I would like to know more about the separation of those materials in order to recycle it. I know that there is this specific procedure but no data and info at all! Maybe I am looking in the wrong way please help!
I think your question is incomplete. What exactly are you trying to separate? What are you hoping to get as a product? Are you supposed to separate or grind to increase the surface area before recycling?
Maybe if you can provide this information, I may be of help because am knowledgeable in the production of biocomposites.
