Eco-friendly nanomembrane removes oil spills

Researchers from Egypt and Saudi Arabia have developed a simple way to manufacture an eco-friendly and affordable membrane that can efficiently adsorb oils spills from sea or waste water.

The membrane can recover quickly and easily for reuse — it can be applied at least 10 times with the same efficiency, according to a study published in Marine Pollution Bulletin.

Leakage of petroleum pollutants into water can be catastrophic to the environment and aquatic life systems. The methods used to remove these pollutants are complex and very expensive; some require use over a long period and involve many workers, while others have a harmful effect on marine and aquatic organisms.

These methods include using chemical dispersants to penetrate the oil and break it up into small pools, setting the oil ablaze at the spill site, or gathering oil from the water surface by mechanical means.

The method that has proved most efficient, in terms of cost and ease of extracting oil, is the use of cheap and eco-friendly adsorbing materials which turn the oil layer to solid or semi-solid particles that can be easily removed.
