Step one

Remove the peel from an orange (we used Citrus Sinensis Navel Oranges from Florida). While the peel is still fresh, blend it into small granules. The size of the granules can affect the characteristics of the end material.

Step two

In a bowl, combine the Hemp Protein Powder, Gluten, and granulated Orange Peel. Mix the ingredients together until they become evenly distributed. The mixture should resemble a light brown powder with visible orange specs. Set this bowl aside.

Step three

In a separate bowl, stir together the water and vinegar. The water and vinegar should be at room temperature before they are combined.

Step four

Incorporate the chitosan into the water/ vinegar solution in small parts. Be sure to add the chitosan slowly while constantly mixing so that the chitosan can dissolve evenly into the solution.

Step five


Slowly add the chitosan/vinegar/water solution into the bowl containing Hemp Protein Powder/ Gluten/ Orange peel.  Bring the mixture together with a silicone spatula as the solution is added. Switch to hand kneading the material if the Chitosan and the gluten become too sticky for the spatula. Stop mixing when the material resembles a brown dough like consistency.

Step six

Press the material into a mold or onto a cooking sheet. Place in the oven at 200F until dry or leave the mixture to air dry for a few days.

Step seven

As part of a biodesign research group, we reimagined where waste products could be used. This material looks to live harmoniously with the lifetime of product use, so by using all natural ingredients, it biodegrades sooner rather than later.  This also creates a collaboration between different industries and people as the ingredients are usually discarded. Essentially building a material to create with nature. Through this material, we were able to build strong vessels that can be sanded, oiled, and shaped through molding or high power tools such as the bandsaw and drill.
