Platinum group metals (PGMs) are used rather than consumed - their high recyclability means they can be re-used many times, reducing their impact on the environment.
PGMs are the six-member family of elements which include platinum, palladium, rhodium, ruthenium, iridium and osmium. PGMs are an excellent raw material, catalyst and manufacturing ingredient due to their unique chemical and physical properties.
PGMs form the often-invisible heart of many everyday items in modern society. They are used in the manufacture of hard disks, mobile phones and aircraft turbines, in anti-cancer drugs and dental implants, in industrial catalysts and ceramic glazes, and in many more products.
Platinum gauzes play a critical role in nitrous oxide (N2O) abatement programmes, significantly reducing global greenhouse gas emissions. They are also pivotal in air and water purification systems, breaking down harmful pollutants. Innovative secondary PGM-bearing catalysts can reduce up to 90% of the N2O emissions generated during fertiliser production.
Implats promotes and advances technologies related to the hydrogen economy and fuel cell innovations, positioning itself at the forefront of sustainable solutions powered by PGMs. This supports the global shift towards decarbonisation and emissions reduction.
Through Implats’ investments in AP Ventures, it develops markets for key PGM applications such as in hydrogen, fuel cell mobility and energy storage. The Group pioneers research and development in fuel cells, promising advancements in combined heat and power applications, distributed power generation and portable energy solutions.
By far the largest use of PGMs today is in automobile catalytic converters (autocatalysts), which are pollution-control devices fitted to cars, trucks, motorcycles, and other mobile machinery. Catalytic converters reduce outdoor air pollution in cities and rural areas.
PGMs are the active ingredient in many pharmaceuticals and a vital element in modern surgical technologies and medical componentry. Platinum has become the favoured metal in many medical applications because it is biocompatible and durable, with excellent electrical conductivity and radiopacity.
Platinum is rare and pure, with a natural white colour. The modern history of platinum only begins in the 18th century, but archaeologists have found objects dating from as far back as 1200 BC, decorated with gold-platinum hieroglyphics. Today, platinum is the pre-eminent metal for bridal jewellery in many countries and promotional campaigns are focused on developing the market for self-purchase and fashion jewellery in Asia in particular.
