Have people dress up as "recyclables", and one person chasing them around. For example, a bit chasing a water bottle that is trying desperately to get into a stream. Have him chase down several things with kooky music, and at the end say "Recycling, it doesn't have to be that hard".
Some of the funny ideas could be showing people tossing trash into a receptacle and serving a recyclable packaging for dinner. You can keep recycling the video and then at the end, you tell people that there is no more food left because there is no room for landfills.
