Circular Economy Model Boosts Plastic Recycling Efficiency by 157% at Sporting Events

Why It Matters

This research demonstrates that a focus on efficient waste management, rather than outright elimination of certain materials, can lead to substantial environmental improvements. It offers a practical framework for event organizers to reduce their ecological footprint and align with circular economy principles.

Key Finding

The new model dramatically improved plastic waste management, leading to a significant increase in recycling and a substantial decrease in landfill waste. It was also found to be economically viable under certain market conditions and positively received by participants.

Key Findings

• Plastic collection efficiency increased by 120.5%.
• Recycling rate increased by 157.0%.
• Landfill rate decreased by 75.4%.
• The initiative is cost-effective when the virgin PET price is greater than €776/tonne.
• Direct participant engagement and positive perceptions scored highly on qualitative KPIs.

Research Evidence

Aim: To develop and assess a sustainable model for managing plastic waste at sporting events that prioritizes increased collection, sorting, and recycling efficiency within a circular economy framework.

Method: Quantitative assessment using key performance indicators (KPIs) and a visualization tool to compare a new waste management model against previous event editions.

Procedure: A new plastic waste management model was implemented at a marathon event. This model focused on enhanced collection and sorting for recycling. The environmental, economic, and social impacts were quantitatively assessed using specific KPIs and compared to baseline data from previous events. A visualization tool was used to present the findings.

Context: Sporting events, specifically marathons, with a focus on plastic waste management.

Design Principle

Maximize material recovery and recycling through efficient collection and sorting systems to achieve a circular economy for waste generated at events.

How to Apply

When designing for events, integrate comprehensive waste management plans that include dedicated collection points for recyclables, clear signage, and partnerships with recycling facilities to facilitate a circular approach.

Limitations

Economic viability is contingent on fluctuating virgin material prices. The study focuses on a specific type of event (marathon) and may require adaptation for other event types.

Student Guide (IB Design Technology)

Simple Explanation: Instead of trying to ban all plastic at big events, it's better to collect and sort the plastic waste really well so it can be recycled. This makes the event much more environmentally friendly and can even save money.

Why This Matters: This research highlights that sustainability in design projects isn't just about choosing eco-friendly materials, but also about how products and waste are managed throughout their lifecycle, especially in large-scale applications like events.

Critical Thinking: To what extent can the 'plastic-free' approach be truly sustainable if it leads to the use of less efficient or more resource-intensive alternative materials?

IA-Ready Paragraph: The management of plastic waste at sporting events presents a significant challenge. Research by Bianchini and Rossi (2020) demonstrates that a circular economy model, focusing on enhanced collection and sorting rather than outright elimination of plastics, can lead to substantial improvements. Their study reported a 157.0% increase in recycling rates and a 75.4% decrease in landfill rates at a marathon event, highlighting the potential for significant environmental gains through efficient waste management systems.

Project Tips

• Consider how waste is generated and managed in your design project.
• Research local recycling capabilities and infrastructure when planning for waste disposal.
• Explore how user behaviour can be influenced to improve waste sorting and collection.

How to Use in IA

• Reference this study when discussing waste management strategies for your design project, particularly if it involves events or large-scale material use.
• Use the findings on increased recycling rates and reduced landfill as evidence for the effectiveness of your proposed waste management solutions.

Examiner Tips

• Demonstrate an understanding of circular economy principles in waste management.
• Quantify the environmental impact of waste management strategies in your design project.

Independent Variable: ["Implementation of a circular economy waste management model (vs. previous model)."]

Dependent Variable: ["Plastic collection efficiency","Recycling rate","Landfill rate","Economic cost-effectiveness","Participant perception/engagement"]

Controlled Variables: ["Type of event (marathon)","Type of waste (plastic)","Technological level of recycling plant"]

Strengths

• Quantitative assessment of environmental, economic, and social impacts.
• Comparison with baseline data from previous event editions.
• Inclusion of participant feedback.

Critical Questions

• How scalable is this model to different types of sporting events and venues?
