Simultaneous Synergy in CH4 Yield and Kinetics: Criteria for Selecting the Best Mixtures during Co-Digestion of Wastewater and Manure from a Bovine Slaughterhouse

Usually, slaughterhouse wastewater has been considered as a single substrate whose anaerobic digestion can lead to inhibition problems and low biodegradability. However, the bovine slaughter process generates different streams with particular physicochemical characteristics: (SWW), offal (OWW) paunch (PWW). Therefore, this research aims assess co-digestion (AcoD) of SWW, OWW, PWW manure (BM) through biochemical methane potential tests in order reduce risk increase A model-based methodology was developed synergistic effects considering CH4 yield kinetics simultaneously. The AcoD BM OWW SWW enhanced extent degradation (0.64–0.77) above both (0.34) (0.46) mono-digestion. Mono-digestion showed by NH3, which reduced OWW. combination (PWW BM) high (OWW SWW) presented stronger than BM-PWW SWW-OWW mixtures. Likewise, multicomponent mixtures performed overall better binary Furthermore, allowed select best mixtures, also demonstrated energy economic advantages compared mono-digestions.
