“…The presence of Ba in an anaerobic system could be related to its content in industrial wastewater, such as crude glycerol (Danilović et al, 2017). Furthermore, the purposeful addition of fly ash as low-cost source of TE to anaerobic systems may entail the collateral supplementation of Ba (Gertner et al, 2017;Montalvo et al, 2017). A recent study showed that hydrolytic enzymes were stimulated in the presence of Ba (Muñoz et al, 2016), whereas the mechanism remained unresolved.…”

The sufficient presence of trace elements (TE) is essential for anaerobic digestion. Barium (Ba) is considered a non-essential trace element that can be collaterally added to digesters as part of low-cost trace element sources or because of its presence in some feedstocks, such as crude glycerol. In the present study, the impact of Ba supplementation (2-2,000 mg/L) on each stage of the anaerobic digestion (AD) process was evaluated using pure substrates (i.e., cellulose, glucose, a mixture of volatile fatty acids, sodium acetate and hydrogen) as well as a complex substrate (i.e., dried green

“…Commonly used technologies for energy and/or resource recovery from sewage sludge include anaerobic digestion, incineration, pyrolysis and gasification (Raheem et al, 2018). Anaerobic digestion is among the more widely employed processes for sludge stabilization, owing to its relatively high methane production capacity, lower energy consumption, and the ability to deactivate pathogens in biomass (Montalvo et al, 2017). In order to balance the C/N ratio, which significantly impacts biogas production, sewage sludge could be co-digested with various organic substrates such as a range of food wastes (Mehariya et al, 2018), animal wastes (Borowski et al, 2013) and other organic wastes (Elalami et al, 2019).…”

The 2 nd International Conference on Technologies & Business Models for Circular Economy (TBMCE) was devoted to presentations of circular economy concepts, technologies and methodologies that contribute to the shift of business entities and society as a whole to a more responsible, circular management of resources. In the framework of TBMCE 2019, we presented the Strategic Research and Innovative Partnership -Network for the Transition to Circular Economy (SRIP-CE) as a platform for establishing a successful long-term public-private partnership. The conference program included panel discussions, plenary and keynote sessions, oral and poster presentations on the following topics: Sustainable energy, Biomass and alternative raw materials, Circular business models, Secondary raw materials and functional materials, ICT in Circular Economy, Processes and technologies. TBMCE 2019 was organized by Faculty of Chemistry and Chemical Engineering, University of Maribor and held in Portorož, Slovenia at the Grand Hotel Bernardin from October 24th to October 25th, 2019. The event was under the patronage of Ministry of Economic Development and Technology.

“…One of the most important microorganisms in the AD process is the methanogenic archaea, whose growth rate is slow. Several authors reported that trace element addition stimulates the growth and metabolism of these microorganisms and improves their anaerobic process and methane production 11,12 . According to van Hullebusch et al 13 .…”

BACKGROUND Fly ash is an important source of trace elements that can act as cofactors of enzyme systems and improve anaerobic digestion processes. However, its effect on anaerobic digestion using real wastewater has not yet been studied. In the present work, the effect of fly ash on the anaerobic digestion of real winery wastewaters was studied, by means of specific methanogenic activity assays and with a special focus on its effect on the specific methane production and the microbial communities present. Five fly ash concentration (25, 50, 75, 100, and 150 mg L−1) were supplemented under mesophilic conditions. RESULTS The results showed that 25 mg L−1 of fly ash improved the specific methane production by 18% compared to the control assay; meanwhile, a concentration of 100 mg L−1 of fly ash generated inhibition of the methanogenesis and a 20% specific methane production decrease with respect to the control experiment. The microbial community analysis verified that fly ash supplementation affected the bacterial communities, with a significant effect on acetogenic bacteria, such as Cloacimonetes and Firmicutes. CONCLUSION The addition of adequate concentrations of fly ash to the process can raise the relative abundance of some microorganisms and, consequently, could increase the specific methane production in the anaerobic digestion of winery wastewater. © 2021 Society of Chemical Industry (SCI).
