Most restaurant chains talk about sustainability in their marketing. Some actually compost their food waste at scale. The two categories don’t overlap as much as customer-facing branding suggests — but a handful of chains have built real composting programs that divert meaningful tons of food waste from landfill across hundreds or thousands of locations.

This is a look at eight chains running notable composting programs in 2026 — what each actually does, where the program is rolled out, how they measure success, and what makes each model distinct. The list emphasizes programs that have operated for years at substantial scale, not green-washing pilots or single-location experiments.
1. Chipotle Mexican Grill
Chipotle has run one of the most consistent national-scale composting programs in fast-casual dining, dating back to roughly 2010. The program operates across approximately 3,500+ locations company-wide, with location-level participation depending on local composting hauler availability.
What they compost: Food prep waste (vegetable trim, citrus peels, cilantro stems), post-consumer leftovers from compostable serviceware, used compostable bowls, napkins, and utensils.
Service materials: Chipotle uses fiber-based compostable bowls (since around 2018, the standard burrito bowl is bagasse or PLA-lined paper) and BPI-certified compostable cutlery. The packaging is engineered to compost in commercial facilities.
Measurement: Chipotle publishes sustainability reporting that includes pounds of food waste diverted to composting. Recent reporting indicates 50-70 million pounds annually company-wide diverted to composting and biodigestion.
Where it works: Locations in cities with established commercial composting hauler infrastructure (San Francisco, Seattle, Portland, parts of NYC, Boulder, Denver, parts of Texas urban areas). Smaller-market locations often lack the infrastructure to participate.
Operational notes: Back-of-house composting is mature. Post-consumer composting is harder because customers often dispose of bowls in the wrong bin. Chipotle has experimented with simplified bin signage and color-coding to improve diversion rates.
2. Panera Bread
Panera operates a substantial composting program at company-owned cafes and is rolling it out to franchisees. The program emphasizes both food waste from prep and waste from customer-facing operations.
What they compost: Coffee grounds (a major volume input), bread end-pieces, leftover pastries, salad trim, used compostable cups and bowls.
Coffee grounds specifically: Panera makes large quantities of brewed coffee daily. The spent grounds are a major composting input — by some estimates, the chain generates 100-300 pounds of spent coffee grounds per location per week.
Bread donation and composting: Panera’s Day-End Dough Donation program donates unsold baked goods to local food banks each evening. Items that can’t be donated go to compost rather than trash.
Where it works: Most company-owned cafes in major metros participate. The franchise system is slower to adopt due to capital costs of compost infrastructure setup at individual locations.
Customer-facing materials: Panera has shifted to compostable cups and packaging in recent years, though the rollout is uneven across the system.
3. Sweetgreen
Sweetgreen, the salad-focused chain, runs one of the highest-density composting programs in the fast-casual segment. The chain emphasizes that essentially everything served can be composted.
What they compost: Vegetable prep trim, leftover ingredients at end of day, bowls and utensils from customer service, coffee grounds, napkins.
Service materials: Sweetgreen’s bowls and utensils are designed to be commercially compostable. The bowls in particular are a major design element — a Sweetgreen meal in its bowl is intended to fully compost as a single unit.
Locations: Roughly 200+ locations across 13-15 US markets. Composting is enabled where local infrastructure exists, which is most major-metro Sweetgreen markets.
Reporting: Sweetgreen publishes detailed annual sustainability reports including composting data. Recent reports indicate 60-80% diversion rate from landfill across the company-wide system.
Operational notes: Sweetgreen built composting into the operating model from early company days. Newer locations include composting infrastructure as part of the standard build-out specification.
4. Just Salad
A smaller chain (~75 locations primarily in NYC, NJ, CT, and several other markets) with an unusually integrated composting program. Just Salad runs a closed-loop system where compostable customer bowls go back to a partnered composting facility.
What they compost: All customer bowls, utensils, napkins, and food trim.
Notable detail — the reusable bowl program: Just Salad has a parallel reusable-bowl program where customers can pay a small deposit ($2-5) for a reusable bowl that gets washed and reused. The chain reports the reusable program has avoided millions of single-use bowls since launch.
Composting for non-reusable: For customers who use compostable rather than reusable bowls, the chain runs commercial composting service through partnered haulers in their markets.
Reporting: Just Salad publishes sustainability metrics including specific bowl counts and composting diversion. Their model is replicable in smaller-chain operations.
5. Cava Mediterranean
Cava operates around 350+ locations across the US, with a steadily expanding composting program. The chain is later to mature on sustainability than some competitors but has been investing meaningfully since around 2020.
What they compost: Food prep trim, compostable bowls and utensils, napkins.
Service materials: Cava bowls are typically PLA-lined paper or molded fiber — both commercially compostable.
Where it works: Major metro locations in cities with municipal commercial composting. Smaller-market locations often lack the hauler infrastructure.
Notable detail: Cava emphasizes Mediterranean diet ingredients that include vegetable-heavy dishes; vegetable prep trim is a major composting input.
6. Pret A Manger
Pret operates over 500 locations globally, with composting programs varying by region. UK and major US locations have the most mature programs.
What they compost: Sandwich trim (a major volume input from the chain’s sandwich-prep operations), coffee grounds, customer-facing compostable cups and packaging, food waste.
Bread and sandwich trim: Pret produces enormous quantities of sandwich trim daily — the ends of baguettes and breads, herb stem trim, lettuce trim. This is among the largest single composting inputs in the chain.
