A greener game: space tech conserves water at Roland-Garros
Space technology is playing a key role in making the Roland-Garros tennis tournament greener. The tournament is using water recycling technology originally developed for use in space by the ESA-led MELiSSA (Micro-Ecological Life Support System Alternative) project, which has been developing closed-loop life support and recycling systems for astronauts for over 30 years. These systems will be vital for long space missions to the Moon or Mars.
A water recycling unit developed by the Monaco-based startup FGWRS (Firmus Grey Water Recycling System), which adapted the space technology for use on the ground, has been installed at the training courts of the Paris Jean-Bouin sports club. This unit reclaims up to 80% of grey water from the site's showers, which is then processed and used to flush the toilets. Additionally, nearly 50% of the heat from this grey water is recovered to heat clean water for more showers, saving both energy and precious drinking water.
"We're thrilled to see ESA technology like the MELiSSA water recycling system finding practical applications here on Earth at Roland-Garros," said Aude De Clercq, Head of Innovation Services at ESA. "This project exemplifies the incredible potential of space exploration to drive innovation that benefits our planet and its people. By adapting space technology for water conservation, we're not just saving a precious resource at the tournament, we're inspiring solutions for sustainable water management worldwide."
This innovative technology has been in use at every French Open since 2020, saving over 90 000 litres of water. Sharing the benefits of space with everyone is central to ESA's mission, and the agency is pleased to partner with companies like FGWRS that share its vision for a greener future.
"The French Open's embrace of ESA-developed water recycling technology is a powerful testament to the ingenuity and real-world value of our space programmes,” said Emmet Fletcher, Head of ESA’s Branding and Partnerships Office. “This collaboration not only enhances the sustainability of the tournament but also showcases ESA’s excellence in technological innovation to a global audience. By partnering with forward-thinking organisations like the French Open, we’re raising awareness of ESA’s role in shaping a better future for all.”
