Oil pollution such as diesel poses a significant threat to the environment. Due to this, there is increasing interest in using natural materials mainly from agricultural waste as organic oil spill sorbents. Oil palm’s empty fruit bunch (EFB), a cost-effective material, non-toxic, renewable resource, and abundantly available in Malaysia, contains cellulosic materials that have been proven to show a good result in pollution treatment. This study evaluated the optimum screening part of EFB that efficiently absorbs oil and the physicochemical characterisation of untreated and treated EFB fibre using Fourier Transform Infrared Spectroscopy (FTIR) and Scanning Electron Microscopy (SEM). The treatment conditions were optimised using one-factor-at-a-time (OFAT), which identified optimal treatment conditions of 170 °C, 20 min, 0.1 g/cm3, and 10% diesel, resulting in 23 mL of oil absorbed. The predicted model was highly significant in statistical Response Surface Methodology (RSM) and confirmed that all the parameters (temperature, time, packing density, and diesel concentration) significantly influenced the oil absorbed. The predicted values in RSM were 175 °C, 22.5 min, 0.095 g/cm3, and 10%, which resulted in 24 mL of oil absorbed. Using the experimental values generated by RSM, 175 °C, 22.5 min, 0.095 g/cm3, and 10%, the highest oil absorption achieved was 24.33 mL. This study provides further evidence, as the data suggested that RSM provided a better approach to obtain a high efficiency of oil absorbed.

Abstract Background: The frequency of crude oil pollution has been on the increase following increased exploration, exploitation and production of energy from fossil fuel. Bioremediation has been shown to be eco-friendly and cost-effective method of oil spill remediation. In the Niger Delta, Landfarming has been the most used technique. The aim of this research was to employ metagenomic techniques to understand microbial dynamics during field-scale remediation in the Niger Delta in order to improve and reduce the time of remediation. Results: The surface (0.0 – 0.5m) sample had an extractable TPH value of 6231 mg/kg. The subsurface samples from 1m, 1.5m and 2.0m depths had extractable TPH concentration of 4836 mg/kg, 9112 mg/kg and 7273 mk/kg respectively. Proteobacteria dominated the bacterial community of the oil-polluted soil and comprised mainly of the classes Alphaproteobacteria, Betaproteobacteria and Gammaproteobacteria. Alpha diversity analysis revealed the presence of crude oil in the soil reduced microbial diversity. Principal coordinate analysis showed the microbial structure continually changed following changes in the chemical composition of the soil. Mycobacterium, Burkholderia, Methylobacterium and Bacillus were among the core OTUs detected during the period of remediation. Significant variation in pathway abundance particularly pathways for propanoate degradation, benzoate degradation, naphthalene degradation, fatty acid metabolism, polycyclic aromatic hydrocarbon degradation and degradation of xenobiotics were observed when the unpolluted soil was compared to the samples obtained during remediation. Conclusions: The findings from this study will greatly advance an already preferred landfarming oil spill recovery technique in the Niger Delta.

Oil Spill Response

ABSTRACT The bulk liquid petroleum transportation industry is, to an increasing degree, implementing quality management programs. Shipping companies are mandated to become ISM-certified by 1998. Several oil companies are becoming ISO 9000-certified. The trend is for government to relax its detailed inspections for compliance as companies demonstrate compliance through implementation of quality systems. The oil spill response industry has evolved over the past 25 years with relatively little government regulation. Several unilateral and joint government/industry programs have been undertaken since the mid-1970s to develop various product and performance standards for the oil spill response industry. Following the passage of the Oil Pollution Act of 1990 (OPA 90), the USCG implemented the Oil Spill Removal Organization (OSRO) Classification Program in an attempt to quantify the capabilities of OSROs for potential customers. Though certainly a beginning in addressing the issue of quality, the OSRO Classification Program focuses on equipment issues. With much of the bulk liquid petroleum transportation industry actively engaged in the quality movement, the time is right for the oil spill response industry to join the ranks. A logical extension of the OSRO Classification Program is the voluntary implementation by OSROs of, and future certification to, ISO 9000/14000 quality and environmental standards. OSROs so certified could expect less government oversight in the future and would enjoy a more competitive marketing advantage. Responsible parties employing ISO-certified OSROs could expect higher quality and more cost-effective responses and perhaps more favorable insurance rates.

