Natural latex is the starting material for many balloons, but the finished product should not be treated as harmless litter. “Biodegradable” does not mean a balloon will disappear quickly or can safely be released outdoors.
What does the evidence say?
Research by the University of Tasmania tested latex balloons in freshwater, saltwater and industrial compost for 16 weeks and found no meaningful degradation over that period. Conditions matter, and we do not give a guaranteed timescale for balloons to break down.

How to plan an installation responsibly
Keep balloons contained throughout the event and collect every balloon, tie and fragment afterwards. Agree dismantling and disposal arrangements with your venue and installation team. Do not assume that a balloon belongs in a recycling or compost stream just because it is made from latex.
Our standard installations use natural latex balloons, with other materials available where the design calls for them. We prioritise air-filled designs and can discuss the materials, supports and removal requirements in your brief.
