  • Title:  Presentation: Life Cycle Assessment and Other Approaches in Evaluating System-Wide Environmental impacts of Products, Processes and Packaging

Presenter Dr. Mary Ann Curran
Date: October 15, 2015 at 3:00pm
Dr. Mary Ann Curran is an internationally-recognized expert in the field of Life Cycle Assessment (LCA). After 32 years of federal service as a research chemical engineer with the US Environmental Protection Agency, Dr. Curran works independently as an LCA and sustainability consultant (BAMAC, Ltd., Cincinnati, Ohio). Upon receiving a bachelor’s degree in Chemical Engineering from the University of Cincinnati in 1980, Dr. Curran began working for the EPA’s National Risk Management Research Laboratory in Cincinnati, Ohio. After working in waste management research for several years, her research turned to industrial pollution prevention. In 1989, this work introduced her to a new environmental management approach called LCA. Through 20+ years of LCA research, networking, and publishing, she developed an in-depth knowledge of the field and created an extensive network of LCA researchers and practitioners world-wide. Dr. Curran is the Editor-in-Chief of the International Journal of Life Cycle Assessment. She has authored and co-authored numerous papers and book chapters which address the LCA concept and its applications, and created the LCA Handbook: A Guide to Environmentally Sustainable Products as editor and co-author (published by Scrivener-Wiley in October 2012). She has presented EPA’s activities in LCA-related research at technical meetings across the US and in Europe, South America, South Africa, Asia, and Australia. Dr. Curran studied Environmental Management and Policy at Lund University, Lund, Sweden (MSc 1996); and earned a Doctor of Philosophy degree in Erasmus University’s International PhD program on “Cleaner Products, Cleaner Production, Industrial Ecology and Sustainability” for her thesis entitled “Development of Life Cycle Methodology: A Focus on Co-Product Allocation” (2008). Dr. Curran is a Fellow of the American Institute of Chemical Engineers (AIChE).

  • Workshop: “Prediction of the migration: beyond conventional estimates”

Presenter: Dr. Olivier Vitrac

Date: July 1, 2015
Abstract: Regulations in the EU and the US authorize the use of migration modeling to demonstrate the compliance of food contact materials or substances. The legal basis assumes that there is enough scientific evidences to support compliance but not for non-compliance. This presentation will give an overview of the different recognized methods to overestimate the migration in food and consumer exposure. In simple cases, the overestimation can originate from conservative assumptions or from probabilistic estimates. For more sophisticated cases involving complex designs or industrial practices along the supply chain, more robust approaches are required. A recent methodology based on Failure Mode and Effects and Criticality Analysis will be illustrated as well as the concepts of food packaging “safe-by-design”.  Please click the following link to know more about Safe Food Pack Design

  • Title: An atomistic Flory-Huggins formulation for the tailored prediction of activity and partition coefficients.

Presenter: Dr. Olivier Vitrac

Date: June 30, 2015

Abstract: Claiming that activity coefficients are the easiest properties to calculate was a utopia until few years ago. Conventional techniques sample configurational space by particle insertion/deletion methods or by thermodynamic integration ones. They are particularly time-consuming and almost intractable for large solutes in entangled polymer matrices. Conversely, we developed new tailored methods to estimate chemical potentials or activity coefficients in situations met in food packaging applications: aqueous dominant mixtures, homopolymers and copolymers. They rely on a compressible Flory-Huggins formulation at atomistic scale with additional entropy and enthalpy corrections inferred by molecular dynamics simulation. Corrections are particularly important to reproduce radial distributions, cooperative hydrogen bonding and the residual elastic energy in glassy polymers. The whole approach has been validated to estimate partition coefficients of various substances (e.g., aroma, plastic additives, homologous series of alkanes and alcohols) between a broad range of polymers and food simulants.

  • Title: Diffusion coefficients of organic solutes in polymers: new perspectives of prediction

Presenter: Dr. Olivier Vitrac     

Date: June 30, 2015
Abstract: Diffusion coefficients in and through polymers are of general interest in many technological applications from material science, membranes to packaging applications. It is had been thought for decades that they could not be predicted from first principles for bulky and flexible solutes. This presentation bridges two theories, the free-volume and the Rouse theory, to reproduce the scaling of diffusion coefficients of solutes with linearly repeated patterns in arbitrary polymers at any temperature. The resulting approach is demonstrated for both aliphatic and aromatic solutes based on molecular simulations and experimental data. Extensions to other branched solutes are sketched.
