  1. IndEcol Expert Meeting “Critical Materials for a Clean Energy Future” Boston, 3 December, 2010 What can Material Flow Analysis (MFA) contribute to the critical minerals discussion? Daniel B. Müller

  2. Motivation Risk for supply chain disruptions and impacts are poorly understood. Difficulty to identify most effective interventions for specific elements(e.g., trade policy, substitution, recycling/reuse) Problem shifts are possible / likely, but poorly understood Hypothesis System approach based on MFA can support the evaluation ofcritical materials policies  systems defined in space and time (not functional units)

  3. Research opportunities for MFA • Characterize critical elements cycles- links between cycles of different materials- links between material cycles and energy and emissions- links between cycles of different countries (trade) • Analyze dynamics of cycles- drivers (lifestyle, penetration of new technologies, trade…)- roles of stocks- sensitivities • Develop scenarios- anticipate demand- anticipate supply (limits)- identify problem shifts (to other materials, energy, emissions)- test impacts of supply disruptions- evaluate strategies (e.g., interventions in different places of chain)- risk assessment •  Data challenge!

  12. Example by-product element: indium (demand) • Uses of indium • Thin films:transparent and conductive coatings of indium tin oxide (ITO) for - liquid crystal displays (50% of In use!)- flat panel displays- touch screens- photovoltaic cells • smart windows • …  Demand is rising sharply Recycling challenge: Very small quantities per unit, but many units

  13. PGM Metal families – most precious & special metals are coupled to major metals production •  supply of many “technology metals” is price-inelastic: • Increased demand can only be met by primary production if demand for major metal rises accordingly • Short term demand surges lead to price peaks (see Ir, Ru, In) • Effective recycling important for supply security Source: Ch.

But with few substitutes.

  18. Data challenge • Data availability for critical materials is critical! • Data provided by governments are usually not integrated into a systems context.  limited potential to inform policies and own measurement programs •  a growing number of universities spend a lot of time compiling data, with different degrees of transparency – waste of brain power and money small incentives for data sharing… •  Coordinated effort needed! UN Statistics: harmonized… Manuf Use EOLM Prod Geological Surveys National accounts Lithosp Landfills, other repositories
