PET Hydrolysis Catalyst
report_problem Problem Statement
PET (polyethylene terephthalate) is the world's most common plastic for bottles and food packaging, with over 70 million tonnes produced annually. Despite being the most recyclable plastic, only 30% of PET is actually recycled, and mechanical recycling degrades polymer quality with each cycle. Chemical recycling via hydrolysis or glycolysis can recover virgin-quality monomers (terephthalic acid and ethylene glycol), but current processes require extreme temperatures (250-300C), high pressures, and concentrated acids or bases — making them energy-intensive and uneconomical compared to virgin PET production.

gavel Regulatory Drivers
EU PPWR mandates 25% recycled content in PET bottles by 2025, 30% by 2030. California SB 54 recycled content requirements. EU Single-Use Plastics Directive bottle collection targets (90% by 2029). Extended Producer Responsibility (EPR) fees incentivize recyclable design. ISO 15270 plastics recovery guidelines. Coca-Cola, PepsiCo, Unilever pledges for 50-100% recycled PET. European Plastics Pact. Ellen MacArthur Foundation Global Commitment.

flag Success Criteria
CAGE-catalyzed PET hydrolysis achieves conversion above 30% at 200C (vs. <10% for water-only control). TPA recovery yield above 20% of theoretical. TPA purity confirmed by melting point (>295C) and FTIR match to reference standard. Demonstrate clear catalytic enhancement: minimum 3x conversion improvement over thermal-only control at same temperature. Long-term target: achieve equivalent conversion at 50C lower temperature than uncatalyzed reaction.
