Summary: The study evaluated the feasibility of using Maple Leaf Waste (MLW) to produce biofuel-bioenergy and chemicals for the first time. By analyzing different degradation stages and temperatures, it was determined that the pyrolysis temperature range for maximum bioenergy production is from 200 degrees C to 430 degrees C. The findings show that MLW has significant potential for bioenergy production and is suitable for co-pyrolysis with other waste and biomass feedstock.

Summary: This study investigated the thermal behavior and kinetic mechanism of microalgae and its model compounds to provide reference for thermal conversion of microalgae to produce energy products. Results showed that microalgae mainly pyrolyzed between 180 and 500 degrees C, with protein and carbohydrate chiefly pyrolyzing below 350 degrees C, while lipid violently pyrolyzed above 350 degrees C. The average activation energy for the decomposition of component models was in the order of OL > PT > SC, and the kinetic mechanism of microalgae and its components PT and SC was Reaction-order model.

Summary: A simple two-equation model is used to investigate thermal decomposition of a single cylindrical wood particle, analyzing the contribution of heat transfer and chemical processes during pyrolysis. The study discusses reaction rate and kinetic constant values for biomass, proposing a new approach for determining reaction rate. Chemical reaction time and heat diffusion time were evaluated for different particle diameters and temperatures, showing that at low temperatures, chemical reaction time is significantly longer than heat transfer time.

Summary: The pyrolysis of Iranian oak wood and waste plastics using different zeolite catalysts and ratios showed that pressurized pyrolysis with HZSM-5 catalyst provided the best de-oxygenation performance. During thermal pyrolysis, the melt polymer from plastics covered oak particles and formed a coke layer, increasing the thermal stability of remaining lignin.

Summary: The devolatilization kinetics of coal, poplar wood, and biomass blends were studied using TGA and FFR. The CPD model failed to accurately simulate the results, while the global model required the use of fitted values of various parameters to obtain agreement between simulated and measured data. It was found that the activation energy for wood was lower than for coal, and blending coal with 20% wood resulted in a decrease in activation energy. Furthermore, the devolatilization times for blended samples were similar to or even lower than that of wood, suggesting the presence of synergies.

Summary: This study investigated the kinetics of PET pyrolysis reactions at different heating rates (2, 5, 10, and 20 K min(-1)) using thermogravimetric analysis (TGA) data. Only one kinetic reaction was observed within the temperature range of 650 to 750 K. Five different model-free models were fitted to the experimental data to obtain the activation energy (E-a) and the pre-exponential factor (A(0)) of the reaction kinetics. The most suitable reaction mechanism was determined using the Coats-Redfern (CR) model equation with the help of a master plot.

Summary: Hollow cobalt nitrogen-doped carbon (H-CoNC) is proposed as an anodic catalyst for membraneless hydrogen peroxide fuel cells (HPFC) and enzymatic biofuel cells (EBC), demonstrating superior catalytic activity for hydrogen peroxide oxidation reaction (HPOR) due to its porous and hollow-shell structure, along with a large amount of isolated Co atoms and coordinate bonds with Co and nitrogen (Co-N-4). The improved mass transfer to the active site results in enhanced current density at the bioanode and higher maximum power density (MPD) for both EBC and HPFC when using H-CoNC compared to conventionally synthesized catalysts.

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.
