Lafourche Sugars
LLC-Leighton Factory requested a renewal permit. The
Leighton Factory is a raw sugar mill that processes sugarcane and produces raw sugar
and final molasses. Sugarcane is crushed
in the mill to extract its juice. Juice
is clarified and evaporated to thick syrup, which is further concentrated to
cause crystallization. Raw sugar
crystals are separated from the mother liquor in centrifuges; the liquor is
returned to process for additional concentration and extraction of raw
sugar. After recovering as much sugar as
possible from the mother liquor, the resulting final molasses (blackstrap) is
stored for sale.Testing requirements have been added to Boilers 1, 3, and 4 as
well as updates to federal and state regulations.
