80 CONCESSIONS May | June 2026 AirportImprovement.com SEA Webb and his team also provide on-site training sessions and meet with tenant management to answer questions or clarify points of confusion. “We’re here to support them every step of the way,” he says. Like employee training, waste audits are also ongoing. “This will give us a clearer picture of how much we compost and identify areas where we can improve,” Webb notes. One Step Further? Currently, SEA only requires reusable serviceware at sit-down restaurants that have dishwashing infrastructure. But the airport has explored the option of adding a central dishwashing system to support reusable serviceware for takeout providers as well. “We’ve had conversations with vendors who provide this service, but there are logistical challenges,” Webb shares. “Our concessions are spread across a large area, so we’d need a system to collect the items, a dedicated dishwashing facility on site, and a process for restocking and storing inventory. There are also point-of-sale system integration and deposit system issues to work through. It’s a pretty significant logistical puzzle to work out.” Sustainability Leaders Moore sees Sip, Savor, Sustain as an important part of a larger strategy to advance airport sustainability nationwide and across the continent. “SEA loves being in the forefront of things,” she says. “We want to be the most sustainable airport in North America. We want what we do to help other airports become more sustainable, too.” Her advice to other airports that are considering similar programs? Plan ahead and give tenants time to acclimate to the change. Webb recommends verifying there is a composter nearby that can accept compostable packaging. “If you don’t have that, there’s not much you can do,” he laments. “The next step is to start conversations with concessionaires and lounges to learn what kind of access they have to compostables currently and what they may need.” Finally, Webb emphasizes the need for follow-up and support: “You can’t just set rules and turn them loose. You need to be with them every step, answering their questions, supporting their needs, and responding to their waiver requests. If you do those things, you will have a successful program.” For travelers passing through SEA, the impact of changes to waste disposal may seem small. But every compostable cup, reusable plate and carefully sorted waste bin is another step toward a more sustainable future. New waste collection stations have separate bins for compost material, recycling and trash.
