Water balance for the studied cases.

	Water consumption at the process	Conventional water reuse	Additional* water reuse	Total water intake necessary
	(m^3/t sugarcane)			(m^3/t sugarcane)
Case 1	17.2	93%	5%	0.48
Case 2	17.0	89%	7%	0.66
Case 3	17.0	89%	7%	0.68
Case 3L	18.5	91%	6%	0.71
Case 4	23.6	89%	9%	0.59
Case 5	16.7	90%	4%	0.97

 *Considering water recovery from vinasse and 85% recovery of the water from pretreatment.
