Potencial de los biodigestores de bajo costo o “Low-Tech”: soluciones de ingeniería y perspectivas para una mayor eficiencia
Palabras clave:
Biodigestores, Bajo costo, Condiciones psicrófilas, Biogás, Consorcios microbianos, Digestión anaerobia, Calentamiento solarResumen
Este artículo presenta una revisión de los biodigestores de bajo costo o baja tecnología y sus soluciones de ingeniería para mejorar la accesibilidad y eficiencia en el contexto de la digestión anaerobia. Se resalta la importancia de la comprensión profunda de los sistemas y procesos involucrados y su fácil adaptación a condiciones psicrófilas, en contraposición a la idea errónea de que la digestión anaerobia difícilmente puede ocurrir a temperaturas por debajo de 25 °C. Se destaca el papel de los consorcios microbianos psicrotróficos y su efectividad en la producción de biogás a temperaturas más bajas. Se analizan estrategias de ingeniería como la agitación neumática, la sumersión forzada, la calefacción solar pasiva y el desarrollo de biofilm para mejorar el rendimiento de los biodigestores de bajo costo. Este artículo desafía la idea de que los biodigestores de bajo costo o baja tecnología son inferiores.
