SEMINAR - Designing Resource- and Eco-Effective Materials, Systems, and Processes, by Elsa Olivetti Ph.D, Research Scientist, Materials Systems Laboratory, Massachusetts Institute of Technology, Cambridge, Massachusetts
Education - Colloquium - WPI Only
Tuesday, April 9, 2013
2:00 PM-3:00 PM
Global demand for materials is immense and rapidly growing; extraction and processing of materials accounts for more than one-third of global carbon flows for human-related activities, on the order of 5.5 Gigatons/year. Direct materials production represents approximately 7% of total US energy consumption. Significant energy savings can be enabled through materials research that addresses design, manufacturing, and recycling processes. In terms of recycling, for bulk industrial and municipal solid waste, improved operations that increase the recovery of material by 25% could offer energy savings upwards of 1 Exajoules. This talk will describe the development of analytical and computational tools that consider the economic and environmental impacts of design, systems, and process choices relevant to materials use. As an example, Dr. Olivetti’s research has shown that development of property-aware, stochastic production planning approaches can mitigate compositional accumulation in materials flows and to inform materials design towards recycling amenable materials, leading to reduced cost and improved environmental performance. This talk will describe several approaches for addressing materials impact through discussion of cases from aluminum production, industrial byproduct reuse, and battery recycling.
