Substitute for Styrofoam Cups?

I am requesting the name and address of a hemp business that can produce a hemp/fiber composite material to be used as a replacement for styrofoam cups used in vending machines. Please provide the name, address, phone # and any URL of such a hemp product producer who could fabricate such an item. Also,where can I contact a producer of hemp/sisal natural fiber board. I’m interested in having 12, 16, and 24 oz. insulated cups to replace the styrofoam used today. An environmentally friendly, bio-degradeable product. Thank you.
