A major US stadium holds 70,000 to 90,000 fans for a Saturday football game or a Sunday NFL matchup. That’s a small city’s worth of people, in one place, for three to four hours, all drinking beer, soda, water, and Bloody Marys out of cups. By kickoff in the third quarter, you can stand at any concourse trash-bin and watch waste accumulate at about the rate of a dump truck filling up.

For decades, the standard stadium cup was a clear or printed PET (polyethylene terephthalate) cup — the same material as a Coca-Cola bottle, sturdy, recyclable in theory, mostly trashed in practice. A 90,000-seat venue running a full football season would push 4-5 million PET cups through its trash stream every year. Almost none of them made it back into the recycling system, partly because of beer and soda residue, partly because PET sorting wasn’t worth it for the recyclers, partly because the cups got compacted with food waste and napkins into one big landfill-bound bag.
In the last decade, several major US stadiums have switched all their beverage service to compostable PLA (polylactic acid) cups. The biggest names doing this at scale: Mercedes-Benz Stadium in Atlanta, Levi’s Stadium in Santa Clara, the Coliseum in Oakland (before the Athletics moved), Lincoln Financial Field in Philadelphia for certain operations, Empower Field at Mile High in Denver for select concourses, Lumen Field in Seattle, and a handful of others. Each has a slightly different approach, but the pattern is similar enough to describe what a “compostable cup program at a 90,000-seat venue” actually looks like.
This is what one of those programs looks like in practice — the supply chain, the bin setup, the workforce, the diversion math, and the real-world friction.
Mercedes-Benz Stadium: the headline case
Atlanta’s Mercedes-Benz Stadium opened in 2017 and is the highest-profile sustainability-first venue in major US sports. It’s LEED Platinum certified — the highest LEED tier — and the first NFL stadium to reach Platinum status. The sustainability program covers solar, water reclamation, electric vehicle charging, and food service.
The compostable cup program is part of the food and beverage side. Every soda, beer, water, and cocktail served in the stadium (except in some premium suites with glassware) goes into a certified compostable PLA cup. The cup is clear with the Mercedes-Benz Stadium logo printed on it; sourced from Eco-Products and World Centric in various sizes and configurations.
By the numbers: Mercedes-Benz Stadium serves roughly 2 million cups per NFL season across 8 home games at ~71,000 capacity, plus playoffs and special events. Add MLS Atlanta United matches (3-4 million more cups across their season), college football events, and concerts, and the total annual cup volume runs 5-6 million units. Every one of them is supposed to end up in a compost bin.
The bin setup on the concourse is the visible side. Three-bin stations every 50 feet or so, color-coded — green for compost, blue for recycling, black for trash. Staff in green vests walk the concourses to remind fans and help them sort. The cups, plates, napkins, and food scraps all go in compost. The bottles, cans, and plastic-coated condiment containers go in recycling or trash.
The composting is processed by a regional commercial composter — Atlanta has multiple commercial-scale facilities — and the finished compost goes to local farms and landscape projects. The stadium reports diversion rates in the 70-80% range for game days, meaning 70-80% of total waste generated does not go to landfill. That’s a remarkable number for a venue of this scale.
Levi’s Stadium: the West Coast model
Levi’s Stadium in Santa Clara, California, has been running a similar program since opening in 2014. Capacity is 68,500 for football, expandable to 75,000 for special events. The 49ers, college football, concerts, and major events bring the annual cup volume to roughly 3-4 million units per year.
The stadium uses PLA-based cups sourced from regional suppliers. The composting happens at a commercial facility in Northern California — the Bay Area has the densest commercial composting infrastructure in the country, with multiple facilities in San Francisco, Oakland, and the Central Valley accepting commercial loads.
Levi’s reported in 2018-2019 that they were achieving roughly 75% landfill diversion on game days, with food and beverage service generating about 60% of that diversion. The stadium has been honest about the challenges — even with good bin setup and green-vest staff, contamination rates run 15-25% (compost bins with plastic in them, recycling bins with food in them). The cleanest streams require post-collection sorting, which adds labor cost.