Composting partnerships: In the UK, Pret has partnered with Bio-bean (a company that converts spent coffee grounds into biofuel and biochar) for coffee-grounds processing. The coffee-grounds-to-biofuel pipeline is a distinctive Pret approach.
Customer-facing materials: Pret has been one of the more proactive fast-casual chains on compostable cups and packaging in customer-facing operations.
7. Sweetfin
A smaller California-based chain (50-100 locations) specializing in poke and grain bowls. Strong composting program reflecting California composting infrastructure.
What they compost: Fish trim, vegetable prep trim, rice waste, customer bowls and utensils, coffee grounds.
Service materials: Bowls are commercially compostable; utensils are bamboo or wooden.
Where it works: California locations benefit from established commercial composting infrastructure. Out-of-state locations have varying composting access.
Notable detail: Fish trim composting is unusual at the chain scale — most chains avoid composting animal protein due to smell and pest concerns. Sweetfin manages this through sealed transport containers and dedicated composting hauler service that handles protein-inclusive food waste.
8. Tender Greens
A California-based chain (now expanded to other states) emphasizing locally-sourced California ingredients. The chain runs composting programs at most California locations and is rolling out to other markets.
What they compost: All food prep trim, customer-facing compostable packaging, napkins, coffee grounds.
Source verification: Tender Greens emphasizes that composting completes the food cycle for ingredients that came from local farms. Some farms that supply Tender Greens receive finished compost back as a soil amendment — a notable closed-loop relationship.
Reporting: Tender Greens publishes annual sustainability data including composting diversion rates.
Operational notes: The chain’s smaller size relative to Chipotle or Cava enables more direct relationships with local composting haulers and farms. The closed-loop farm-to-table-to-compost-to-farm model is more replicable at chain scale than is sometimes assumed.
Lessons Worth Extracting
Looking across these eight chains, a few patterns emerge for operators considering composting programs:
Infrastructure matters more than ambition. The single biggest factor determining whether a chain’s composting program works is whether commercial composting infrastructure exists in the operating market. Even ambitious chains can’t compost in cities without composting haulers. This is the primary constraint.
Bowl design enables success. Chains with thoughtfully designed compostable bowls (Sweetgreen, Cava, Just Salad) have higher diversion rates than chains that rely on customers to disassemble multi-material packaging. Single-material compostable serviceware is more reliable than mixed-material packaging.
Prep waste is a bigger lever than post-consumer. Most chain composting diversion comes from back-of-house prep waste (vegetable trim, coffee grounds, bread ends) rather than customer-facing waste. Operators thinking about starting composting should consider prep-waste capture first as the higher-impact, lower-friction entry point.
Coffee grounds are universal. Across coffee-serving chains, spent grounds are one of the largest single composting inputs. A chain selling coffee that doesn’t compost grounds is leaving substantial diversion on the table.
Reporting drives improvement. Chains that publish detailed composting metrics tend to improve over time; chains that make vague sustainability claims tend not to. Public reporting creates internal accountability.
Customer-facing diversion has limits. Even Sweetgreen and Just Salad — among the highest-diversion chains in the segment — achieve roughly 60-80% diversion in markets where infrastructure exists. The 20-40% gap reflects customer disposal behavior at end of meal, mixed-material packaging that confuses sorting, and disposal in mixed bins that contaminate the compost stream. Improvement beyond 80% diversion requires either reusable systems (Just Salad’s bowl program) or dramatically simplified packaging.
Closed-loop farm relationships are achievable. Several chains (Tender Greens, some Sweetgreen locations) have built relationships where finished compost from their operations goes back to farms supplying the chain. This adds a small additional sustainability claim that resonates with customers but requires logistical investment.
What’s Missing from This List
A few notable omissions worth flagging:
McDonald’s. Operates some composting in international markets and pilot programs in select US markets but does not run a meaningful chain-wide composting program at the US franchise level.
Starbucks. Despite extensive sustainability marketing, the chain-wide composting program is in development and not yet at the diversion rates of operations on this list. Coffee-grounds composting is more developed than other waste streams.
Subway. Limited composting at the chain level. Some franchisees operate composting programs locally; not chain-wide.
Wendy’s, Burger King, KFC, Taco Bell. Limited public reporting on composting programs at substantial scale.
The absence from this list doesn’t mean these chains do no composting — many have pilot programs or location-level composting — but their programs are not yet at the scale of the eight chains listed above.
Final Thoughts
A working composting program at chain scale requires three things: infrastructure (composting haulers and facilities in the operating market), service-material design (single-material compostable packaging where possible), and operational discipline (staff training, bin signage, prep-waste capture systems).
Chains that have invested in all three over multiple years have built programs that divert millions of pounds annually. Chains that have invested in one or two have built programs that work in pockets but not chain-wide. Chains that have invested in none typically claim sustainability without meaningful composting diversion.
For operators starting composting programs at smaller scale (5-50 locations), studying the operating details of these eight chains — particularly Just Salad and Sweetfin, both at smaller scale than the larger chains — provides workable models. The infrastructure constraints are real; the operational patterns are achievable; the diversion outcomes are measurable.
The restaurant industry collectively generates a substantial portion of US food waste — roughly 22 billion pounds per year. Chain composting programs are not yet at the scale that solves the food-waste problem, but they’re demonstrating that substantial diversion is feasible at scale. The expansion path runs through both more chains adopting and more cities building the composting infrastructure that makes adoption possible.
