Maybe it looks more amazing in person than in pictures. If not, and the point is a message about waste, then the 80% increase could be cast as part of the message.

Let’s say every month the artist repurposes the last pile of plastic with more glue. At the end of one year, the 10lbs would turn into 1100lbs. At the end of two years the original 10lbs would have turned into 1.3 million lbs of plastic waste. Surely that would frame a very powerful message about plastic waste and green washing misleading public policy.
