Oil spills happen frequently at varying degrees along with all aspects of the petroleum supply chain, presenting a complex array of issues for both environmental and public health. [1] While traditional cleanup methods such as chemical or manual containment and removal often result in rapid results, bioremediation is less labor-intensive ...
Sorbents collect specific liquids or gases depending on the composition of the material being used in the sorbent. Some of the most common sorbents used to clean oil spills are made from materials that are both oleophilic and hydrophobic, have high surface area through structural designs that include pores and capillaries, and draw in liquid through capillary action.

Oil dispersant mechanism of action. An oil dispersant is a mixture of emulsifiers and solvents that helps break oil into small droplets following an oil spill.Small droplets are easier to disperse throughout a water volume, and small droplets may be more readily biodegraded by microbes in the water.
PRP was created in the 1990s by NASA’s Jet Propulsion Laboratory and has been used to assist in remediating oil spills such as the 2010 Deepwater Horizon oil spill. [ 1 ] [ 2 ] PRP is a powder composed of microscopic hollow spheres of wax up to 150 microns in size.
Bioremediation is not specific to metals. In 2010 there was a massive oil spill in the Gulf of Mexico. Populations of bacteria and archaea were used to rejuvenate the coast after the oil spill. These microorganisms over time have developed metabolic networks that can utilize hydrocarbons such as oil and petroleum as a source of carbon and ...
According to Dr. Ian Smith, a gasoline spill on a disposable tarp can be absorbed using cat litter. He recommends leaving the cat litter down for at least 48 hours. If you don't have cat litter ...
They worked toward removing oil and tar from beaches and offshore surrounding areas, creating boarders around the spill to keep the surface oil from spreading, using sorbents to absorb the oil, and burning the oil away. One study estimated that 5 to 6 percent of the oil from the Deepwater Horizon spill was burned into the atmosphere.
