As I drink plastic bottles of water or Diet Pepsi, I throw the empty bottles over my shoulder along with used paper towels. I try to keep any food wrapping in one place. After each day, I clean out any food wrapping or paper towels that can fly around. I may wait on the plastic bottles in case I can find a place that takes recycling. I also do a complete cleaning and organization before each new chase day. As for files, I usually have a few crumpled pieces of paper in a slot inside my laptop case. As for receipts, they usually accumulate in my wallet and eventually get stuffed in a plastic zip lock bag to take home.
