MONTGOMERY COUNTRY, Md.—Luis Pozo’s lunch tray was the size of a notebook, a thin cardboard rectangle he used to carry his noon meal through the cafeteria of Francis Scott Key Middle School in Silver Spring.
The eighth-grader loaded it with chocolate milk, potato rounds, a burger and a fruit cup. When he was done, he stacked the tray onto a growing pile.
“They can be recycled,” Luis said. “If we don’t recycle, we’re going to destroy our planet.”
It was a sign of times to come in Montgomery County, as Maryland’s largest school system leaves behind the long era of the polystyrene lunch tray for a more environmentally friendly replacement that will be used to serve up nearly 15 million school meals a year.
