Summary: The global trend of seaweed production and utilization for biofuels, specifically biogas, is on the rise. This article provides a comprehensive overview of the potential of seaweeds for biogas production, covering biomethane potential, process parameters, microbial shifts, and effective approaches to enhance digestibility and biogas production. The impact of seasonal variations on seaweed composition and the microbial community involved in anaerobic digestion are discussed. Strategies such as pretreatment, co-digestion, and additive supplementation are explored for maximizing biogas production. Further research on microbial dynamics and co-digestion is necessary for complete biomass utilization and biogas enhancement.

Summary: The increasing amount of seaweed accumulated in the coasts requires proper disposal or treatment. In this study, three different pretreatment methods were used on beach-cast seaweed to improve methane yield. The thermo-acidic pretreatment resulted in the highest increase, 78% higher than raw seaweed, while the alkaline pretreatment showed a 36% increase and the highest reduction in methane production cost.

Summary: Macroalgae can be grown without fertilizer, fresh water, or arable land. Pretreatment methods are needed to enhance the availability of macroalgae biomass to microbial degradation and increase biogas yield. This study summarizes different pretreatment methods and their merits and challenges, showing that these methods can improve biogas yield if the appropriate method is selected based on macroalgae species. However, pilot-scale studies assessing feasibility on a full-scale implementation are still lacking.

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: The study found that research on cheese whey is relatively recent, with the majority of publications from 2018 onwards. Twelve variables of the anaerobic cheese whey degradation process were identified and grouped into five factors: substrate, reactor configuration, digestate analysis, microbiological analysis, and inoculum. It was also identified that most of the anaerobic processes allow the implementation of the circular economy into the dairy sector.

Summary: The anaerobic digestion of food waste can address societal challenges such as the depletion of natural resources, climate change, and energy security. This study analyzed the performance of biogas systems in three Swedish plants, considering climate impact, primary energy use, nutrient recycling potential, and resource cost. The analysis found that all cases led to the production of low climate impact biomethane with significant nutrient recovery. Factors such as collection system, pretreatment efficiency, choice of energy system, and digestate treatment were identified as influencing the overall performance of these systems.

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.

Summary: This paper studies the thermal stability and decomposition of cork materials with and without silica aerogel filler. The results show that the decomposition is inhibited and the pyrolysis is significantly reduced with the addition of silica aerogel. This finding suggests that silica aerogel-infused cork may be a promising raw material for biofuel production with reduced environmental pollution.
