Video Illustrates Materials Used in Smartphones and Amounts

Check out the video below from the Sustainable Earth Institute of the University of Plymouth (in the UK).

Besides allowing one to vicariously experience childish glee at watching the destruction of a smartphone by blender (which we of course should NOT try at home), the video provides a brief glimpse at the process of analyzing materials in a lab. Most importantly, it does an excellent job of helping viewers visualize the relative amounts of materials present in the phone, including coins for comparison to a familiarly-sized object (few of us know what 0.7 g or 10 mg really looks like without a reference object for comparison).

The video goes a step further by providing a visualization of the relative amounts of those component elements which would be present in a year’s worth of smartphone production, with a human figure and soccer pitch provided for reference. It’s a great example of how to effectively translate abstract statistics into accessible, meaningful information for the general public.

This would be excellent for presentation to students of all ages, as part of discussions related to industrial design, materials sourcing and impacts, why reclamation of materials from electronics is so important, etc.
