Background

Oil recovery systems that use a sponge to soak up the contaminated oil may be reused and then may be disposed of because they become less efficient with subsequent re-use.

Technology

Researchers at Stony Brook University have created an oil recovery sponge which can be used 3 to 20 times without decreasing its efficiency of absorption. The sponge is a natural porous substrate (luffa sponge) treated with silicon material rendering it hydrophobic and capable of absorbing other materials including oil. Oil spills adversely affect the environment and massive oil spills can result in long-term disastrous effects. Experimental cycle tests and data on absorption and recyclability have performed with consistent results.

Advantages

Uses natural materials - Simple fabrication - Materials can be used multiple times

Application

Oil recovery systems.
