Abstract: The term Sugar cane byproduct comprises primarily on bagasse, Molasses & Press mud. However, their contribution would be more or less 30, 5 & 3 % on cane respectively. While, cumulative reflection remains 37– 38%. Principally, byproducts contribute to curtail cost of production to measurable & even survival extent. Amongst all, bagasse due to their 30% larger share has greater opportunity is utilized as prime byproduct to reduce cost with energy efficiency. By & large, bagasse itself utilize to generate power production on cheapest cost as compared to other sources of fuel. Currently, country – wide sugar industry, utilized bagasse to generate power @ 10 - 12 KG/KWH for self-generation. However, Cogeneration can reduce its consumption to 5 KG/KWH which is tremendous opportunity for sugar industry to make it proficient (Its Cogen mode steam consumption of extraction – condensing turbines having parameters 110 bar/ 540 Celsius with power output of 31.2 MW consumed steam at 5 Kg/KWH) With latest techniques steam consumption can be reduced from conventional 50 to 36 – 42% on cane. In order to focus potential opportunities to save bagasse or energy, five distinct areas i.e. a) Mill house Electrification, b) Installation of FFE with integrated vapor distribution, c) capacity utilization, d) Milling equipment & finally e) Plant automation significantly contributes towards optimization with justified pay back.
