Chemically recycled, bleach-compatible PET resin for sustainable packaging
Re-Du PET-OX™ is an innovative chemically recycled PET resin designed for bleach-compatible packaging. Utilizing a catalyst-driven depolymerization and re-polymerization process, this resin prevents chain scission and discoloration, maintaining recyclability and durability.
Overview
Re-Du PET-OX™ is a chemically recycled PET resin engineered specifically for bleach-compatible packaging solutions. This innovative material utilizes a unique catalyst-driven depolymerization process to break down waste PET into BHET monomers, which are then re-polymerized with oxidative-stabilizing co-monomers and phosphite/silane end-cappers. This molecular design effectively blocks NaOCl attack sites, preventing chain scission and discoloration while ensuring the resin remains fully recyclable in the PET stream. PET-OX™ is compatible with injection stretch blow molding, offering a sustainable, circular solution for durable chemical packaging.
Technical specifications
- Chemical Process: Depolymerization of waste PET into BHET monomers and re-polymerization with specific co-monomers and end-cappers.
- End-Capping: Phosphite/silane end-cappers block oxidation-sensitive sites.
- Compatibility: Works with existing PET recycling infrastructure and injection stretch blow molding.
- Performance: Maintains performance within 25-50% PCR (post-consumer recycled) blends.
- Testing: Accelerated bleach-exposure tests conducted to measure tensile strength, color stability, and molecular-weight retention.
- Recyclability: Validated under APR/EPBP standards, including tests for NIR sortability and regrind/reprocess viability.
Technology readiness level
Currently at TRL 2, PET-OX™ is in the early stages of development. Future validation plans include scaling up to kg-scale production and further testing to confirm performance and recyclability under industry standards.
About Re-Du Company
RE-DU is a recycling technology company that has developed a patented process for the chemical deconstruction of mixed plastic waste. By breaking down diverse plastic types—such as PET, PC, PU, and PA—into monomers, the company enables the transformation of previously difficult-to-recycle materials into commercially valuable chemical products. This technology eliminates the need for costly sorting of mixed waste streams and offers an efficient, cost-effective alternative to traditional plastic management systems, which often rely on outdated processes that fail to address the majority of global plastic waste.
By providing a scalable solution for chemical recycling, RE-DU aims to reduce reliance on fossil fuels and minimize the environmental impact of plastic pollution in landfills. The company serves as a partner for industries seeking sustainable chemical feedstocks and is contributing to the development of a circular economy. Supported by initiatives like the Innovation Crossroads Award and research collaboration with Oak Ridge National Laboratory, RE-DU is positioned to help transition toward a net-zero carbon society by proving that mixed plastic waste can be successfully converted into high-quality, reusable resources.
