An advancement was achieved through orthogonal optimization (L9(34) design) of exogenous hydrogen supplementation, identifying 60 mL H2 injection for 13 min thrice daily as optimal parameters.

However, significant challenges remain regarding their efficiency, scalability, and integration into practical applications. This study addresses these gaps by evaluating the electrochemical performance of an Aloe vera-based P-MFC compared to a control microbial fuel cell (MFC) consisting solely of potting soil and graphite electrodes. Electrochemical analyses, including open-circuit voltage (OCV), linear sweep voltammetry (LSV), and electrochemical impedance spectroscopy (EIS), were conducted to assess system performance. The Aloe vera-based P-MFC demonstrated a stable OCV approximately 27 mV higher, a current density 3.7 times greater, and an impedance nearly 4.7 times lower than the control MFC. Additionally, the peak power density of the Aloe vera-based P-MFC reached 1100 mW/m2, significantly outperforming the control MFC, which yielded 250 mW/m2. The superior performance of the Aloe vera-based P-MFC is attributed to the plant’s photosynthetic activity, which enhances microbial interactions and electron transfer efficiency. Notably, the successful series connection of Aloe vera-based P-MFCs facilitated the charging of a lead-acid battery, which was subsequently used to power an LED, demonstrating the system’s practical applicability. This study contributes to the advancement of P-MFC technology by highlighting Aloe vera’s potential as an efficient bioelectricity generator.

This organic matter may be present in urban, industrial, and agricultural residues. The integration of these resources into co-digestion systems can increase methane productivity by optimizing the nutrient balance for AD. Therefore, identifying potential substrates for AD is crucial for optimizing and managing this process. This study aimed to use cattle manure (CM) and blood water (BW) as potential co-substrates for co-digestion with sugarcane vinasse (V) by assessing the biochemical methane potential (BMP) of mono- and co-digestion systems. Kinetic adjustment was conducted to understand the dynamics of the system, and the energy potential was estimated based on the lower heating value of methane. The BMP of V mono-digestion reached 49.67 NmLCH4 g−1VS, whereas that of CM reached 119.93 NmLCH4 g−1VS. For co-digestion systems, the mixture V-67 + BW-33 (67% of the mixture are composed of V and 33% of the mixture are composed of BW; volume by volume—v/v) reached the highest BMP of 369.47 NmLCH4 g−1VS, representing an increase of 87%, in relation to the V mono-digestion. For the tests with the three substrates, the best condition in terms of methane production was in the proportion V-16.5 + CM-67 + BW-16.5 (245.13 NmLCH4 g−1VS), resulting in an increase of 80% and 51% in comparison to the mono-digestion of V and CM, respectively.

CLG of solid wastes has gained attention for its satisfactory performance with waste valorization. The chemical looping co-gasification (CLCG) performances of rice husk and textile wastes are investigated, which are typical solid wastes used in industry as alternative fuels. A thermodynamic process model of CLCG is established, and the effects of different operating parameters are quantitatively analyzed. Furthermore, a multi-input and multi-output back propagation neural network model (BPNNM) is trained using process model results for the performance prediction. Key findings reveal that increasing equivalence ratios of oxygen carrier and steam (αOC/F and αsteam/F) significantly affect gasification efficiency. Specifically, increasing αOC/F to 0.5 decreases gasification efficiency to 60.82%. Conversely, increasing αsteam/F from 0.1 to 0.5 leads to a slight decrease in gasification efficiency from 85.95 to 84.80%, while simultaneously increasing hydrogen concentration in syngas from 39.91 to 46.28%. Elevating the gasification temperature from 650 to 850 °C can raise the η from 81.52% up to 86.00%. The blending ratio of the rice husk and textile waste also dramatically affects gasification efficiency, with efficiency decreasing from 92.27 to 74.41% as the blending ratio Rr increases from 0 to 1.
