“…Prior to the operation, the glass bottle was flushed with nitrogen gas (N 2 ), sealed, and incubated at 35 ± 1 °C. Feeding was carried out once, and the stage was stopped when daily methane production ceased to deplete the residual biodegradable organic material present in it (methane production per day became less than 0.5% of the cumulative methane) [27,[31][32][33][34].…”

“…As shown in 1b). As discussed in [32], the BMP Th approaches tend to overstate the CH 4 production in comparison to the experimental methods due to the Buswell formula's inability to distinguish between biodegradable and non-biodegradable matter, with a portion of biodegradable material being allocated for cell growth, metabolites, and the protoplasm synthesis of microbes [52]. According to previous authors, CH has large variability values for cellulose (14.7-46.1%), hemicellulose (10.2-29.7%), and lignin (10.1-34.2%) [38].…”

Psychrophilic anaerobic digestion emerges as an appealing integrated solution for the management of agricultural waste, particularly for farmers in regions where the average temperature does not exceed 26 °C, as seen in coffee cultivation. Therefore, this study seeks to assess the biomethane potential of thermochemical-treated coffee husk through psychrophilic anaerobic digestion (C3-20 °C-w/pretreatment). To examine its viability, outcomes were compared with reactors operating at both mesophilic (C1-35 °C) and psychrophilic (C2-20 °C) conditions, albeit without the use of pretreated coffee husk. The C3-20 °C-w/pretreatment test demonstrated a 36.89% increase (150.47 NmL CH4/g VS; 161.04 NmL CH4/g COD), while the C1-35 °C test exhibited a 24.03% increase (124.99 NmL CH4/g VS; 133.77 NmL CH4/g COD), both in comparison to the C2-20 °C test (94.96 NmL CH4/g VS; 101.63 NmL CH4/g COD). Notably, the C3-20 °C-w/pretreatment trial yielded superior outcomes, accompanied by an associated energy output of 3199.25 GWh/year, sufficient to meet the annual energy demands of 494 residences. This marks an increase of 83 and 182 million residences compared to the mesophilic and psychrophilic AD of CH without pretreatment, respectively.

“…This model was based primarily on the reaction of biological degradation of complex polymer of organic matter or biomass also called methanation [24]. It has been the subject of numerous studies, articles and works to describe the general biochemical process, and to derive a simplistic macroscopic theoretical equation describing the conversion of any generic organic compound including nitrogen and sulfur (CaHbOcNdSe) into methane (CH4), carbon dioxide (CO2), ammonia (NH3) and hydrogen sulfide (H2S) using reaction (1) [25]. The simplified form of reaction (1) is the reaction (2), which we note A and B reactants, C, D, E and F products for development of the equation formula [19].…”

Biomass conversion technologies offer clean, sustainable, and renewable electrical energy from biogas that is leaking into landfills. This energy based organic largely replaces fossil fuels in industrial and manufacturing activities, without forgetting its contribution to the reduction of greenhouse gases. In this work, we have indicated the methodology to evaluate the energy recovery of biomass that any operator in this field of activity can use to anticipate, control, and improve the productivity and the functioning of the landfill controlled site. The interest of the use of a combinatorial methodology between the three experimental, theoretical and numerical models offers the advantages for anticipate all the problems, using the most common solutions such as installing all the possible equipment for the permanent verification of the site impermeability by detecting the oxygen content, of the degradation, of the mechanical system of the site by measuring the hydrogen sulphide concentration, of breakdowns detections, and loss of methane. In addition, the artificial intelligence applications can be implemented to predict of biomass feedstock properties, process optimization and design for biomass conversion, optimal utilization of bioenergy, and supply chain design and planning respectively using four categories.

This marks an increase of 100 and 217 residences compared to mesophilic and psychrophilic AD of CH without pretreatment, respectively.
