Zusammenfassung vom Kontext und den Gesamtzielen des Projekts

The CHemPGM project is a multidisciplinary initiative designed to investigate the chemistry and utilization of Platinum Group Metals (PGMs) through international and intersectoral collaboration. Recognizing the critical importance of PGMs for sustainable and advanced technologies, the project brings together universities, research organizations, and small to medium-sized enterprises (SMEs) to form a comprehensive value chain approach. The CHemPGM project addresses critical challenges in the exploitation and utilization of Platinum Group Metals (PGMs)—platinum, palladium, rhodium, ruthenium, iridium, and osmium. These metals are essential for industries such as catalysis, emission control, and green technology. However, they face several challenges like:
- Low recycling rates and inefficient recovery technologies.
- Dependence on limited suppliers (South Africa, Russia).
- Environmentally taxing extraction processes and waste generation.
- Complexities in processing low-grade ores and diverse secondary sources like spent catalysts.

CHemPGM addresses these issues by:
- Advancing understanding of PGM chemistry and recovery processes.
- Developing sustainable recycling methods for high-value applications.
- Promoting industrial symbiosis and circular economy practices.
- Supporting international goals like the European Green Deal and SDGs.

PGMs are crucial for sustainable technologies, supporting Europe's clean energy transition and climate goals. CHemPGM fosters a circular economy, reduces environmental impact, and strengthens supply chain resilience, enhancing EU economic stability and competitiveness.

The CHemPGM project aims to:
- Optimize PGM extraction, separation, and recovery processes.
- Develop sustainable technologies for applications like nanomaterials, catalytic converters, and CO2 capture.
- Align policy-making and standards with circular economy principles.
- Strengthen the EU’s PGM supply chain security.
- Bridge the gap between theoretical research and industrial applications.

Methodology:
- Characterization and Leaching: Uses advanced techniques to extract PGMs from spent autocatalysts and residues, maximizing recovery with minimal environmental impact.
- Separation and Recovery: Employs solvent extraction, ion exchange, and precipitation to recover PGMs in high purity and tailored forms.
- Application Development: Incorporates recovered PGMs into nanomaterials, catalytic devices, and CO2 capture systems to explore industrial applications.
- Evaluation and Standardization: Assesses environmental, economic, and social impacts using Life Cycle Assessment (LCA) to inform regulatory frameworks and align with sustainability goals.
