Major catering and foodservice companies operate at scale that backyard composters can barely imagine. Compass Group serves over 5 billion meals per year. Aramark and Sodexo each run thousands of foodservice locations across hospitals, universities, corporate cafeterias, and event venues. The food waste these companies generate is staggering — and the composting programs they’ve built (or haven’t built) shape how a meaningful share of all institutional food waste gets handled.

The companies with strong composting programs operate at a scale where even modest improvements move tons of waste per location per year. Their programs are also instructive for smaller operators because they’ve already worked out most of the operational kinks — the hauler relationships, the staff training, the contamination management, the customer-facing communication. A neighborhood caterer or a small university dining service can borrow heavily from what these companies have figured out at scale.
This is a survey of six major caterers with notable composting programs, what they actually do, and what smaller operators can learn from them. Specific program details rotate as companies update their sustainability commitments, so treat the specifics here as a snapshot rather than current state — but the underlying patterns are stable.
Bon Appétit Management Company
Bon Appétit, owned by Compass Group but operated as a distinct brand, is consistently cited as one of the most ambitious foodservice sustainability programs. They operate roughly 1,000 cafes across corporate, university, and museum accounts in the US.
What they do: Bon Appétit has had a comprehensive food waste reduction program (Imperfectly Delicious Produce, since 2014) and composting programs at most accounts. They’ve been publicly committed to composting since the late 2000s — early enough that they helped develop hauler infrastructure in many of their markets.
Notable elements:
– Public reporting on food waste and recovery rates
– Source reduction emphasized alongside composting (using “ugly” produce, repurposing trim into stocks, etc.)
– Account-level data tracking
– Composting programs tailored to each account’s local infrastructure
The lesson for smaller operators: Source reduction first, composting second. The companies with the best programs don’t just compost more efficiently — they generate less waste in the first place. The Imperfectly Delicious approach (use the ugly produce, use the trim, plan portions carefully) is replicable at any scale.
Compass Group
Compass Group is the largest foodservice company in the world, operating thousands of accounts globally. Their sustainability commitment cascades down to subsidiary brands (Bon Appétit, Eurest, Restaurant Associates, others).
What they do: Compass has multi-decade waste reduction commitments, with composting as a core element. They’ve publicly committed to substantial waste diversion across their account portfolio. The commitments translate to procurement-level changes — Compass-managed accounts often get composting programs as part of standard operating procedure rather than as account-specific initiatives.
Notable elements:
– Scale enables hauler relationships that smaller operators can’t access
– Procurement specifications include compostable foodware standards across the portfolio
– Internal sustainability reporting feeds into broader corporate ESG disclosures
– Multi-year reduction targets reviewed and updated regularly
The lesson: Cascading sustainability commitments from corporate down to operations work when there’s accountability and procurement-level enforcement. A mid-sized catering operation can adopt similar internal cascades — corporate sustainability policy → procurement specifications → operations standards → measurement.
Aramark
Aramark is roughly comparable to Compass in scale, with substantial concentration in higher education, healthcare, and corporate dining.
What they do: Aramark publishes annual sustainability reports detailing waste diversion progress across their accounts. They’ve had composting programs at substantial portions of their accounts for years; recent reports show continued expansion.
Notable elements:
– “Be Well. Do Well.” sustainability platform integrates food waste and composting alongside other ESG areas
– Strong presence at universities, where composting programs are relatively common
– Corporate-level food waste reduction goals translate to account-level KPIs
The lesson: Sustainability platforms (named, branded, multi-criteria programs) make sustainability work more discoverable for customers and more accountable for the company. Even small caterers can name their sustainability program and use the name internally and externally as a coordinating mechanism.
Sodexo
Sodexo is the third-largest of the global foodservice companies, with strong presence in education, healthcare, and corporate dining.
What they do: Sodexo’s “WasteWatch” program, developed with technology partners, tracks food waste at account level using kitchen-side measurement systems. The data feeds back to chefs and managers for daily and weekly adjustments. Composting programs operate alongside the source-reduction work.
Notable elements:
– Technology-enabled waste tracking (smart scales, computer vision, etc.) provides granular data
– Source reduction prioritized through measurement-and-feedback loops
– Public reporting on waste reduction
– Multi-year reduction targets
The lesson: What gets measured gets managed. Modern food waste tracking technology has gotten cheap enough that even small operations can deploy basic versions. The information loop (kitchen waste data → chef adjustments → reduced future waste) is more impactful than aspirational commitments alone.
Restaurant Associates
Restaurant Associates is the upscale catering and corporate dining brand within Compass Group, operating high-profile accounts including museums, art galleries, and corporate headquarters at premium price points.
What they do: Composting programs across most accounts, often tied to broader sustainability messaging that fits the upscale brand positioning. Reuse of food trim and source reduction practices that reduce waste before it reaches the compost stream.
Notable elements:
– Premium account positioning supports premium-priced compostable foodware where used
– Customer-facing sustainability narrative integrated with brand
– Sustainable sourcing and food waste reduction work in parallel
– Some accounts have on-site composting; others use commercial haulers
The lesson: Premium-positioned accounts can absorb compostable foodware costs and benefit from the customer-facing sustainability narrative. Premium pricing creates room for sustainability investments that more cost-pressured segments can’t easily make. Smaller premium-positioned caterers can apply the same logic.
Guckenheimer
Guckenheimer is a smaller but notable corporate dining specialist, often cited for sustainability leadership in the segment. They focus on tech and life-sciences corporate accounts in major markets.
What they do: Comprehensive sustainability program with composting as a core element. Their accounts tend to be in markets with mature composting infrastructure (Bay Area, Seattle, etc.), which makes the programs more impactful than equivalent programs in markets without infrastructure.
