Nigeria is a major importer of brown sugar, an important food source that can be manufactured from sugarcane locally available. To serve the purpose of designing a sugar manufacturing plant, this paper develops a plant-wide model for obtaining brown sugar from sugarcane. This model comprising material balance equations accounts for various processes involved in the manufacturing such as milling, filtration, evaporation, crystallization and drying. GAMS, an algebraic modelling tool, was employed to solve the model. From a basis of 100 tonnes of cane per day, a simulation result of 2000 tonnes of brown sugar per year compared excellently with literature. Therefore employing the model with a basis of 13 million tonnes of sugarcane, Nigeriaβs sugarcane plantation potential capacity, showed that the country can produce 500,000 tonnes per year, compared to the current capacity of less than 10,000
