3 Ingenious Ways to Reuse Tuna Cans at Home ♻️🐟
Before you toss that empty tuna can into the recycling bin, take a second look.
Those small, shallow cans are surprisingly useful around the house. With a good cleaning and a little creativity, they can become mini planters, handy organizers, or charming homemade candles.
Repurposing something you would normally throw away is not only budget-friendly—it can also be a fun way to create something useful from practically nothing. Tuna cans have recently been highlighted for exactly these kinds of upcycling projects. (Chowhound)
Here are three simple ideas worth trying.
🌿 1. Turn Tuna Cans Into Mini Planters
One of the easiest ways to reuse a tuna can is to turn it into a tiny planter.
Because tuna cans are shallow, they’re particularly suitable for small plants, seedlings, and some compact succulents. They can also make attractive little herb containers for a sunny windowsill. (Chowhound)
What You’ll Need
- Empty tuna can
- Dish soap and water
- Small nail or awl
- Hammer
- Potting soil
- Small plant, herb, succulent or seedling
- Paint, twine or decorative tape (optional)
How to Make It
1. Clean the can thoroughly.
Remove any remaining tuna, oil and residue. Wash it with hot soapy water and allow it to dry completely.
2. Make drainage holes.
Carefully make several small holes in the bottom of the can. Drainage is important because excess water can collect around plant roots. (Chowhound)
3. Decorate it.
You can leave the metal exposed for a simple look, or wrap the outside with twine, paint it, or add decorative tape.
4. Add your soil.
Fill the container with an appropriate potting mix.
5. Add your plant.
Small succulents, seedlings and compact herbs can work particularly well.
6. Find a sunny spot.
A windowsill or bright indoor location can turn several tuna-can planters into a tiny kitchen garden.
💡 Tip
Place several finished planters together on a decorative tray. The tray can catch excess water and make the collection look like an intentional little garden rather than a collection of recycled cans.
🗂️ 2. Make a Tiny Home Organizer
Tuna cans are also surprisingly good for organizing all those little things that seem to disappear around the house.
Their shallow, round shape works nicely for small objects such as jewelry, hair accessories, cotton balls, craft supplies, buttons, paper clips and other odds and ends. (Hunker)
What You’ll Need
- 2–4 clean tuna cans
- Fabric, paper, paint or twine
- Glue
- Cardboard
- Scissors
- Optional: labels or decorative trim
How to Make It
1. Clean and dry the cans completely.
2. Cover the outside.
Wrap them with fabric, decorative paper or twine, or simply paint them.
3. Create individual trays.
Use each tuna can as a small open container for different categories of items.
4. Make a larger organizer if desired.
Several cans can be arranged inside a cardboard holder to create a tiered storage system.
5. Label each section.
For example:
- Hair ties
- Bobby pins
- Earrings
- Sewing supplies
- Buttons
- Craft items
A similar tuna-can organizer concept has been used to create countertop storage for small household items. (Hunker)
Where Can You Use It?
This little organizer can be useful in almost any room.
Bathroom: cotton balls, hair accessories and small beauty items.
Bedroom: jewelry, rings and earrings.
Kitchen: tea bags, toothpicks or small kitchen odds and ends.
Craft room: buttons, beads, ribbons and sewing supplies.
Office: paper clips, push pins and other tiny supplies.
Suddenly, that empty tuna can doesn’t look like trash anymore.
🕯️ 3. Turn a Tuna Can Into a Homemade Candle
This one is especially fun if you enjoy homemade gifts or DIY home décor.
A clean tuna can can serve as a small container for a candle, creating a simple little piece of décor from something that would otherwise be discarded. Tuna-can candle projects are commonly made with a wick and melted candle wax. (cookist.com)
What You’ll Need
- Clean tuna can
- Candle wax
- Candle wick
- Wick holder or wooden skewer
- Heat-safe container for melting wax
- Optional candle fragrance
- Optional paint, ribbon or twine for decorating the outside
How to Make It
1. Clean the can thoroughly.
Make sure there is absolutely no fish residue or oil left inside.
2. Prepare the wick.
Secure the wick in the center of the can using an appropriate wick adhesive.
3. Melt the wax.
Melt your candle wax using a suitable double-boiler or wax-melting setup according to the wax manufacturer’s instructions.
4. Add fragrance if desired.
If you’re using candle fragrance, add it according to the wax manufacturer’s recommended amount.
5. Pour the wax.
Carefully pour the melted wax into the prepared can, keeping the wick centered.
6. Let it cool completely.
Allow the candle to harden undisturbed.
7. Decorate the outside.
You can leave the can plain for an industrial look or decorate the exterior with materials that aren’t near the flame.
⚠️ Candle Safety
Never leave a burning candle unattended. Keep it away from curtains, paper, children and pets, and place it on a stable, heat-resistant surface.
If the can has sharp or damaged edges, don’t use it as a candle container.
✨ A Few More Ideas for Those Little Cans
Once you start looking at tuna cans as useful containers instead of rubbish, the possibilities grow.
You can also experiment with:
- Mini artificial plant holders
- Pin cushions
- Small craft trays
- Jewelry catch-alls
- Desk organizers
- Decorative centerpieces
- Small gift containers
- Seed-starting containers
The key is that tuna cans are small, shallow and easy to customize, making them particularly useful for little projects. (Good Housekeeping)
🧽 Always Start With a Very Clean Can
This is especially important with tuna cans.
Wash away all food residue and grease with dish soap and water, then allow the can to dry completely before using it for a craft project.
Be careful when handling the metal. Some cans can have sharp edges, especially around the opening, so don’t run your fingers around the rim to check it.
If the edge is sharp or damaged, it’s better to recycle the can rather than turn it into a project where someone could get cut.
♻️ Why Reuse Instead of Tossing?
Upcycling doesn’t have to mean turning your entire house into a craft project.
Sometimes it’s as simple as looking at an everyday object and asking:
“Can I use this for something else?”
An empty tuna can has already served its original purpose. Giving it a second use can save you from buying another little container or planter while also giving you an opportunity to make something that fits your home.
And perhaps the best part?
It costs almost nothing.
