Summary: This study aims to determine the potential for biomethane production using an Anaerobic Sequential Batch Reactor to process slaughterhouse wastewaters. The results show that the reactor system has high methane production and biodegradation efficiency under optimal hydraulic retention times. Furthermore, pre-treatment of sludge and proper mixture with slaughterhouse wastewater can enhance biomethane production.

Summary: This study investigated enzymatic pre-treatment of grease trap waste for biodiesel production, reducing FFA levels through an esterification reaction. Results showed that using commercial enzymes in continuous-flow experiments achieved better FFA reduction than batch processes. The continuous-flow reactors were also more time-efficient, completing experiments in less than 1.5 days compared to 6 days for batch processes.

Summary: In this study, wastewater sludge from a poultry slaughterhouse treatment plant was converted into biodiesel through ultrasound-assisted in situ transesterification. Artificial neural network and response surface methodology were utilized to model and predict the process behavior with high accuracy. The biodiesel yield was found to be higher than that obtained from other types of sludge, showcasing the potential of ultrasound-assisted transesterification for biodiesel production.

Summary: This study successfully treated poultry slaughterhouse wastewater (PSW) by combining a biological pretreatment stage, an expanded granular sludge bed reactor (EGSB), and a membrane bioreactor (MBR). The system achieved contaminant removal rates exceeding 97%, meeting the discharge standards set by the City of Cape Town (CoCT). The EGSB and MBR played key roles in reducing concentrations of total suspended solids (TSS), chemical oxygen demand (COD), and fats, oil, and grease (FOG) to acceptable levels, demonstrating an effective and low-cost method for treating medium- to high-strength wastewater.

Summary: The study demonstrated that blending sludge oil with soybean oil through homogeneous alkaline transesterification reaction can produce high-quality fatty acid methyl esters (FAME). Under appropriate conditions, the blends of sludge oil and soybean oil can meet the parameters required by the National Agency of Petroleum, Natural Gas and Biofuels (ANP).

Summary: This study focuses on the energy potential of chickens and proposes the use of chicken fatty residues for biodiesel production. The transesterification process yields a biodiesel with a reaction yield of 85.6% and postcharacterization values consistent with biodiesel standards. The fatty residues from chickens can serve as a raw material for biofuel development.

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: The study focuses on predicting and optimizing the yield of biogas production in an anaerobic digester using co-digestion. Experimental data was used to develop a machine learning-based prognostic model, and the Response Surface Methodology (RSM) was employed to optimize the parameters. The results demonstrate that RSM coupled with machine learning is an effective technique for modeling, predicting, and optimizing biogas production yield.

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.
