Management of the End-of-Life of Aircraft at Bombardier AerospaceJulien Dezombre, Bombardier Aerospace
Thinking about what will happen to our products when they reach their end of life is critical for us to consider in the design phase. Bombardier has set up a partnership with the Consortium for Research and Innovation in Aerospace in Quebec (CRIAQ) to better understand end-of-life requirements and research new, commercially viable recycling technologies for aircraft. In 2012, Bombardier donated an aircraft to CRIAQ to aid the research and development process. As we learn more throughout this process, we are integrating end-of-life criteria in our design processes.
Julien Dezombre - Biography:
Julien Dezombre received a Master's degree in Chemical Engineering from Ecole Supérieure de Chimie Organique et Minérale, Cergy-Pontoise, France, in 2003. He then joined Airbus and participated to the implementation of a management system under ISO14001 and of an end of life demonstration project.
He joined Bombardier Aerospace in 2009 as Design for Environment - Engineering Professional. He successfully managed initiatives related to product based environmental improvement for new and legacy products, which includes collaboration with outside partners on research and development projects.

Challenges and Opportunities in the Application of Life Cycle Assessment for Sustainable BiofuelsGoretty Dias, University of Waterloo
Every week, it seems, a new life cycle assessment (LCA) appears for biofuels, claiming different environmental impacts and benefits. This presentation highlights some basic concepts and methodological issues in applying the LCA approach to biofuels. There are key environmental parameters in the life cycle of biofuels that create high uncertainty in the final results, such as land use change. I will draw from the literature and recent research to highlight data gaps and issues that affect the credibility of biofuel LCAs. Finally, I will address some high risk sustainability issues, and will introduce how industrial ecology concepts, along with application of LCA, can be an opportunity for more sustainable biofuels.
Goretty Dias - Biography:
Dr. Goretty Dias has a B.Sc. in Physical Geography and a Ph.D. in Atmospheric Science from the University of Guelph, and conducted her post-doctoral work in Environmental Engineering. Currently, she is a professor in the School of Environment, Enterprise and Development (SEED) at the University of Waterloo, and researches sustainability of bioenergy and food systems. Her areas of expertise include GHG measurement and analysis, air quality measurement technique development, and environmental modeling. In her academic and consulting work, Goretty has worked extensively with the Canadian agriculture sector to quantify and analyze air emissions, giving her a strong understanding of agricultural systems.
Since 2004, Goretty has been conducting LCA studies of the Canadian agriculture sector and bioenergy projects. Her recent and ongoing projects include: assessing LCA methods for Ontario's Low carbon fuel standard; developing an LCA module for biomass production in Ontario; LCA of short rotation willow in Ontario; and the use of agricultural residues and dedicated crops for electricity generation in Ontario. She is a researcher and a Board of Directors member in BioFuelNet, a Network of Centres of Excellence project.

Stewardship of the Earth's Freshwater with Land and Air; a Must for Sustainable Bioenergy DevelopmentHamed Mohammadifardi, University of Waterloo
Sustainable supply of feedstocks to bioenergy production systems, either from dedicated crops or residues, in turn has important implications on sustainable agriculture which is heavily dependent on water resources. Seventy percent of global freshwater withdrawals from rivers, lakes and aquifers are taken by the agriculture sector and the expected growth in biomass utilization for bio-economy development will increase the competition and pressure on water resources in the future [1]. Therefore a complete environmental impact assessment study needs to evaluate the impacts on these environmental resources.
Among the different environmental assessment tools, Life Cycle Assessment (LCA) is often used for quantification of environmental performance of different products and services. In most LCA studies of bio-energy and bioproduct, indicators such as Greenhouse Gas (GHG) emissions and energy use are often used, and freshwater use data are often not well represented [2]. However, recent studies have shown that in certain settings, the environmental impacts from freshwater resources may be very important, and neglecting them may offset the environmental benefits that are gained from climate change impact mitigation [3].
Therefore to do a complete LCA study of bioenergy and bioproduct systems, and avoid the shifting of environmental burdens from one environmental compartment to another, freshwater use impacts must be considered equally as important as GHG emissions or energy use. In fact, better stewardship of the earth's freshwater resources with land and air is not an option, but a must for the bio-economy to move toward its sustainable development.

Hamed Mohammadifardi - Biography:
Hamed Mohammadifardi is a PhD student within the School of Environment, Enterprise and Development (SEED) at the University of Waterloo. His doctoral study is concerned with the sustainability assessment of biorefinery systems, with emphasizes on their social and environmental performance. He received his first M.Sc. in Chemical Engineering with a focus on Waste management and Resource recovery from Borås University in Sweden, and his second interdisciplinary M.Sc. in Water System Technology from University of KTH, Stockholm. Following his career he began a research assistantship with Professor Goretty Dias in SEED where he is working on identifying the priority utilization pathways of biorefineries' systems in Canada as part of the BioFuelNet project.

Design for Environment at Bombardier AerospaceKahina Oudjehani, Bombardier Aerospace
Design for Environment is part of our business strategy to create advanced solutions for mobility and to bring to the market new products that have less impact on environment. For example, the CSeries commercial aircraft promises to deliver a 20% fuel burn advantage and thus 20% fewer CO2 emissions than any in-production aircraft in its segment.
A lifecycle management strategy is used at each stage of the product development to assess and reduce the environmental footprint: material selection, supply chain, manufacturing/ testing, product use and end-of-life considerations.
Kahina Oudjehani - Biography:
Kahina Oudjehani received a Master's degree (M.A.Sc.) in Chemical Engineering from École Polytechnique de Montréal in 2001 and a Bachelor's degree in the same field in 1997. She has cumulative experience of 13 years in environmental impacts assessment in different industries (Soil remediation, Telecommunication, Consulting and Aerospace).
She joined Bombardier Aerospace in 2008 as a Design for Environment specialist working for the CSeries program. She successfully influenced employees and suppliers to embrace the DfE strategy and collaborate to the Life Cycle Analysis. Early in 2011, she was promoted to the position of DfE Lead for the whole company where she is responsible, along with her team of 6 engineers, for integrating environmental concerns in the product design.
