Recycled shells of mollusks native to the Mediterranean Sea were used to manufacture the synthetic floor of the athletics track, as part of the Games’ commitment to sustainability.

Traditionally, the athletics track in an Olympic stadium is red. However, at the 2024 Summer Olympics , it's purple, to match the event colors chosen by the Paris organizing committee. But there's another difference: It's made with recycled shells produced by the fishing industry, as part of the 2024 Olympics ' commitment to sustainability. Resilient flooring, such as running-track flooring, is made using calcium carbonate, which is usually obtained through mining.

Mining of limestone and marble to gather calcium carbonate produces carbon emissions, as well as mining waste. According to Mondo, the construction of a track using biogenic calcium carbonate offsets the emissions of a Euro 4 diesel vehicle driving 60,000 kilometers. “The project serves as a forward-looking example of a long-term commitment to sustainability and local communities,” Nieddittas said in a press release.
