Summary: This study found that the biochemical methane potential of water hyacinth and municipal solid waste in Mexico City could be effectively managed through anaerobic digestion and anaerobic codigestion processes. The substrate-to-inoculum ratio played a significant role in volatile solids degradation. Anaerobic digestion of municipal solid waste with a S:I ratio of 1:1 produced more methane than anaerobic codigestion, but the difference was not statistically significant. Overall, the research highlighted the potential of using anaerobic digestion for renewable energy production and addressing the issues associated with water hyacinth, municipal solid waste, and leachate.

Summary: This study investigated the structural differences of humic acids (HAs) derived from different feedstocks and their effects on anaerobic digestion (AD). The study found that HAs with higher carboxyl and phenolic hydroxyl groups showed greater inhibition effect on AD. Different feedstock-derived HAs exhibited variations in aromaticity and humification degree, confirming the influence of HA structures on AD.

Summary: Anaerobic digestion of lignocellulosic biomass has been studied with duckweed, switchgrass, and rice straw under mesophilic conditions. Co-digestion at a 1:1 ratio yielded better results than other ratios, especially in community-scale biogas digesters. Daily biogas production was highest for digesters containing rice straw and cattle dung, showing potential for practical applications.

Summary: This study investigated the effects of biological pretreatment on biogas production from lignocellulosic biomass and studied the combination effect with other pretreatment methods. The results showed that aerobic digestion was the only pretreatment method that could individually improve methane yield from pinewood, but combining aerobic digestion with mild thermochemical pretreatment could achieve even higher methane yield.

Summary: This research investigates the use of propionate-cultured sludge to enhance methane production from upflow anaerobic sludge blanket systems (UASB) treating fresh landfill leachate. The experimental results showed that the optimal OLR for UASB 1 without augmentation was 48.2 gCOD/L dot d, achieving a CH4 production of 4019 mL/d. On the other hand, the optimal OLR for UASB 2 with propionate-cultured sludge augmentation was 12.0 gCOD/L dot d, achieving a CH4 yield of 6299 mL/d.

Summary: The study evaluated marine macroalgae waste as feedstock for anaerobic digestion processes, finding that the highest biogas volume and methane concentration were obtained at a total solids content of 2.5% TS. The experiments showed an average of 43% COD reduction and 46% VS reduction after 57 days, corresponding to about 27% of the theoretical maximum methane production. However, inhibition of the process was observed when using 3.5% TS, likely due to the accumulation of volatile fatty acids.

Summary: Post-consumer bio-based textile wastes are garments or household articles made from manufactured bio-based textiles that are discarded by the owner. These waste materials should ideally be organically recycled, but difficulties in selective collection and sorting hinder the process. The diverse materials in waste textiles, including natural and synthetic fibers, pose challenges for bioprocessing.

Summary: Currently, there is a growing amount of poly(lactic acid) (PLA) waste in municipal waste due to the increasing production of bio-based polymeric materials. This study investigates the potential use of anaerobic digestion (AD) to treat PLA waste, focusing on the effects of thermophilic fermentation and hydrothermal and alkaline pretreatments. The findings show that pretreatments significantly increase methane production and shorten the overall time of maximal methane production. However, it is important to consider that methane production is not necessarily linked to the visible presence of PLA pieces.

Summary: Iron incorporation in biomass carriers at different percentages significantly affected the nitrogen removal efficiency and the abundance of Anammox bacteria. The addition of 5% iron carriers resulted in the highest nitrogen removal efficiency (up to 75%) and increased ammonium removal rate. However, the presence of 10% iron carriers inhibited ammonium oxidation rate. The long-term release of ferrous iron from the carrier structure accelerated the treatment of the digester supernatant.

Summary: Gasification kinetics of six chars from residual origin were studied under relatively low temperature, low CO2, and high H2O partial pressures. The Random Pore Model (RPM) showed the best fit to experimental results, but the selection of the reaction model depended on the ash composition, specifically the presence of alkali and alkaline earth metals. Chars with ash content higher than 30% wt. were modeled with the RPM model, while chars with the highest K/Si ratio required modified versions of the RPM to accurately predict reaction rates. Textural properties played a key role in determining reaction parameters, such as the pre-exponential factor and activation energy, for chars with similar ash content and composition.
