Banana Peel Bioplastic
Reference
This project was developed by a 16-old Turkish student for the Google Science Faire.
 
Trial 1 - Diverging points from the original protocol
Trial performed at FoAM Brussels Biolab on September 22nd.
 4 banana peels on ripening degree 7 (rather than 4)
 
 Dried them in kitchen paper (instead of gauze)
 
 Washed the puree (rather than the banana peels) with a 1% (rather than 0.5%) sodium metabisulphite solution
 
 The color of the puree was dark yellow after blending.
 
 The color turned salmon after adding HCl
 
 The color turned dark olive green after adding NaOH (lessive de soude)
 
 Propane 1-2-3 triol was replaced by liquid glycerin from suppositories
 
 The proportions were 6 times higer than in the protocol
 
 Cooked 40 minutes in the random temperature gas oven of FoAM Brussels
 
Ended up as a black unstructure & cooked-puree like structure (not a plastic at all).
 
Trial 2
Trial performed at FoAM Brussels Biolab on September 24th.
