Effect of biogas utilization and plant co-location on life-cycle greenhouse gas emissions of cassava ethanol production

► GHG emission reduction in cassava ethanol production depended on the plant type. ► Using biogas for steam generation is more effective than for electricity generation. ► Plants co-located with starch factories have advantages in relation to GHG emissions. ► Boiler efficiency is a key factor for improving the GHG emission performance.
