Assessing Lignocellulosic Bioenergy Systems Using LCA — A Case Study

The following section provides a recent example for applying LCA in a bioenergy context: Following scheduled power cuts in 2007 due to outdated electricity infrastructure and low capacities of electricity generated, decision makers of the Cape Winelands District Municipality (CWDM), South Africa, seeked to investigate implementing local renewable bioenergy systems. By introducing alternative energy systems, the aim was to improve energy security and to reduce the dependency on the national energy supplier, ESKOM, while minimising the environmental impacts. A previous study (Von Doderer and Kleynhans 2010) identified bioenergy systems using lignocellulosic biomass grown in a short-rotation system as one of the most promising options for the CWDM. Thus, the LCA approach was used to determine the environmental performance of viable lignocellulosic bioenergy systems.
