Abstract

Renewable energy technologies contribute to the mitigation of climate change impacts through reduction in the emission of greenhouse gases (GHG) such as carbon dioxide. In this paper, a power plant located in Italy and fed with waste deriving from the olive oil industries is considered. The de-oiled pomace is characterised by lower caloric value equal to 4000 kcal/kg, by low content of nitrogen and sulphur and by the absence of heavy metals. A plant for the production of energy from biomass (de-oiled pomace and waste wood) is analyzed through a Life Cycle Assessment (LCA) approach. The carbon dioxide equivalent (kgCO2eq) emitted into the atmosphere is equal to 0.0597 kgCO2eq /kWh. The GHG emissions have been compared with those of a plant for energy production that uses refuse derived fuel (RDF) and with those of one that uses coal. The environmental benefits are quantified and the possibilities to develop the use of the pomace-to-energy at national level are estimated.
