Summary: This study aims to enhance biogas production from anaerobic co-digestion (ACD) of EFB with POME by evaluating the effect of alkaline pretreatment of EFB, EFB-to-POME ratio, and temperature on methane yield. Results show that ACD performs 2.36 times better than mono-digestion of POME at mesophilic conditions, with the modified Gompertz model predicting process behavior with high accuracy (R-2 > 0.95).

Summary: This study investigated the effect of intermittent aeration on oxygen dynamics, organic matter degradation, and gas emissions in pig manure composting. The results showed that despite providing only half the volume and supply of oxygen compared to continuous aeration, intermittent aeration significantly improved oxygen utilization efficiency and reduced energy dissipation. There was no significant difference in organic matter degradation between intermittent aeration and continuous aeration. Additionally, intermittent aeration resulted in significant reductions in CH4, N2O, total greenhouse gas emissions, and NH3 emissions.

Summary: This study investigated the impact of interactions between microbial taxa on lignocellulose degradation during composting. The results showed that co-occurrence networks and bacterial-fungal interactions played significant roles in lignocellulose degradation, while microbial diversity had a relatively minor effect. Moreover, low-abundance taxa were found to influence microbial interactions driving lignocellulose degradation.

Summary: The increasing use of herbal essential oils has led to rapid global production and generation of large amounts of plant residues. Co-composting herbal residues with various wastes presents an eco-friendly and cost-effective waste management option, but the biologically active compounds in these residues may impact microbial activity and compost quality. Further research is needed to assess the potential antipathogenic effects of specific herb species in composts.

Summary: The addition of urea or urea combined with a microbial agent prolonged the fermentation time of the thermophilic period, leading to an increase in the abundance, diversity, and richness indices of fungi and bacteria during composting. Changes in community composition were highly correlated with total carbon, NO3--N, electrical conductivity, and pH, highlighting the beneficial effects of additives on straw composting.

Summary: This study investigates the effect of microbial inoculants (MIs) and different composting phases on NH3 emissions. The results show that NH3 emissions increase after adding MIs, and leachate ammonia volatilization contributes the most to NH3 emissions. MIs can reshape the community stochastic process and enhance NH3 emissions by promoting the co-occurrence between microorganisms and functional genes of nitrogen.

Summary: This study evaluated the variation of physicochemical characteristics during the co-composting of food waste and sawdust mixed biochar, and assessed the efficiency of biochar-composting combined amendment materials for reducing odor emissions and their maturity. The results showed that adding biochar could change the temperature, moisture, and pH during composting, and minimize the emissions of ammonia and hydrogen sulfide. The addition of 20% biochar resulted in the lowest ammonia and hydrogen sulfide emissions, with complete cessation of emissions on day 17. Furthermore, the compost was mature and non-phytotoxic. These findings highlight the effectiveness of biochar amendment in reducing odor emissions and enhancing compost maturity, with potential applications in agricultural fields.

Summary: Composting swine lagoon sludge is a challenge due to its high mineral and metal content. In this study, in-vessel aerated composting was used to evaluate the effects of sludge inclusion on composting process and end-product quality. The results showed that sludge inclusion had no significant impact on temperature, greenhouse gas emissions, and end-product quality. Both recipes lost carbon and nitrogen, but gained stability and a high germination index.

Summary: The production of organic fertilizer through aerobic composting of cattle manure is an important method of resource utilization. This study examined the effects of adding mature compost on the decomposition and microbial communities during aerobic composting of cattle manure. The addition of mature compost shortened the composting cycle and resulted in a lignocellulosic degradation rate of 35%. Metagenomic analysis revealed that this was due to an increase in thermophilic and organic matter-degrading microorganisms, which enhanced the activity of carbohydrate-active enzymes. The microbial community exhibited stronger metabolic functions, particularly in carbohydrate and amino acid metabolism, driving the degradation of organic matter. This study deepens our understanding of organic matter conversion and microbial community metabolism in livestock manure composting using mature compost, offering a promising technology for livestock manure composting.

Summary: This study investigated the effects of plant and soil microbial diversity on ecosystem multifunctionality (EMF) under different levels of grassland desertification. The results showed that both plant and soil microbial diversity declined with increasing desertification intensity, leading to a decrease in EMF. Plant and soil microbial diversity were identified as important predictors of EMF during desertification processes.

Summary: The drainage and deforestation of Southeast Asian peatland for agriculture led to high greenhouse gas emissions. This study compared GHG emissions from different land uses in Malaysian tropical peatlands and found that CH4 and N2O emissions were more affected by draining or rewetting than CO2 emissions. Forested sites had significantly higher CH4 emissions due to a higher water table, while rewetting-restored peatlands showed high decomposition rates for CO2 despite high water table levels. Drainage and fertilization in oil palm plantations led to high N2O emissions due to favorable conditions for microbial mediated N2O emissions.

Summary: This study analyzes the characteristics of process parameters in three lean gas ethane recovery processes and establishes a prediction and multiobjective optimization model for ethane recovery and system energy consumption. A new method for comparing ethane recovery processes for lean gas is proposed, and the addition of extra coolers improves the ethane recovery. The support vector regression model based on grey wolf optimization demonstrates the highest prediction accuracy, and the multiobjective multiverse optimization algorithm shows the best optimization performance and diversity in the solutions.

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.

Summary: This study uses survey data from the Loess Plateau in China to evaluate the impact of social interaction on the adoption of soil and water conservation (SWC) technology by farmers. The study finds that social interaction increases the likelihood of farmers adopting SWC, and internet use moderates this effect. The positive impact of social interaction on SWC adoption is more pronounced for farmers in larger villages and those who join cooperative societies.
