About Polylactic Acid

Polylactic acid (PLA) is a biodegradable and renewable thermoplastic polyester derived from lactic acid, which is produced by fermenting plant-based materials such as corn starch or sugarcane. PLA has similar mechanical properties to PET plastic but is more environmentally friendly as it requires 65% less energy to produce and emits 68% fewer greenhouse gases. It was first synthesised in the 1930s, but its commercial production began in the 1990s. Today, it is widely used in medical devices, food packaging, 3D printing, and other applications.

Properties of Polylactic Acid

Polylactic acid’s specific gravity ranges from 1.24 to 1.30, and it exhibits a melting temperature between 140°C and 210°C. PLA has a glass transition temperature of 50°C to 75°C, indicating its rigidity and brittleness at room temperature. The tensile strength typically measures around 59 MPa, while the elongation at break is approximately 6-10%. PLA's crystallinity varies from 5% to 35%, influencing its mechanical and thermal behaviour significantly.

Manufacturing Process of Polylactic Acid

The production process of polylactic acid (PLA) begins with the preparation of feedstock, which typically consists of renewable resources such as corn and sugarcane. The feedstock undergoes hydrolysis to produce dextrose or other sugars. These sugars are then fermented using specific bacteria to produce lactic acid.

The next step involves the purification of the lactic acid, where it is separated and purified from the fermentation broth using methods such as filtration and evaporation. The purified lactic acid then undergoes esterification to form lactide, which is subsequently polymerised in a reactor. The lactide is distilled to remove any remaining impurities before undergoing ring-opening polymerisation to produce PLA. Next, the PLA is cooled and cut into pellets for easier handling and processing.

Synthesis of Polylactic Acid (PLA)

The production of PLA involves several steps, such as:

Step 1: Fermentation to Produce Lactic Acid (C3H6O3)

The first step in the production of PLA is the fermentation of carbohydrates (e.g., glucose) to produce lactic acid. This process is typically carried out by bacteria such as Lactobacillus.

Chemical Reaction: C6H12O6 (aq) → 2C3H6O3 (aq)

Step 2: Purification of Lactic Acid

The crude lactic acid obtained from fermentation is purified through processes such as filtration, precipitation, and distillation to remove impurities and obtain high-purity lactic acid.

Step 3: Polymerisation to Produce Polylactic Acid (PLA)

The purified lactic acid is polymerised to produce polylactic acid. There are two main methods of polymerisation: direct condensation polymerisation and ring-opening polymerisation of lactide.

In direct condensation polymerisation, lactic acid monomers undergo a condensation reaction to form PLA, releasing water as a byproduct.

Chemical Reaction: nC3H6O3 (lactic acid) → (C3H4O2)n (PLA) + nH2O

In ring-opening polymerisation, lactic acid is first converted to lactide, a cyclic dimer of lactic acid. The lactide is then polymerised to form PLA.

Chemical Reaction: 2C3H6O3 (lactic acid) → C6H8O4 (lactide) + H2O

nC6H8O4 (lactide) → (C3H4O2)n (PLA)

Applications and Drivers of Polylactic Acid

Applications of PLA span various industries, including medical (e.g., sutures and bone fixation devices), packaging (e.g., food containers and films), additive manufacturing (3D printing), and consumer goods (e.g., disposable cutlery and cups) due to its eco-friendly properties and safety for food contact. The growth in the PLA market is driven by increasing environmental awareness, consumer demand for sustainable products, and government policies promoting biodegradable materials.