What it takes to run the program
Behind the scenes, a compostable cup program at a 90,000-seat venue requires a few specific operational elements that don’t exist at smaller venues.
Supply chain. A 90,000-seat stadium needs reliable supply of millions of compostable cups per year, across multiple sizes (12oz, 16oz, 20oz, 32oz souvenir cups), in custom-printed configurations. Major suppliers — Eco-Products, World Centric, Vegware — have institutional sales teams dedicated to large venue accounts. Lead times for custom-printed orders run 8-12 weeks. The cost is roughly 20-40% higher than equivalent PET cups in 2024-2025 institutional pricing, though the gap has narrowed as PLA production has scaled.
Bins and signage. Three-bin stations every 50-80 feet across concourses. Each station costs $400-800 capital. A 90,000-seat stadium might have 200-300 stations across multiple concourse levels, suite levels, and back-of-house — total capital investment in the millions for full conversion.
Workforce. Green-vest “sustainability ambassadors” or “ECO captains” walking the concourses during games. A major venue might deploy 30-60 of these workers per game, paid hourly. Annual labor cost: roughly $50,000-150,000 per season depending on game count and wage rates.
Hauling and composting partnership. A regional commercial composter has to be willing to accept stadium-sourced compost loads, with the contamination levels typical of public-event composting (15-25%). Not all composters will. Stadiums in areas without large commercial composters (most of the South, Midwest, and parts of the Mountain West) can’t run a true closed-loop program; their “compostable” cups end up in the trash regardless of labeling.
Concession partner buy-in. Stadium food and beverage is often run by third-party concessionaires (Aramark, Sodexo, Delaware North, Levy Restaurants). Switching to compostable cups requires concessionaire cooperation — they’re the ones buying the cups, training their workers, and pricing the beverages. Without F&B partner alignment, no cup program works.
The contamination problem
The dirty secret of stadium compost programs is contamination. Even with green-vest staff and clear signage, fans put the wrong things in the wrong bins. A fan finishes a cup of beer at halftime, sees a green bin, drops in the cup — but also tosses in the plastic-foil ketchup packet, the foil-wrapped hot dog wrapper, the plastic straw, and the napkin all in one motion. The compost bin now has plastic in it.
Stadium operators report contamination rates of 15-25% in compost bins under normal conditions, sometimes higher for big games with rowdier crowds. The commercial composter has to either accept the contamination (with sorting at the facility) or charge higher tipping fees, or refuse the load entirely.
The mitigation tactics are partial:
- Educational signage with images. “PLA cup → compost. Plastic bottle → recycle. Foil wrapper → trash.” Visual cues work better than text.
- Bin opening shapes. Some venues use shaped openings — a round hole for cans, a slit for cups, a rectangle for trash — to make wrong-bin choices physically harder.
- Ambassador prompts. Green-vest staff actively redirect fans who are about to make wrong-bin choices.
- Post-event sorting. A second pass at the dumpster, where waste crews pull out gross contamination before composter pickup.
Even with all these, getting under 10% contamination has been hard for any large venue. The realistic target is 15-20%, with the expectation that the composter handles the rest.
The cup itself
The cup that’s making this all possible is the PLA-based stadium cup. The technical specifications:
- Material: Polylactic acid (PLA), a bioplastic derived from corn or sugarcane starch
- Compostability: ASTM D6400 and BPI-certified for commercial composting
- Temperature tolerance: Up to 105-110°F for cold use; not suitable for hot beverages without lining
- Heat-sealable lid compatibility: Most stadium cups designed for snap-on or push-through lids
- Print compatibility: Accepts flexographic and offset printing for stadium logos and sponsor placement
Major suppliers in the institutional space include:
- Eco-Products (Boulder, Colorado): The “GreenStripe” line is the most-recognizable institutional compostable cup. Cup wall has a distinctive green band for fan recognition. Used at multiple NFL stadiums, college venues, and major events.
- World Centric (Petaluma, California): Comparable product line with B-Corp certification. Custom printing available. Used at Levi’s Stadium and other West Coast venues.
- Vegware (Edinburgh, Scotland): UK and increasingly global supplier; used at some US venues.
