Summary: This study utilizes rice husk ash as a low-cost alternative silica precursor for catalyst synthesis and compares it with HZSM-5. The results showed that CRHA and HZSM-5 had similar volatilized matter yield, while NiCRHA produced the highest amount. Kinetic analysis revealed that the catalytic runs followed anti-Jander diffusion. Despite having the highest activation energy, NiCRHA also had the highest pre-exponential factor, allowing it to overcome the energy barrier and produce the most volatilized matter.

Summary: The study focused on preparing hydrolysate from OPEFB through hydrothermal treatment, with hemicellulose yield decreasing from 153 mg/g-OPEFB to 27.5 mg/g-OPEFB as the temperature increased from 180 to 200 degrees C. The highest glucose yield was obtained from the enzyme-treated solid phase after hydrothermal treatment at 200 degrees C.

Summary: In this study, oil palm empty fruit bunch (EFB) was subjected to microwave-induced fast pyrolysis, and it was found that the addition of activated carbon as a microwave susceptor significantly increased the bio-oil yield, resulting in bio-oil enriched with phenolic compounds. This promising method shows potential for producing highly selective mono-phenol rich bio-oil from biowaste.

Summary: This research investigates the production of biogas and the circular economy perspective in the palm oil industry through the codigestion of oil palm empty fruit bunch (EFB) pressing wastewater and palm oil mill effluent (POME). The optimal condition for fermentation was found to be 45% POME + 50% seed + 5% EFB wastewater. The study also reveals that the sludge produced from the digester complies with the organic compost standard and can be used to nourish the soil.

Summary: This study presents a simultaneous simulation of a comprehensive pyrolysis process, bio-oil upgrading, and electric power generation using empty palm fruit bunches (PEFB) as feedstock. The results show that implementing a heat exchanger network (HEN) design can reduce costs and improve heat recovery. Economic analysis demonstrates that HEN implementation leads to higher net present value, internal rate of return, and payback duration.

Summary: Pyrolysis oil was produced and upgraded through the co-pyrolysis of treated palm oil empty fruit bunch (PO-EFB) and low-density polyethylene (LDPE) plastic waste, using calcium oxide (CaO) catalyst. LDPE plastic addition increased both the yield and quality of the pyrolysis oil. Increasing co-pyrolysis temperature decreased the yield but improved the quality of the pyrolysis oil.

Summary: In this study, empty fruit bunch oil palm was converted into biochar and used for the adsorptive removal of manganese from water. Results showed that the biochar produced at 350 degrees Celsius had the highest adsorption capacity for manganese. The study demonstrated the potential of low-cost and environmentally friendly biochar for the remediation of manganese ions in water.

Summary: There is growing interest in the use of biomass waste for bio-based products, and Nigeria, with its abundant palm biomass, presents a potential source for such products. This study focused on extracting and characterizing silica from the ash of empty palm fruit bunches. The results indicate that the ash contains a significant amount of biogenic silica in its amorphous form. The extracted silica shows potential as a catalyst support, for the development of zeolite-based catalysts, and as an adsorbent.

Summary: The co-pyrolysis of palm empty fruit bunch and waste tire using activated carbon as a carbonaceous microwave susceptor was studied. The position of the susceptor was found to have an impact on heating rates, pyrolytic oil yield, and chemical selectivity. The study showed that a susceptor located at the bottom of the feedstock produced the highest heating rate and the fewest hotspots, resulting in a higher pyrolytic oil yield.

Summary: Concerns about global warming and energy demand have driven the interest in and action to produce biodiesel as a substitute for fossil fuels. However, the increase in biodiesel production results in the generation of glycerol waste. Utilizing and upgrading this waste can reduce waste volume and increase the market value of glycerol and the sustainability of biodiesel production. This review focuses on the carboxylation of glycerol waste to produce glycerol carbonate (GC) and discusses the impact of catalysts, dehydrating agents, solvents, and other reaction conditions on the conversion and selectivity of glycerol to GC. The use and applications of GC are also reviewed.

Summary: This study investigated the effectiveness of using Fe-based MOF or MIL-100(Fe) in conjunction with a PEDOT-modified Pt electrode for detecting the synthetic azo dye tartrazine. By modifying the electrode with two different methods, favorable lower reductive potentials, competitive sensitivities, and good repeatability and stability were achieved in all MIL-100(Fe)/PEDOT/Pt electrodes.
