DuPont announced it has completed its purchase of MECS from affiliates of American Securities LLC. The transaction strengthens the DuPont clean technologies portfolio and will provide access to additional high-growth markets, particularly in developing regions such as Asia Pacific, the Middle East, and Africa.

Per the agreement, MECS became a wholly owned subsidiary of DuPont and part of the company’s Sustainable Solutions business, effective December 31, 2010.

“We are pleased to begin 2011 by welcoming MECS into DuPont Sustainable Solutions,” said James R. Weigand, president, DuPont Sustainable Solutions. “This acquisition enables us to diversify our clean technologies portfolio in significant ways. As a result, we estimate an increase in the addressable market for our clean air and clean fuel offerings from approximately $200 million to $1 billion. This action also is aligned with our corporate goals that call for using our science and technology to protect people and the environment and to address the needs of developing regions.”

MECS is a leading global provider of process technology, proprietary specialty equipment and technical services for sulfuric acid producers. In addition, it supplies proprietary heat recovery systems that generate carbon-neutral energy from sulfuric acid plants.
