Cleaning up lakes and oceans

Read the full story from Northwestern University.

With a sponge that looks like one you might find in your kitchen, Northwestern University researchers have discovered how to effectively clean up oil, microplastics and phosphate pollution.

This sponge could help clean up oil spills without harming marine life and prevent algae blooms from forming when phosphate builds up to dangerous levels. To recover and reuse dwindling natural resources — like oil and phosphate — the sponge can simply be wrung out.

Northwestern engineer Vinayak Dravid, who developed the new tool, said the novel technology can accommodate multiple functions, much like a Swiss Army knife. The sponge absorbs 99% of phosphate ions it encounters and 30 times its weight in oil.
