It also answers to the need of fuel saving and of obtaining that production with minimum expenses from raw materials of national origin. This work is presented in three parts. Firstly, the technologies and methods used in Germany for biogas production are described. There, great-format plants are used which are adequate to generate heat, electricity and an organic fertilizer. Secondly, the particularities of these biogas plants are approached. And finally, their possible use in Cuba is analyzed. As a result, the study shows the state of the art in the use of biogas facilities of great-format to international and national scale, which is used to obtain heat, electricity and bio-fertilizers, minimizing the aspects of environmental contamination, in correspondence with UN Agenda 2030 of Sustainable Development, also adopted in Cuba.]]></p></abstract>

Este trabajo se presenta en tres partes, en las cuales: primeramente, se describen las tecnologías y los métodos utilizados en Alemania para la producción de biogás utilizando plantas de gran formato que propician: generar calor, electricidad y un fertilizante orgánico. Una segunda parte donde se aborda las particularidades de estas plantas de biogás. Finalmente, una tercera parte donde se analiza su posible utilización en el caso cubano. Como resultado del mismo, se muestra el estado del arte en la utilización de instalaciones de biogás de gran formato a escala internacional y nacional, los cuales se utilizan para obtener calor, electricidad y biofertilizantes, minimizando los aspectos de contaminación medioambiental, lo cual está en correspondencia con la agenda de desarrollo sostenible de nuestro país para la década 2020-2030.]]></p></abstract>
