Life cycle assessment

Second IPA LCA Study (2017 data)

In 2020, the PGM industry conducted a second industry-wide Life Cycle Assessment (LCA) based on 2017 production data and adapting to new reporting requirements. The study was reviewed according to ISO 14040 (2006) & 14044 (2006) and ISO/TS 14071 (2014) by an independent technical expert. The LCA has been conducted on primary and secondary (recycling) production of platinum, palladium, and rhodium, since these are the most relevant metals used in catalytic converters.

In 2022, we have updated our data set with new upstream data (energy etc.) from the GaBi database, reflecting changes in the electricity grid and other areas. There have also been some modifications to the secondary (recycling) data as more pre-processing data could be included and a more realistic approach to waste stream calculations has been adopted.

New: LCA data on Iridium and Ruthenium

The IPA membership has undertaken a first industry wide life-cycle assessment of primary produced iridium and ruthenium, based on the data submitted during the second LCA (2017). Reliable data on iridium appear of particular relevance to us given the rapid development towards a hydrogen economy in the EU, and the upscaling of hydrogen projects based on large-scale water electrolysis. 

For access to iridium and ruthenium data please use our LCA Data Questionnaire or get in touch with Tania Bossi at tania.bossi(at)ipa-news.com.

Updated results for primary production of 5 PGMs with 2022 upstream data are shared in the table below:
