Lactic Acid

Lactic acid is an organic acid that occurs naturally in the body, especially during anaerobic metabolism (e.g., muscle fatigue). It is also produced by bacteria and used widely in various industries, such as food, pharmaceuticals, and cosmetics.

• Sources: Lactic acid is primarily produced via fermentation of carbohydrates (like glucose or sucrose) by lactic acid bacteria or yeast.

• Applications: It is used in food preservation (as a preservative), as a flavoring agent, and in the production of biodegradable plastics like PLA.

• Biodegradability: Lactic acid is biodegradable and can be used in creating more environmentally friendly materials compared to petroleum-based plastics.

Poly Lactic Acid (PLA)

PLA is a biodegradable plastic made from renewable resources, such as corn starch or sugarcane. It is created through the polymerization of lactic acid.

• Production Process: PLA is made by polymerizing lactic acid into long chains (polymers). This process can be achieved through either direct polycondensation or ring-opening polymerization.

• Properties: PLA is transparent, has a low melting temperature, and is compostable. It is often used for packaging, disposable cutlery, medical implants, and fibers.

• Environmental Impact: PLA is considered an environmentally friendly alternative to petroleum-based plastics. Since it is made from renewable sources, it can reduce carbon footprint. However, PLA still requires industrial composting facilities for proper degradation, as it does not break down efficiently in typical landfill conditions.

Key Differences Between Lactic Acid and PLA

• Chemical Nature: Lactic acid is a single molecule (monomer), while PLA is a polymer made up of repeated lactic acid units.

• Function: Lactic acid is used in various industries as an ingredient or chemical intermediate, while PLA is specifically used as a biodegradable plastic.

• Degradation: PLA, as a polymer, is designed to break down more slowly in the environment than lactic acid itself.
