Introduction to Biodegradable Plastic - Polylactic Acid

In recent years, there has been a growing concern about the environmental impact of traditional plastics and the need for more sustainable alternatives. One such alternative is biodegradable plastic, and polylactic acid (PLA) has emerged as a prominent player in this field. PLA is a biodegradable polymer derived from renewable resources, making it an eco-friendly choice for various applications.

Polylactic acid, commonly referred to as PLA, is a type of biodegradable plastic that stands out due to its unique properties. It is derived from plant-based materials, such as corn starch, sugarcane, or other biomass sources. This renewable origin sets it apart from conventional plastics, which primarily rely on fossil fuels. PLA offers several advantages, making it an attractive option for sustainable packaging, disposable products, and other applications.

PLA is produced through a process known as fermentation. The plant-based raw materials undergo several stages of conversion, beginning with the extraction of starch. This starch is broken down into simple sugars, which are then fermented by microorganisms to produce lactic acid. Through further processing and polymerization, lactic acid is transformed into PLA pellets, which can be shaped into various forms using standard plastic manufacturing techniques.
