Technology for Polymerisation Grade Lactic Acid Production
At kasel group, we specialize in developing and engineering advanced processes for producing polymerisation grade lactic acid – the essential feedstock for polylactic acid (PLA), one of the most widely used biodegradable and bio-based polymers. Our technology enables high-purity output, cost efficiency, and scalable solutions for clients seeking to enter or expand within the sustainable plastics market.
Why Polymerisation Grade Lactic Acid Matters
• Critical for PLA Properties: PLA’s strength, clarity, and biodegradability depend on the purity and stereochemistry of the lactic acid feedstock. Lactic acid occurs in two enantiomers:
o L-lactic acid ((S)-lactic acid)
o D-lactic acid ((R)-lactic acid)
The ratio of these enantiomers directly influences the thermal and mechanical properties of the final PLA polymer.
• Strict Quality Standards: Even trace impurities or optical inconsistencies can affect polymerisation efficiency and degrade PLA performance.
• Rapidly Growing Market: With rising demand for sustainable materials, high-quality PLA and lactic acid production technologies are increasingly in demand worldwide.
