If you've got a stack of playing cards that are beat up or missing a few cards, you might be tempted to toss the whole deck into the recycling bin. But you shouldn't, and here's why: They aren't recyclable. Even though they feel like regular paper stock, playing cards are coated with a thin sheet of plastic to give them durability. This plastic makes them non-recyclable. Instead of contaminating a load of recyclables, throw them away in the trash, or upcycle them into a fun craft project.
