Increasing the volume of palm oil production impacts the amount of waste the palm oil industry produces. This waste, if handled properly, will have a positive impact on the environment. Boiler efficiency and energy value can be increased while reducing solid waste and fossil fuel emissions by using shells and fibres as fuel. However, burning biomass as boiler fuel leaves residue as palm oil fuel ash (POFA) and is generally thrown away. POFA contains silica and can be extracted and synthesized into silica nanoparticles (Si-NPs) by process engineering. Si-NPs derived from agricultural waste or renewable sources are environmentally friendly and have unique properties such as high surface area, adjustable pore diameter, and excellent chemical and thermal stability. These properties make Si-NPs ideal for water purification, and this paper reviews recent advances in the synthesis of Si-NPs using POFA, future research directions, and challenges in the application of Si-NPs for water purification. This review compiles information from research articles on the current synthesis of environmentally friendly Si-NPs as study material to develop and utilize POFA waste as a biomaterial in fabricating filtration membranes in water purification.

“…This indicated the presence of amorphous glassy material [36]. POFA with reashing pretreatment at 600 o C for 2h showed a sharp peak at an angle of 2θ=26.7°, indicating the presence of quartz SiO2 as the main crystalline phase [36,39]. When POFA was extracted using NaOH solution to produce biosilica, its XRD diffraction pattern showed a broad peak at an angle of 2θ=21-23°, indicating that the crystalline silica had turned into an amorphous form [38].…”

Pretreatments and extraction conditions can affect the yield and characteristics of biogenic silica (biosilica) from palm oil fuel ash (POFA). This study aimed to examine how reashing pretreatment and varying NaOH concentrations influence the yield and properties of biosilica extracted from POFA by a simple sol-gel method. Re-ashing pretreatment was conducted using a furnace at a temperature of 600°C for 2h. All samples were leached using a citric acid solution. Extraction process was carried out using NaOH solutions with concentrations of 6%, 8%, and 10%). The results showed that re-ashing pretreatment and concentrations of NaOH significantly influenced (p<0.05) the extraction yield, color, crystallinity, and specific surface area of POFA-derived biosilica. Re-ashing pretreatment in combination with a 10% NaOH solution produced the highest extraction yield of biosilica (17.25% w/w) with a bright white color (L=91.83; WI=91.32), SiO2 concentration of 94.68%, crystallinity of 50.10%, and specific BET surface area of 390.80m2/g. XRD patterns confirmed the amorphous nature of POFA-derived biosilica. FTIR spectra revealed the presence of silica functional groups in all samples. This study demonstrated the important roles of re-ashing pretreatment and NaOH concentration in producing POFA-derived biosilica with better yield and properties that could broaden its potential applications.

“…The utilization of nanosilica as a reinforcement has been observed across several material domains [16][17][18][19]. The process of extracting silica from RHA was conducted by a solid-liquid extraction method, wherein an alkaline solution was employed as the solvent [20][21][22][23]. The presence of silanol groups on the surface of rice husk ash can enhance its reinforcing properties when used as a reinforcement material.…”

The topic of environmental contamination is currently regarded as one of the most urgent and significant challenges in contemporary society. Several strategies must be implemented to mitigate the environmental impact caused by waste materials, such as to rice husks ash, plastic, and other materials. Low-density polyethylene is widely recognized in academic circles for its distinctive property of having a low melting point and demonstrating inferior thermal stability. However, the utilization of RHA has promise for augmenting the thermal LDPE. The inclusion of silica inside rice husk ash functions as a flame retardant, hence augmenting the material's capacity to resist combustion and thermal degradation. The objective of this study is to utilization of eco-friendly RHA waste as reinforcement in LDPE thermoplastics. RHA is produced by the coprecipitation process. Rheomixer is used to make thermoplastic composites by incorporate RHA into LDPE 0, 2, 4, 6, 8, and 10 wt.%. The micrograph of the failure surface of the composite material consisting of LDPE filled with reactive hot-melt adhesive RHA particles reveals significant variations in particle sizes. In adittion XRD graph showed a decrease in intensity when 6% wt and 8% wt RHA were added. The results of thermal analysis with DSC showed an increase in the melting point of the sample with RHA reinforcement from 108.96-109.21 o C and 482.47-500.09 o C. The incorporation of RHA as a reinforcement in LDPE holds promise for its utilization as a material possessing favorable thermal characteristics suitable for industrial applications such as pipes and protective coatings, which required enhanced thermal resistance. The utilization of rice husk ash (RHA) waste imposes both environmental and economic impacts. RHA has the potential to reduce environmental pollution caused by waste and decrease the costs involved in material production.
