Summary: Anaerobic co-digestion is an important technology for processing organic waste, recovering nutrients, and creating sustainable biofuel. However, the low biogas output and high installation costs limit its viability. This literature review demonstrates that anaerobic co-digestion produces more methane biogas than anaerobic digestion, and adjusting the waste-to-water waste ratio can increase methane production.

Summary: This study investigated the effects of co-digesting sewage sludge and horse waste and found that co-digestion produced more biogas compared to mono-digestion of sewage sludge alone. The methane production also increased in the second phase of digestion, which could be attributed to the absence of wood chips.

Summary: This paper reviews the waste-to-energy sector, emphasizing the processes and feedstock involved, particularly highlighting the potential of anaerobic digestion in reducing pollution from manure and slurry. The significant role of manure in producing biogas for electricity generation is discussed, with the possibility of producing over 1.615 TWh of electricity in the UK if most manure and slurry were processed through biogas harvesting.

Summary: In this study of anaerobic digestion of chicken manure with varying chlorotetracycline concentrations, it was found that extracellular polymeric substances (EPS) play a protective role against chlorotetracycline by forming complexes to decrease degradation and increase adsorption. However, there is also a potential risk to the soil ecosystem from the adsorbed chlorotetracycline on EPS in sludge.

Summary: This study evaluated the anaerobic digestion of agricultural waste, manure, and slaughterhouse residues from species typical of the Andes region, such as llama, vicuna, and guinea pig; quinoa, amaranth, and wheat straw. The highest methane production rates were achieved for flame manure and quinoa straw at an RSI of 1:2, with significant increases compared to an RSI of 1:1. The modified Gompertz model proved to be the best fit for performance analysis, with a constant difference of 7.06% between experimental and predicted values.

Summary: Anaerobic digestion technology is a feasible alternative for waste treatment and biomethane production in Cuba. The study showed that horse, rabbit, and goat manures have high methane potential, with rabbit manure being particularly attractive for domestic digesters. Furthermore, the use of horse manure for electricity generation could potentially replace a percentage of household electricity consumption, showing promise for future exploitation in the energy sector.

Summary: Kazakhstan has abundant reserves of natural resources and aims to reduce its dependency on coal, oil, and natural gas by developing renewable sources of energy, particularly renewable natural gas, to achieve net zero carbon emissions by 2050. A study analyzes the potential of biogas production using livestock and poultry manure as a source of organic matter, and suggests a policy based on agricultural land distribution to promote biogas production.

Summary: This study found that the addition of an appropriate amount of rice husk biochar (RHB550) can improve the anaerobic digestion process of food waste and increase methane production. However, excessive amounts of biochar can inhibit the digestion process. Adding RHB550 biochar can enhance the stability and methane yield. Increasing its concentration can further improve the organic loading rate in anaerobic digestion.

Summary: The addition of a top sand layer to leach bed reactors (LBRs) can facilitate the processing of drylot cattle manure containing up to 90% total solids without hydraulic failure. The system operated as a batch process for 42 days showed a mean total chemical oxygen demand (COD) reduction of 51.6% and a total volatile solids reduction of 44.7% in manure. The appropriate operational time for the system was found to be 14 days.

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.

Summary: This study investigated the impact of magnetite on the nitrogen cycle of pig manure biostabilisation. The addition of magnetite increased N2O emissions and decreased NH3 emissions during composting. It also increased the total nitrogen content but should be considered for its significant increase in N2O emissions in engineering practice.

Summary: This study investigated the operation of a 1000L microalgae-based membrane photobioreactor system for continuous secondary wastewater treatment. The research focused on a green microalgae strain called Desmodesmus sp. The study aimed to understand key trends and optimization strategies by conducting experiments in both summer and winter seasons. The findings showed that maintaining low cell concentrations during periods of light inhibition was beneficial for nutrient uptake rates. Effective strategies for enhancing algae-based wastewater treatment included cell mass recycling and adjusting dilution rates based on light availability.
