Lactic Acid and Polylactic Acid: A Green Revolution in Bioplastics


Chicago, Jan. 23, 2024 (GLOBE NEWSWIRE) -- Lactic acid is a type of organic acid that belongs to the alpha hydroxy acid (AHA) family. It is a colorless, water-soluble liquid that occurs naturally in various foods like sour milk, yogurt, and some fruits. Lactic acid is also produced in the human body during the process of anaerobic metabolism, particularly in muscles during intense exercise. Polylactic acid (PLA) is a biodegradable and bioactive thermoplastic made from renewable resources, often derived from plant-based sources such as corn starch or sugarcane. PLA is considered an eco-friendly alternative to traditional petroleum-based plastics. The production of PLA involves the polymerization of lactic acid molecules. The lactic acid market is estimated at USD 1.6 billion in 2023 and is projected to reach USD 2.8 billion by 2028, at a CAGR of 12.4% from 2023 to 2028. The global polylactic acid market is anticipated to be valued at USD 1.3 billion in 2023 and escalate to USD 2.9 billion in 2028 by growing at a CAGR of 17.7%
