Abstract:
The present life cycle assessment (LCA) study analyzes the perennial and productive non-food biomass Sida hermaphrodita as a solid biofuel. In a cradle-to-gate-system different process chains for the supply and use of Sida hermaphrodita were considered: the combustion of chips and pellets produced from Sida hermaphrodita are investigated by LCA to identify the most favorable way of use. Both process chains contain the biomass cultivation, harvest and pretreatment, transport and storage, production of the solid biofuel and the combustion. The functional unit is the supply of 100 GJ thermal energy. Besides Sida hermaphrodita a comparison with alternative energy carriers like wood chips, wood pellets, wood logs and Miscanthus pellets is carried out. The results do not show considerable differences in the environmental impacts of chips or pellets produced from Sida hermaphrodita. Furthermore the results demonstrate Sida hermaphroditas’ competitiveness in comparison with alternative solid biofuels. This study gives a first insight into the future use of Sida hermaphrodita as a serious alternative to other energy plants.
