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: A 3%La-10%Co/Al2O3 catalyst was synthesized and optimized for ethylene glycol dry reforming (EGDR) using response surface methodology (RSM). The catalyst exhibited excellent performance in EGDR, with optimal values achieved under moderate reaction conditions (998 K, CO2 partial pressure of 15 kPa, and EG partial pressure of 23 kPa). The RSM model was statistically significant, and validation experiments showed good agreement between experimental and predicted values, confirming the validity and reliability of the model. Stability and regeneration studies further demonstrated the feasibility and catalytic stability of the 3%La-10%Co/Al2O3 catalyst.

Summary: This study optimized the production of powdered activated carbon (DPAC) from durian peels using response surface methodology (RSM). It found that an activation temperature of 900 degrees C, activation time of 30 min, CO2 flow rate of 0.05 L/min, irradiation dose of 100 kGy, contact time of 35 min, and adsorption dosage of 0.75 g resulted in an optimal removal efficiency of 97.25% for phenol. The DPAC also exhibited a BET surface area of 281.33 m²/g. The effectiveness of DPAC was compared to a commercially available activated carbon, showing 98.56% phenol removal. This study highlights the potential of durian peel as a precursor for phenol removal and the enhancing effect of irradiation on surface activation.

Summary: Hydrogen (H2) is a potential energy carrier and feedstock for decarbonization, transportation, and chemical sectors, with the potential to reduce the effects of global warming. The current leading method for H2 production is steam methane reforming (SMR), although there is still room for improvement in terms of process intensification, energy optimization, and environmental concerns. Reactors using metallic membranes (MRs) can address these issues by operating at lower pressures and temperatures, resulting in potentially lower costs. Furthermore, metallic membranes, particularly Pd and its alloys, enable the production of highly pure H2 streams. This article discusses various methods of H2 production based on different energy sources, such as SMR with CO2 capture and storage (CCUS), methane pyrolysis, and water electrolysis. The importance of green H2 generation as a future affordable alternative and the role of nanomaterials in H2 synthesis and storage are also highlighted.

Summary: This study explored the catalytic glycolysis of waste PET plastic using metal oxide catalysts supported on alumina. The basicity of the catalyst was found to be correlated with the glycolysis performances. Among the catalysts tested, 10%Ce/Al2O3 exhibited the highest conversion of waste PET with the highest selectivity to the main product BHET. The catalytic activity remained stable after five consecutive runs, and the quality of the monomer product BHET was confirmed to be excellent. This work contributes to the development of efficient heterogeneous catalysts for PET recycling technology.

Summary: Due to its simple process, environmental friendliness, and low operating costs, biometallurgy has become a popular technology for metals recovering from low-grade ores and tailings. An optimized agar was used to isolate and grow functional bacteria, resulting in the successful isolation of six functional stains. These strains were further tested for their ability to leach metals from polymetallic sulfide tailings, with significant improvements observed when the strains were mixed together. The selection of leaching process should be based on tailings composition and target metals.
