Sugarcane mill - Wikipedia

Energy in the sugar mill. The remaining fibrous solids, called bagasse, are burned for fuel in the mill's steam boilers. These boilers produce high-pressure steam, which is passed through a turbine to generate electrical energy (cogeneration). The exhaust steam from the turbine is passed through the multiple effect evaporator station and used ...
