Do Native Americans still use all parts of their food?

I was at an art show this weekend, and there was a Native American vendor who was selling dreamcatchers. The frame of the dreamcatcher was made out of yogurt containers and the webbing was made out of the cellophane from the front of pasta boxes. This got me wondering, do Native Americans still believe is using "all parts of the kill"? Like, do they use the plastic wrap on their meat to make gloves and stuff?
