Low temperature anaerobic digestion of mixtures of llama, cow and sheep manure for improved methane production

Biogas production in anaerobic digestion in farm-scale units is typically performed under mesophilic conditions when used for producing domestic fuel and stabilizing animal waste for the use of digested manure as a fertilizer. Previous studies on the digestion of llama and cow manure have shown the feasibility of producing biogas under altiplano conditions (low pressure and low temperature) and of llama manure as a promising feedstock. The present study concerns the utilization of various mixtures of feedstocks from the Bolivian altiplano under low temperature conditions (18-25 degrees C). Laboratory scale experiments were performed on the digestion of mixtures of llama, sheep and cow manure in a semi-continuous process using ten 2-L stainless steel digesters to determine the effects of organic loading rate (OLR) and the feed composition. The semi-continuous operation of mixture of llama-cow-sheep manure proved to be a reliable system, which could be operated with good stability. The results suggest that in a system digesting a mixture of llama-cow-sheep manure at low temperature (18-25 degrees C) the maximum OLR value is between 4 and 6 kg VS m(3) d(-1). The methane yields obtained in the mixture experiments were in the range 0.07-0.14 m(3) kg(-1) VS added, with a methane concentration in the gas of between 47 and 55%. (C) 2008 Elsevier Ltd.
