Re-Use What You Use If we re-use what we use every day or change the way we use it; we will have less to throw away in the trash or recycle.   Ways to Help You Re-Use Old towels and clothing can be reused in craft projects or as cleaning rags. That empty butter tub or cottage cheese container can be used again to store food, toys, tools, and more. Reducing the need to buy tupperware or new plastic containers. That old calendar can be reused as wall are. Just cut it apart and add a frame.
