Short answer: balloons marketed as "biodegradable" usually do not break down quickly in nature, so treat them as single-use litter unless you commit to secure use and disposal. Tests over several months show little meaningful degradation in typical environments. Never release balloons; plan tethered displays and proper binning. Better materials are in development, but they are not yet widely available.
TL;DR:
- After 16 weeks of testing, balloons labeled biodegradable remained recognizably intact in industrial compost, freshwater, and saltwater, so composting is unreliable.
- Because manufacturing additives and vulcanization alter natural latex, inspect material and coating details, disposal directions, and documentation for any claimed certification before ordering.
- At events, keep balloons indoors or securely tethered, then collect, deflate, cut, and place every piece in a secure waste bin instead of composting them.
- Foil and Mylar balloons do not biodegrade, while ribbons, strings, clips, and sticks can persist or entangle wildlife; avoid these accessories.
- Fabric bunting, paper garlands, bubbles, potted plants, and reusable inflatables offer alternatives, while the Bioloon prototype is not yet commercially available.

What does "biodegradable" on a balloon label actually mean?
Raw natural latex is simply sap from the rubber tree. A finished balloon is something else: the latex has been compounded with additives for stretch, colour and shelf life, then vulcanised. Those steps change how the material behaves outdoors, and scientific analysis of balloon degradation shows that vulcanisation and manufacturing additives make breakdown complex and slow in many natural environments. Environmental experts also warn that biodegradable labelling is often misleading for exactly this reason.
Phrases such as "100% natural latex" describe the starting material, not how fast the finished product disappears. When you read packaging or a product page, check for:
- A statement of what the balloon is made from, not only a marketing claim.
- Any mention of additives, dyes or coatings.
- A named safety standard, if one is relevant to the product.
- Clear disposal instructions, which suppliers should provide.
What does peer-reviewed research say about how fast latex balloons degrade?
Researchers ran a 16-week experiment on balloons sold as biodegradable. Balloons stayed recognisably intact in industrial compost, freshwater and saltwater.
Balloons labelled "biodegradable" stayed recognisably intact after 16 weeks, so they can still pose a risk to wildlife.
The team measured three things:
- Mass change, to see whether material was actually being lost.
- Ultimate tensile strength, which fell in water but not in compost.
- ATR-FTIR spectral analysis, which checks for chemical changes in the material.
Newer work is more hopeful. Imperial College London researchers have built a prototype called "Bioloon" that they claim biodegrades within nine months, and news coverage says it avoids harmful additives. It is a prototype, not a product you can buy today.
How do balloon releases and accessories harm the environment?
The bigger problem is often not the latex but where the balloon ends up. A released balloon can travel a long way, then fragment into pieces that animals mistake for food. Balloon fragments and non-biodegradable accessories create choking and entanglement hazards for wildlife, on land and at sea.
Accessories make things worse:
- Foil and Mylar balloons are not biodegradable, and they can also cause power outages when they touch overhead lines.
- Plastic ribbons and strings persist in the environment and tangle around animals.
- Plastic clips, weights and sticks add more material that never breaks down.
Authorities have noticed. A municipal ban on balloons in nature reserves is one example of local rules that restrict balloon releases in protected areas.
How should you use and dispose of biodegradable-labelled balloons?
Responsible use costs little and removes most of the risk. Follow these steps:
- Never release balloons. Choose indoor displays or securely tethered outdoor ones.
- Pop nothing loose: at the end of the event, collect every balloon and fully deflate it.
- Cut the deflated balloons into small pieces.
- Put the pieces in a secure waste bin. Do not compost them or leave them outdoors.
- Skip plastic ribbons, clips and foil add-ons, or choose paper and fabric alternatives.
- If you need printing, ask your supplier for minimal ink coverage and clarity on materials.
Pro Tip: Assign one person to a "balloon sweep" at the end of the event, so nothing is left behind in gardens, car parks or venues.
How do you choose and buy biodegradable-labelled latex balloons?
Treat the purchase like any other product claim: ask questions and expect answers. A good checklist looks like this:
- Look for a clear material statement rather than only a green slogan.
- Ask about the manufacturing process and which additives are used.
- Verify any certification claim, such as EN71, and ask to see documentation.
- Request samples before a large order, so you can judge quality and colour yourself.
- Set realistic expectations: even natural latex may not degrade quickly, so secure use and disposal still matter.
We make our biodegradable latex balloons from rubber tree sap, with custom printing for corporate functions, weddings and private celebrations. If you want to see everything we supply, from decor lines to promotional items, our products page lists it all. Whichever supplier you choose, the questions above apply.
What can you use instead of releasing balloons?
You can get plenty of visual impact without letting anything drift away:
- Tethered balloon clusters: colourful and familiar, but they still need collecting and binning afterwards.
- Bubbles: cheap and joyful, though they leave sticky residue on some surfaces.
- Paper garlands: easy to hang and recycle, but not suited to damp outdoor settings.
- Fabric bunting: reusable year after year, at the cost of a higher upfront price.
- Potted-plant giveaways: guests take them home, though they need more budget and logistics.
- Reusable inflatables: durable for repeated events, but they need storage space.
Balloons can still have a place indoors or in tethered displays, as long as you plan the clean-up before the party starts.
Why can you trust this guide and what do we offer?
We are a balloon manufacturer and printer, so we have a stake in this topic and you should weigh our claims accordingly. These are our own stated proof points:
- Our biodegradable latex balloons are made from rubber tree sap.
- We offer balloons in a range of colours.
- We provide custom printing and event décor services.
- Ask us for details about product certification.
Before any large purchase, ask us (or any supplier) for certification documents and product samples, and compare what you receive against the claims. The research summarised above comes from independent studies and reporting, linked throughout, so you can check it for yourself.
A short perspective on celebrating responsibly
I love what balloons do to a room. They signal that something good is happening. But the evidence says the label "biodegradable" cannot excuse careless use, so I ask planners to hold the line: no releases, tethered displays, proper disposal. Before you order, ask whether an alternative would deliver the same joy with less risk.

FAQ
Can latex balloons be biodegradable?
Natural latex is a plant material, but finished balloons contain additives and are vulcanised, which slows breakdown. In a 16-week test, balloons sold as biodegradable stayed largely intact in compost, freshwater and saltwater. So treat the label as a starting point, not a guarantee.
Which balloon brands are biodegradable?
No brand label can promise fast breakdown outdoors, so judge suppliers by transparency instead. Ask about materials and additives, request certification documents and samples, and check disposal advice. We make our own latex balloons from sustainable rubber tree sap and are happy to answer those questions.
Can you buy biodegradable balloons?
Yes, balloons sold as biodegradable are widely available online and from event suppliers. We offer our balloons in a range of colours with custom printing. Use them indoors or tethered and dispose of them in a secure bin.
Is there an eco-friendly alternative to balloons?
Yes: paper garlands, fabric bunting, bubbles, potted-plant giveaways and reusable inflatables all work. A prototype material called Bioloon is also in development, but it is not yet on sale.
