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 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 ...
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. [3]
Deepwater Horizon oil spill site with visible oil slicks. Fungi are amongst the primary saprotrophic organisms in an ecosystem, as they are efficient in the decomposition of matter. Wood-decay fungi, especially white rot, secrete extracellular enzymes and acids that break down lignin and cellulose, the two main building blocks of plant fiber.
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.
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.
A percolation test consists of digging one or more holes in the soil of the proposed leach field to a specified depth, presoaking the holes by maintaining a high water level in the holes, then running the test by filling the holes to a specific level and timing the drop of the water level as the water percolates into the surrounding soil.
Inspector on offshore oil drilling rig. Offshore oil spill prevention and response is the study and practice of reducing the number of offshore incidents that release oil or hazardous substances into the environment and limiting the amount released during those incidents.
