Sports venues have a waste problem. But they also have a business opportunity.
Every match, race and major sporting event creates concentrated flows of materials: cans, PET bottles, food waste, cardboard, packaging, textiles, grass clippings, pallets, signage and temporary event infrastructure.
Most of these materials are still treated as waste.
But what if they were treated as resources instead?
For stadiums, racing circuits, clubs and event organisers, a zero waste strategy can do more than reduce environmental impact. It can reduce disposal costs, create new revenue streams, improve ESG performance, support sustainability certification and create a powerful first-mover position.
The question is no longer simply:
“How do we manage our waste?”
It is:
“How much value are we currently throwing away?”
What does zero waste mean in sports?
Zero waste does not mean that a stadium produces absolutely no waste.
It means designing operations so that materials are prevented, reduced, reused, recovered, recycled, composted or otherwise kept in productive use rather than being sent to landfill or incineration.
This distinction is important.
The goal is not simply to install more recycling bins. A successful zero waste sports strategy looks upstream at what enters the venue, how it is purchased, how it is used, how fans interact with it, and what happens to it afterwards.
The waste hierarchy therefore becomes a practical business strategy:
Prevent → Reduce → Reuse → Recover → Recycle → Dispose only as a last resort.
A useful example is Germany’s PreZero Arena project, home to TSG Hoffenheim. In 2023, the stadium became the first certified Zero Waste stadium in the Bundesliga, independently assessed by TÜV Süd according to DIN SPEC 91436. Its initial certification was based on achieving an 87% recycling rate and putting more than 85% of materials to higher-value use through reuse, recycling, composting and fermentation.
In 2024, the arena progressed to silver certification, with PreZero describing the project as a model for other stadium operators and clubs.
And this highlights a much bigger opportunity:
The race is still open.
Germany already has its pioneer. For stadiums and sports venues in most other European countries, the opportunity remains to become the first certified zero waste stadium or venue in the country.
That is more than an environmental achievement.
It is a first-mover business and brand position.
Why is zero waste particularly important for sports?
Sports venues are unusual environments.
Waste isn’t generated evenly throughout the year. Instead, enormous volumes can be generated within a few hours.
A matchday can bring tens of thousands of people into one location, all consuming food, drinks and merchandise at approximately the same time.
Mega-sporting events create an even greater challenge. The 2012 Olympic Games generated more than 8,250 tonnes of operational waste, illustrating the scale of concentrated waste flows at major sporting events.
A recent academic review by Zafari, Golzary, Rouhi and Mansourihanis similarly describes mega-sporting events as temporary, high-intensity environments that can generate waste volumes reaching tens of thousands of tonnes. The authors argue for a shift from conventional waste management towards integrated circular systems.
At the same time, sports venues involve a complex network of stakeholders:
- Fans and spectators
- Athletes and teams
- Caterers and concessionaires
- Sponsors
- Merchandise suppliers
- Cleaning contractors
- Waste management companies
- Venue operators
- Event organisers
- Local authorities
This means zero waste cannot be solved by the cleaning team alone.
It requires procurement, operations, infrastructure, supplier management, fan engagement and reliable data to work together.
The first step: Know your waste
One of the biggest problems in sports sustainability is surprisingly basic:
Many organisations don’t actually know their waste diversion rate.
They know what they pay their waste contractor.
They may know how many containers are collected.
But they often don’t know:
- How much waste they generate
- What materials make up that waste
- How much is actually recycled
- How much is composted
- How much is reused
- How much is landfilled or incinerated
- Where contamination occurs
- Which materials could generate value
- What their actual waste diversion rate is
Without a baseline, it is almost impossible to demonstrate improvement.
A professional sports waste audit creates that baseline.
It can include on-site observation, waste sampling, categorisation, weighing, supplier and hauler data, contamination analysis and an assessment of the destination of each material stream.
The result is a much more useful question:
Where are the biggest opportunities to reduce waste, save money and generate value?
This is also where credible ESG reporting and sustainability ratings become relevant. The Global Sustainability Benchmark in Sports (GSBS), for example, places importance on waste-related data and documentation, including waste generation, waste intensity, diversion, reduction targets and circular procurement.
The hidden value in a stadium’s waste streams
Not every waste stream has the same value.
Some should be eliminated, some should be reused, some should be donated, some should be donated and some can potentially become a new revenue stream.
