Psychrophilic anaerobic digestion of guinea pig manure in low-cost tubular digesters at high altitude
(ELSEVIEREstados Unidos, 2011-03-29)
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. ...
Anaerobic co-digestion of animal manure at different waste cooking oil concentrations
(Univ Federal Santa Maria, 2018-01-01)
This study aimed to obtain the best dose of waste cooking oil inclusion for the co-digestion of substrates prepared with dairy cattle and swine manure in order to maximize solids reductions and biogas yield. Analyses of ...
Use of biogas digestates obtained by anaerobic digestion and co-digestion as fertilizers: Characterization, soil biological activity and growth dynamic of Lactuca sativa L.
(Elsevier, 2018-01-10)
Agro-industrial systems provide large quantities of organic wastes that could imply an important environmental risk. While manures can be easily treated by anaerobic digestion, horticultural fruit wastes generally cannot ...
Anaerobic co-digestion of rabbit manure and sorghum crops in a bench-scale biodigester
(Springer, 2020-12-16)
Any type of biomass can be used as substrate for biogas production, but the performance of the biodigestion depends on the composition of the feed, and no direct extrapolation of the yield of the process from one substrate ...
Biogas production and microbial communities of mesophilic and thermophilic anaerobic co-digestion of animal manures and food wastes in Costa Rica
(2022)
Biomass generated from agricultural operations in Costa Rica represents an untapped renewable resource for bioenergy generation. This study investigated the effects of two temperatures and three mixture ratios of manures ...
Performance of semi-continuous anaerobic co-digestion of poultry manure with fruit and vegetable waste and analysis of digestate quality: A bench scale study
(Pergamon-Elsevier Science Ltd, 2018-12)
Poultry manure (PM) can contain ammonium and ammonia nitrogen, which may inhibit the anaerobic process. The aim of this work was to evaluate the performance of anaerobic digestion of PM co-digested with fruit and vegetable ...
Evaluation of a novel anaerobic co-digestion system for disposal of dead swine and manure: An important tool in animal production
(2020-06-01)
Purpose The anaerobic digester for dead animals is the most eco-friendly and cost-effective way to dispose of this waste. The aim of this study was to evaluate the removal efficiency of organic matter and pathogenic ...
Contribute of crude glycerin to increase the efficiency of anaerobic digestion process of dairy cattle manure
(Wiley-Blackwell, 2018-07-01)
The objective of this study was to determine the optimal inclusion doses of crude glycerin in anaerobic co-digestion with dairy cattle manure processed at 10, 17, and 24 days of retention in order to maximize reductions ...