ABSTRACT As called for under the International Convention on Oil Pollution Preparedness, Response and Co-operation, 1990 (OPRC), “Parties to the OPRC convention are required to establish measures for dealing with pollution incidents, either nationally or in co-operation with other countries.” As a signatory to OPRC the U.S. Government (USG) has pledged to assist other countries in the development of their own oil spill response capabilities and while USG has many agreements that meet the guidelines of assisting other countries, there is no formal engagement strategy for developing further agreements, no agency championing this effort, and there are many still requiring assistance. However, the United States Coast Guard (USCG) is uniquely positioned to perform the role of drafting an engagement strategy and working with the global community to assist those countries that have yet to develop an adequate oil spill response system of their own due to the lack of resources, expertise or both. There are many hurdles to enabling USCG to assume the OPRC assistance banner that have been previously addressed (Adams, IOSC 2001), which this paper will not seek to readdress. However, if USG does decide to move forward with an integrated policy there remains the need to develop an adequate engagement strategy. This strategy is necessary to ensure the limited resources available for foreign assistance are expended in the most cost effective, ethical and responsible manner possible. There are three alternative strategies I will analyze in an effort to determine the best suited for implementation of this policy. These three strategies are based primarily on 1) environmental need, 2) geographical proximity, and 3) political/economic interests. The goal of this strategy is to effectively implement the oil spill assistance policy alluded to previously in support of the U.S.'s pledge under OPRC. This paper will analyze the success of each strategy making a recommendation on which one USG should pursue.

Extraction And Purification

In recent years, downstream bioprocessing industries are venturing into less tedious, simple, and high-efficiency separation by implementing advanced purification and extraction methods. This review discusses the separation of proteins, with the main focus on amylase as an enzyme from agricultural waste using conventional and advanced techniques of extraction and purification via a liquid biphasic system (LBS). In comparison to other methods, such as membrane extraction, precipitation, ultrasonication, and chromatography, the LBS stands out as an efficient, cost-effective, and adaptable developing method for protein recovery. The two-phase separation method can be water-soluble polymers, or polymer and salt, or alcohol and salt, which is a simpler and lower-cost method that can be used at a larger purification scale. The comparison of different approaches in LBS for amylase purification from agricultural waste is also included. Current technology has evolved from a simple LBS into microwave-assisted LBS, liquid biphasic flotation (LBF), thermoseparation (TMP), three-phase partitioning (TPP), ultrasound-assisted LBS, and electrically assisted LBS. pH, time, temperature, and concentration are some of the significant research parameters considered in the review of advanced techniques.

ABSTRACT This paper examines the costs of various cleanup techniques, drawing mainly on information from recent oil spills from ships. Analyses of the costs for dispersant application and for the use of offshore mechanical recovery equipment are compared in relation to their effectiveness and scope for reducing shoreline cleanup costs and damage from oil pollution. Spill size, oil type, coastline character, and the extent of pollution all contribute to the observed differences in shoreline cleanup and disposal costs. The influence of these factors is evaluated and criteria are proposed for selecting the most appropriate cleanup response to suit the circumstancees of a particular oil spill. On occasions, a response at sea is both necessary and worthwhile, but for most spills shoreline cleanup, including protection of sensitive resources, is likely to be the most cost-effective option.

