Zero-Waste Catering: What It Looks Like in Practice

"Zero-waste" has followed a familiar trajectory. A term that once meant something specific — a measurable operational commitment to diverting materials from landfill — has gradually become marketing shorthand, applied to products and services with varying degrees of seriousness. In the events industry, where a single evening can generate hundreds of pounds of waste, it is a claim worth scrutinizing.

We use the term, and we want to be precise about what we mean by it. What follows is an account of what actually happens at a Purslane event, from the food on the plate to the last bag of compost leaving the venue.

Why the Events Industry Has a Waste Problem

Food waste accounts for roughly 10% of global greenhouse gas emissions and makes up nearly a quarter of all materials sent to U.S. landfills and incinerators. The events industry is a meaningful contributor to both figures: a single large-scale gala or wedding generates significant quantities of food waste, single-use packaging, and materials that, without deliberate intervention, go directly to landfill. Most of this happens invisibly, after guests have left and the event has been declared a success.

The standard catering model wasn't designed with any of this in mind. It was designed for convenience and margin, which is why single-use plastic is so prevalent, why surplus food tends to be discarded, and why composting at events remains the exception rather than the rule. Changing that requires operational decisions that cost more and take more planning — which is why most caterers don't make them.

What Happens Before the Event: Sourcing

Zero-waste begins before we arrive at your venue. The majority of our ingredients come from farms and producers within 200 miles of New York City — Satur Farms, Norwich Meadows Farm, Stokes Farm, Go Fish Co. in North Bergen, and others — through supply chains that are shorter, more transparent, and less carbon-intensive than those of industrial distributors. We know how our food is grown, which means we can ask questions about soil management, inputs, and labor practices that a purchase order to a national distributor can't answer.

We work with vendors who share our commitment to sustainable, local, and regenerative food production, and we prioritize women- and minority-owned businesses in our procurement. These aren't aspirational commitments — they're part of how we build our menus and select our suppliers each season.

What Happens During the Event: On-Site Waste Management

At every Purslane event, we handle all composting and recycling on-site. This is not something we outsource to the venue or leave to guests to manage — it is part of our service, staffed and executed by our team. Compost collection receptacles are set up as part of our standard event infrastructure. Every food scrap, every compostable container, every appropriate material is sorted and diverted from landfill before we leave the building.

We partner with a local composting facility that processes our organic waste into nutrient-rich compost, keeping it out of landfills entirely. For materials that can't be processed through standard municipal recycling — specialty items that would otherwise go to waste — we work with Terracycle, which recycles materials most programs won't touch.

Nothing about this requires any effort from you or your guests. It happens in the background, as a standard operational component of every event we produce.

What Happens to the Packaging: Plastic-Free by Design

For our drop-off and delivery service, we've eliminated single-use, non-compostable plastics entirely. Through our partnership with noissue, every container, plate, and utensil we use is compostable and made from renewable resources with no harmful additives — no microplastic contamination in your food, no packaging that will persist in the environment for centuries after your event. This applies to every drop-off order, regardless of size, as a standard feature of the service rather than an upgrade.

For full-service events, all tableware is either reusable or certified compostable. We don't use plastic wrap, styrofoam, or conventional single-use plastics anywhere in our operation.

What Happens to Surplus Food: CHiPS

Some food waste is inevitable in catering — the nature of producing food at scale for a fluctuating headcount means that not everything gets eaten. What matters is what happens next. Surplus ingredients and prepared food that don't meet our presentation standards are donated to CHiPS, a food pantry in Park Slope that has been serving our community since 1971. This keeps usable food out of landfill and in the hands of people who need it.

What Happens to the Carbon: Zero Foodprint

On-site waste management addresses what happens to materials. Carbon offsetting addresses the emissions embedded in everything that led up to the event — the growing, the processing, the transportation, the energy used in preparation. Through our partnership with Zero Foodprint, we offset the carbon impact of our entire business, including our supply chain. We invest in regenerative agriculture and carbon capture projects across the United States and globally to ensure that our operations net out at zero.

This is what Scope 3 certification means: not just our direct emissions, but the full footprint of everything we do. It is the most comprehensive form of carbon accounting available, and it is why we can describe ourselves as carbon-neutral with specificity rather than approximation.

What Official Documentation Looks Like: TRUE for Events

For clients who need to demonstrate their event's sustainability profile — nonprofits with environmental commitments, corporations with ESG reporting requirements, couples who want their wedding to be genuinely rather than nominally green — we can facilitate TRUE for Events certification. Key members of our team are trained TRUE Advisors, qualified to help events achieve certification and providing official, third-party verified documentation of zero-waste status. This gives you something concrete to report, rather than a caterer's self-assessment.

What This Means If You're Planning an Event

You don't need to think about any of this on the day of your event. You don't need to brief your guests, set up a recycling station, or coordinate with a composting service. The zero-waste infrastructure is built into how we work — the planning, the sourcing, the on-site logistics, and the documentation all happen as part of producing your event, not as additions to it.
