Poly Lactic Acid (PLA)

Poly Lactic Acid (PLA):Recently, Balrampur Chini Mills launched India’s first industrial-scale PLA plant aimed at promoting eco-friendly alternatives to single-use plastics.

• About PLA: A bioplastic made from plant starches(corn starch, tapioca roots, and sugarcane) through ring-opening polymerization.

o It is a thermoplastic polyester commonly used in medical devices, food packaging, injection molding, and 3D printing.

o Biodegradable under suitable conditions, breaking down into non-toxic lactic acid.

o Typically translucent or transparent but can be pigmented to produce various colors based on application needs.

• What is a Polymer and Polymerization: The term polymer refers to a large molecule composed of repeating structural units, typically with a high molecular mass (ranging from 10³ to 10⁷ u).

o These large molecules, also known as macromolecules, are formed when many smaller units called monomers join together through covalent bonds.

o The process by which monomers chemically combine to form a polymer is known as polymerization. The monomers involved are usually simple, reactive molecules that repeat in a chain to build the larger polymer structure.
