“…The study discovered that 10% sand substitution with ash yielded a 16% increment in compressive strength compared to the control concrete, with a value of 39.45 MPa. Moreover, the study showed that a high percentage of oil palm ash mixed with the concrete gave better performance on its compressive strength [ 25 ]. Numerous research studies have been completed on the utilisation of palm oil biomass waste, especially to incorporate various types of geopolymer into the composites of industrial building materials, including concrete and bricks.…”

This study aims to develop suitable formulations of geopolymer concrete (GPC) by varying the percentages of the geopolymer with aggregates and evaluating the performances in thermal and mechanical properties of palm kernel shell ash (PKSA)-GPC compared to rice husk ash (RHA)-GPC and ordinary Portland cement concrete (OPCC). Preliminary tests were conducted to select the best mix design ratios before casting the specimens. Then, the performance of the PKSA-GPC, RHA-GPC and OPCC specimens was evaluated based on their thermal performance and drying shrinkage. The mix designs of PKSA-GPC 70:30, PKSA-GPC 60:40, PKSA-GPC 50:50 and PKSA-GPC 66.6:33.3 were found to produce an acceptable consistency, rheological and thixotropic behaviour for the development of the GPC. PKSA-GPC showed a better thermal performance than the RHA-GPC and OPCC due to their strong and dense intumescent layers and slow temperature increment upon exposure to a high flame temperature from ambient temperature to 169 °C. The low molar ratio of the Si/Al present in the PKSA-GPC created a thermally stable intumescent layer. In the drying shrinkage test, PKSA-GPC 60:40 and RHA-GPC 60:40 shared an equal drying shrinkage performance (5.040%) compared to the OPCC (8.996%). It was observed that microcrack formation could significantly contribute to the high shrinkage in the PKSA-GPC 50:50 and RHA-GPC 70:30 specimens. The findings of this study show that PKSA could be incorporated into GPC as a fire-retardant material due to its capability of prolonging the spread of fire upon ignition and acting as an alternative to the conventional OPCC.

“…Moreover, the boiler incineration process has raised environmental concerns due to the release of flue gases containing ash, CO, and NO 2 into the atmosphere [ 3 ]. The oil palm ash with the light greyish colour is the waste often obtained from palm oil extraction and dumped behind the mill as unutilized left-over [ 4 ].…”

“…Many studies have evaluated the usefulness of oil palm ashes due to the high concentration of various oil palm oil elements. Previous studies have shown the possibility of using OPB as a bio-absorbent material [ 8 ], bleaching absorbent [ 2 ], partial sand replacement in concrete [ 4 , 9 ], nano-engineered wood-based panel [ 10 ], nanoparticles reinforcement materials [ 11 , 12 ], and as an adsorbent material for the removal of toxic element in contaminated water [ 13 , 14 ]. Although various oil palm ash applications have been explored, a significant quantity of OPA is still disposed to landfills, requiring a lot of land area and resulting in a huge pile of solid wastes [ 8 , 15 ].…”

The effect of incorporating different loadings of oil palm bio-ash nanoparticles from agriculture waste on the properties of phenol-formaldehyde resin was investigated in this study. The bio-ash filler was used to enhance the performance of phenol-formaldehyde nanocomposites. Phenol-formaldehyde resin filled with oil palm bio-ash nanoparticles was prepared via the in-situ polymerization process to produce nanocomposites. The transmission electron microscope and particle size analyzer result revealed that oil palm bio-ash nanoparticles had a spherical geometry of 90 nm. Furthermore, X-ray diffraction results confirmed the formation of crystalline structure in oil palm bio-ash nanoparticles and phenol-formaldehyde nanocomposites. The thermogravimetric analysis indicated that the presence of oil palm bio-ash nanoparticles enhanced the thermal stability of the nanocomposites. The presence of oil palm bio-ash nanoparticles with 1% loading in phenol-formaldehyde resin enhanced the internal bonding strength of plywood composites. The scanning electron microscope image revealed that phenol-formaldehyde nanocomposites morphology had better uniform distribution and dispersion with 1% oil palm bio-ash nanoparticle loading than other phenol-formaldehyde nanocomposites produced. The nanocomposite has potential use in the development of particle and panel board for industrial applications.

The processing of palm oil from the fruits of the African oil palm generates an increasing amounts of solid waste. The production of beneficial products for various applications from the oil palm wastes would reduce the amount of unwanted materials produced and contribute to a healthier environment. In this research, fractions were derived from the filtrate of the oil palm deseeded fruit head ash by fractional crystallization. Their physicochemical properties, cation, and anion compositions were determined by standard methods. Three hygroscopic oil palm ash fractions, namely crystals, anhydrous, and sediment, were obtained from the filtrate of the soaked ash. The crystals fraction showed significantly higher mean values than the anhydrous and sediment in conductivity and total organic matter (p<0.0001 each), salinity (p<0.01 and p<0.0001), and total organic carbon (p<0.01), while anhydrous had higher total dissolved solids than the crystals (p<0.01) and sediments (p<0.05). pH and melting points for the crystals and anhydrous compounds were similar (11.07 and <330) and higher than that of the sediment (10.29 and 284.2). Compared to the crystals, anhydrous fractions reveal significantly lower values in iron, phosphate (p<0.01 individually), zinc, chloride, nitrate, and sulphate (p<0.05 each), while sediments had significantly higher zinc (p<0.05) and nitrate (p<0.0001) and lower iron, chloride (p<0.05 each), sulphate and phosphate (p<0.0001 respectively) mean values. From this study, the isolation of three fractions from the oil palm empty fruit bunch ash with different physicochemical properties and ionic compositions was achieved. These fractions may serve as useful resources for utilization in various fields of research and production processes.
