SAE Recognizes Joint DuPont Automotive, DENSO Technical Paper on Automotive Recycling Development Program

DETROIT, April, 12, 2005 - DuPont Canada Principal Research Scientist Dr. H.
Peter Kasserra and DuPont Engineering Polymers' Senior Research Scientist
Christian Leboeuf are among a team to be honored with the Society of
Automotive Engineering Arch T. Colwell Merit Award for a technical paper on
breakthrough automotive cradle-to-cradle recycling technology. 
               Authors Denise L. Carlson, DENSO Corp. USA; Hiroyuki Yamazaki
and Sunao Fukuda of DENSO Corp. Japan; Kasserra; and Lebeouf are being
honored for their work on the paper: "Application of Nylon Composite Recycle
Technology to Automotive Parts."
       The Colwell award, established in 1965, annually recognizes the
authors of papers of outstanding technical or professional merit presented
at a meeting of the Society or any of its sections during the calendar year.
Papers are judged primarily for their value as new contributions to existing
knowledge of mobility engineering. 
The paper outlines the results of a joint development program with DuPont
Engineering Polymers and DENSO Corporation that shows DuPont Composite
Recycle Technology can be one of the most effective recycling technologies
to help meet the European Union ELV (End of Life Vehicles) directive. 
The global team made and tested a prototype automotive radiator end tank
using 100 percent glass-reinforced nylon recovered from post-consumer
radiator end tanks.  Radiator end tanks were molded from the reprocessed
material, and subjected to many tests, including high-temperature creep,
high-pressure cycling, vibration and low-temperature impact.  Results were
very similar to those obtained with tanks made from virgin materials.
Dr. Kasserra, a 35-year DuPont employee, has held the position of team
leader for the DuPont Nylon Recycle Solutions Business, and he has
contributed numerous business and technology developments in nylon
intermediates and polymerization processes.  Dr. Kasserra graduated from the
University of Toronto with Bachelor and Master's degrees in Applied Science
in Chemical Engineering and earned his Ph.D. from the University of Ottawa
in Biophysical Chemistry. 
Dr. Leboeuf, a 26-year DuPont employee, is a Senior Research Scientist in
the Engineering Polymer Group and the Packaging & Industrial Polymers Group
for product and process development.  In addition to his work on Composite
Recycle Technology, Dr. LeBoeuf is credited with product and process
development of DuPont(tm) Zytel(r) HTN 501, Rigid Packaging structures, dual
ovenable PA66 plastic trays for frozen dinners and nylon fiber spinning
technology.  Dr. Leboeuf obtained Bachelor and Master's degrees of Science
in Organic Chemistry and a Ph. D. in Organic Photochemistry from Universite
de Montreal.
