“…In a field study, biogas yield of 0.41 and 0.47 L g -1 VS loaded is conducted by co-digesting CM, chicken manure without or with maize silage around 50 % VS reduction in mesophilic condition (Yangin-Gomec and Ozturk 2013). The higher than 60 % VS-COD reduction is often reported by co-digestion organic household waste and industrial organic waste (Bah et al 2014;Bertin et al 2013;Comino et al 2012;Comino et al 2009;Corro et al 2013;Solli et al 2014).…”

“…Cattle manure has low C/N ratio of 11-14 the nutrients requirement for anaerobic bacteria (Hashimoto 1983;Hills and Roberts 1981). C/N ratios of cattle manure are observed between 5 and 26.5 (Bah et al 2014;Chen et al 2010;Corro et al 2013;Dias et al 2014;García and Pérez 2013;Lehtomaki et al 2007;Li et al 2009;Risberg et al 2013;Solli et al 2014).…”

This literature review surveys the previous and current researches on the co-digestion of anaerobic processes and examines the synergies effect of co-digestion with cattle manure. Furthermore, this review also pays attention to different operational conditions like operating temperature, organic loading rate (OLR), hydraulic retention time (HRT), chemical oxygen demand (COD) and volatile solid (VS) removal efficiency and biogas or methane production. This review shows that anaerobic mono-digestion of cattle manure usually causing poor performance and stability. Anaerobic studies were generally performed under mesophilic conditions maintained between 35 and 37°C. Organic waste loading rate generally ranges from 1 to 6 g VS-COD L -1 day -1 stable condition in anaerobic digester. Generally, studies show that HRT for co-digestion of fruit-vegetables waste and industrial organic waste appears to exceed 20 days. However, the anaerobic co-digestion process is generally operated at HRT of between 10 and 20 days. VS and COD removal efficiency usually reaches up to 90 % due to codigestion with different type organic waste. Methane-biogas production is generally obtained between 0.1 and 0.65 L CH 4 -biogas g -1 VS.

“…In Norway organic materials such as cattle manure and dead fish from fish farms are in large supply. In 2012 a loss of 27.4 million dead salmon was reported from Norwegian fish farms [ 1 ], and the total annual amount of organic waste in Norway is 1.45 million tons [ 2 ].…”

“…Ensilaged fish waste contains large amounts of fat and protein [ 1 ], making it an energy-rich substrate that is suitable for biogas production. However, high inputs of fat and protein to a biogas reactor may cause accumulation of ammonia and fatty acids, potentially yielding unstable methane production and biogas reactor failure [ 15 , 18 ].…”

BackgroundBiogas is a renewable energy carrier which is used for heat and power production or, in the form of purified methane, as a vehicle fuel. The formation of methane from organic materials is carried out by a mixed microbial community under anaerobic conditions. However, details about the microbes involved and their function are limited. In this study we compare the metagenomes of four parallel biogas reactors digesting a protein-rich substrate, relate microbiology to biogas performance, and observe differences in these reactors’ microbial communities compared to the original inoculum culture.ResultsThe biogas process performance during the startup phase of four parallel continuous stirred tank reactors (designated R1, R2, R3, and R4) co-digesting fish waste and cow manure was studied. The microbial composition of the inoculum (day 0) and the four reactors at day 59 was studied and compared using 454 FLX Titanium pyrosequencing. In the inoculum and the reactor samples, the Bacteria Clostridium and Syntrophomonas were highly abundant, and the dominating methanogen was the hydrogenotrophic Methanoculleus. Syntrophic prokaryotes frequently found in biogas reactors with high concentrations of ammonium and volatile fatty acids were detected in all samples. The species Candidatus Cloacimonas acidaminovorans of the candidate phylum Cloacimonetes (WWE1) increased in all reactors and was the dominating bacterium at day 59. In particular, this bacterium showed a very high abundance in R1, which distinguished this reactor significantly from the other reactors in terms of microbial composition. Methane production and the reactor slurry characteristics were monitored in the digestion period. Generally all four reactors operated stably and showed rather similar characteristics. The average methane production in the reactors varied between 0.278 and 0.296 L gVS-1, with the lowest production in R1.ConclusionsThis study showed that four parallel reactors co-digesting manure and fish waste silage operated stably during a startup phase. Several important Archaea and Bacteria degrading the protein-rich substrate were identified. In particular, microorganisms involved in syntrophic methane production seemed to be important. The detailed characterization of the microbial communities presented in this work may be useful for the operation of biogas plants degrading substrates with high concentrations of proteins.

“…Anaerobic co-digestion is a process in which organic waste is mixed with sewage sludge in an anaerobic tank to decompose biologically degradable organic matter into methane and carbon dioxide in the absence of molecular oxygen [5]. This anaerobic co-digestion process can increase sludge digestion efficiency of the anaerobic digester to reduce sewage sludge, resulting in reduced sludge treatment cost, and the produced biogas can be used as an alternative energy source [3,6]. In addition, anaerobic co-digestion can reduce construction cost when using existing digesters, and the digestion efficiency of the digester can be increased by injecting organic materials into a sewage treatment plant operated at low load [7].…”

The purpose of this study was to investigate the effects of acidogenic fermentation broth with rice bran (RFFB), tap water (TFFB), or raw fishery by-products (FBs) on sludge reduction and biogas production in an anaerobic co-digestion process. Acidogenic fermentation of FBs with rice bran was faster and produced more volatile fatty acids than that with tap water. Reduction efficiencies for chemical oxygen demand, volatile solids, and total solids were highest in RFFB. In the kinetic analysis, λ (d), which represents the duration of the lag phase, was shortest with RFFB (1.09 d) and highest in sewage sludge (8.86 d). As the loading amount of volatile solids and chemical oxygen demand increased, the amount of cumulative biogas also increased. Amount of produced methane and energy recovery were highest with RFFB (5.71 kWh). Anaerobic co-digestion of FFB and sewage sludge allowed reduced sludge and recovered energy using the discarded waste as an organic carbon source.
