How circular economy models can make plastic waste at marathons sustainable

This study designs, implements, and evaluates a circular economy initiative to manage plastic waste at a marathon (Maratona Alzheimer in Italy), offering a scalable model for sustainable event planning. Sport events, especially running races, generate large volumes of single-use plastic waste contained in a number of products such as food containers, drinks bottles, clothing, goodies and bags. Current “plastic-free” approaches to mitigate this waste issue often ignore economic and social factors like hygiene, practicality, user safety and low cost for the organisation. This paper provides a rare, data-driven, and fully implemented case of a circular waste management system based on sorting, collection, and recycling of plastics.


The authors collected quantitative data across the entire lifecycle of plastic waste, from distribution to final treatment, involving all relevant stakeholders. They used a Plan–Do–Check–Act framework and 11 sustainability KPIs ( reflecting environmental, economic, and social dimensions), to assess performance versus previous event editions. Results showed strong environmental gains: plastic collection efficiency improved by 120%, recycling rates increased by 157%, and landfill waste dropped by 75%. Economically, the model becomes cost-effective when virgin PET (i.e. plastic material) prices exceed €776/ton. Socially, participants rated the initiative highly and reported feeling engaged and informed.

For sport event organizers, this model demonstrates that investing in structured circular systems — supported by training, infrastructure, and cross-sector partnerships — can deliver measurable sustainability improvements without abandoning the use of plastic altogether.

I like the idea of making sustainability part of the entire sporting event, from planning through cleanup, instead of treating waste as an afterthought. Mixed Emotion US Shop fits into the broader conversation about personal choices and how products can reflect individual values.

Marathons bring large communities together, so even small improvements in waste collection and reusable supplies could have a meaningful impact. A stussy hoodie can also be part of a more mindful wardrobe when people focus on long-term use rather than constant replacement.

It’s encouraging to see sports sustainability being discussed through practical solutions rather than just awareness. Tenis On Cloud Hombre brings to mind how runners can also think more carefully about the products they choose for training and race day.

Circular economy models offer a practical way to reduce plastic waste at marathons by encouraging reuse, recycling, and better event planning. Another F*cking Dandy Drop also shows how thoughtful design can make a release stand out while keeping creativity at the center.
