“…It is difficult to formulate treatment strategies for the contaminated site to degrade the contaminant to safe level (Mrayyan and Battikhi 2005). Incineration of contaminated oil has many disadvantages, such as high operational cost due to requirement of high energy, large space, and environmental pollution (Okoh et al 2019). Alternatively, composting of the polluted soil can be carried out.…”

Thousands of oil spill incidents regrettably have occurred on a daily basis around the globe. Oil spills are a form of pollution that poses major catastrophic threats to marine ecosystems. Oil spill incidents commonly occur in the middle of the ocean, and the process to remove the oil becomes a great challenge. Absorbents, due to their good oil-absorbing characteristics, are becoming more popular nowadays as one of the effective oil spill clean-up methods. Among the many types of oil absorbents, plant fibers were also being studied to remove the oil spills from the sea surface. This paper reviews factors leading to oil spills, the detrimental effect of the oil spill on the environment, the oil spill removal methods, and the application of plant fibers as oil absorbent material. The paper also will highlight the latest development on the utilization of kenaf core fibers as oil-absorbent material and the use of oil absorbed kenaf core fibers as fuel briquette by taking advantage the high calorific value of the oil spill.

“…This critical review discusses the latest advances and problems in using bioremediation for oil spills and examines the potential of utilizing nanoscience to enhance bioremediation efforts for future oil spills. Currently reviews on oil spill cleanup focus primarily on one method, such as bioremediation − or the utilization of nanomaterials. , This review is the first to offer a critical analysis of the use of nanomaterials for the purpose of enhancing bioremediation. We call this new interdisciplinary area of research nano-enhanced bioremediation .…”

Nano-enhanced Bioremediation for Oil Spills: A Review

Oil seepage and spills have lasting detrimental effects on the environment, especially on nearby marine ecosystems. Despite quick and safe removal of contaminating oil being of utmost importance, remediation methods have remained largely unchanged over the last 20+ years. Removal methods such as skimmers, in situ burning, and sorbents can be difficult to implement in inclement weather. Marine microorganisms consume spilled oil as a primary energy source in a method known as bioremediation. Recently the introduction of nanoparticles to areas contaminated by oil has emerged as a potential method to enhance the efficacy of oil degradation by marine microorganisms. Nanoparticles have been primarily utilized as magnetic sorbents but can also act as emulsifiers, increasing the bioavailability of the oil by giving microbes a surface (droplets) to which they can attach and facilitate proliferation. Emulsification increases the oil−water interfacial area and often leads to an increase in the amount of oil degraded by microorganisms. Nanoenhanced bioremediation is effective on a variety of oil compositions and is minimally impacted by weather. It offers a sustainable alternative to traditional remediation methods, i.e., chemical dispersants, sorbents, and in situ burning, which are often toxic and ineffective.

We studied the long-term dynamics of plant communities after bio and phytoremediation of oil-polluted soils. Nine plots located in European Northeast and treated using various bioremediation methods were monitored from 2002 to 2014. Geobotanical descriptions (relevés) of each plot were performed in 2006 and 2014, and Grime’s theoretical CSR (competition–stress–ruderality) framework was used to assess the vegetation state and dynamics. We observed a clear shift of communities from pioneer (where ruderal species were prevalent) to stable (where competitor species were dominant) states. However, the remediation type did not significantly impact the vegetation recovery rate. After 12 years, all methods led to a 55–90% decrease in the oil content of the soil and a recovery of the vegetation cover. The plant communities contained mainly cereals and sedges which significantly differed from the original tundra communities before the oil spill. The control plot, treated only by mechanical cleaning, had minimum oil degradation rate (50%) and vegetation recovery rates, although, in CSR terms, its vegetation assemblage resembled the background community. Cereals (Agrostis gigantea, Deschampsia cespitosa, Phalaris arundinacea, and Poa pratensis), sedges (Carex canescens, Carex limosa, and Eriophorum vaginatum), and shrubs (Salix) were found to be the most effective species for phytoremediation, exhibiting high community productivity under the harsh northern conditions.
