PLA (Poly Lactic Acid) is a new developed eco-friendly material which is derived from plant-based starch.
Plant starch turns to be Glucose via Hydrolysis reaction. And then, Glucose further turns to be Lactide via Fermentation reaction. Combine these single Lactide to be Poly Lacitic Acid via Polymerization, we eventually get the raw material of this eco-friendly material, PLA.
We can make daily products from this PLA material via mold injection process. Once in composting conditions, the PLA products will composted and back to nature environment.
