Summary: The objective of this study was to assess the effects of mixing different fractions of organic waste (fruit and vegetable, meat, and fish) during anaerobic digestion. Batch experiments compared the digestion of each fraction individually to mixed fractions, focusing on gas generation and process performance using H2 as an indicator. Results showed that the optimal mixture was an equal proportion of all fractions, resulting in a balanced composition, a 58% faster process, and a 12% increase in methane production. It was also found that mixtures increased hydrolysis speed, with meat fraction mixtures increasing hydrolysis rate by 148% and buffering acidification inhibition.

Summary: This study evaluated the anaerobic digestion of agricultural waste, manure, and slaughterhouse residues from species typical of the Andes region, such as llama, vicuna, and guinea pig; quinoa, amaranth, and wheat straw. The highest methane production rates were achieved for flame manure and quinoa straw at an RSI of 1:2, with significant increases compared to an RSI of 1:1. The modified Gompertz model proved to be the best fit for performance analysis, with a constant difference of 7.06% between experimental and predicted values.

Summary: Anaerobic co-digestion is an important technology for processing organic waste, recovering nutrients, and creating sustainable biofuel. However, the low biogas output and high installation costs limit its viability. This literature review demonstrates that anaerobic co-digestion produces more methane biogas than anaerobic digestion, and adjusting the waste-to-water waste ratio can increase methane production.

Summary: This study investigated the performance and hidden hydrogen consuming metabolic pathways of a fermentative side stream dynamic membrane (DM) bioreactor using flux balance analysis (FBA). The increase in organic loading rate led to an increase in H-2 yield, while homoacetogenesis was identified as the main H-2-consuming pathway at lower OLRs. Caproic acid production pathway was identified as another significant H-2-consuming pathway at high OLR which was not significant at lower OLRs.

Summary: This study evaluated the cooking quality and texture of pasta supplemented with defatted silkworm powder or its aqueous protein extract. The results showed that silkworm powder addition increased the cooking time and water absorption rate of the pasta, while the addition of protein extract led to a more fragile structure and higher cooking loss. The study suggests that silkworm pupae flour can be easily applied for pasta fortification to increase the protein intake in a practical way.
