Energy and GHG balances of ethanol production from cane molasses in Indonesia

A life cycle assessment of fuel ethanol production from cane molasses in Indonesia, evaluating greenhouse gas emissions, energy inputs, and the impact of cogeneration and waste management.

• The life cycle greenhouse gas emissions for the production and use of ethanol from cane molasses are estimated at 29 gCO2e per MJ, representing a 67% reduction compared to gasoline emissions.
• The energy metrics for the production process include a Net Energy Value (NEV) of −7 MJ/l, a Net Renewable Energy Value (NREV) of 17.7 MJ/l, and an energy yield ratio (ER) of 6.1.
• Sensitivity analysis indicates that emissions and energy values are highly dependent on the price of molasses, ethanol yield, and sugarcane yield. Potential improvements in energy and environmental gains can be achieved through biogas recovery from wastewater treatment, surplus bioelectricity generation via efficient cogeneration using bagasse/trash, and fossil fuel substitution.
