The environmental impact of tennis: what nobody tells you about tennis balls

🎾 What is one of the world most popular sports doing to the planet?

Have you ever thought about the environmental impact of tennis? During a conversation with Gabriela Albuquerque, an environmental engineer, we were talking about the Australian Open when a surprising fact came up: the huge amount of waste generated by tennis balls.

That curiosity led me to research the topic more deeply. The numbers are alarming and reinforce the need to discuss sustainability in the sport.

📊 The environmental impact of tennis in numbers

• The US Open uses around 60,000 balls in just two weeks.
• It is estimated that 325 million balls are produced annually, generating more than 20,000 tons of waste.
• On average, each ball lasts only 9 games before being discarded.
• With millions of players across more than 200 countries, global consumption keeps growing.
• If every player used only 5 balls per year, more than 1 billion balls would be discarded annually.
• Wimbledon uses around 54,250 balls each edition. Even though some become souvenirs, most are discarded.
• The Australian Open also uses around 48,000 balls, even if some are repurposed.
• To manufacture 1 million balls, the industry uses around 10 tons of rubber and 50 tons of felt, which means a considerable environmental cost.

🧪 Tennis balls: composition and recycling challenges

Tennis balls are made of rubber and felt, usually with nylon or wool. Even though rubber is theoretically recyclable, the manufacturing process makes recycling very difficult because of how materials are combined.

On top of that, petroleum-based rubber makes the problem worse because the process generates greenhouse gas emissions. The felt also degrades by releasing microplastics, which contaminate soil and water sources.

🚨 Other environmental impacts of tennis

The environmental impact of tennis is not limited to balls:

• Manufacturing depends on fossil fuels and releases large amounts of carbon into the atmosphere.
• Grass or clay courts require intense irrigation and continuous fertilizer use, which directly affects water resources.
• Synthetic courts use plastics that do not naturally degrade, accumulating waste for decades.
• Felt decomposition directly releases invisible plastic particles that are extremely harmful to the environment.

💡 Sustainable initiatives in the sport

Despite the challenges, promising initiatives are already underway to reduce the environmental impact of tennis:

• The US Open donates used balls to schools, social projects, and community programs.
• Some startups already shred tennis balls to transform them into gym flooring and urban pavement.
• Researchers and manufacturers are developing pilot projects with biodegradable balls, and early results look promising.
• Organizations such as ReBounces in the United States and the Tennis Ball Recycling Project in France are building large-scale reuse and recycling systems.

🌍 Conclusion: how can we help?

If you play tennis or simply follow the sport, you can help reduce its environmental impact:

• Reuse balls whenever possible.
• Participate in local donation or recycling initiatives.
• Support sustainable tournaments and brands.
• Share this kind of information to raise awareness.
