Leading the Way in HDD Catalysts

The market for catalysts to control harmful emissions from heavy duty diesel (HDD) vehicles, such as trucks and buses, is growing rapidly driven by tightening legislation for both on road and non-road applications around the world.

Johnson Matthey has developed world leading catalyst technology for HDD applications and, as a result, has established a very strong market position thanks to sustained investment in R&D and state of the art manufacturing facilities, including at our plant in Smithfield, USA (pictured). 2011/12 marked another strong year for Johnson Matthey’s HDD catalyst business where sales grew by 48% to £438 million and operating profit more than doubled.

New and tighter legislation will impose increasing technical demands on the emission control catalyst systems required for HDD applications and technologies must cope with controlling oxides of nitrogen and particulate matter to extremely low levels. This inevitably results in increasing value for Johnson Matthey. Furthermore, as legislation extends to cover more vehicles and additional regions of the world, the group’s commitment to maintaining technology leadership in this field positions us well to benefit from future growth in demand.
