In Memphis, Tenn., gas that was once flared to the atmosphere now is captured as an alternative fuel. In Fayetteville, N.C., collaboration between DuPont employees and local governments resulted in a 26-million-pound reduction in air pollution. And at dozens of other U.S. operating sites, employees are putting their talents to work to conserve energy and help achieve DuPont sustainability goals. These efforts recently received national recognition by the American Chemistry Council (ACC).
At the annual ACC Responsible Care® conference in Washington, D.C., 21 U.S. plant sites were recipients of the organization’s 2012 Energy Efficiency Awards for their work to reduce plant energy consumption and minimize energy-related environmental impacts. With more than 100 manufacturing sites with annual energy targets, DuPont employees are committed to seeking energy efficiency and renewable energy projects that deliver business and environmental benefits.
“As part of our sustainability goals, DuPont is committed to reduce global greenhouse gas emissions by 15% from the base year 2004, and reduce our use of non-renewable fuels by 10% per dollar of price-adjusted revenue from the base year 2010,” said Dawn Rittenhouse, director of sustainable development for DuPont. “The projects honored by the American Chemistry Council, and many others underway in our company, are helping us meet our commitments. We are proud to be honored by the American Chemistry Council.”
DuPont was awarded in three categories for specific projects that reduce energy demand, improve operating efficiency and improve the environmental impact of U.S. manufacturing facilities.
DuPont Chemicals & Fluoroproducts earned the Energy Efficiency – Corporate Business Unit honor for reducing energy consumption by 15% through a three-year effort that involved the implementation of more than 190 energy reduction projects at 21 U.S. plant sites.
The Memphis, Tenn. site earned the Significant Improvement in Manufacturing – Plant Site honor for implementing a project that allows the use of a manufacturing byproduct gas stream for an alternative fuel in place of natural gas by a neighboring manufacturing site. The project complies with all applicable environmental regulations and site permits. Previously the byproduct gas stream had been burned in a flare, so the project not only improves energy efficiency, but also reduces the environmental impact of the industrial park.
The Fayetteville, N.C., site earned the Public Outreach – Plant Site honor for a project to convert the site’s boiler from fuel oil to natural gas. This project resulted in net reduction of 25.8 million pounds of carbon dioxide emissions and 811 pounds of sulfur dioxide emissions each year. The project was the result of a collaboration between the Fayetteville site and North Carolina state and local officials to install a 10-mile natural gas pipeline to supply manufacturing operations in the area.
