Not in any recycling program I have ever heard of. Sorry.
They're good for reusing, though! If the bag is not torn and hasn't had anything really oily or staining in it, rinse it out and hang it over a spatula or something in your dish drainer. We have used some probably 20 times! Once a church friend gave me some food left over from an event in a bag he'd brought, which was the heavy duty kind with an actual sliding tab zipper, and I thanked him for the bag as well as the food. He looked at me funny.
We had that bag for YEARS.
