Create a mascot that would inform the public of the fact that water they use to wash potatoes can be recycled! Potato water is full of nutrients and can be given to house plants. The mascot could be a pair of sweatpants because sweatpants are like the “potatoes” of fashion. They go with everything. Note: Maybe the mascot’s name could be “Starchy” and his catchphrase could be “make plants grow with tater flow” or something more concise. Statchy’s name could also be stitched onto the butt of the pants.
Side note: Originally this idea was a submission to GOOD’s Reduce Our Collective Energy Consumption mascot contest. I realized after the fact that I didn’t really read the guidelines (or the headline) for the project very closely as my submission had nothing to do with energy reduction. When I read “pick an issue” and “create a mascot” in the contest description, I just sort of ran with it.
