On the surface it seems like an eco-friendly alternative to petroleum-based plastics, but I've heard that it can absorb substances that are stored in it, and become unsanitary. Is this true?
as far as i know there is a so ya based plastic that is environmental friendly
The question is safe for WHAT? Plastics are used in millions of applications.. we already have many different types of plastics (PVC, nylon, ABS, polyProplyene, polyethylene, etc.) Can soy plastics be used as an alternative to one or more different types? Or in a portion of the millions of uses?? So, given your thoughts that it absorbs substances and can become unsanitary.. how about applications that are less demanding? Safe for car seats, non-food items, etc.. yes.. Food storage .. maybe not.. In fact, many of the plastics used by Ford Motor Company in its first cars (Model T and Model A) were soy based plastics. However, the world moved away from soy plastics because they are (or were) more expensive when petroleum plastics came into common use.