- NatureWorks Ingeo: The underlying PLA resin producer for many of these cups (Cargill subsidiary). Major resin volume increase since 2020.
PLA’s environmental footprint: produced from corn or sugarcane, which is a renewable feedstock; manufacturing requires less petroleum than equivalent PET; end-of-life compostable in commercial facilities. The lifecycle impact studies vary, but typical results show 20-50% lower carbon footprint than PET when full lifecycle (including end-of-life composting) is counted.
The honest critique: PLA isn’t a perfect material. It requires industrial composting (60-65°C for 60-90 days) to fully break down; it does not biodegrade in landfill, in marine environments, or in cold backyard piles. Without the commercial composter at the end, PLA in the trash is effectively as inert as PET. The cup is only as compostable as the infrastructure it lands in.
What’s behind the trend
Why are major venues making this change? A few drivers:
ESG and sustainability reporting. Major sports franchises now report on environmental impact under shareholder and league pressure. Compostable cup programs are visible, quantifiable, and marketable.
City regulations. Some major US cities (San Francisco, Seattle, Berkeley, parts of Massachusetts) have ordinances banning or restricting single-use plastics in public venues. Compostable PLA is one of the allowed alternatives.
Fan expectations. Particularly among younger fans, sustainability programs are part of the venue’s brand. Visible green programs improve attendee satisfaction.
Cost convergence. PLA cups used to cost 3x equivalent plastics. By 2024-2025, the premium is 20-40% — significant but no longer prohibitive at scale, especially when paired with reduced landfill tipping fees.
Major league commitments. The NFL, MLB, NBA, and NHL all have league-level sustainability programs encouraging member venues to reduce single-use plastics. The 2026 World Cup, with matches in the US, has compostable supply commitments built into venue contracts.
For B2B operators in the institutional and venue space — concessionaires, supply distributors, event organizers — institutional-volume compostable cups, plates, and utensils are increasingly available. Our compostable cups and straws and compostable food containers lines include venue-grade options with BPI certification and high-volume case configurations.
What it doesn’t solve
Compostable cup programs don’t solve the broader problem of stadium waste. A big game still generates hundreds of tons of trash — uneaten food, plastic-coated napkins, foil wrappers, plastic ketchup packets, plastic straws (even when the cup is compostable), packaging from concessions, and the various non-cup items. The cup itself is one item in a complex waste stream.
A few items still go in the trash because they can’t be composted or recycled at scale: plastic-foil condiment packets, plastic-coated paper trays, mixed-material napkin holders, gum and candy wrappers. These represent maybe 10-15% of total stadium waste, depending on the venue. A “zero waste” stadium claim almost always has caveats about what gets counted.
The honest assessment from the operators running these programs: they’re meaningfully better than the alternative, but they’re not perfect. A 70-80% diversion rate is a major improvement over the 5-10% diversion rate of a conventional plastic-cup stadium, but it’s not zero waste.
A 90,000-seat stadium switching the cup
If you stand at a Mercedes-Benz Stadium concourse on a Saturday night in October, watching a beer vendor pour Sweetwater 420 into a clear PLA cup with the Falcons logo, you’re seeing the visible end of a supply chain that runs from a NatureWorks plant in Nebraska, to a manufacturer like Eco-Products in Boulder, to a printing partner, to a distribution warehouse in Georgia, to the stadium’s food service operation, to the fan’s hand, to the green bin on the concourse, to the dumpster behind the kitchen, to a commercial composter in metro Atlanta, to a soil amendment at a local farm.
That sequence didn’t exist a decade ago. It exists now because of a coordinated effort across material producers, manufacturers, venue operators, concessionaires, haulers, composters, and fans. The cup is the visible piece, but the infrastructure behind it is the actual achievement.
The compostable cup used in 90,000-seat venues is, in some sense, the most ordinary product imaginable — a plastic-looking cup that holds beer for three hours. But the supply chain it travels through, and the system it ends up in, represents a small piece of what the future of stadium operations might look like: closed-loop, low-impact, and quietly working in the background while the game plays out.
