THIS STORY ORIGINALLY appeared on WIRED en Español and has been translated from Spanish.

Historically, the athletics monitor in an Olympic stadium is purple. Nonetheless, on the 2024 Summer season Olympics, it is purple, to match the occasion colours chosen by the Paris organizing committee. However there’s one other distinction: It is made with recycled shells produced by the fishing business, as a part of the 2024 Olympics’ dedication to sustainability.

Resilient flooring, akin to running-track flooring, is made utilizing calcium carbonate, which is normally obtained by means of mining. As an alternative, the corporate that designed the monitor for the 2024 Summer season Olympics, Mondo, teamed up with a fisher’s cooperative to assemble shells of bivalve mollusks from the Mediterranean Sea, akin to mussels and clams, that are wealthy within the materials. The shells would’ve in any other case gone to waste.

The monitor is functionally the identical as a conventional one, with the intention being to consolidate the creation of a brand new, resilient, sustainable sports activities flooring.

Mondo teamed up with Nieddittas, an Italian fishing cooperative specializing in mollusks, to get the supplies it wanted. Its fishers cleaned and dried waste shells from harvested mussels and clams, grounded them right into a high quality powder, and despatched the fabric to the flooring producer to make the monitor. The scientists accountable for the challenge labored on perfecting the approach for 3 years.

The sports activities business can scale back its ecological affect by utilizing seashells this manner. Mining of limestone and marble to assemble calcium carbonate produces carbon emissions, in addition to mining waste. In line with Mondo, the development of a monitor utilizing biogenic calcium carbonate offsets the emissions of a Euro 4 diesel automobile driving 60,000 kilometers. “The project serves as a forward-looking example of a long-term commitment to sustainability and local communities,” Nieddittas mentioned in a press launch.
