CAMDEN, N.J. — A boy’s lost cellphone ended up in a New Jersey garbage dump and survived.

Ethan Roncace’s phone got thrown away at a high school in Haddon Township on Monday.

His father, Craig, tells WCAU-TV in Philadelphia he used an app to track the phone and saw it was on the move. The signal led the family to the Covanta waste-to-energy facility in Camden.

He suited up and started digging through a mountain of trash. He recovered the phone in 30 minutes and it still worked.

Workers were close to dumping the trash into a 50-foot-high and 25-foot deep pile of garbage.

Covanta’s Rich Harrington says there’s a little better than 50 percent success rate when they can identify the trash truck.
