Your issues and needs
Mineral raw materials (building materials, agricultural fertilisers, base metals and technology metals for transport, digital technologies or electricity generation, etc.) are needed directly or indirectly for all human activities. Whether they come from underground mining or recycling, these mineral materials have environmental impacts throughout their lifecycle, from water and energy consumption, discharges into water, air and soil, and land use.
Faced with the environmental and social issues of our time, society has growing expectations of companies and organisations. At a time when the global economy is multiplying the number of players involved in product and service value chains, ensuring "sustainable and responsible procurement" requires a detailed knowledge of processes and sectors, as well as of their effects on the environment.
Our added value
BRGM researchers analysed the flows of mineral materials in the economy and their impact on the environment, as part of R&D studies focusing on:
- The environmental performance of ecotechnologies for metal production (primary or secondary);
- The mineral resources economy: quantification and criticality of the raw materials needed for developing new industry sectors (energy transition, construction, electromobility, etc.), risk assessment;
- The mapping of material flows between countries and between industry sectors, and their consequences on the environment (carbon, water, resources, etc.);
- Development of lifecycle analysis methodologies: resource wastage indicators, long-term impacts of mine spoil, etc.
Our proficiency with multi-regional input-output tools (MRIO) and process modelling, coupled with BRGM's expertise in the lifecycle of mineral materials, enabled us to shed light on the environmental issues relating to the procurement of raw materials for an activity. We applied a systemic approach from the process through to the global economy, and were able to trace extraction and emission sites all along the product value chain and identify pollution transfers.
