If your baby drinks formula, the empty tins pile up fast. Within a few months, many families have a cupboard full of sturdy cans, plastic lids and a growing collection of scoops. It feels wasteful to throw them out, but it is not always clear what can go into the recycling bin. This guide covers how to handle a formula milk tin recycle run properly, which parts are recyclable, and practical ways to reuse or donate tins so they get a second life.

Know What Your Tin Is Made Of
Formula containers are not all the same, and the material decides what you can do with them. Look at the packaging and any recycling symbols before you sort.
- Metal tins. Most traditional formula tins are steel or aluminium cans, often with a peel-off foil seal and a plastic lid. Metal cans are among the most recyclable items you can put in the blue bin.
- Composite canisters. Some brands use a cardboard tube with a metal base and rim. These mixed materials are harder to recycle because they are difficult to separate.
- Plastic tubs. Some formula comes in rigid plastic containers with a hinged lid.
- Bag-in-box packs. Refill packs use a cardboard box with an inner foil-lined bag. The outer cardboard is usually recyclable once clean and flat; the inner bag, which combines materials, often is not.
If a container mixes materials that cannot be separated easily, it may be better to reuse it than to put it in the recycling bin.
Cleaning and Sorting Tins for the Blue Bin
Singapore’s blue recycling bins, found at HDB blocks and many condominiums, accept paper, plastic, glass and metal together in one bin. Contaminated items, such as containers with food residue, can spoil a load of otherwise good recyclables, so preparation matters.
Follow these steps:
- Empty it completely. Tap out any remaining powder. Formula left inside attracts ants and can cake when damp.
- Peel off the foil seal. Foil seals with stuck powder are best wiped clean; if it cannot be cleaned, put it in general waste.
- Rinse and dry. A quick rinse with water removes residue. Let it dry so it does not smell in the bin.
- Separate the lid. Clean plastic lids can go into the blue bin separately.
- Mind the edges. Opened tin rims can be sharp. Handle with care and do not crush them with bare hands.
The National Environment Agency (NEA) publishes guidance on what can and cannot be recycled in the blue bin, including its Recycle Right resources. If you are unsure about a specific item, check NEA’s current list rather than guessing. When in doubt, putting a contaminated or non-recyclable item in general waste is better than spoiling a recycling load.
| Part | Blue bin? | Best option |
|---|---|---|
| Clean metal tin | Yes | Rinse, dry and recycle, or reuse |
| Plastic lid | Usually yes, if clean | Recycle or keep with the tin for reuse |
| Foil seal with residue | No | General waste |
| Composite cardboard and metal canister | Often not | Reuse for storage or crafts |
| Plastic scoop | Check NEA guidance | Reuse around the home or donate for crafts |
What to Do With the Scoops
Every tin comes with a scoop, so they accumulate quickly. Small plastic items can be tricky in recycling systems because they may slip through sorting machinery, so check NEA’s guidance before putting them in the blue bin.
There is one important safety point first: always use the scoop that comes with the formula you are using. Scoop sizes differ between brands and products, and using the wrong one can change how concentrated the feed is. Keep the correct scoop inside the tin, and set old ones aside so they do not get mixed up. If you have questions about preparing formula, follow the instructions on the tin and ask your paediatrician or polyclinic. Our guide to formula and bottle feeding in Singapore covers the basics.
Once you have retired old scoops from feeding duty, they have plenty of uses:
- Measuring rice, detergent powder or pet food
- Scooping potting soil or fertiliser for plants
- Sand and water play for toddlers
- Portioning dried beans, oats or flour in the kitchen
Practical Ways to Reuse Formula Tins
Formula tins are strong, airtight and often come with a well-fitting lid, which makes them genuinely useful around the home. Reuse is often the greenest option because it keeps the item in service without any processing at all.
Household storage ideas:
- Dry goods such as rice, beans, pasta and biscuits (clean and dry thoroughly first)
- Bathroom storage for cotton buds, hair ties or spare toiletries
- Craft supplies, crayons and markers
- Spare cables, chargers and batteries
- Sewing kits, buttons and threads
For the garden and balcony:
- Planters for herbs or small plants. Make drainage holes in the base carefully, and add a layer of stones.
- Storage for gardening tools and seed packets
For children:
- Toy storage for blocks or small figurines
- A simple drum or shaker, made safe by taping any rough edges
- Coin banks or “savings jars” with a slot cut in the lid
- Decorated pencil holders for school
Always smooth or tape over any sharp metal edges before giving a reused tin to a child, and supervise young children with homemade toys. If you enjoy upcycling, our ideas for leftover mooncake boxes and tins work well for formula tins too.
Donating Tins and Scoops
If you have more tins than you can use, others may welcome them. Possible takers include:
- Preschools, childcare centres and kindergartens, which often use clean containers for art and craft projects
- Primary school art teachers or CCA groups working on recycling-themed projects
- Community centres and residents’ groups running upcycling workshops
- Online community groups for giving away items for free, where crafters and gardeners often ask for sturdy containers
Before dropping off, ask what they need, because many organisations have limited storage. Only donate tins that are clean, dry and free of sharp edges. Unopened formula is a different matter: if your baby has switched brands or moved on, as many do when switching from formula to fresh milk after one, some charities and family support organisations may accept sealed, unexpired tins. Contact them first to confirm what they accept.
Small Habits That Add Up
A family using formula for a year can go through a surprising number of tins. A few simple habits make it easier to handle them well:
- Keep a small box near the kitchen for rinsed, dried tins waiting to be recycled or reused.
- Separate lids and scoops as soon as a tin is empty.
- Choose larger pack sizes or refill packs if they suit your baby, to reduce packaging overall.
- Pass on spare tins regularly rather than letting them pile up.
With a bit of planning, empty formula tins can become storage, planters, toys or craft supplies for someone else, instead of just more rubbish.
