Cost-opportunity analysis of the use of Posidonia oceanica as a source of bio-energy in tourism-oriented territories. The case of Alghero

摘要

The use of seaweed biomass for energy production is under consideration in several countries of the world. This paper, after a review of other scientific papers on the subject, aims at evaluating the pros and cons of the use of Posidonia oceanica as biomass source for anaerobic digestion (AD) in territorial contexts where the presence of large quantities of beached seagrass is also a problem for the tourism economy. The case chosen is the Sardinian town of Alghero.
