Cleaning up oil spills is a time consuming, difficult process. But a novel approach developed at the Norwegian University of Science and Technology (NTNU) uses a new kind of vacuum cleaner that blows bark or other absorbent material onto oil spills, and then sucks the material up again. The vacuum cleaner is four times more efficient in cleaning up after oil accidents than conventional techniques.