This is where the zero waste business case becomes particularly interesting.
Aluminium cans
Imagine a stadium currently putting aluminium cans into a mixed recycling stream.
The cans may become contaminated with other materials, reducing the quality and value of the stream. The venue then pays its waste contractor to collect and process it.
A different model is possible.
Create a dedicated can collection stream.
The venue can then:
Separate → consolidate → sell directly to a recycler or contractor.
Instead of paying to remove a mixed waste stream, the organisation can potentially generate income from a clean, valuable material stream.
The exact commercial value depends on local market prices, purity, volumes, logistics and the contractor agreement — but the principle is straightforward:
Separate valuable materials before they become low-value mixed waste.
And cans are only one example.
Other potential waste-to-value streams include:
PET bottles
Clean, separated PET can be collected and baled for recycling.
Wooden pallets
Pallets can often be repaired, reused, returned or resold rather than discarded.
Carpet tiles
Depending on the material and manufacturer, tiles can potentially be reused, recovered or returned into recycling systems.
Glass
Separating glass at source can improve material quality and facilitate recycling into new glass products.
Food waste
Prevention comes first, followed by redistribution where appropriate, and composting or anaerobic digestion for unavoidable organic waste.
Sports apparel and merchandise
Unused, outdated or damaged apparel can potentially be repaired, donated, upcycled or recycled.
The important point is that the best waste strategy is not necessarily the one with the highest recycling rate.
It is the one that creates the highest overall environmental, financial and social value.
Reuse: The biggest opportunity hiding in plain sight
Sports venues are particularly well suited to reuse.
Why?
Because they are essentially controlled environments.
Fans enter through defined entrances, purchase food and drinks at known locations, and leave through predictable exit routes.
That makes it possible to create effective collection and return systems.
The Green Sports Alliance Reuse Playbook provides practical guidance for sports and entertainment venues implementing reusable food and beverage serviceware systems.
Reusable cups are one example.
But the same principle can apply to:
- Food containers
- Trays
- Cutlery
- Hospitality equipment
- Event furniture
- Signage
- Flooring
- Barriers
- Merchandise
- Staff uniforms
The economic value comes from using the same asset repeatedly rather than purchasing and disposing of a new one for every event.
And reuse can create something recycling often cannot:
a visible fan experience.
A reusable cup can carry a sponsor.
A deposit can support a social cause.
A return station can become part of the fan journey.
Sustainability becomes something people participate in, rather than something happening somewhere behind the stadium.
Food waste: From disposal cost to resource
Food is another major waste stream across stadiums, hospitality areas, VIP lounges and racing events.
The strategy should start with prevention.
Better forecasting, portion management, procurement and inventory control can reduce food waste before it is generated.
Then comes redistribution.
Safe surplus food can potentially be donated to local organisations rather than discarded.
Finally, unavoidable organic waste can be separated for composting or anaerobic digestion where suitable infrastructure exists.
This approach is increasingly reflected in sports-sector sustainability guidance, including resources from the Green Sports Alliance addressing food waste diversion and compostable packaging.
The principle is simple:
Don’t ask first where food waste should be disposed of. Ask why it became waste in the first place.
Sports apparel is a circular economy opportunity
A sports organisation’s material footprint extends far beyond the stadium bins.
Think about:
- Player kits
- Training clothing
- Staff uniforms
- Towels
- Fan merchandise
- Flags
- Banners
- Promotional textiles
- Sponsor materials
Sports apparel presents a particularly interesting circularity challenge.
The Ellen MacArthur Foundation’s article on creating a circular economy for sports kit highlights the scale of material waste across sports — from football shirts and trainers to tennis balls, wetsuits and bike inner tubes. It argues that sports needs to move beyond the linear “make, use, dispose” model towards keeping products and materials in use through maintenance, reuse, resale and refurbishment.
The opportunity includes:
- Repair and reuse to extend product life
- Collection and donation for secondary use
- Upcycling into new products
- Closed-loop recycling into new fibres
- Open-loop recycling into products such as insulation or rags
This can also become a commercial opportunity.
Instead of discounting or destroying outdated merchandise, sports organisations can turn surplus products into limited-edition products, upcycled merchandise or new fan experiences.
The result is not simply less waste.
