In this review, the main properties of olive mill solid waste, primary by-product oil production, and its feasibility as a feedstock for anaerobic digesters operating at laboratory-, pilot- industrial-scales are discussed in detail. Nutrient addition thermal pretreatments were found to have potential address challenges arising from high carbon-to-nitrogen ratio, low pH, concentration phenolic compounds. Furthermore, co-digestion with different organic feedstocks has been identified one most promising options solve aforementioned problems seasonality nature while improving efficiency treatment plants that operate throughout whole year. The insights generated study show wastes animal farming be environmentally economically sustainable method digestion processes waste.

Anaerobic digestion (AD) has been recognized as one of the most viable options for treatment a wide range waste materials. Complex structure wastes is safely broken down to destroy pollutants and pathogens. Biogas produced by-product this process which considered clean energy resource. However, provision controlled environment microbial activities critical ensure required efficiency. This can only be achieved with efficient design vessels used anaerobic digestion, termed AD reactors. functions such mixing, hydrodynamics, multiphase interaction, heat transfer, temperature distribution bio kinetics are significantly affected by reactor shape, configurations, hence making it essential optimize before installation at large scale. Mostly, optimization carried out help lab scale experimentations testing protocols result in high costs repeating several experiments. Computational fluid dynamics (CFD) an applied mathematical tool helps understand predict dynamics, flow well species transport different domains. approach contributes minimize experimental while optimizing configurations less time. The current review presented summarize discuss core characteristics followed concerned CFD attributes. Research gaps challenges identified aspects design, configuration, flow, biokinetics machine learning approaches.
