Electrochemical Recycling of Platinum Group Metals from Spent Catalytic Converters
Metals, 2020 Platinum group metals (PGMs: Pt, Pd, and Rh) are used extensively by the industry, while the natural resources are limited. The PGM concentration in spent catalytic converters is 100 times larger than in natural occurring ores.

Forensic Studies on Spent Catalytic Converters to Examine the Effect of Diesel and B100 Pongamia Biodiesel on Emissions [PDF]
Sustainability, 2021 The ever-increasing demand for transport is sustained by fossil fuel-based internal combustion (IC) engines fitted with catalytic converters (CCs) while alternative options and fuels are still emerging. Biodiesel seems to be a potential alternate to diesel, but the formation of NOx and smoke are major issues.

A new approach to recover platinum-group metals from spent catalytic converters via iron matte
Resources, Conservation and Recycling, 2020 Abstract Decreasing stocks of natural resources and continuously increasing demand for platinum-group metals (PGMs) sustain interest in studies on spent catalytic converters. Recycling spent catalytic converters to extract PGMs not only provides raw materials for the precious metals sector, but also provides a sustainable recycling method for further
