I think you should donate them, reuse is better than recycling!

Environmentally speaking, the best thing to do is donate them so that someone else can use them.

Alternately, you could use them to store stuff in your house -- craft supplies, nuts and bolts, etc.

Shelters use these to handout food.

If you're switching away from them because they're unsafe for you to use, is it really that great to donate them to someone else who will eat off them?

If you can donate them somewhere that will use them for non-food use, that's great. But recycling might be better than giving someone else the cancer you didn't want.

i also think an animal shelter would be great. if they use them for pet food it not like the dog is really going to get and die from cancer before they were going to naturally pass anyways.

Also a daycare center might use them for their kids crafts. they don't save food at daycare centers so they can't use them for food.

i would say to try using them in your house for non-food items. bathroom supplies, art supplies, paper and doo-dads.

we poke holes in some of them for bath and sand toys and all those itty bitty animals that are constantly underfoot.

The tops can go under plant pots, and the bottoms can be used to organize your drawers. I use those and ice-cube trays to sort my earrings, necklaces and bracelets!

If you have a little tool storage area, you could use these to hold nails, tacks, rubber bands, etc.

Or, if you're a paint chip hoarder like I am, dedicate a container per color (blues, greens, etc.) to corral them.

Other storage uses: coins, poker chips, miscellaneous hair stuff (clips, bobby pins), bandages and other small bathroom/first-aid stuff.

In your vanity: eyeshadow, lipsticks, etc.
