Solidification of petroleum-based tar material with capping was selected as the closure methodology for a former nonhazardous industrial waste landfill in the Eastern United States. While more expensive in the short term, this closure approach met the major long-term goals of the customer (site owner): rapid exit strategy, salability, and reduced long term monitoring. Value engineering changes ...

This paper presents two interval parameter fuzzy programming models for the planning of petroleum solid waste management systems under uncertainty. In these models, fixed violation limits are introduced to relax the critical constraints so that the results produced by these models give more useful information to decision makers. These two models are also applied to a hypothetical planning probl...

A hydrophobic biocomposite (HBC) has been developed using a waste wood residue for circumventing oil spill issues. The ease of removal, regeneration and recyclability is demonstrated.

human activities such as oil and gas production can enhance the natural level of naturally occurring radioactive materials (norm) in by-product and waste streams. iran has been among the top five oil producing countries since 2005. this high production rate emphasizes the importance of norm management to ensure the safety of humans and wildlife. petroleum storage and transport facilities are lo...

Studies on earthworms using molecular markers are rare in Africa except a handful from South Africa. Reports on Libyodrilus violaceous,an earthworm found in West Africaare available including their metal tolerance and bioaccumulation capacity but their molecular characterization and ecotoxicology studies are scarce. In this study, triplicate L. violaceous specimens were collec...

Abstract The offshore petroleum industry operates in a harsh environment, which poses great safety risk and accident rescue difficulty. With the increasing volume of world oil transportation vigorous development exploration business, number marine spill accidents has increased significantly, will cause huge pollution to ecological environment also attract widespread attention from media public....

The oil released during the Deepwater Horizon (DWH) oil spill may have both shortand long-time impacts on the northern Gulf of Mexico ecosystems. An understanding of how the composition and concentration of the oil are altered by weathering, including chemical, physical and biological processes, is needed to evaluate the oil toxicity and impact on the ecosystem in the northern Gulf of Mexico.
