Since the 6th century BC, cane sugar producers have crushed the harvested vegetable material from sugarcane in order to collect and filter the juice.
They then treat the liquid (often with lime (calcium oxide)) to remove impurities and then neutralize it.
Boiling the juice then allows the sediment to settle to the bottom for dredging out, while the scum rises to the surface for skimming off.
In cooling, the liquid crystallizes, usually in the process of stirring, to produce sugar crystals.
Centrifuges usually remove the uncrystallized syrup.
The producers can then either sell the sugar product for use as is, or process it further to produce lighter grades.
The later processing may take place in another factory in another country.

Sugarcane is a major component of Brazilian agriculture; the country is the world's largest producer of sugarcane and its derivative products, such as crystallized sugar and ethanol (ethanol fuel).
