POTENTIAL BIOMASS RESOURCES FOR ENERGY PRODUCTION IN SARDINIA (ITALY)

摘要

The aim of the present work is to study the energy production potential from forestry residues inthe Sardinian region. The study uses data pertaining to the Forestry Agency of the AutonomousRegion of Sardinia and ISTAT data regarding the evaluation of agricultural and agroindustrialresidues and proposes the disaggregation of the quantity of biomass on a territorial basis, usingthe four historical Sardinian provinces as a reference.Regional analysis of the woodland surface area, excluding the flat cultivated areas and themountain slopes covered in shrub-like vegetation, shows a relatively homogeneous distribution.With regard to the evaluation of agricultural and agroindustrial residues, a very thoroughassessment has been performed leading to the identification of an additional significant quantityof biomass.Evaluation of total biomass availability has identified a quantity equal to 179,000 tonnes of drywoodland timber per year and 163,000 tonnes of agriculture derived residues per year, mainlyconsisting of prunings and agroindustrial residues.The high productive pulverisation of biomass and the generally limited quantity allowevaluation of the feasibility regarding the creation of medium-capacity power plants producingenergy from biomass with an overall total of approx. 50 MW, equal to approx. 1.5% of theelectrical power supplied to Sardinia.
