<strong>Potash</strong> is essential for energy in Brazil<br />
Sugarcane<br />
• Uses 160kg/ha of potash<br />
per year, 55% of total<br />
nutrient required (In<br />
comparison, corn uses<br />
140kg/ha of potash, 31%<br />
of req’d nutrient)<br />
• Sugarcane is grown in<br />
about 8 million hectares of<br />
land, of which 55% of the<br />
harvest is used for ethanol<br />
production<br />
Milling and Refining<br />
• Once harvested, sugarcane<br />
is milled to collect the<br />
juice that contain 10-15%<br />
sucrose<br />
• Juice is filtered and refined<br />
Ethanol Production<br />
• Ethanol is produced by<br />
microbial fermentation of<br />
the sugar<br />
• Water is removed by<br />
distillation and dehydration<br />
Electricity Generation<br />
•Bagasse is burned to generate<br />
electricity for production<br />
plant and grid<br />
Ethanol<br />
replaces about<br />
50% of the fuel<br />
needed to<br />
operate light<br />
vehicles on<br />
gasoline<br />
Bagasse power<br />
generation<br />
represents<br />
4.1% of total<br />
installed<br />
capacity<br />
Ethanol Production Cost<br />
Sugarcane (Brazil): $0.83<br />
Corn (US): $1.14<br />
Ratio energy input to manufacture<br />
to energy output of ethanol<br />
Sugarcane (Brazil): 1:9.3<br />
Corn (US): 1:1.4<br />
