Purpose The most widely recycled plastic in the world is recycled polyethylene terephthalate (rPET). To minimize the environmental related issues associated with synthetic fibers, several researchers have explored the potential use of recycled polyester fibers in developing various technical textile products. This study aims to develop needle-punched nonwoven fabrics from recycled polyester fibers and investigate its suitability in oil spill cleanup process. Design/methodology/approach According to Box and Behnken factorial design, 15 different needle-punched nonwoven fabrics from recycled polyester fibers were prepared by changing the parameters, namely, needle punch density, needle penetration depth and fabric areal weight. Several featured parameters such as oil sorption, oil retention, oil sorption kinetics, wettability and reusability performance were systematically elucidated. Findings The maximum oil sorption of recycled nonwoven polyester is found to be 24.85 g/g and 20.58 g/g for crude oil and vegetable oil, respectively. The oil retention is about 93%–96% in case of crude oil, whereas 87%–91% in case of vegetable oil. Recycled polyester nonwoven possesses good hydrophobic–oleophilic properties with static contact angle of 138° against water, whereas 0° against crude oil and vegetable oil. The reusability test results indicate that recycled polyester nonwoven fabric can be used several times because of its reusability features. Originality/value There is no detailed study on the oil sorption features of needle-punched nonwoven fabrics developed from recycled polyester fibers. This study is expected to help in developing fabrics for oil spill cleanups.

Biosorbents have been highlighted as an alternative method for the removal of contaminants from spills or leaks of oil and its derivatives, since they are biodegradable, are highly available, low-cost, and have a good sorption capacity. This research investigated the sorption capacity of Calotropis procera fiber in natura (CP) and thermally treated (150 °C and 200 °C) for crude oil removal and recovery. The oil sorption tests were carried out in a dry and water (layer) static systems. The assays revealed that CP fiber has excellent hydrophobic-oil properties and good crude oil sorption capacity, about 75 times its own weight (76.32 g/g). The results of the treated fibers, CPT150 and CPT200, showed oil sorption capacities (in 24 h) higher than CP, between 94.31–103.37 g/g and 124.60–180.95 g/g, respectively. The results from sample CPT200 showed that it can be an excellent biosorbent for the removal of crude oil and other derivatives due to its high hydrophobicity, great reuse/resorption capacity, and ability to retain oil within the fiber lumens. Thus, it can be applied in the recovery, cleaning, and removal of petroleum products and its derivatives from spills and leaks in the future.

Oil spill accident occur due to human carelessness and error during oil transportation, storage, and production of the hydrocarbon. Effect of oil spill can be either short or long term. It is not only affecting the environment but also marine life, economy, and social. Thus, effective recovery and control method must be carefully implemented to minimise the effect. There are various studies and technologies to mitigate the oil spill incident but mostly the techniques are very expensive, difficult and use of non-environmental friendly material. Hence, this study is conducted to study areca nut husk as a potential oil adsorbent for oil spill recovery. The characteristics of areca nut husk include morphological structures and chemical composition. The areca nut husk oil sorption effectiveness and capacity also been investigated. Areca nut husk were tested for both heavy crude oil and diesel adsorption. The result shows that the efficiency of oil sorption of areca nut husk toward heavy crude oil is 14.8% and it can be an alternative sorbent material to the current modern material. Meanwhile, the areca nut husk is not recommended to be used for diesel absorption activity for its low effectiveness (i.e., 2.04%) showed in this study.

This study will present a novel method for crude oil remediation in water. The research was carried out to explore the possible application of Sterculia setigera as a potential biodegradable sorbent for oil cleanup from water. The crude Sterculia setigera (CSS), retted Sterculia setigera (RSS) and bleached Sterculia setigera (PFSS) were subjected to sorption studies to optimize their sorption capacity. The results revealed that the efficiency of sorbent to remove crude oil from water is related to the sorbent weight, contact time, initial oil concentration and temperature of sorption. It was found that increase in sorbent weight led to increase in sorption capacity from 3.75 -5.12 g/g, 4.72- 6.41 g/g, and 4.61-6.18 g/g in CSS, RSS and PFSS respectively. Oil sorption capacity increases by 21-27% when oil concentration was varied from 5-20 g. Contact time played a role only at the beginning of oil sorption study and became less important near equilibrium. Sorption time was varied from 10-70 min and the highest sorption capacity was recorded at 30 min. then it gradually reduced and became steady. The effect of temperature was investigated from 30-60°C. A decreased of 34-37% in oil sorption capacity was observed with increased in temperature.  RSS exhibit lower water sorption when compared to the other sorbents. The sorbents showed good reusability after 8 cycles, with less than 50% reduction in sorption capacity and good reusability. Sterculia setigera demonstrated good potentials for utilization as natural sorbent for oil cleanup.

Crude Oil Spill

Abstract Oil spill remediation has continued to be a challenge in the world today. Thus efforts are still been made to develop more efficient oil spill mop up techniques. Natural adsorption with agricultural wastes, which otherwise constitute environmental pollution, has become an attractive technique for oil spill mop. Acetylation using acetic anhydride with iodine catalyst was carried out to improve the hydrophobicity of African oil bean seed pod (AOBSP), which is a lignocellulosic material and as such is naturally hydrophilic. Characterization of the raw and acetylated AOBSP were done using SEM, BET and FTIR analyses. Batch crude oil sorption tests were performed using both the raw and acetylated AOBSP. Isotherm, kinetic and thermodynamic studies were also carried out. FTIR analysis showed evidence of successful acetylation of AOBSP and adsorption of crude oil onto the raw and acetylated AOBSP. SEM and BET analyses showed improvement of the surface properties of AOBSP by the acetylation process. The BET surface area increased from 226.4 m2/g for the raw AOBSP to 310.0 m2/g for the acetylated AOBSP. Oil sorption was found to be by monolayer coverage, with monolayer sorption capacity of 5000mg/g and 12500mg/g for raw and acetylated AOBSP, respectively. The rate-controlling mechanism for the sorption processes was chemisorption. Negative values of ΔGo, ΔHo and ΔSo were obtained, showing that the sorption processes were feasible, spontaneous and exothermic, with a degree of orderliness at the solid–mixture interface. The results obtained from this study show that both raw and acetylated AOBSP are efficient oil sorbents with potentials for further improvement for oil spill mop.

Expanded graphite was used for absorbing methyl orange in water and crude oil floated on water. The effect of agitating sorption system including crude oil or methyl orange, water and expanded graphite on the sorption behavior of expanded graphite for the two materials was investigated, and the sorption mechanism of expanded graphite for the two materials was discussed. The results show that agitating sorption system is advantageous for the methyl orange sorption, but disadvantageous for the crude oil sorption.
