Biogas and biomethane production 2
Enhancing Biogas Production through Synergistic Effects of Conductive Materials in Two-Stage Fermentation Processes
Short Introductive summary
Although previous studies have highlighted the positive impacts of individual conductive materials (CMs) on biological processes, there has been a gap in research regarding the synergistic effects of combining multiple CMs in a two-stage fermentation process (TSFP) for the production of hydrogen (H2) and methane (CH4). Furthermore, the specific functions of different CMs in such anaerobic environments have not been clearly defined. This research found that introducing a combination of two or more CMs as biocatalysts in the processing of food waste through TSFP significantly boosts biogas generation compared to the use of a solitary CM. This investigation also detailed the unique contributions of various CMs towards the production of H2 and CH4 within the TSFP. Specifically, magnetite nanoparticles (MNP) were identified as key enhancers of H2 production and overall energy yield, whereas powdered activated carbon (PAC) was most effective in increasing CH4 production efficiency and enhancing chemical oxygen demand (COD) removal. These insights are particularly valuable as they provide an initial understanding of the individual roles played by different CMs.
