| Sugarcane is the most efficient crop in terms of biomass production, with a photosynthetic efficiency of 0.8 per cent under rainfed conditions or 1.1 per cent under irrigation, for an average 12-month crop in a tropical environment. Under these conditions, an efficiency managemed and irrigated crop can yield 100 tonnes of millable cane per hectare which corresponds to a total biomass of 148 T/ha fresh weight. This consists of 67.6 per cent net millable cane, 7.4 per cent dried leaves and 25 per cent of tops (young immature nodes) and green leaves. The total dry matter produced is about 42 tonnes and the total energy thus harnessed 757 GJ, which are equivalent to 27 tonnes of coal or 16 tonnes of oil. Under traditional systems of production primarily for sugar, 63 per cent of the dry matter biomass is exploited to produce sugar, scums, molasses and bagasse, as well as energy from the latter for the manufacturing process. However, there is more and more conviction that the future of agro-industries lies in a greated and optimum utilization of the crop biomass. Already in sugar cane there is considerable use of by-products and waste products. In particular, there is increased interest in co-generation of energy and recently several countries are investigating the use of trash in addition to bagasse for this purpose. This presentation examines the energy input/output balance in sugar cane cultivation taking into account the energy values of various components of its biomass, the energy requirements of different steps in the cultivation and sugar manufacturing process and discusses various issues regarding some of the options for a cost-efficient exploitation of the cane biomass for sugar and energy. | |
