Summary: Management of chicken manure in Morocco has become a focus due to the increasing demand for chicken and eggs. The bioconversion of chicken manure into biogas can reduce the amount of manure while generating clean energy. Comparing with co-firing, pyrolysis, and gasification, anaerobic digestion of chicken manure was found to be superior in terms of energy gain.

Summary: This study developed a mathematical model based on Monte Carlo simulation to predict the energy potential of biogas produced in an up-flow anaerobic sludge blanket (UASB) reactor treating swine wastewater (SWW). Lab-scale experiments and literature information were used to determine the energy potential of SWW at different organic loading rates (OLRs). The model allowed an estimation close to reality, with reduced errors, making it a relevant tool for entrepreneurship and energy self-sufficiency projects.

Summary: This study investigated the effects of biological pretreatment on biogas production from lignocellulosic biomass and studied the combination effect with other pretreatment methods. The results showed that aerobic digestion was the only pretreatment method that could individually improve methane yield from pinewood, but combining aerobic digestion with mild thermochemical pretreatment could achieve even higher methane yield.

Summary: This study evaluates lipid extraction from algae and biogas production using thermo-chemical pretreatment, finding hexane as a suitable solvent with a 1.8% yield. Sodium hydroxide was found to be the most influential on biogas yield, with a predicted maximum yield of 740 ml/gVS under optimal conditions. Pretreated algae and corn husk produced 60% higher biogas yield than untreated algae, showing potential for mass application.

Summary: This study evaluated the combined effect of alkaline-thermal and mild ultrasonic pretreatments on the anaerobic digestion of chestnut shells. The treated shells showed a significant increase in biomethane yields compared to the untreated shells. The solubilization of lignocellulosic compounds and the increased solubility of lignin were found to be positively correlated with the biomethane yields.

Summary: Gasification kinetics of six chars from residual origin were studied under relatively low temperature, low CO2, and high H2O partial pressures. The Random Pore Model (RPM) showed the best fit to experimental results, but the selection of the reaction model depended on the ash composition, specifically the presence of alkali and alkaline earth metals. Chars with ash content higher than 30% wt. were modeled with the RPM model, while chars with the highest K/Si ratio required modified versions of the RPM to accurately predict reaction rates. Textural properties played a key role in determining reaction parameters, such as the pre-exponential factor and activation energy, for chars with similar ash content and composition.