ABSTRACT This paper evaluates the role of natural recovery in the restoration of populations, communities, and ecosystems following natural and anthropogenic disturbances, especially oil spills. Under the Oil Pollution Act of 1990, options for the restoration of natural resources and services injured by oil spills range from natural recovery to aggressive methods requiring human intervention. Natural recovery is defined herein as the return of natural resources to a dynamic baseline with no active human intervention. Populations, communities, and ecosystems are a product of biological responses to a wide variety of natural and anthropogenic disturbances. In an oil spill, biological communities will generally recover naturally to baseline conditions about as quickly and effectively as they will with active human interventions, and at a lower cost and lower commitment of people, equipment, and materials. Therefore, natural recovery should be considered a primary restoration alternative for each oil spill incident. Natural recovery should also be the standard or benchmark restoration alternative against which all active restoration alternatives are compared for cost-effectiveness and probable success in restoring natural resources and services. We conclude that natural recovery is a cost-effective, efficient process that, in most oil spills, restores natural resources to baseline about as quickly as would the most aggressive active restoration alternative.

The Relationship

ABSTRACT The natural resource damage assessment (NRDA) process under the Oil Pollution Act regulations is restoration-focused. In order to proceed with a NRDA after Preassessment Phase activities are completed, the natural resource trustees must determine that feasible restoration actions are available to address the potential injuries resulting from the discharge of oil. If this determination is made, the trustees can move forward and conduct injury assessment and injury quantification as part of the Restoration Planning Phase. The availability of appropriate restoration alternatives for natural resources can have a profound effect on the nature of both injury assessment and injury quantification that is necessary for a particular oil spill. This paper examines that relationship, using some examples from settled oil spill NRDA cases to illustrate how the availability of appropriate and cost-effective restoration alternatives can reduce the overall cost of a NRDA and the length of time necessary to reach an appropriate settlement. The type of restoration and the degree to which it is scaleable can also influence both cost and time to reach settlement. It also discusses some of the factors that are important in determining to what degree restoration opportunities influence the injury assessment and quantification process for oil spills, including geographic location, previous experience with similar spills, and the degree of cooperation that exists between the trustees and the responsible party.

Reduction of food rations and shortages is one of the impacts of the increasing human population. Food sector industries then try to cope with the fast growing number of customers. Agribusiness sector gains its popularity in these recent years, including pig farm. The increase trend of animal farming industry is likely to bring increasing pollution problem unless effective treatment methods are used. The main problems related to the pig farm include odor nuisance and pig manure disposal. The existing land application of piggery wastewater is the traditional way to discharge the wastewater. This may yield in land and water contamination, due to the accumulation of unused nutrients by crop plant. A case study of a large commercial pig farm from Australia is proposed to apply in smaller scale in Indonesia. Operational strategies for the small-scale SBR (Sequencing Batch Reactor) treating piggery effluent were developed based on lab-scale experiments. Due to SBR characteristics, which are money-saving and space-saving, it is very suitable to be applied in urban area. An economic evaluation was made of various process options. The cost estimation showed that SBR is a cost effective process, allowing operational batches to be adjusted to reduce unnecessary aeration cost. A reduction in the aeration cost was achieved by shortening the batch time from 24-h to 8-h. A comparison of three different SBR options showed that smaller size reactors could be more flexible and cost effective when compared with the larger ones.

The most essential scientifific and practical task in the area of ecological safety of pipelines operation is the development and improvement of methods of purifification and restoration of oil-contaminated soils. One of the most effificient and cost effective methods is electrochemical purifification, that does not require the use of expensive chemical reagents and soil excavation. However, the consideration of non-uniform contamination of various soil sections is required. The article examines the features of the organization and technological infrastructure for electrochemical purifification of non-uniformly contaminated soils when using a single electrical energy source, a method for calculating the design parameters of the corresponding installation is proposed. Effificient purifification of non-uniformly contaminated soil when using a specifified voltage is possible through the use of different-sized electrodes. For each soil type, the amount of transmitted electric charge required for soil purifification is determined by the concentration of the contaminant. Allocation of cathodes and anodes as parallel batteries and their connection using individual buses is an effective and energy-effificient solution, since an almost-uniform electric fifield is created in an inter-electrode space, thus allowing the reduction of the interelectrode resistance of the medium.
