9 Creative Ideas for Reusing Tuna Cans
Every year, millions of tuna cans end up in landfills—yet these small, sturdy metal containers have so much potential beyond holding your favorite fish! Whether you’re into DIY projects, home organization, or eco-friendly living, tuna cans can be repurposed in fun and functional ways. Instead of tossing them out, give them a second life with these 9 creative reuse ideas that are both practical and sustainable.
1. Mini Planters for Herbs or Succulents
Tuna cans make perfect mini planters for small plants. Clean the can, drill a few drainage holes at the bottom, and fill it with soil. These compact planters are ideal for growing herbs like basil, mint, or thyme on your windowsill, or for displaying cute succulents on your desk or shelf.
2. Desk Organizer
Tidy up your workspace by turning tuna cans into holders for pens, paperclips, rubber bands, and more. You can paint or wrap the cans in decorative paper to match your office décor. Stack or glue multiple cans together for a multi-compartment organizer.
3. Candle Holders
Tuna cans are a great base for homemade candles. Simply melt wax, add a wick, and pour it into the can. You can add essential oils for scent and even layer colored wax for a unique look. These make lovely gifts or additions to your own cozy home décor.
4. Magnetic Storage Containers
Glue a strong magnet to the back of a clean tuna can and stick it to your refrigerator or a magnetic board. These containers are perfect for storing spices, screws, nails, beads, or other small items. Add clear lids or label the fronts for easy identification.
5. DIY Bird Feeder
Invite birds into your garden by turning a tuna can into a bird feeder. Fill it with seeds and hang it using string or attach it to a wooden perch. Make sure to smooth the edges to avoid injury to the birds. This is a great project to do with kids, too!
6. Wall-Mounted Tea Light Holders
Attach cleaned and decorated tuna cans to a piece of wood or directly to the wall to create a rustic wall-mounted tea light display. Place a tea light candle inside each can for a warm and stylish wall accent—great for patios or cozy indoor corners.
7. Mini Baking Molds
Tuna cans can be used as molds for baking small cakes or quiches. Remove the top and bottom lids, grease the interior well, and place the can on a baking sheet before filling. Be sure to use BPA-free cans if you’re going to reuse them for food.
8. Jewelry or Trinket Holder
Decorate the interior and exterior of the can with fabric, paper, or paint, and use it to store earrings, rings, and other small accessories. You can also add a lid or stack several for compact storage on a vanity or dresser.
9. Craft Supply Caddy
For crafters and hobbyists, tuna cans can help organize buttons, thread, sequins, needles, and other tiny materials. Arrange multiple cans inside a drawer or glue them onto a lazy Susan for a rotating supply caddy that keeps everything accessible.
Final Tip: Safety First!
Always make sure the edges of the can are smooth. If necessary, use a metal file or wrap the rim with washi tape or fabric to avoid cuts.
Reusing tuna cans isn’t just eco-friendly—it’s a fun way to get creative and stay organized! These small metal containers can serve a surprising number of purposes around your home.