Notable elements:
– Geographic concentration in markets with composting infrastructure
– Corporate accounts that themselves prioritize sustainability (tech companies)
– Detailed account-level reporting
– Integration of sustainability into menu development, sourcing, and operations
The lesson: Geographic and customer-segment alignment matters. A composting program in a market with mature infrastructure for clients who value sustainability has stronger ROI than the same program for customers who don’t care in markets without infrastructure. Match the program ambition to the market and customer reality.
What These Programs Have In Common
Looking across the six, common elements emerge:
Multi-year commitment. None of these programs were stood up in a single quarter. They’ve been built over 5-15 years with sustained investment and gradual scaling.
Source reduction emphasized. All of them treat composting as a step in the waste hierarchy, not the goal. Reducing waste at the source (better menu planning, using trim, accurate portion forecasting) gets attention alongside composting infrastructure.
Public reporting. The companies with the strongest programs publish data — annual sustainability reports, ESG disclosures, account-level metrics. The reporting creates accountability and enables external comparison.
Procurement integration. Sustainability commitments translate to procurement specifications. Compostable foodware procurement, supplier sustainability requirements, sourcing standards — all built into how the company buys things, not just into how they market.
Account-level execution. The corporate commitment doesn’t accomplish anything if individual account managers don’t implement it. The strong programs have account-level training, monitoring, and accountability that make the commitment operational.
Geographic awareness. Programs scale faster in markets with mature composting infrastructure. The companies recognize this and target program expansion accordingly.
What Smaller Operators Can Take From This
The major caterers operate at scale that allows things smaller operators can’t easily replicate (hauler relationships, technology investment, reporting infrastructure). But several practices translate down:
Build a multi-year roadmap. Rather than one-off composting initiatives, plan a 3-5 year program with milestones. Commitment compounds; year-by-year improvement adds up.
Measure what’s actually happening. Even basic kitchen-side waste tracking (a scale and a notepad) feeds the source-reduction loop that produces real impact.
Source reduction before composting. Compost what’s left after you’ve reduced. Don’t lead with composting infrastructure if you haven’t done the menu and prep work.
Public reporting at appropriate scale. A small caterer’s sustainability summary doesn’t need to be a 50-page ESG report, but a one-page annual update on what was diverted, what was reduced, and what the goals are creates accountability and customer-facing brand value.
Procurement specifications. Write down what you commit to buying — BPI-certified foodware, locally-sourced X% of menu, etc. — and hold suppliers to it.
Pick markets with infrastructure. A small caterer expanding will get better ROI from sustainability investments in markets with mature composting (and customers who care) than in markets without.
Name the program. “Our composting program” is fine; “Imperfectly Delicious” or equivalent named brand is better. Names create coordination internally and recognition externally.
What Falls Short
Worth being honest about what the major caterer programs don’t always do well.
Customer-facing communication varies. Some accounts get strong sustainability signage and customer messaging; others get the same composting program with minimal customer-facing communication. The brand value from composting works only if customers know.
Geographic gaps. Programs in markets without local composting infrastructure either don’t exist or rely on long-distance hauling that compromises the environmental case. Several major caterers operate in markets where their composting program is essentially trash hauling at higher cost.
Contamination challenges remain. Account-level sorting discipline varies. Even strong corporate programs report ongoing contamination issues that limit what facilities can accept.
Aspirational goals outpace operational change. Several major foodservice companies have committed to ambitious 2030 or 2050 reduction targets. Year-by-year progress against these targets is sometimes underwhelming. The aspirational commitment is louder than the operational change.
These limitations don’t undermine the value of the programs — they’re still substantially better than non-programs — but the honest framing matters when smaller operators try to learn from the leaders.
Worth Knowing About: Notable University Programs
Beyond the corporate caterers, several university foodservice operations run notable composting programs worth examining for ideas:
UC Berkeley dining services — pioneered campus composting programs in the early 2000s; comprehensive infrastructure today. Strong public reporting on diversion rates.
Cornell University — substantial on-campus composting capacity; integrated with agricultural research programs.
Oberlin College — early adopter of zero-waste dining concepts; small-scale but instructive.
University of California system — system-wide commitments translated to consistent practice across campuses, with results varying by campus.
Yale University — comprehensive food waste reduction and composting program with public metrics.
University programs are often more accessible to read about than corporate programs because the universities publish detailed reports and case studies as part of their educational mission. For smaller operators looking for case studies that aren’t filtered through corporate marketing, university dining services are a richer source of practical detail than corporate sustainability reports.
The Industry Direction
The major caterers are not standing still. Their programs continue to expand, deepen, and integrate with broader corporate sustainability commitments. As composting infrastructure expands in more markets, their programs follow. As measurement technology improves, their tracking gets more granular. As customer demand for sustainability grows, their programs become more visible in marketing.
For smaller operators, the implication is that the bar keeps rising. What was sustainability leadership in 2015 (a basic composting program at flagship locations) is sustainability table stakes in 2025. Operators who haven’t built composting programs yet are increasingly behind their competitors. The major caterers’ direction of travel is the direction the industry is going.
The good news for smaller operators is that the playbook is increasingly public. The case studies, the operational details, the metrics that matter — all are documented in major-caterer sustainability reports and case studies. A small catering operation can read these reports and adapt the relevant practices without having to invent the program from scratch.
The composting programs at major catering companies are simultaneously a window into what’s possible at scale, a benchmark for industry direction, and a free playbook for smaller operators ready to do the work. Reading the reports and borrowing the practices that fit your scale is one of the easier sustainability moves available to any catering operator who hasn’t started yet.
Background on the underlying standards: ASTM D6400 defines the U.S. industrial-compost performance bar, EN 13432 harmonises the EU equivalent, and the FTC Green Guides govern how “compostable” can be marketed on packaging in the United States.
