Project Information
Material Qualities
Hard Matte, Most proeminent smell is of the added vinegar, rugous
Material Recipe
Xg avocado seed powder 2XmL water 0.1Xg xhantan gum 0.1XmL vinegar X = the desired amount of material to be processed.
Material Application
The material, since it is biodegradable and even edible, could be used for: -Packaging -Single-use cutlery -Single-use tableware Since the material is sourced from restaurant’s waste, I consider it would be interesting to have it back in the context of those spaces as objects as: -Menu support -Napkin holder -Candle holder -Lamp structure, etc
Material Method
There are mainly 3 steps on making the material: - grinding the seed - cooking - putting in a mold or 3D printing it.
-With dry seeds, first break them into small pieces (with a meat mallet for example) -Take the small pieces and put in a grinder to make it like a fine flour -With this flour, follow the recipe and add the correspondent amount of water and vinegar -Cook it in a medium temperature, until it becomes viscous -Take out from the heat and add the xanthan gum, mix it evenly. -Use this material to put in a mold or 3D print
Material Narrative
The material was sourced from restaurants that have avocado on their menu. The avocado seed is thrown away and the average waste from a Mexican restaurant in Barcelona is of 70 seeds daily. So, it is interesting to work with this material to shift the perception around what is waste. The final result was a biodegradable and an edible new material, mostly done with avocado seeds and the addition of water, a binder and an antibacterial ingredient.
It fits in the context of the circular economy by being fully biodegradable, with no sources of materials derived from petrol and also, being edible.
