“…These yield results are in agreement with previous research by Cuetos et al [8] and Bayr et al [32]. Although the operating conditions were not identical in those studies, methane yields from similar wastes ranged from 400 to 700 NmL CH 4 /g VS.…”

AbstractDifferent mixture ratios of solid cattle slaughterhouse wastes (SB), manure (M), various crops (VC), and municipal solid wastes (MSW) were investigated for biogas production. The objective was to explore possible significant synergistic effects obtained from the combination of these different substrates. The performance of the process was assessed in thermophilic anaerobic batch co-digestion assays, using a four factor mixture design and methane yield (Y CH4 ) and specific methane production rate (r sCH4 ) as response variables.The highest methane yield, 655 NmL CH 4 /g VS was obtained when equal parts (ww) of SB, M, VC, and MSW were combined, while the combination of SB, M, and MSW resulted in the highest specific methane production rate (43 NmL CH 4 /g VS/d). A mixture design model was fitted to data in order to appraise synergistic and antagonistic interactions. Mixing all four substrates resulted in a 31% increase of the expected yield which was calculated from the methane potential of the individual fractions, clearly demonstrating a synergistic effect due to more balanced nutrient composition enhancing the anaerobic digestion process. However, no significant antagonistic effects were observed. In order to maximize both response variables simultaneously, a response surface method was employed to establish the optimal combination of substrate mixtures. The statistical results and analysis of the biological process gave a coherent picture of the results.

“…Moreover, benefits like higher maximum specific growth rate of microorganisms (l max ), and therefore better organic matter degradation in a shorter operating time [126], higher colour removal efficiency [128], more favorable disinfection capability, improved AD steady state stability [129], and being more feasible for co digestion approaches than mesophilic processes [130] can be expected by operating under thermophilic conditions. Yilmaz et al (2008) [90] studied the performance of two AFs under mesophilic (35°C) and thermophilic (55°C) conditions for the treatment of a paper mill wastewater.…”

“…Thermophilic AD shows several advantages such as higher loading rates of organic feedstock and a smaller pathogen degree [6]. Nevertheless, mesophilic AD would have a lower volatile fatty acid (VFA) concentration (especially propionate) and could usually support a higher organic loading rate (OLR) [7,8]. In general, OFMSW has a mutable complicated composition in the form of proteins, lipids, carbohydrates, and cellulose [9].…”
