The U.S. recycled PET (rPET) flakes market, valued at USD 2.04 billion in 2024, is projected to grow at a CAGR of 8.2% from 2025 to 2034, with national policy impact, R&D leadership, and strategic positioning shaping the trajectory of both domestic and global players.

Its influence is amplified by robust local manufacturing bases, federal and state-level incentives, and integration into global supply chains. Leadi
