Portland-based GO Box, a service that provides and cleans reusable take-out boxes for local food trucks.

PORTLAND, OR – With nearly 700 food carts licensed last year, Portland, Ore., is arguable a leader in the mobile food revolution. Lucky residents can choose between Iraqi-Jewish sabich, yeasted Belgian liegewaffles, or Indonesian rendang, all served out of a friendly window on the sidewalk. But all of these mobile meals come with a downside — namely, trash.

According to some estimates, food carts dispose of roughly 60,000 containers every month in downtown Portland alone. Some are compostable, some recycleable (though not through Portland’s current curbside program), but regardless, city officials say most end up in the garbage. And green-minded “cartivores” who want to bring their own containers are prevented from doing so by the city’s health code.

As we’ve reported, food waste is a giant worldwide mess, but there are many folks taking action on a local scale. Last year, a new Portland company, GO Box, cropped up with a solution to the mountain of clamshell packages. Participating carts stock GO Box’s reusable containers, which are made of a blue-tinted #5 plastic, like a more durable version of the standards takeout clamshell.

Once containers are used, they are collected at drop-off sites and then professionally cleaned (satisfying our protective friends at the health department). Eaters sign up for a $12 annual membership fee, and each time they drop off a dirty tray, they get a token to exchange for a clean one the next time they dine at a participating cart.

Currently about 50 carts participate, along with a handful of restaurants and vendors at the stadium that hosts Portland’s soccer team. They pay a nominal fee for each GO Box used (partially offset by the savings on disposables), and receive an incentive for each new member they sign up (as well as the positive publicity from signing onto the program).

Founder Laura Weiss has a background in environmental policy, and has been growing GO Box since last summer. IT now boasts about 1,000 subscribers, with more signing up every month. Weiss has been working out the logistics as they scale up — figuring out how to locate and staff collection sites, signing restaurants up to volunteer dishwashing services, figuring out a route of bicycle-based deliveries and collections — but she says her biggest mission is just getting people to think differently.

“It’s a whole new idea people have to wrap their minds around — we don’t need to have disposables,” she says. Although closed systems like this have existed for years in cafeterias and hospitals, people are just starting to realize that, with a little coordination, a similar practice can take hold among independent cart businesses.
