Economic context
With beet containing between 16 and 19% sugar, and yields of around 10 to 11 tonnes of white sugar per hectare, metropolitan France produced 4.23 Mt (million tonnes) of white sugar in 2000-2001, with 35 factories whose average capacity in tonnes of beet per day is close to 11,769 t bett. / day. The number of sugar factories will continue to decline. Some industry...
