“…VS [24,60]. Experimentally, co-digestion of a mixture of cow manure and fruit and vegetable waste (50:50 by weight) produced 450 m 3 ton -1 VS at 35 ±0.5ºC [61], whereas a mixture of buffalo manure and maize silage (70:30 by VS content) at 35 ±1ºC produced 358.23 ±44.15 m 3 [62]. It has also been shown that meadow grass with its biochemical methane potential value of 388 ±30 mL g -1 VS has a yield increase of 114% when codigested with manure in a continuous stirred tank reactor [63], and when a mixture of solid cattle slaughterhouse waste, manure, various crops, and municipal solid wastes are batch-digested in thermophilic process, a methane yield of 655 mL g -1 VS was obtained [64].…”

“…The ratio of VFA to ALK is used to determine the stability of AD systems [28]. When the VFA/ ALK ratio is less than 0.4, the system is considered stable, whereas when it is between 0.4 and 0.8, the system is considered unstable.…”

To investigate the effects of organic loading rate (OLR) on performance and stability of mesophilic co-digestion of rice straw (RS) and chicken manure (CM), benchtop experiments (40 L) were carried out at OLRs of 3.0, 3.6, 4.2, 4.8, 6.0, 8.0, and 12.0 kg volatile solid (VS)/(m 3 ·day) with volatile solid (VS) ratio of 1:1 (RS/CM) which was based on batch tests. Anaerobic co-digestion was slightly and severely inhibited by the accumulation of ammonia when the digester was overloaded at an OLR of 6 and 12 kg VS/(m 3 ·day), respectively. The recommended OLR for codigestion is 4.8 kg VS/(m 3 ·day), which corresponds to average specific biogas production (SBP) of 380 L/kg VS and volumetric biogas production rate (VBPR) of 1.8 m 3 / (m 3 ·day). An OLR of 6-8 kg VS/(m 3 ·d) with SBP of 360-440 L/kg VS and VBPR of 2.1-3.5 m 3 /(m 3 ·day) could be considered, if an Anaerobic digestion (AD) system assisted by in situ removal of ammonia was adopted.

“…For animal manures this can be achieved by mixing with agricultural crops, as suggested by a number of researchers; this may also have the benefit of improving the volumetric methane production of the digester and thus its economic performance (Rajagopal et al, 2013). The co-digestion of cattle slurry with up to 50% fruit and vegetable wastes can provide a good methane yield (Callaghan et al, 2002) and an increase in methane production of 93% has been reported for chicken manure compared to its mono-digestion (Abouelenien et al, 2014). A theoretical study calculated that daily methane production could be improved approximately 1.2-fold by co-digestion of maize silage (MS) with cattle manure and CM (Yangin-Gomec & Ozturk, 2013).…”

The feasibility of co-digestion of chicken manure (CM) and maize silage (MS) without water dilution was investigated in 5-L digesters. Specific methane production (SMP) of 0.309 L CH 4 g -1 volatile solids (VS) was achieved but only at lower %CM. Above a critical threshold for total ammonia nitrogen (TAN), estimated at 7 g N L -1 , VFA accumulated with a characteristic increase in acetic acid followed by its reduction and an increase in propionic Methanogenesis was completely inhibited at TAN of 9 g N L -1 . The low digestibility of the mixed feedstock led to a rise in digestate TS and a reduction in SMP over the 297-day experimental period. Methanogenesis appeared to be failing in one digester but was recovered by reducing the %CM. Co-digestion was feasible with CM ≤20% of feedstock VS, and the main limiting factor was ammonia inhibition.
