Sustainable wedding balloons are natural latex balloons, used indoors or in a contained setting, tied down and collected afterwards. Never release them. "Biodegradable" describes the material. It says nothing about where a balloon ends up if it floats away. This guide covers what to buy, what to ask your supplier, and how to plan the collection so your decor stays green after the last dance.
Key takeaways
- Choose natural latex made from rubber tree sap, and ask for EN71 certification, the European toy safety standard.
- Biodegradable does not mean instant. Balloons still need to be collected and binned, not released or left on the lawn.
- Some South African venues ban balloons outright, so confirm the rules before you order.
- Go helium-free with arches, garlands, sticks and centrepieces. They are easier to anchor and easier to collect.
- Balloons work best as one element in a decor plan that also uses flowers, rental pieces and reusable items.

What makes a wedding balloon sustainable
A balloon is sustainable because of three things: what it is made of, how it is used and what happens to it afterwards. Most people only think about the first.
Material. Natural latex is tapped from rubber trees. Our balloons are made from that sap, which is why we describe them as 100% natural and biodegradable. Foil balloons are a different product. They are a coated film, they do not break down the way latex does, and they are better thought of as reusable items than as compostable ones. If you are weighing the two, our comparison of foil and latex balloons for events explains why the word "biodegradable" can mislead.
Use. A balloon tied to an arch, a table or a backdrop stays where you put it. A balloon released into the sky does not. Releasing balloons is the single practice that turns a natural product into litter.
End of life. Plan who collects the balloons, where they are put and what the venue does with them. Without that plan, even the best material becomes someone else's clean-up.
Is biodegradable latex really biodegradable?
Yes, natural latex is a plant-based material that breaks down over time. But it breaks down over months, not days, and that surprises many couples. A balloon left outdoors will still be there on the morning after your reception.
We have tested our own stock and wrote up the results for event planners: balloons that were still intact after 16 weeks. You can read the detail in our guide to biodegradable latex balloons for event planners. The takeaway is simple. Biodegradable is a reason to choose latex over plastic. It is never a reason to be relaxed about litter.
Why you should never release wedding balloons
Balloon releases are popular in photos and a poor idea in practice. Fragments of balloon are a hazard to wildlife and to small children, which is why some places ban them. The Lapeng-Lapa area at the Walter Sisulu National Botanical Garden, a well-known wedding setting in Johannesburg, prohibits balloons because the fragments harm wildlife, the environment and small children.
Two practical points follow:
- Ask your venue about its balloon policy before you design anything. Gardens, nature reserves and wine estates may restrict them, or ask that they stay indoors.
- Keep balloons tethered. Weights, frames, sticks or well-tied arch kits all do the job. If a gust of wind can take your balloon, it can take it off the property.
If the venue does allow balloons, treat that as permission to use them well, not as permission to leave them behind.
Go helium-free for easier, tidier decor
Helium balloons float away the moment a knot slips. Air-filled decor does not. It also lets you build bigger, more polished pieces that stay put through a long evening.
Options we suggest for weddings:
- Arches and garlands. Organic or structured arches around the ceremony or entrance. Our guide to arch kits, DIY or pro helps you choose how much to take on yourself.
- Centrepieces. Compact balloon pieces for guest tables, covered in five helium-free centrepiece styles.
- Bouquets and backdrops. Clusters on stands or walls for the cake table and photo corner, with four balloon bouquet ideas to start from.
- Sticks instead of string. Easy to carry, easy to stash and easy to collect, as explained in balloon sticks versus string.
For a wider look at the approach, see our piece on helium-free balloons and polished decor without a tank.
Choosing colours that suit a green wedding
Sustainability does not mean beige. Natural latex comes in a wide palette, and we stock over 50 colours, so you can match your florals, bridesmaid dresses and table linen closely. A few tips:
- Pick two or three main colours and one accent. Fewer colours look more expensive and use fewer balloons.
- Consider double-stuffed balloons for richer, more opaque shades. See double stuffed balloons and event palettes.
- Avoid glitter and plastic confetti inside balloons. They undo the point of choosing a natural material.
What to check before you buy
Good questions to put to any balloon supplier, including us:
| Question | What a good answer sounds like |
|---|---|
| What are the balloons made of? | Natural latex from rubber tree sap, with no plastic coating |
| Are they certified? | EN71 safety certification |
| Can I see the full colour range? | A clear list with real photos |
| Do you support helium-free builds? | Arch kits, sticks and frames available |
| Who sets up and who collects? | A named team and a clear clean-up plan |
| Can the decor be reused or repurposed? | Yes, for frames, sticks and accessories |
Be cautious with vague claims such as "eco" or "green" that come with no material, certificate or disposal advice.
Plan the clean-up
When the party ends, balloons are the easiest thing to forget. Decide in advance:
- Who deflates and removes the arch, on the night or the next morning.
- Where the used latex goes. Our guide on whether balloons can be recycled in South Africa explains the options and what to do when recycling is not available.
- Whether the venue sorts its waste. Large venues such as the CTICC say they separate recyclable, non-recyclable, compostable and hazardous waste at the source whenever possible, so ask your own venue what it offers.
Reusable parts, such as frames, stands and sticks, should go home with you or back to your supplier.
Balloons are one part of a sustainable wedding
The best sustainable weddings mix materials. South African coverage of current wedding trends describes sustainable decor built around potted orchids, repurposed vintage or rental pieces and natural materials that can be reused or composted. The same article notes that floristry is moving away from plastic oasis foam towards chicken wire, reusable pin holders, moss, branches or biodegradable supports.
Balloons sit well alongside these. A latex garland can frame a doorway, while flowers and greenery fill the tables. If you want zero balloons for a specific venue, good alternatives include fabric banners, paper bunting, potted plants, bubbles and fairy lights.
Perspective: our view on green balloons
We make and supply balloons for a living, so we are not going to tell you balloons are harmless. Any product becomes litter when it is released or abandoned. What we can say is that the material matters. Natural latex from sustainable rubber tree sap is a better starting point than plastic, and it is why we built our range around it, with EN71 certification behind it.
Our honest advice: choose natural latex, keep it tethered, build helium-free, collect everything, and respect venue rules. Do that and balloons can be part of a wedding you feel good about.

FAQ
Are biodegradable balloons safe to release at a wedding?
No. Biodegradable means the material breaks down over time, not that it is safe for animals or children while it does. Some South African venues, such as the Lapeng-Lapa area of the Walter Sisulu National Botanical Garden, ban balloons for this reason. Keep balloons tied down and collect them afterwards.
Are foil balloons more sustainable than latex?
Not automatically. Foil balloons are not biodegradable, so they only make sense if you reuse them many times. Natural latex breaks down over time, but it still has to be disposed of properly. The right choice depends on whether you will reuse the balloons.
Can I have balloons at my wedding without helium?
Yes, and we recommend it. Arches, garlands, bouquets and centrepieces all work with air-filled balloons. They stay where you put them and are easier to collect at the end of the night.
What can I use instead of balloons?
Fabric banners, paper bunting, potted plants, flowers and greenery, bubbles and fairy lights are all common options. Rental and repurposed pieces also keep waste low.
