This study attempts to increase the value of this residual biomass, mainly for energy generation. To this end, a representative sampling of vine varieties and vineyards in the region was taken and later thermochemically characterized, measuring moisture, ash content percentage, elemental composition and higher heating value (HHV) among all sampled lots. From these tests, only the variety factor of the vine exhibited any statistically significant influence. A correlation has been formulated to express the higher heating value of vine shoots in terms of their elemental composition, obtaining an estimate with a mean absolute error of 1% and a near zero mean bias error. Finally, because the annual amount of vine shoots generated in the La Rioja region is known, the energetic potential of this biomass has been estimated at 1,400,000 GJ per year, and a map is presented to show the energy density of this waste material from each municipality.Cada a\u00f1o se generan miles de toneladas de sarmientos en la regi\u00f3n espa\u00f1ola de La Rioja, sin que se hayan desarrollado a\u00fan sistemas adecuados para un razonable aprovechamiento de los mismos. El presente estudio intenta revalorizar esta biomasa residual, principalmente desde el punto de vista energ\u00e9tico. Para ello, se ha realizado un muestreo representativo de las variedades y vi\u00f1edos de la regi\u00f3n y una posterior caracterizaci\u00f3n termoqu\u00edmica, obteni\u00e9ndose la humedad, el porcentaje de cenizas, la composici\u00f3n elemental y el poder calor\u00edfico para todos los lotes muestreados. As\u00ed se ha podido determinar que s\u00f3lo el factor variedad tiene alguna influencia estad\u00edsticamente significativa. Se ha formulado una correlaci\u00f3n que expresa el poder calor\u00edfico superior del sarmiento de vid en funci\u00f3n de su composici\u00f3n elemental, consiguiendo una estimaci\u00f3n con un error absoluto medio del 1% y un error de sesgo medio nulo. Por \u00faltimo, conocida tambi\u00e9n la generaci\u00f3n de sarmientos en el territorio de La Rioja, se ha estimado su potencial energ\u00e9tico en 1.400.000 GJ t\u00e9rmicos anuales y se ha confeccionado el mapa de la densidad energ\u00e9tica de este residuo por municipios.\u00a0<\/p>","protected":false},"featured_media":0,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","format":"standard","class_list":["post-611919","tnc_col_611521_item","type-tnc_col_611521_item","status-publish","format-standard","hentry"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v22.6 - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>Portal de Revistas<\/title>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/revistas.uc.cl\/en\/international-journal-of-agriculture-and-natural-resources\/energy-potential-of-vine-shoots-in-la-rioja-spain-and-their-dependence-on-several-viticultural-factors\/\" \/>\n<meta property=\"og:locale\" content=\"en_US\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"Energy potential of vine shoots in La Rioja (Spain) and their dependence on several viticultural factors - Portal de Revistas\" \/>\n<meta property=\"og:description\" content=\"Each year, viticulture generates thousands of tons of vine shoots in the Spanish La Rioja region without an adequate system for their use.
