The present work was carried out with the objective of presenting the current importance of work related to the optimization of anaerobic digesters using artificial neural networks. A scientometric methodological approach was used for a systematic review of the publications indexed in Scopus until 2023. The H index was used to evaluate the visibility and impact of the journals, authors, countries, and institutions with the highest levels of production and recognition in the field of study. This review also allowed us to analyze the interaction between groups and knowledge networks with the authors and institutions identified in the classification. The results show a significant increase in the number of publications between the years 1973 and 2023, which allow us to characterize on a scale the main dimensions of research, development and innovation related to the study of optimization methods of anaerobic biodigesters for the production of biogas from different waste such as that from the palm oil extraction process. The results show a significant increase in the number of publications between 2016 and 2023, a total of 2847 documents were found, where 95.64% are in English. The country that presents the most publications on the topic is China with a contribution of 19.28%, followed by the United States with 9.8%, India with 7.2% and Spain with 6.2% among others.

“…Within this biome are mainly cellulolytic bacteria (cellulose decomposers), amylolytic bacteria (break down starches), proteolytic bacteria (break down proteins), and methanogenic bacteria (produce methane) (Froidurot & Julliand, 2022;Hua et al, 2022;Palangi & Lackner, 2022). Excreta containing a biome rich in different types of bacteria makes them suitable as inoculums to generate biogas, in addition to being the main substrate for anaerobic fermentation (Sequeda Barros et al, 2023). One of the most essential bacterial groups in biodigesters is the methanogenic bacteria, which produce methane.…”

Background Biol is one of the best-known digestates, which occurs during anaerobic digestion in biodigesters to generate biogas, using animal manure and vegetable waste. This digestate type is used in organic agriculture due to its easy application, contributing simultaneously to the circular economy and food security. Methods The objective of this study was to characterize four types of biol, generated in four anaerobic biodigesters for biogas production implemented in northern Peru fed with manure: i) pig manure; ii) cattle manure; iii) horse manure; iv) cattle manure with coffee processing water. All the biodigesters implemented had the same design but worked under different environmental conditions. Descriptive and multivalent statistics were applied to the data obtained for the parameters evaluated. Results The biols obtained had different nutritional compositions, depending on the type of substrate used. The biol from pig manure was characterized by high concentrations of bacteria, the one from cattle manure had low concentrations of nutrients in general, the one from horse manure was rich in salts, and the one from cattle manure with coffee processing water was rich in organic matter. Conclusions These results showed that all the biols obtained can be used for organic agriculture. However, their selection will depend on the nutritional requirements of the type of crop and soil where the biols are to be applied.

“…Taking into consideration the significant energy consumption of the food industry, the application of such wastes in AD processes becomes a favorable choice. However, the anaerobic transformation of these wastes is still a technological problem [ 13 , 14 ]. They may contain substances that are recognized as AD inhibitors, e.g., terpenes, phenols and ammonium [ 3 ].…”

“…These residues, represented by OP, PL and BSG, were selected taking into consideration their significant amounts, and the ongoing problem with their effective management. Moreover, all of these substances indicated a potential for biogas production [ 13 ]. The co-substrates were added to municipal sewage sludge (SS), the main by-product of wastewater processing.…”

The main aim of this study was to evaluate the effect of the addition of selected industrial food wastes on the fate of micro- and macro-elements within an anaerobic digestion process (AD), as well as define the relationship between their content and AD efficiency. Orange peels, (OP), orange pulp (PL) and brewery spent grain (BSG) were used as co-substrates, while municipal sewage sludge (SS) was applied as the main component. The introduction of co-substrates resulted in improvements in feedstock composition in terms of macro-elements, with a simultaneous decrease in the content of HMs (heavy metals). Such beneficial effects led to enhanced methane production, and improved process performance at the highest doses of PL and BSG. In turn, reduced biogas and methane production was found in the three-component digestion mixtures in the presence of OP and BSG; therein, the highest accumulation of most HMs within the process was also revealed. Considering the agricultural application of all digestates, exceedances for Cu, Zn and Hg were recorded, thereby excluding their further use for that purpose.
