Production Process of PLA (Polylactic Acid)
1. Raw Material Sourcing:
Starch Extraction: Raw materials such as corn or sugarcane are harvested, and starch is extracted. For corn, this involves milling and enzymatic processes to convert starch into glucose.
2. Fermentation:
Lactic Acid Production: The glucose obtained from starch is fermented using specific microorganisms (usually Lactobacillus bacteria) to produce lactic acid. This fermentation process can take several hours to days.
3. Purification:
Lactic Acid Purification: The lactic acid produced is then purified to remove impurities and unreacted materials, ensuring high purity levels for further processing.
4. Polymerization:
Lactide Formation: The purified lactic acid is heated to form lactide, a cyclic dimer of lactic acid. This step often involves a condensation reaction where water is removed.
Ring-Opening Polymerization: The lactide is subjected to ring-opening polymerization in the presence of a catalyst to produce PLA. This process can occur in bulk, solution, or melt form.
5. Granulation:
Pellet Production: The resulting PLA is cooled and granulated into small pellets, making it easier to handle and process in subsequent manufacturing stages.
6. Processing:
Molding and Extrusion: The PLA pellets can be processed using techniques such as injection molding, extrusion, or 3D printing to create various products, including containers, films, and fibers.
7. Quality Control:
Testing: Finished PLA products undergo quality control tests to ensure they meet required specifications, including mechanical properties, biodegradability, and safety standards.
