Summary: The study demonstrates that using low-cost digesters for organic waste and wastewater treatment can significantly reduce environmental impacts, particularly those related to water source pollution. The environmental impact categories of Freshwater Eutrophication and Marine Eutrophication were notably decreased in the anaerobic digestion scenario. Therefore, low-cost digesters could play a role in advancing the circular bioeconomy in the NCS production sector.

Summary: This study evaluates the energy and environmental performances of electricity generated from Italian anaerobic digestion coupled with combined heat and power plants. It finds that small and medium plants mainly fed by organic by-products have the lowest impacts. Compared to electricity from the grid, biogas electricity has the lowest contribution in some impact categories and largest in others. In terms of global warming potential and cumulative energy demand, the impacts of biogas electricity are about 35% and 38% of that generated by the grid.

Summary: This study provides an environmental and economic assessment of hydrogen production from biowaste and biomass using a life cycle perspective. Ten environmental impact categories are analyzed using SimaPro LCA software and CML-IA method. The results show that hydrogen production from biowaste has higher climate impact, photochemical oxidant, and freshwater eutrophication compared to biomass. However, it performs better in other impact categories such as ozone depletion, terrestrial ecotoxicity, abiotic depletion-fossil, abiotic depletion, human toxicity, and freshwater ecotoxicity. The sensitivity analysis indicates that feedstock ratio and energy source significantly influence the results, particularly in climate change, abiotic depletion, and human toxicity.

Summary: Studies on evaluating sewage sludge as a feedstock for thermochemical processes have made significant progress. It is important to determine the stage of sewage sludge treatment for incorporating thermochemical processes into wastewater treatment plants and configuring the optimal process scheme. Pyrolysis is a crucial process for resource recovery, producing bio-oil and biochar. The aim of this study was to determine the optimal process scheme for pyrolysis of different sewage sludges, and the conditions for maximum bio-oil yield were investigated using thermogravimetric analysis.

Summary: Different pretreatment technologies, such as low-temperature thermal treatment and ultrasonication, were investigated to increase biogas yield from sewage sludge. The study found that low-temperature thermal pretreatment showed the best performance in enhancing sludge solubilization and methane yield. LCA indicated that ultrasonication had the worst environmental impacts at laboratory scale, but could reduce greenhouse gas emissions, fossil depletion, and stratospheric ozone depletion at full-scale conditions.

Summary: This study evaluated the environmental and economic impacts of different scenarios for food waste and biogas digestate management in Shenzhen, China. The results showed that dry AD coupled with biogas digestate incineration had the best net environmental benefits, reducing 195 kg CO2 per ton of FW, and was the most economically feasible option. Dry AD scenarios exhibited better environmental benefits compared to wet AD, especially in terms of global warming, human toxicity, marine aquatic ecotoxicity, and photochemical ozone creation potential. Incineration was found to be the best post treatment option for biogas digestate.

Summary: This study used life cycle assessment to evaluate the environmental impacts of producing frozen green peas from conventional and organic farming. The results showed that conventional peas had a higher environmental impact than organic peas, although this was not uniformly observed across all farms. The cultivation phase of peas was found to be the most impactful, and anaerobic digestion of pea residues and improvements in processing and nitrogen use efficiency could reduce the environmental impacts. Therefore, this study emphasizes the importance of sustainable practices in minimizing the environmental impact of frozen pea production.

Summary: This study compared different treatment options for food waste in China using life cycle assessment and found that increasing anaerobic digestion treatment and stopping landfilling could reduce most environmental impacts by over 50%. Although anaerobic digestion is more environmentally friendly, it consumes more freshwater, so it is important to promote waste classification policies upstream and enhance resource utilization downstream.

Summary: The valorisation of forestry residues as renewable resources for energy and bioproduct production is gaining interest, but a holistic technical and environmental analysis is lacking. This study evaluated bio-oil, synthesis gas, and biochar production from spruce, pine, and larch residues under different pyrolysis conditions. The results showed that larch bio-oil production at 300°C had superior performance. The study also highlighted the energy-intensive nature of the pyrolysis process, but suggested that on-site syngas energy and biochar could offset energy requirements.

Summary: This study investigated the impact of the non-antibiotic pharmaceutical carbamazepine on antibiotic resistance genes (ARGs) during anaerobic digestion. The results showed that carbamazepine induced the enrichment of ARGs and increased the abundance of bacteria carrying these genes. It also facilitated microbial aggregation and intercellular communication, leading to an increased frequency of ARGs transmission. Moreover, carbamazepine promoted the acquisition of ARGs by pathogens and elevated their overall abundance.

Summary: This paper developed a machine learning model to predict the biochemical methane potential during anaerobic digestion. Model analysis identified lignin content, organic loading, and nitrogen content as key attributes for methane production prediction. For feedstocks with high cellulose content, early methane production is lower but can be improved by prolonging digestion time. Moreover, lignin content exceeding a certain value significantly inhibits methane production.
