Psychrophilic anaerobic digestion of guinea pig manure in low-cost tubular digesters at high altitude

Guinea pig is one of the most common livestock in rural communities of the Andes. The aim of this research was to study the anaerobic digestion of guinea pig manure in low-cost unheated tubular digesters at high altitude. To this end, the performance of two pilot digesters was monitored during 7 mon...
