“…This indicated that microorganisms domesticated by KW had better substrate adaptability and better buffering ability at high concentrations of VFAs. De Oliveira et al (2021) indicated that when the domesticated inoculum was used in AD of KW, the digestion system was stable with methane yield of 292.2 ± 9.8 mL/g VS at the organic loading of 20 g VS/L. This provided additional evidence that the domesticated microorganisms had superior adaptation to high organic loading.…”

Anaerobic digestion (AD) has been widely used as a promising technology for the treatment of kitchen waste (KW). The effects of several acidification-resisting methods were compared, which included the supplementation of trace elements (TEs) and zero-valent iron (ZVI) / powdered activated carbon (PAC), and the application of the sludge domesticated by acetic acid (HAc) and KW as inoculum. The results showed that the supplementation of TEs and ZVI/PAC at total solid (TS) content of 6% and optimal addition doses resulted in an increase in methane yield to 346 and 366 mL/g VS, respectively. In addition, the methane yields of 327 and 241 mL/g VS were obtained by applying the sludge domesticated with KW and HAc as inoculum, while the methane yield of the control was only 89.2 mL/g VS, representing a relative increase of 288%, 311%, 267%, and 170%. The acidification could be alleviated by applying these methods, and also the methanogenic profile was improved. Furthermore, microbial community analysis revealed that the enrichment of Methanosarcina, which enhanced the substrate utilization capacity and subsequently increased methane production, was achieved through the addition of TEs and ZVI/PAC, along with the application of sludge domesticated by KW.

“…Therefore, it can be a feasible alternative to obtain savings in process costs. However, the literature regarding the use of solid wastes from craft beer industries in anaerobic digestion (AD) is rather scarce when compared to other sources, such as food wastes [ 5 , 6 ], bagasse from plantation [ 7 ], cow, cattle, swine and chicken manure [ 8 , 9 ], and sludges from sewage and effluent treatment plants [ 10 ]. This practice becomes interesting in face of the continuous growing of environmental, social and corporate governance (ESG) practices; one of them, the reducing of the consumption of fossil fuels (coal, natural gas, oil and its derivatives) [ 11 ].…”

In this work, biogas was synthesized from malt enriched-craft beer bagasse with the objective to generate clean energy. Thus, a kinetic model based on thermodynamic parameters was proposed to represent the process with coefficient determination ( R 2 ) of 0.82. A bench-top biodigester of 2.0 × 10 –3 m 3 was built in glass, and equipped with sensors to measure pressure, temperature, and methane concentration. The inoculum selected for the anaerobic digestion was the granular sludge, and malt bagasse was used as substrate. Data were fitted to a pseudo-first-order model for the formation of methane gas using the Arrehnius equation as basis. For the simulations of biogas production, the Aspen Plus ™ software was used. Results from 2 3 factorial design experiments evidenced that equipment was efficient, and the craft beer bagasse showed great biogas production, with nearly 95% of methane yield. The temperature was the variable that showed most influence in the process. Moreover, the system has a potential for the generation of 10.1 kWh of clean energy. Kinetic constant rate for methane production was 5.42 × 10 –7 s −1 and activation energy 8.25 kJ mol −1 . A statistical analysis using a math software was performed and evidenced that the temperature played a major role in the biomethane conversion.

“…To date, a large number of published papers aim to describe biogas production of AD, considering only the last step of the process. Through simple kinetic equations, such as firstorder, logistic, Cone, and Gompertz model, cumulative methane production is successfully fitted and predicted for batch experiments [17][18][19][20][21]. However, this mathematical approach limits to describe biogas evolution over time without considering the connection between the generation of the final product and the organic matter consumption.…”
