Two sisters from the Isle of Wight have developed what is claimed as the world’s first fully biodegradable balloon, offering a potential solution for markets like South Africa where party decorations remain popular but environmental pressure is rising.
Charlotte Melia and Christie-Lee Molgaard, both Sandown High School alumni, created Bioloon with scientists at Imperial College London. The product uses natural rubber processed without the harmful additives common in conventional balloons. Researchers say it fully biodegrades within nine months, far faster than standard latex balloons that can persist for years.
The project traces back to the Island. In 2011 Charlotte launched children’s party business Dazzle & Fizz from her kitchen table with £48.50 (R960.00) while eight months pregnant. That venture expanded into international events company D&F Creative, which later funded the Imperial research.
Charlotte, Bioloon’s CEO, has said the idea emerged after years in the events industry watching balloons discarded after celebrations. A major event left her surrounded by thousands of popped balloons, prompting the search for a better alternative. Christie-Lee, co-founder, linked the problem to childhood memories of Isle of Wight beaches. She recalled deflated balloons, faded ribbons and plastic tangled in seaweed after storms, including balloon strings wrapped around seabirds.
“I grew up on the Island’s beaches and I’m raising my own family here now,” she said. “Bioloon is for the beaches I grew up on and the ones my children play on today.”
After about three and a half years of collaboration, Bioloon emerged. The sisters have featured on BBC One’s Sunday Morning Live and BBC News, with international coverage following. Commercial availability is expected within two years.
South Africa’s party balloon market provides a clear opportunity for such innovation. Valued at around USD 48.1 million in 2025, it is projected to reach USD 72.74 million by 2034, growing at a compound annual rate of roughly 4.7 percent. Demand is driven by birthdays, weddings, baby showers, corporate events, school functions and festivals. Latex balloons currently dominate because of low cost and versatility, but biodegradable and eco-friendly options are gaining ground.
Rising environmental awareness and tighter rules on single-use plastics are shifting preferences. Event organisers and consumers increasingly seek alternatives for outdoor and public celebrations. Local suppliers already promote natural latex balloons as biodegradable, yet fully verified rapid-breakdown products remain limited. Bioloon’s nine-month degradation timeline could differentiate it in a market still largely reliant on conventional materials.
South Africa’s broader biodegradable plastics sector is expanding faster, reflecting national sustainability goals. While party balloons form a smaller niche, the combination of steady volume growth and regulatory pressure creates space for cleaner products. Outdoor events along the coast and in nature reserves, where litter is highly visible, make biodegradable balloons particularly relevant.
The Isle of Wight sisters emphasise that their breakthrough began as a kitchen-table start-up. Charlotte has called Bioloon a CleanTech venture aimed at moving laboratory science into commercial use. For markets such as South Africa, where celebrations are frequent and environmental concerns are mounting, the timing aligns with demand for practical, lower-impact alternatives.
If Bioloon reaches the market as planned, it could help reduce the lasting waste left by traditional balloons while serving the growing need for festive, affordable decorations.
