Fruity cleanup

Scientists in Mexico have demonstrated how fruit peels can be used to cleanup waste water, removing organic pollutants and heavy metals. The food industry produces tens of millions of tons of fruit peel annually that might be composted but often ends up in landfill with much of the rest of our waste. Now, researchers from the University of Granada and their colleagues have demonstrated an instant controlled pressure drop treatment for waste peel that converts it into an absorbent material that can soak up pollutants in water. The next step will be to take the laboratory-scale demonstration to a bigger scale for testing.
