Summary: Studies on biogas production from different organic materials in anaerobic conditions are conducted worldwide, with key parameters including raw material potential, production processes, economic analysis, and environmental impacts. Chicken manure is a significant raw material in biogas production, with research showing the potential for producing 8.58 million m(3) of biogas annually from processing about 110,000 tons of waste. This process also generates 17 GWh/year of electricity, 16 GWh/year of thermal energy, and reduces CO2 emissions by 13.86 thousand tons/year.

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: Perennial energy grasses (PEGs) have been recognized as a significant direction for the development of biomass energy due to their high yield, adaptability, and lack of competition with food crops. However, efficient digestion of PEGs faces challenges related to feedstock properties, such as recalcitrant structures. This review focuses on recent research on anaerobic digestion of PEGs and explores essential aspects for enhancing digestion performance, including grass types and properties, different pretreatments, co-digestion with various co-feedstocks, dosing of additives, and reactor improvements.

Summary: In India, rural areas account for only 23% of national electricity usage, highlighting the need to expand access to electricity for sustainable development. Biomass, particularly in the form of biogas produced from organic waste, provides a simple and direct energy source for cooking, heating, and electricity generation in rural households. Biogas production offers a pathway to generate electricity in villages through technologies like Solid Oxide Fuel Cells, ultimately bringing power closer to rural communities.

Summary: This study investigates the effects of bioaugmentation on the co-digestion of cheese whey and manure in a continuous stirred tank reactor under in-situ biomethanation operations. The addition of Methanoculleus bourgensis in the mesophilic reactor resulted in a stable biomethanation process and increased methane production rate. On the other hand, the addition of Methanothermobacter thermautotrophicus in the thermophilic reactor did not improve biogas upgrading performance.

Summary: In this study, biochar was produced from potato, rape, and wheat straw at 600 degrees C, and then added to a batch anaerobic digestion (AD) system to improve biogas yield. The results showed that the three straw biochars increased cumulative methane production compared with the control group. Potato straw biochar presented the highest cumulative methane production. Significant differences in microbial communities between biochar and control groups were noticed, and the microbial community structure in the AD system was significantly related to the biochar properties. The addition of biochar increased the abundance of Methanobrevibacter in the biochar group.

Summary: The paper proposes a novel deep learning-based prediction framework, aTCN-LSTM, for accurate cooling load predictions. The framework utilizes a gate-controlled multi-head temporal convolutional network and a sparse probabilistic self-attention mechanism with a bidirectional long short-term memory network to capture both temporal and long-term dependencies in the cooling load sequences. Experimental results demonstrate the effectiveness and superiority of the proposed method, which can serve as an effective guide for HVAC chiller scheduling and demand management initiatives.
