Air and Climate
Globally (various continents)
A British company with global operations, Johnson Matthey is a world leader in the development and supply of catalytic systems for air pollution control. Catalyst technology from Johnson Matthey helps to control exhaust emissions from mobile and stationary sources of air pollution, including passenger cars and motorcycles, trucks and buses, constructions equipment, as well as power plant and other industrial processes. The technology is sold either direct to vehicle and equipment manufacturers, or on to ends users via dedicated sales agents or distributors selected on the basis of their engineering capabilities and specialist knowledge of user needs.
Johnson Matthey’s manufacturing sites (see below) around the world are dedicated to producing world-leading products for controlling emissions from mobile and stationary sources.
Our state-of-the-art manufacturing process, Precision Coating, applies measured doses of platinum group metals to the tightest tolerances achieved in the industry.
Combined with our advanced catalyst formulations, Precision Coating enables us to provide zoned catalysts, with two or more formulations applied to the same substrate. These products can achieve desired emissions reductions by targeting the most appropriate precious metal to its optimum position on the catalyst. This offers the opportunity to reduce total precious metal usage, as well as permitting greater flexibility in system design.
Johnson Matthey’s Technology Centres (see below) around the world are dedicated to creating world-leading products for controlling emissions from mobile and stationary sources.
State-of-the-art equipment and analysis, along with unparalleled expertise in catalysis, is used within customer collaborations, generic catalyst development and contract testing operations.
Johnson Matthey is known as a pioneer in the field of emissions control, having made the world’s first autocatalysts in its Royston facility, and invented the innovative CRT® diesel particulate filter technology.
Our innovation has been recognised in the awards we have received over the years:
- 1976 - Queen’s Award for Technology (3-way autocatalyst)
- 1980 - Royal Academy of Engineering, MacRobert Award (3-way catalyst)
- 1995 - Queen’s Award for Export, Environment (autocatalyst)
- 2000 - Royal Academy of Engineering, MacRobert Award (CRT® technology)
- 2009 - Queen's Award for Enterprise: International Trade and Innovation
Johnson Matthey’s research and development activities are focused on improved catalyst performance, along with reductions in platinum group metal content of our products.
Our technology enables cost-effective compliance with regulations.
Our emissions control products help contribute to sustainable development by improving air quality around the world.
Our own environmental policies and procedures are designed to meet or exceed relevant environmental legislation wherever our sites are located. We seek to minimise waste and reduce emissions from our own operations by efficient use of resources and using best available techniques.
It is our policy objective to have all production sites certified to ISO 14000 or 14001.
Recovering your Precious Metal Values
In order to make Precious Metal Catalysts viable, it is important that the PGM (platinum group metal) content is recovered and re-used, not only for their financial cost but for the sake of the environment.
With over 100 years of experience, Johnson Matthey is the largest global full-service refiner of PGMs in the world, representing the world's most comprehensive and advanced sampling and refining facilities available.
The advanced technology employed by Johnson Matthey maximises precious metal recovery and ensures compliance with the most stringent environmental legislation. Johnson Matthey is ISO and NMAS accredited and is proud of the honest approach adopted in all aspects of every refining transaction.
No other company in the world has been as deeply involved in the evolution of innovative precious metal recovery processes. Our investments in upgrading our facilities and creating new technologies are testament to our commitment.
Any filter has a finite capacity. Diesel particulate filters must be cleaned out, intermittently or continuously, if they are not to block. This is most important, since an overfilled filter can damage the engine through excessive exhaust back pressure and can itself be damaged or destroyed.

Small Utility Engines
Johnson Matthey is one of the first companies to provide catalysts for 'green' lawnmowers in Europe and for propane powered floor care equipment in the US. Johnson Matthey provides a complete line of catalysts for both handheld and non-handheld utility engines under 37kW (50hp). Catalyst can be supplied on either ceramic or metal substrates for either rich-burn or lean-burn engines.
