Biomasa residual pecuaria: revisión sobre la digestión anaerobia como método de producción de energía y otros subproductos

Abstract: ResumenEl biogás producido por la digestión anaerobia de residuos pecuarios es una solución para la sustitución de la biomasa tradicional usada en iluminación y calor. Su uso presenta ventajas como la mejora en la productividad de las fincas, la reducción del impacto ambiental y el rompimiento de la dependencia a los combustibles fósiles y agroquímicos. Sin embargo, aún se tiene poca difusión en las zonas rurales de Colombia, principalmente por el desconocimiento de las potencialidades y los beneficios. Por ta… Show more

“…In tropical countries there is a great diversity of plants with these characteristics, among them Tithonia diversifolia (Hemsl.) Gray ( 1883), which can be used in more environmentally friendly environments, with better responses in animal welfare and better feed conversion, which could contribute to more competitive livestock systems (Parra-Ortiz et al, 2019;Cabrera-Núñez et al, 2019). In this sense, there is evidence that species of non-legume plants such as Tithonia diversifolia accumulate similar nitrogen in their leaves as legumes, have high levels of phosphorus, high number of roots, good ability to take up the few nutrients from the soil, wide range of adaptation, tolerate conditions of acidity and low fertility in the soil, it can withstand pruning at ground level, it has fast growth and low demand for inputs and management for its cultivation.…”

“…Se recomienda que la biomasa residual cuente con una proporción de C/N de 20% -30%; mantener un pH de 7 -8.5 y una temperatura en el biodigestor entre 20°C a 28°C [2], [21]. También se pueden someter a pretratamientos de tipo térmico, químico o mecánico para mejorar la calidad del tamaño de la biomasa y así aumentar el área superficial de contacto [25].…”

“…Metanogénesis: las bacterias metanogénicas transforman en metano, dióxido de carbono y agua a las sustancias generadas en la anterior etapa. Además genera un subproducto llamado digestato o remanente rico en nutrientes que puede ser usado como fertilizando o abono orgánico [15], [25], [27].…”
