abatement for truck and rail in the near-to-medium-term, as the switch to electric vehicles has proven to be challenging for heavy-duty trucks or farm vehicles. This is due to poor power-to-weight ratios, leaving few near-term alternatives to DEF for emissions abatement in truck and rail.
