In times of search for water sustainability, it is essential to develop techniques and applications of water reuse methods in production systems. Water consumption in support areas of production of sugarcane chain is a key factor in water waste, whose potentiation studies of water footprint are incipient. The objective was to apply a water reuse system in Metarhizium anisopliae fungus production process aimed at optimizing the water footprint in the biological control of the cultivation of sugarcane. The study took place in fungal production laboratory of a sugarcane mill in the municipality of Nova Olimpia, State of Mato Grosso. It was quantitated water consumption and wastage associated with each activity through expeditious testing. The implementation of water reuse in the distillation system, main waste agent, reduced consumption by 51.21%. The production process has collaborated with about 97% of the monthly recycled water supply. This value could take individually all the monthly need for laboratory water (37,980 liters). Although not operate in closed circuit, if potability tests were adopted, the system could be modified for this purpose, making it sustainable. The adoption of water reuse measures, therefore, presented itself as an effective technique to water conservation and the improvement of the blue water footprint as a form of environmental sustainability measure.
