PLA Depolymerization
report_problem Problem Statement
Polylactic acid (PLA) was promoted as the biodegradable solution to plastic pollution, but in practice, PLA only degrades in industrial composting facilities operating above 58C — conditions unavailable to 95% of the global population. PLA contaminates PET recycling streams (it's visually identical), fails to decompose in landfills, oceans, or home compost, and there is currently no economically viable chemical recycling pathway to recover the lactic acid monomer for repolymerization into virgin-quality PLA.
trending_up Market Size
$1.2B global PLA market (growing 18% CAGR, recycling infrastructure gap widening)
gavel Regulatory Drivers
EU Packaging and Packaging Waste Regulation (PPWR) mandates recycled content targets for plastic packaging. EU Circular Economy Action Plan prioritizes chemical recycling technologies. California SB 54 requires 65% reduction in single-use plastic waste by 2032. EPR schemes penalize non-recyclable plastics. ISO 15270 (Plastics — Guidelines for the recovery and recycling of plastics waste). Industrial composting certifications (EN 13432, ASTM D6400) don't address chemical recyclability.

No enterprise interest recorded yet. Companies can indicate their volume and urgency to help guide research priorities.
flag Success Criteria
CAGE-catalyzed reaction achieves lactic acid yield above 50% (mass of lactic acid recovered / theoretical maximum from PLA hydrolysis) — significantly higher than water-only control. Demonstrate clear catalytic effect: catalyst reaction yield at least 2x the water-only control. L-lactic acid enantiomeric excess above 95% (measured by optical rotation or chiral HPLC). Reaction conditions: below 150C, atmospheric or near-atmospheric pressure preferred, aqueous medium, no concentrated acids/bases.
precision_manufacturing Equipment Needed
Pressure-rated reaction vessels (Parr reactor, autoclave, or pressure tubes rated to 150C/5 bar), oil bath or heating mantle with temperature controller, PLA pellets (commercial grade, known molecular weight), analytical balance (0.001g), vacuum filtration setup, HPLC system (for lactic acid quantification) or polarimeter, pH meter, 0.1M NaOH solution, deionized water, timer, thermometer, face shield, heat-resistant gloves
