DuPont recently received the 2010 Premio ECO Award in the Product Sustainability category for its role in a closed-loop recycling process for agrochemical multilayer bottles. DuPont Latin America president Eduardo Wanick accepted the award during an international ceremony in Säo Paulo, Brazil.

The “Virtuous Cycle using Fusabond” project relies on the unique characteristic of DuPont Fusabond coupling agent to compatibilize and bond dissimilar polymers in the recycling process. Fusabond also improves impact resistance, surface finish and processability of parts and films so the recycled product can be used to form other articles with little material loss and great added value.

 

In the award-winning “Virtuous Cycle using Fusabond” program, agrochemical multilayer bottles are recycled into high-value industrial applications - shown here in flexible corrugated pipes.

Empty agricultural chemical packaging is collected by the National Institute for the Processing of Empty Packaging (inPEV), launched by government mandate and initially supported by 22 founding companies, including DuPont. Since 2002, more than 150,000 tons of empty packaging has been collected, eliminating the need for 374,000 barrels of crude oil and more than 160,000 tons of CO2 equivalents.

Brazil is a leader in collecting used agricultural chemical packaging with a 95 percent collection rate, compared with Canada (73%), Germany (76%), France (66%) and the United States (30%).

The ECO Award, organized by Amcham (American Chamber of Commerce) and newspaper Valor Economico, was launched in 1982 and awards socially responsible companies and emerging sustainable practices.

“It is a great honor to be recognized not only for the environmental impact of this recycling program, but for the science behind it," Eduardo said. "Multilayer containers pose a great recycling challenge due to the variety of plastic materials used in their construction. Innovative programs such as these evolve when the entire value chain is engaged.

“DuPont contributes to global food production by providing products and services that help ensure food safety, higher crop yields and healthier foods,” Eduardo said. “DuPont is uniquely focused across the value chain allowing us to introduce customized solutions based on our holistic view of global food production. Reducing the negative effects on the environment requires collaborative innovation throughout the value chain focused on a common goal of a sustainable future.”
