Summary: A comparative study was conducted to investigate the effects of various parameters on power generation in an aerobic microbial fuel cell using cow manure-pretreated slurry and sewage sludge. The optimal conditions for maximum power production were determined to be an electrode depth of 7 cm, a pH of 6, and a feed ratio of 2:1 in the CM + SS system. Response surface methodology was applied to establish the relationship between the parameters and the response. The results showed that an ON/OFF controller was effective in maintaining stable power output.

Summary: The yield of bio-methane and bio-hydrogen was enhanced by co-digesting banana plant waste (BPW) and sewage sludge (SS). Acclimatisation of the inoculum SS was performed in a continuous stirred tank reactor (CSTR), and its various parameters were analyzed daily. Six different BPW to SS ratios were optimized and incubated in a manual methane potential test setup (MMPTS) for 40 days, with R4 (60% BPW and 40% SS) showing the highest yields. Furthermore, the best achieved ratio of BPW and SS was treated with different doses of NaOH as an alkaline pre-treatment, and the highest bio-methane yield was observed with dose 2 (0.75 mol NaOH) at 620.8 NmL/day. The study demonstrates the promising potential of co-digestion of BPW and SS for enhanced bio-methane and bio-hydrogen production.

Summary: Researchers are working on utilizing various kinds of organic wastes through the process of anaerobic digestion to produce valuable energy sources. They have developed a portable anaerobic digester that is mixed with a membrane electrode assembly to produce enriched biogas and electricity. The analysis shows that the methane concentration in the biogas increases when the digester is mixed with the membrane electrode assembly. Introducing a conductive surface in the anaerobic chamber of the digester helps promote methane enrichment. Additionally, the hybridized digester is capable of producing a certain voltage and power density.

Summary: Ex-situ biomethanation in a biotrickling filter is a technology that converts CO2 to CH4 using hydrogenotrophic methanogens in a biofilm. Nutrient supply, particularly ammonium and iron, is crucial for maintaining an active biofilm. Thoroughly wetting the biofilm with nutrient media periodically is essential for stable operation, despite temporary reductions in conversion rates.

Summary: This work discusses the concept of a co-production system that uses a blend of lean methane and biogas to generate electricity and improve the efficiency of coal mine methane utilization. By adding biogas generated from straw around the mines to the lean methane flow, the desired gas concentration can be achieved for power generation. The study shows that the co-production system significantly improves the utilization efficiency of lean methane in coal mines and reduces greenhouse gas emissions. The system has significant economic and environmental benefits, and has potential for widespread adoption.
