America’s schools throw out $5 million in food every day. Here’s what one school manager did to tackle the problem — and feed the hungry.

The red plum’s presence confounds the third grader. She didn’t want the fruit in the first place, yet there it is. She doesn’t want to eat it, but she knows that tossing it into the garbage at Oakland’s Hoover Elementary School is wrong. Standing before containers for trash, recyclables, compostables, and unopened entrees, milk cartons, and whole fruit, the girl’s decision-making matches her Disney-movie hijab — Frozen.

Fortunately, Nancy Deming, the school district’s sustainability manager for custodial and nutritional services, is supervising the sorting line today. “If you’ve started eating your fruit, it goes in the compost,” she reminds the girl with a smile. “If you haven’t taken a bite, it goes to Food Share.” The girl glances at the plum, then carefully places it in the clear bin, from which students can take whatever unopened or unbitten foods they please.
