 Identification of suitable lands
 Appropriate package of practices
 Economy of energy cane cultivation
 Logistic in harvesting, transport,
processing

32. • Economic
– Improved profitability of sugar industry
– Cogeneration is local: reduced network costs and
transmission losses
– Improved utilisation of marginal lands (drought,
water logging, salinity etc.,)
• Social
– Increased farming and rural employment
– Increased and quality electricity supply
• Environmental
– Reduced GHG emissions (compared to coal
burning)
– Benefits from CDM

33. • Acute shortage and high landing cost of feedstocks are
the major problems for biofuel industries.
• Erianthus arundinaceus and Saccharum spontaneum
have contributed significantly to the energycane
development
• 16 MW cogeneration unit established in the present
sugar industries requires 600 ha of energy plantations to
extend the duration for 100 days.
• With lignocellulosic conversion of bagasse into ethanol,
year round production of alcohol is feasible with captive
energy cane plantations.
• The energy canes developed are capable of growing in
marginal and abiotic stress condition where any food
crop cannot be cultivated economically.
