New Formulation

This corn plastic was made using a new formulation created during year 3 of experimentation. The plastic is far more durable and does not crack

Plastic Molding

Molding done during the first year of experimentation. The plastics cracked and were almost gelatin like, unable to keep their shape

Avocado Plastic

Plastic derived from the avocado seed. One major issue with this plastic is the starch extraction. Ground seed particles often mix with the starch, creating lumps in the plastic.
