DuPontSA, a joint venture business venture between DuPont and Sabancı, picked up a national title at the 2003 CIA-Chemical Industires Association- Awards held at London's Hilton Hotel.

The Wilton-based team picked up the national Manufacturing Improvement Award- in the continuous or high-volume manufacturing category.

The team engaged the whole workforce to deliver a 30pc improvement in manufacturing output and production cost, a 25pc reduction in fixed costs and a 50pc reduction in recordable injuries.

Site manager Kevin Feeney said: "Winning this very prestigious award was a very proud moment for all of us here at DuPontSA Wilton site. Faced with significant business pressures, the whole workforce has rallied round and helped to transform the site into one that is genuinely competitive in the global market. Everyone here believes that our manufacturing performance is second to none- whether it be measured by safety, production, cost or customer service. However, to receive such an important external award as this is very gratifiying. It will serve to encourage us further in our journey towards manufacturing excellence."

DuPontSA announced earlier this year that it was investing £ 27.8m in its site at Wilton, which will secure the future for its 189 workers.

The company is upgrading its purified terephthalic (PTA) acid plant at Wilton.

Stephen Elliott, CIA director - trade and competitiveness, said: "DuPont Sabancı has demonstrated that a company-wide commitment to improvement in its manufacturing performance can result in significant bottom - line gains reinforced by further benefits in terms of health and safety."
