For this, animal species existing in the scenario is determined, since it will contribute the organic waste to the biodigester. The number of animals is also determined, considering the movement of the herd, which would make it possible to determine the biomass generated daily with the purpose of establishing the sizing of the appropriate biodigester technology and knowing the behavior of the economic and energy parameters. Among the main results obtained, it was evidenced that the installation of a tubular polyethylene biodigester is more feasible than the installation of a fixed dome biodigester, meaning an economic saving of 19,796 pesos for the concept of technology selection. The necessary volume of this technology must be 20 m3, making it possible to produce 190 kg/day of biofertilizers, which represent an economic contribution of 2,375 pesos (95 USD) constituting an added value, in addition to the energy and economic benefits to be obtained. Moreover, with the introduction of the selected anaerobic biodigestion technology, it is possible to generate electrical energy to drive a fodder mill, a refrigeration system, a mechanical milking system, lighting, electric fencing and a water pumping system, all which require the acquisition of a 35 kW biogas generator.]]></p></abstract>
<abstract abstract-type="short" xml:lang="es"><p><![CDATA[RESUMEN La presente investigación se orienta en la determinación de la factibilidad económica, ambiental y energética de la tecnología de biodigestión anaerobia adecuada para un agroecosistema lechero, establecido en la Granja Universitaria &#8220;El Guayabal&#8221;, perteneciente a la Universidad Agraria de la Habana. Para ello se determina la especie animal existente en el escenario, dado que aportará los residuos orgánicos hacia el biodigestor, también se determina la cantidad de animales, considerándose el movimiento de rebaño, lo cual posibilitaría determinar la biomasa generada diariamente con el propósito de establecer el dimensionamiento de la tecnología de biodigestor adecuada y conocer el comportamiento de los parámetros económicos y energéticos. Entre los principales resultados obtenidos, se evidenció que la instalación de un biodigestor tubular de polietileno resulta más factible que la instalación de un biodigestor de cúpula fija, significando un ahorro económico de 19 796 peso por concepto de selección de la tecnología; el volumen necesario de esta tecnología debe ser de 20 m3, siendo posible producir 190 kg/día de biofertilizantes, que representan un aporte económico de 2 375 peso (95 USD) constituyendo un valor agregado, además de los beneficios energéticos y económicos a obtener. Además, con la introducción de la tecnología de biodigestión anaerobia seleccionada es posible generar energía eléctrica para el accionamiento de: un molino forrajero, un sistema de refrigeración, un sistema de ordeño mecánico, luminarias, cercado eléctrico y un sistema bombeo de agua, requiriéndose para ello de la adquisición de un generador de biogás de 35 kW de potencia.]]></p></abstract>
