The industries considered are olive-oil mills, rice mills, wineries, dairy plants, breweries and wood, meat and nut processing plants. The methodology used is based on statistical data, and is integrated into a Geographical Information System (GIS) from which geo-referenced results are obtained. The waste-to-electricity technologies analyzed are: grate firing followed by steam turbine, co-firing in coal power plants and anaerobic digestion plus internal combustion engine. The combined potential for the agro-industrial residues in Spain is estimated at 2625 ktoe/year of primary energy (1.85% of the primary-energy consumption in Spain in 2008). Olive mill and wood processing residues have the largest energy potentials. Comparisons are presented with (partial) results from other studies. Considering only profitable plants, grate-firing followed by steam-turbine cycle is the conversion option with the largest potential, totaling 653 MWe and an electrical generation of 4.57 TWh (1.44% of the gross electrical generation in Spain in 2008). A complete sensitivity analysis is done to investigate the influence of the different economic parameters. A reduction by 50% of the investment costs of grate firing would increase profitable power to 1102 MWe (and production to 7.70 TWh). 000063375 540__ $$9info:eu-repo/semantics/openAccess$$aby-nc-nd$$uhttp://creativecommons.org/licenses/by-nc-nd/3.0/es/ 000063375 590__ $$a1.974$$b2010 000063375 591__ $$aENVIRONMENTAL SCIENCES$$b68 / 193 = 0.352$$c2010$$dQ2$$eT2 000063375 591__ $$aENGINEERING, ENVIRONMENTAL$$b16 / 45 = 0.356$$c2010$$dQ2$$eT2 000063375 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/submittedVersion 000063375 700__ $$aZubizarreta, Javier 000063375 700__ $$aRodrigues, Marcos 000063375 700__ $$0(orcid)0000-0002-2267-8598$$aDopazo, César$$uUniversidad de Zaragoza 000063375 700__ $$0(orcid)0000-0001-6205-5160$$aFueyo, Norberto$$uUniversidad de Zaragoza 000063375 7102_ $$15001$$2600$$aUniversidad de Zaragoza$$bDpto.
