Nestlé's French unit is investing  €40m (US$53.7m) in modernising production technology at its lyophilised coffee plant in Dieppe, Normandy.

The Swiss group is planning to replace a lyophilisation tower which uses freon (chlorofluorocarbons), to lower temperatures to minus 40 degrees C by a cooling system based on ammoniac and carbon dioxide. The Kyoto protocol makes provision for the prohibition of freon by around 2010.

Work at the Dieppe plant is scheduled to take place between November 2005 and February 2006.
