SCOUL built an Effluent Treatment Plant (ETP) to process the vinasse waste generated by its new distillery. The ETP implements anaerobic digestion process to avoid methane emissions due to the vinasse decomposition. The biogas collected is combusted into a boiler to produce heat. Project was inaugurated in 2013 and is operating since that time.
