DU PONT ANNOUNCES NYLON RECYCLING TECHNOLOGIES

 DU PONT ANNOUNCES NYLON RECYCLING TECHNOLOGIES
 WILMINGTON, Del., Oct. 9 /PRNewswire/ -- As part of its global


polymer recycling efforts, Du Pont (NYSE: DD) announced today that it is developing technology to efficiently return used nylon, from molded parts to fabric, into first-quality nylon.
 Du Pont has been developing several nylon recycling technologies that will handle 85 percent of all nylon used today, said Ross W. Fasick, senior vice president-polymers and automotive.
 The process will break the polymer down into its main ingredients, which will then be repolymerized to make nylon in any form and for any market where nylon is used.
 "It is conceivable," Fasick said, "that in five years time, we could see carpet fiber -- or even nylon pantyhose -- collected and chemically transformed into automobile components."
 Du Pont operates a nylon recycling plant in Glasgow, Del., with a capacity of more than 500,000 pounds per year. The plant is being used to evaluate the process of recycling post-consumer parts in collaboration with nylon customers in Europe and the United States. Capacity expansion depends on obtaining a sufficiently large and continuous supply of post-consumer "waste" nylon to feed the process.
 Du Pont is engaged in several pilot projects to recycle nylon automotive parts through conventional melt reprocessing. For example, automotive radiator parts and wheel covers are reprocessed into other molded articles at Du Pont facilities near Wilmington, and at Born, Limburg, the Netherlands.
 The new nylon recycling technology complements previously announced recycling technologies for other Du Pont polymers, including a proprietary methanolysis process to recycle polyester. Du Pont has invested more than $130 million in polymer recycling projects to help solve the growing solid waste disposal problem.
 "Technologically oriented companies like Du Pont must ensure that products are designed for disposal in an environmentally acceptable manner, including recycling and waste-to-energy recovery," Fasick said.
 To make recycling more economically feasible, Du Pont is working with customers, the general public, waste collection contractors, and automobile dismantlers, as well as local governments, to develop recovery and recycling infrastructures.
 Earlier this year, Du Pont recycled prototype car fenders using the depolymerization process and 126,000 plastic soda bottles from which recycled yarn was spun. From the yarn, 13,000 square feet of sails were produced for the three-masted tall ship "HMS" Rose, based in Bridgeport, Conn. The ship's sails demonstrate that Du Pont's technologies can produce high-value and high-performance materials from recycled polymers. "HMS" Rose participated in parades of tall ships in Puerto Rico, Philadelphia, New York, Boston, Newport, R.I., and New London, Conn., celebrating Columbus' discovery of America.
