Team 10 Investigates - Are your recyclable plastic bags ending up in landfills? 

Team 10 deployed plastic bag bundles at the Target in Eastlake and Mission Valley, as well as the Walmart store on College Avenue in San Diego on Februay 21.
The teams spent months monitoring each tracker’s location multiple times a day and researched each location on the way, to ask if any type of metal detection to sort plastic bags was used.
The tracking device in the Eastlake Target never pinged outside of the store. The one in Mission Valley last tracked to the landfill in Santee, and the one from Walmart last pinged to the Miramar landfill.
In all, ABC News and its affiliates launched 46 trackers.
