A SUSTAINABLE SOLUTION TO ENVIRONMENTAL PLANT IMPROVEMENTS

CUTTING EMISSIONS WHILE CUTTING COSTS

DuPont employs effective solutions for emission control, waste management and energy usage, to great effect.

SUSTAINABILITY AT DUPONT DORDRECHT

MORE THAN TALK

SUSTAINABLE OPERATIONS ARE KEY TO LONG-TERM PRODUCTIVITY AND GROWTH

In force since 2005, the European emissions trading system has meant the Dordrecht site–one of the ten largest DuPont sites–has had to reduce emissions by

Reducing Energy and CO2 Emissions

One of the most significant energy savings projects involves a collaboration with HVC, an incinerator of community waste that is adjacent to the DuPont plant in Dordrecht.

The incinerator produces steam, which is fed into a heat exchanger filled with water. The water heated in this exchanger produces steam which is used in the production processes of DuPont .

HVC came to an agreement with DuPont to sell steam to the Dordrecht site on weekends. For DuPont, it has the dual benefit of saving fossil fuels and money.

Decreasing Water Consumption

Water recycling is another of DuPont Dordrecht’s key environmental policies.

As part of a

Finding new ways of reducing emissions gets more difficult every year the further down the road you go.”

Paul Meyers, Site Manager, DuPont Dordrecht

We see sustainable growth as a challenge… We do not believe that sustainability, productivity and profitability are mutually exclusive.” “

Paul Meyers, Site Manager, DuPont Dordrecht

The project provides our city with a good deal. And for DuPont, our collaboration with HVC means getting a step closer to achieving one of our internal sustainability objectives: saving 11 percent of energy by 2015.”

THE SUPPORTING STRUCTURE

In order to institutionalize improvements related to energy and environmental performance, each DuPont site employs a dedicated expert who tracks overall energy performance against corporate and societal standards.

DuPont™ Delrin®, a very impact-resistant plastic manufactured at Dordrecht, has managed to cut fresh water intake by

by improving efficiency at the site’s cooling tower.

This leader then constructs a team comprised of employees from diverse functions throughout the site. Together, they devise and implement specific initiatives aimed at reducing waste, and improving efficiency.

THE RESULTS

Dordrecht won the DuPont internal environmental excellence award in 2008 for a project that increased steam production, reduced the need to cool water and resulted in a significant annual cost saving.
