The Philadelphia prison system has snagged federal funding to start a composting program using food scraps leftover from the city's six prisons. And if prison food is anything like hospital or airplane grub, this program promises to be a smash success.

Prisons Commissioner Louis Giorla, Deputy Mayor for Public Safety Everett Gillison and Wayne Naylor, a deputy director with the U.S. EPA, are expected to announce details of the food-waste composting pilot program tomorrow at a news conference outside the Curran-Fromhold Correctional Facility.

As part of the program, inmates will learn how to compost, a job skill officials hope they can take home after they've served their time behind bars.
