thanks, alex

Answer 1

I found a link to plastic from corn starch but I know it say potato but when you read the instructions you can use corn starch instead.

Bonus it also gives a lot of the science behind it so it should help you out for your project.

Answer 2

I don't think it is possible.

Corn starch has little tensile strength.

The bags you saw in Europe were made here in th U.S.A. years ago. They are a blend of plastics and corn starch.

They degrade more rapidly when buried in land fills. There is a problem with that.

The rapid degradation releases the toxins created by the degradation of plastics at a far more rapid pace and the potential damage to the environment is WORSE as a result.
