These materials are being used in ways that we don't normally think about. Imagine taking these techniques and applying them to other waste streams to help people gain awareness.
I like the idea of permanently diverting waste from land fills very much. I think that most non recyclable/non compostable material will still end up in a land fill at the end of it's useful upcycled lifespan and in the meantime is likely to contaminate the landscape with it's tiny particles of plastic residue.
I do this myself...I buy blinds at the thrift store and use them to write on and mark plants. They are back to being 'trash' when I'm done with them.
I used to have others save one quart yogurt containers for my plants for market...once I found out that this actually makes them trash rather than something that can be recycled I stopped.
On the other hand, I love the idea of upcycling natural materials from thrift stores. An all wool or cotton rug is compostable with time.
I guess I worry that any awareness many folks would gain from upcycling non recyclables would have to do with how cute that Clorox bottle doll looked (for example) and not thoughts of using less plastic.
