home-made bioplastic badge idea

I like the idea that there could be a kind of homemade plastic that is so HUSP-y that it would even please Paul.  As HUSPy as piney tar.  Yet is still functional as plastic.  

Maybe it hasn't been invented yet, but if someone can invent it then they get the badge.

It has all the criteria set out, all the standards, and they're impossible to meet then no one ever gets that badge, but if someone figures it out then they get it.

Functions plastic serves us...waterproofing, planters, water-tight planters, carrying water, stacking shelves...jugs with handles for No. 1 Golden Formula Nitrogen Fertilizer...making really easy-to-spot tools that are bright orange in the green grass. . .etc.  

Milk plastic seems pretty strong contender, from what I've read. Vinegar, milk, heat.  Wow.

Maybe you get the straw-level plastic badge if you grew or raised all the ingredients yourselves and even grew the firewood?

Other things I see on the market:

--starch-made forks etc.
--bamboo
--hemp

how much processing?

I tried to make milk plastic, it didn't take.  I think I needed to heat the milk hotter, will try again perhaps at some point.
