How is biofuel made from sugar cane?

Even though the expression biofuel is widely used, it would be more accurate to speak ofbiofuel. Indeed, this type of fuel is not truly organic or non-polluting, it is only produced from agricultural resources, such as cane. sugar. However, this biofuel that is sugar cane completes the range of offers alternatives to fossil fuels, mostly offered to the public. We can deplore the low use of this energy resource in France.

Growing sugar cane to make ethanol

Thanks to the cultivation of cane, we can produce sugar which is used for food, but also fuel. Following a specific process of fermentationwe get a alcohol modified cane, ethanol. Indeed, it is necessary to grind the sugar cane then cook it, and subject it to a hydrolysis before cooling it. Then comes the stage of fermentation, then that of distillation in ethanol. You have to add a percentage of gasoline without lead to obtain biofuel. E85 super ethanol is thus composed of 85% ethanol and 15%unleaded petrol.

Biofuel: a manufacturing process where nothing is wasted

Everything is good in sugarcane. This plant offers the possibility of using all of its plant matterin particular bagasse which is the fibrous residue usable as combustible in order to feed boilers or electric turbines. Molasses can also be used for pharmaceutical purposes.
