With an ability to absorb more than 30 times its weight in oil, the sponge could be used to inexpensively and efficiently clean up oil spills without harming marine life. After squeezing the oil out of the sponge, it can be reused many dozens of times without losing its effectiveness.

What materials can absorb oil?

Polymers. The polymeric absorbents such as polyurethane, polypropylene, polyethylene, and cross-linked polymers are the most commonly absorbent for oil spills. Due to their high porosity, absorbent capacity and hydrophobicity, these polymers have been widely used for the absorption of organic compounds.

What absorbs oil quickly?

Just follow these steps: Sprinkle sawdust, clay kitty litter (not the clumping kind), coconut husks, or a commercial oil-absorbing product on the stain. If you have none of these products on hand, set paper towels on the floor to soak up any wet oil while you make a trip to the store.
