“…Given the growing interest in the removal of emerging contaminants, UASB reactors have been tested for the removal of pollutants such as antibiotics, estrogen, pesticides but also nutrients and heavy metals [ 24 , 34 , 72 , 82 , 89 , 92 ]. The results showed that the process generally guarantees a good coverage of the removal of these pollutants even if there are still some criticalities on the microbial load and on the overall toxicity of the effluent that requires a subsequent finishing treatment [ 86 ], as already highlighted previously in the literature [ 5 , 112 ].…”

“…Studies were also conducted on the effects of antibiotics, which may be present within the treated matrices, on granular biomass and on the responsiveness of UASB systems. UASB systems have not only proved effective in removing antibiotics but also ARGs present in the treated matrix [90,92,108]. This is a very topical issue considering that the resistance of pathogens to antibiotics is now a full-blown problem.…”

The interest in research on up-flow anaerobic sludge blanket (UASB) reactors is growing. The meta-analysis of bibliometric data highlighted the growing interest in four diverse topics: (i) energy recovery production; (ii) combination with other treatments; (iii) the study of processes for the removal of specific pollutants and, (iv) characterization of microbial community and granular sludge composition. In particular, the papers published in the first 6 months of 2021 on this process were selected and critically reviewed to highlight and discuss the results, the gaps in the literature and possible ideas for future research. Although the state of research on UASB is to be considered advanced, there are still several points that will be developed in future research such as the consolidation of the results obtained on a semi-industrial or real scale, the use of real matrices instead of synthetic ones and a more in-depth study of the effect of substances such as antibiotics on the microbiota and microbiome of UASB granular biomass. To date, few and conflicting data about the environmental footprint of UASB are available and therefore other studies on this topic are strongly suggested.

“…Nascimento added AQDS to a UASB reactor with a low hydraulic retention time (7.4 h) to remove sulfamethoxazole and methomyl, increasing their removal from 6 to 70% ( do Nascimento et al, 2021 ); Silva used CNT to enhance the removal of ciprofloxacin from anaerobic granular sludge and found that the removal of ciprofloxacin could reach 99% with the addition of 0.1 g/L of CNT. Further analysis of effluent biotoxicity showed that enhanced anaerobic treatment with CNT resulted in a detoxification rate of approximately 46% for Vibrio fischeri ( Silva et al, 2021b ).…”

“…For soluble electron shuttles, the enhancement of electron transfer efficiency between microorganisms and antibiotics is their main pathway of enhancing antibiotic removal. For example, riboflavin, a natural class of electron shuttles, can account for up to 75% of the total microbial electron transfer process ( Zhou et al, 2018 ); Synthetic AQS and AQDS as model quinone species can significantly enhance microbial extracellular electron transfer with the help of the cycle of their oxidation and reduction states ( do Nascimento et al, 2021 ).…”

The environmental and epidemiological problems caused by antibiotics and antibiotic resistance genes have attracted a lot of attention. The use of electron shuttles based on enhanced extracellular electron transfer for anaerobic biological treatment to remove widespread antibiotics and antibiotic resistance genes efficiently from wastewater or organic solid waste is a promising technology. This paper reviewed the development of electron shuttles, described the mechanism of action of different electron shuttles and the application of enhanced anaerobic biotreatment with electron shuttles for the removal of antibiotics and related genes. Finally, we discussed the current issues and possible future directions of electron shuttle technology.

“…This method has been suggested as an effective measure for helping to solve the anaerobic digestion problems and therefore improve the stability of the AD systems [143]. Recent research has also demonstrated that microaerobic digestion is an effective strategy to enhance the biotransformation of recalcitrant compounds and even organic micropollutants [147]. Oxygen dosage is the key factor to achieve the different advantages of the microaerobic processes [148].…”

The present work reviews the role of biogas as advanced biofuel in the renewable energy system, summarizing the main raw materials used for biogas production and the most common technologies for biogas upgrading and delving into emerging biological methanation processes. In addition, it provides a description of current European legislative framework and the potential biomethane business models as well as the main biogas production issues to be addressed to fully deploy these upgrading technologies. Biomethane could be competitive due to negative or zero waste feedstock prices, and competitive to fossil fuels in the transport sector and power generation if upgrading technologies become cheaper and environmentally sustainable.
