The growing increase in the use of cars and transportation in general is causing an increase the emission of pollutants into the atmosphere. The current European Union regulations impose the minimization of pollution through the use of automotive catalytic converters on all member countries, which stops toxic compounds from being emitted into the atmosphere thanks to their contents of platinum group metals (PGMs). However, the growing demand for cars and the simultaneous demand for catalytic converters is contributing to the depletion of the primary sources of PGMs. This is why there is now increasing interest in recycling PGMs from catalytic converters through constantly developing technologies. There are newer and more sustainable solutions for the recovery of PGMs from catalytic converters, making the process part of a circular economy (CE) model. The purpose of this article is to present two innovative methods of PGM recovery in the framework of ongoing research and development projects.
The article was written as part of the ongoing project “Development of an innovative fully automated and mobile catalyst recycling technology” performed in accordance with the grant agreement no. POIR.01.01.01-00-0648/19-00 concluded under Sub-Action 1.1.1: Industrial research and development work conducted by enterprises under the Operational Programme Intelligent Development 2014–2020 and the PHEIDIAS project: An Innovative Hydrometallurgical Recycling System for PGMs Recovery, number 20220, funded by EIT Raw Materials.
Innowacyjne technologie odzysku metali grupy platynowców z katalizatorów – studium przypadku wybranych projektów
odzysk PGMs, recykling, katalizatory, innowacyjne technologie, gospodarka o obiegu zamkniętym
Rosnący wzrost wykorzystania samochodów i generalnie środków transportu przyczynia się do emisji zanieczyszczeń do atmosfery. Obecne przepisy UE narzucają na wszystkie kraje członkowskie minimalizacje zanieczyszczeń poprzez stosowanie katalizatorów samochodowych, które dzięki zawartości metali z grupy platynowców (PGM) zatrzymują toksyczne związki przed emisji do atmosfery. Jednak rosnący popyt na samochody i jednoczesny popyt na katalizatory przyczynia się do zubożania pierwotnych źródeł pozyskiwania PGM. Dlatego też obecnie coraz więcej mówi się o recyklingu PGM z katalizatorów poprzez ciągle rozwijające się technologie. Powstają coraz nowsze, bardziej zrównoważone rozwiązania odzysku PGM z katalizatorów, dzięki czemu proces ten wpisuje się w model gospodarki o obiegu zamkniętym (CE). Celem artykułu jest przedstawienie dwóch innowacyjnych metod odzysku PGM w ramach prowadzonych obecnie projektów badawczo-rozwojowych.
