Life cycle assessment (LCA) of an energy recovery plant in the olive oil industries

To reduce the GHG emissions in the UE and to increase the produced energy it is important to spread out decentralized technologies for renewable energy production. In this paper a power plant fed with biomass is studied, in particular the biomass considered is the waste of the olive oil industries. This study focuses on the possibility of using the de-oiled pomace and waste wood as fuel. A life cycle assessment (LCA) of a biomass power plant located in the South of Italy was performed. The global warming potential has been calculated and compared with that of a plant for energy production that uses refuse derived fuel (RDF) and that of one that uses coal. The LCA shows the important environmental advantages of biomass utilization in terms of greenhouse gas emissions reduction. An improved impact assessment methodology may better underline the advantages due to the biomass utilization.
