“…Less availability of space compound at high packing density (0.11 g/cm 3 ) to adsorb oil is the main reason for the decrease in oil absorbed efficiency [48]. Similar observations have been reported previously by Verasoundarapandian et al [7], Taufik et al [11], Khalid et al [39] and Abel et al [49]. In addition, the development of porosity between the fibre was increased in a lower fibre packing density (0.06 and 0.07 g/cm 3 ) due to non-compacted samples having no sufficient capillary pressure to absorb oil [39,50].…”

“…To reinforce the weak surface properties and improve the interface of the fibre matrix, a thermal treatment modification that reduces the polar components was used [38]. Previous research has proven that the absorbent efficiency increases in heat-treated samples [7,11,[39][40][41][42]. Thermal treatment, which leads to the modification of the fibre surface, supports a more significant fibre interaction by successfully decreasing the water absorption [43,44].…”

“…Agricultural waste as a biosorbent is promising as it produces no secondary pollution and has no negative effects on the ecosystem. The lignocellulosic sorbent materials that are proven to have good results in removing oil pollution include cotton [9], palm fibres [10], rice straw [11] and fruit peels [7]. The current procedures for cleaning up an oil spill are to use absorbent booms with a blend of synthetic and natural sorbent materials [12].…”

Agricultural sorbents have received attention for their effectiveness in oil removal. In Malaysia, oil palm’s empty fruit bunch (EFB) spikelets are an abundant agricultural waste that provides a non-toxic, renewable resource of cellulosic materials. In this study, the effectiveness of EFB spikelets to remove oil spills from seawater pollution in a filter system was investigated and the best optimisation approach for filtering conditions was determined. Experiments for oil spill clean-up were performed using a filter-based oil sorption system with a series of conditions such as temperature, time, packing density, and oil concentration to evaluate sorption capacity, oil and water absorbed efficiency. Fourier transform infrared spectroscopy (FTIR) was used to characterise the physicochemical properties of untreated and treated EFB fibres. Based on one-factor-at -a-time (OFAT) analysis conducted at 160 °C for 30 min on 0.1 g/cm3 of packing density containing 25% diesel, 8.667 mL of oil and 5 mL of water was absorbed. In response surface methodology (RSM), the three parameters of temperature, packing density and diesel concentration were observed as significant. From RSM fitting model analysis, the predicted value obtained for both oil and water absorbed were 8.805 and 5.213 mL, respectively. The experimental RSM values of 9 and 5 mL of oil and water absorbed were obtained. The result demonstrated the validity of the model as the experimental RSM values were close to the RSM model’s prediction. As compared to OFAT, the RSM method is more efficient in oil removal. This research contributes to a better knowledge of the usage of a natural sorbent as a method of diesel pollution remediation.

The present study was conducted to evaluate the effectiveness of paddy straw and wheat chaff filter socks for removing suspended sediments from canal water and stormwater runoff. The filter socks of three different diameters of 15, 22.5 and 30 cm; three densities classified as low, medium and high and fixed length of 120 cm were prepared. The flow rate per unit depth of water of filter socks varied between 0.07-0.08 lps/unit head. The total suspended solids removal efficiency of filter socks was up to 65%. There was a little impact on other quality parameters of TDS, pH, EC, BOD, COD and E. coli as these values remained relatively unchanged between inlet and outlet samples. The life of filter socks ranged between 44-56 hours in case of an inlet water TSS load of less than 300 ppm, which drastically reduced to less than 14 hours when the inlet water TSS load increased beyond 700 ppm. Based on the findings, it was recommended that paddy straw filter sock of 30 cm diameter, with medium to high density range of 55.81 to 69.76 kg/m 3 , can be effectively used for reducing the suspended load from runoff. Overall, the study suggests that filter socks made from agricultural waste materials such as paddy straw and wheat chaff can be a viable and sustainable stormwater management technique. They offer low-cost alternative to traditional stormwater management practices and have the added benefit of utilizing agricultural waste that would otherwise go to waste.

“…The application of natural adsorbents from agricultural wastes with good oil sorption capacity is very suitable and applicable. 11,12 For example, modified cellulose fiber, 13 rice husk, 14 rice straw, 15 raw cotton, 16 palm leaves and palm endocarp (shell), 17 kapok, 18 sugarcane bagasse 19 sawdust and sponge-gourd 20 have been investigated as oil sorbent. These biomass sorbents have several advantages such as biodegradability, economy, technical feasibility, and environmental acceptability for cleanup of oil spill.…”
