Schools try to keep cafeteria trash from piling up

LAUREL, Md. — As students walk by with their lasagna, snacks and fruit, Sally Oswald sees a cafeteria routine that most parents do not. This is no lunch line. It's a trash line.

Students at Hammond Elementary toss away half-eaten apples, untouched sandwiches and portions of pizza slices. That's on top of the packaging, from shiny juice pouches to plastic bags.

Even on Wednesdays, when the school encourages "waste-free" meals, lunchtime yields about 100 pounds of trash. Students weigh the trash to check each grade's progress in reducing waste, but the numbers go up and down like signs of a struggling diet.

"When you think that this happens in every elementary school every day, it starts to speak to you," Oswald said, looking at the weekly trash tallies. "This is a real problem."

In scattered communities across the country, schools are working to keep their cafeterias from becoming trash heaps. Whether driven to help the environment, save money or stop a careless tossing of food, some educators say they are hungry to make lunch more efficient.

The mission isn't easy. Many parents favor throwaway packaging that's quick and easy, right down to pre-wrapped peanut-butter sandwiches. Students have their own reasons for leaving things behind — some feel too rushed to finish meals during brief lunch periods, some don't like the food, some don't think to reuse those sealable bags.

It adds up. A single student produces 45 to 90 pounds of garbage a year in disposable lunches, according to New York's Department of Environmental Conservation. A federal review of the National School Lunch Program found that wasted food costs more than $600 million, plus an untold nutritional loss.

At Oak Hills Elementary in Ventura County, Calif., students filled eight barrels a day with lunch waste just a few years ago. Principal Anthony Wright was appalled to find most of it was water bottles, plastic bags and paper products that could be recycled.

So he enforced zero waste tolerance. Students, under the watchful eye of peer monitors, divided their trash into waste and recycling bins. Parents were strongly encouraged to eschew conveniently packaged foods in favor of reusable containers. Before long, the waste was down to about one barrel a day.