It can mean new products, new revenue and stronger fan engagement.
Temporary event materials are another hidden resource
Major sporting events frequently create temporary infrastructure:
- Signage
- Branding
- Sponsor activations
- Flooring
- Hospitality installations
- Furniture
- Tents
- Barriers
- Displays
The problem isn’t necessarily the material.
It is often the business model around the material.
If something is designed to be used once, it becomes waste.
If it is designed to be stored, reused, rented, resold or donated, it becomes an asset.
The waste research provided for this article highlights temporary event materials as a significant opportunity because they can be planned for reuse, storage, donation or resale rather than treated as disposable event overlay.
This is the fundamental shift from linear to circular thinking:
Don’t ask: “How do we dispose of this?”
Ask: “Who could use this next?”
Zero waste is also a data challenge
One of the biggest barriers to progress is not technology.
It is data.
Many sports organisations cannot accurately answer:
How much waste did we generate last season?
What percentage was actually diverted?
Which waste stream costs us the most?
Which materials could generate revenue?
Reliable waste data creates the foundation for improvement.
It establishes the baseline, makes targets measurable, supports ESG reporting and strengthens certification applications.
And it allows organisations to demonstrate progress to sponsors, investors, fans and other stakeholders.
The research behind this article identifies limited data and accountability as a major implementation gap in sports waste management.
From zero waste target to zero waste business case
A successful zero waste strategy should therefore answer four questions:
1. What are we throwing away?
AUDIT.
Measure the waste streams, volumes, contamination and destinations.
2. What can we change?
ENABLE.
Identify operational, procurement and infrastructure changes that reduce waste and support ESG requirements and certification.
3. Who needs to be involved?
ENGAGE.
Work with suppliers, caterers, staff, cleaning teams, sponsors, athletes and fans.
4. Where is the value?
EARN.
Identify opportunities to reduce disposal costs, increase material value, reuse assets, generate revenue and create social impact.
This is the thinking behind WeGoZero’s Zero Waste 360° Sports Impact™ programme.
Beyond compliance: becoming a zero waste pioneer
Zero waste should not be approached simply as another ESG obligation.
For sports organisations, it can become a competitive advantage.
Imagine being able to say:
“We are the first certified Zero Waste Stadium in our country.”
That is not just a sustainability metric.
It is a story.
It can differentiate a venue from competitors, strengthen relationships with sponsors, provide new content for fans, support sustainability ratings and create a visible leadership position.
The PreZero Arena and TSG Hoffenheim demonstrated the potential of this first-mover strategy in Germany. The arena became the first certified Zero Waste stadium in the Bundesliga in 2023 and subsequently achieved silver certification.
The project itself began with extensive analysis of waste, data and ideas — illustrating an important point: certification is the outcome of a transformation, not the starting point.
But the opportunity extends far beyond football.
The same model can apply to:
- Football stadiums
- Rugby stadiums
- Basketball arenas
- Tennis venues
- Golf events
- Racing circuits
- Motorsport venues
- Concert and entertainment venues
- Multi-purpose arenas
- Mega-sporting events
And for most countries, the race to become the first is still open.
Zero waste, ESG and certification
Zero waste also sits within a broader shift in how events and sports organisations manage sustainability.
ISO 20121:2024, the international standard for event sustainability management systems, provides a framework for integrating environmental, social and economic considerations into event planning and delivery. It applies to events of all types and sizes and includes pathways for demonstrating conformity, including third-party certification.
For sports organisations, this reinforces an important principle:
Waste cannot be treated as an isolated operational issue.
It needs to be integrated into planning, procurement, supplier management, stakeholder engagement, operational controls, measurement and continuous improvement.
This is consistent with the broader direction of research into circular sports events, which calls for a move from conventional waste management towards more integrated circular systems.
The future of sports sustainability is circular
The sports industry has an extraordinary platform.
Millions of people watch.
Millions attend.
Sponsors invest.
Brands compete for visibility.
And every match, race and tournament creates a concentrated opportunity to demonstrate a different way of operating.
Zero waste can therefore become more than a back-of-house sustainability programme.
It can become part of the venue’s identity and business model.
The strongest sports organisations will not simply ask how to reduce their environmental footprint.
They will ask:
How can we create more value with fewer resources?
That is the essence of circular sports.
And the opportunity is already here.
