| Abstract |
The inadequate management of municipal solid waste can cause environmental and health issues, however the predominance of municipal biowaste and food waste make anaerobic digestion (AD) an attractive option for the treatment and recovery of organic matter. From AD two by-products with high potential use are obtained, such as methane gas (present in biogas) and the digestate, whilst the process contributes to a mitigation of the problems generated by final disposal. Nevertheless, the AD process is affected by different factors associated with environmental conditions, the substrate, inoculum and reactor and experimental configuration. This paper presents an analysis and reflection on the effect of the variables associated with these factors from a technological surveillance over the period 2009-2019. Among the most studied variables, are temperature (in the thermophilic and mesophilic ranges), pH, and nutrients, while evaluation on psychrophilic temperature conditions and the head space effect, are less studied. In addition, few studies have evaluated the simultaneous performance of different variables, which is of interest, when considered that their interaction can elucidate elements that lead to a greater approximation between the theoretical and experimental production of methane.
