Toni, maybe you could offer items to a local school for recycling crafts? (Only because plastic yogurt containers can't yet be sold as antiques or collectibles! But someone had foresight when they saved coffee cans with keys, tin tobacco containers, etc.)
Somewhere along the line, I have read about someone who collects junk on their property and makes things from discards, maybe in the state of Washington or Oregon? Possible source would probably be one of Mary Randolph Carter's Junk books -- American Junk, Big City Junk, Garden Junk, Kitchen Junk and most likely of the four American Junk or Garden Junk. I don't recall seeing the others in my local library.
The ME Home Companion magazine and books often show items that were refurbished, also different artists who utilize discards in their creations.
My sister has ornaments for her Christmas tree made from patchwork-look material. It happens this past year I was given a pair of curtains, very faded in spots, made of this same material. So those could be repurposed into ornaments, and the faded parts could go toward one of Pat's literal rag-mops!
Magazine or calendar pictures could be made into envelopes with a template, providing unique stationery.
Who among us has not used an envelope to make a list? Backs of already-printed-on computer papers for other printing.
String from pet food packages and bird feathers found outside could combine with wire hangar or other wire and beads to make Ojo de Dios -- Eye of God? That might not be the correct term, but there is a term for a good luck charm.
Some scrapbooking supplies could become doll accessories -- cookie cutters, game pieces, tiny envelopes and file folders.
Foil chip or other bags can be run through a special cutter and used as package ties -- read about it but haven't done it yet.
Those opaque wax paper bags from cereal might become window shades in a dolls house or diorama. (Does paint adhere to that?)
Newspaper into papier mache anything.
To name a few ideas.
