Analysis of the transient inhibited steady-state in anaerobic digestion of a semisolid from pretreated bovine slaughterhouse wastewater

“…Slaughterhouse wastewater (SWW) is a residue characterized by a high load of animal derivatives, such as blood and inedible tissues, and pathogenic organisms, making it a potential risk to animal and human health (Franke-Whittle and Insam, 2013;Cárdenas-Medina et al, 2020). Additionally, the large volumes of SWW produced become its management a challenge, as its improper and unsafe disposal can cause serious environmental issues (Arvanitoyannis and Ladas, 2008).…”

“…SWW treatment involves several processes, including anaerobic digestion (AD), composting, alkaline hydrolysis, and incineration (Harris and McCabe, 2015). Among these treatments, AD stands out as it has the additional advantages of nutrient recycling and methane production (Franke-Whittle and Insam, 2013;Cárdenas-Medina et al, 2020). Indeed, SWW is considered a suitable substrate for AD due to its high methane yield potential (Palatsi et al, 2011); however, the high protein concentration usually found in SWW can lead to AD inhibition as a consequence of ammonium (NH + 4 ) and longchain fatty acid (LCFA) accumulation, which are byproducts of protein and fat hydrolysis (Hernández-Fydrych et al, 2018).…”
