Record-breaking solo yachtswoman Dame Ellen MacArthur is in Davos to promote a new approach towards a sustainable economy.

She wants products to be made that they are easy to disassemble in order to re-cycle the parts inside.

She claims that the approach, called a circular economy, could mean savings of $630bn for Europe alone.
