The two sources of potential pollution from the starch
products industry are sulphur dioxide and dust emissions.
Roquette is demonstrating its active commitment to fighting
air pollution by developing techniques to counter
both.
To reduce the sulphur dioxide and dust emissions generated
by combustion in its boilers, the company is turning
to natural gas, a fuel with an insignificant sulphur
content. Several co-generation units have also been
installed, reducing the "greenhouse" effect
as a result of a better efficiency.
Air used for conveying and drying powders is carefully
filtered before discharge.
An analysis of the life cycle of starch products shows
the CO2 discharge from factories is less
than the CO2 taken from the atmosphere by
corn, wheat and potatos during the growth stage.
