Article Synopsis
- The research evaluates the commercial potential and economic viability of biomass gasification using an established downdraft gasifier model, focusing on the influence of key factors like temperature and equivalence ratio on syngas properties.
- Among the feedstocks tested, coconut shell proved to be the most effective, producing syngas with high low heating value (LHV) and cold gas efficiency (CGE) at optimal temperatures.
- Larger-scale operations, particularly a 20 MW plant, exhibited positive economic indicators such as a short payback period and lower electricity costs, highlighting the potential for biomass gasification to be a sustainable option for power generation.

Water is an indispensable resource for human activity and the environment. Industrial activities generate vast quantities of wastewater that may be heavily polluted or contain toxic contaminants, posing environmental and public health challenges. Different industries generate wastewater with widely varying characteristics, such as the quantity generated, concentration, and pollutant type.

Article Synopsis
- Researchers developed a high-entropy (NiFeCoV)S porous nanosheet catalyst to enhance hydrogen production from seawater by improving efficiency in the oxygen evolution reaction (OER) while minimizing side reactions like chloride evolution.
- The catalyst features a rough and porous design that increases active surface area and active sites, leading to better mass transfer and catalytic performance with low overpotentials of 220 and 299 mV in alkaline water and seawater, respectively.
- Additionally, it demonstrates long-term stability, resisting degradation for over 50 hours and enabling efficient water splitting with voltage requirements of only 1.69 V and 1.77 V for alkaline water and seawater, signaling potential for practical applications.
The rising pressure on both cleaner production and sustainable development have been the main driving force that pushes mankind to seek for alternative greener and sustainable feedstocks for chemical and energy production. The biomass 'waste-to-wealth' concept which convert low value biomass into value-added products which contain high economic potential, have attracted the attentions from both academicians and industry players. With a tropical climate, Malaysia has a rich agricultural sector and dense tropical rainforest, giving rise to abundance of biomass which most of them are underutilized.

The exergy analysis of each heat exchanger presented an efficient heat coupling between hot and cold streams, thus minimizing the total exergy destruction. Simulation results showed that the unit production cost of optimized process is 0.
