Reuse in schools

Schools consume and dispose of billions of single-use foodware items annually and generate a lot of waste that is not easily recycled or composted. Reuse is the solution.

The USDA reports that 4.7 billion lunches are served annually in the National School Lunch Program.

Reusable foodware in K-12 schools used to be the norm. But between the commercialization and transformation of school lunch programs into a plastic-processed, heat-and-serve model of food service; changes in school infrastructure and budgets; and the Covid pandemic, single-use now dominates in many cafeterias across the US.

Not only are these single-use foodware items harmful for the planet, but commonly-used single-use products in school food services have been found to be laced with toxic and carcinogenic perfluorinated compounds, commonly referred to as PFAS.

Sustainability is a goal for many schools around the country. But all too often they focus on diversion from landfills — through better recycling and composting — rather than eliminating unnecessary waste in the first place. 

No matter if it is tossed, composted, or recycled, waste requires expensive sorting, hauling, and processing. And for the environment and your school budget, reuse beats single-use every time.

Let’s teach future generations to reuse instead of just recycle.

We didn’t want to normalize the idea that it’s okay to just use a dish for 15 minutes and then toss it in the trash

Going reusable saves schools money.

Whether a school’s food is prepared and served on-site; prepared off-site and delivered from a central commercial kitchen; or provided by contracted food management companies, or a combination of the above—there are cost-effective solutions to shift from single-use to reuse in cafeterias.

Reallocating school budgets from maintaining a costly take-make-waste operation in campus food services to a circular system of reuse for dine-in and grab-and-go will build efficiency that:

  • reduces waste, carbon emissions and plastic pollution

  • cuts costs

  • enhances the dining experience

  • offers a service that your school community enjoys and takes pride in

In fact, analysis of existing case studies of K-12 schools that switched to reuse reveals:

  • Schools saved an average of $23,6000 

  • Schools broke even financially often within a few months and no more than the second year into their reuse programs (depending on up-front costs)

We found we were able to start saving money within the second year of reuse because we weren’t constantly putting out funds to purchase something that literally goes in the trash can. The project became less cumbersome to our finances than it would have been had we stayed with our single-use products within about 19 months of undergoing this change to reusables.

Grants for replacing milk cartons with bulk milk

The ubiquitous  milk cartons found in school lunch rooms are generally not recyclable, and often milk carton waste (and discarded milk) is one of the largest sources of waste from school cafeterias. Schools are remedying this problem by installing bulk milk dispensers, and there are funding opportunities to help the transition: 

  • In 2025,  Zero Waste Washington secured a King County RE+ grant and began working with County schools to move from cartons of milk to bulk milk dispensers.

  • The Chef Ann Foundation offers funding to schools to switch to milk dispensers.

like this Green-Screen certified tray, can be designed with the cup holder in the middle of the tray, providing the most stable surface.

When it comes to dishwashing, schools have options

Many schools find it cost-prohibitive to install and/or maintain commercial dishwashers—or they do not have the space. The conversation does not need to end there! 

  • Contracts with a reuse service provider who can pick up, wash, and return dishware can replace expenditures on waste hauling and dishwasher installation or maintenance. This was the route Reaching All Minds Academy in Durham, NC took, and they broke even after 19 months. The Walpole, MA school district contract with reuse service provider Re:Dish involved no upfront costs and prevents 396,000 disposables from entering the waste stream annually. 

  • Grants can help pay for the up-front cost of reusables. California piloted a dishwasher grant in 2022, and Upstream’s reuse grant tracker lists possibilities for reuse funding across the US and Canada.

The role of schools in accelerating the reuse economy

As part of our mission to grow and support the reuse industry, Upstream is working on levers to attract capital to the reuse industry. Private capital strategies include targeting impact investors and connecting them with reuse startups transforming the stadiums and arenas of the Sports & Entertainment sector—a beachhead sector for reuse. If a reuse service provider working in Sports & Entertainment also services the local school district, they become an engine of a localized reuse economy, accelerating the ROI for investors.
