Flex-id retrofit: hyperspectral AI sorting of multilayer flexibles
Flex-ID Retrofit enhances material recovery facilities by integrating a hyperspectral AI sorting module to accurately identify and separate multilayer polyolefin flexibles. This solution improves recycling efficiency by overcoming conventional sorting limitations.
Overview
Flex-ID Retrofit is an innovative solution designed to improve the recycling efficiency of material recovery facilities (MRFs) and collection hubs. By integrating a hyperspectral AI sorting module, this retrofit identifies and separates multilayer polyolefin flexibles, including those with metallization, inks, and coatings, from mixed waste streams. The technology enhances sorting accuracy and enables cleaner downstream recycling and conversion processes, addressing a significant challenge in waste management.
Technical specifications
Key features:
- The system includes a compact near-infrared (NIR) and hyperspectral line-scan combined with an RGB camera.
- Utilizes a sensor-fusion model incorporating physics-informed features to effectively handle metallized and glossy layers.
- Machine learning classifiers identify material family and brand-specific cues.
- Triggers an air-knife or robotic pick to efficiently eject target films into dedicated bins.
- Developed with a robust ML pipeline for improved sorting accuracy and reliability on real-world waste, including folded and contaminated materials.
Technology readiness level
Currently at Technology Readiness Level 3, Flex-ID has undergone initial concept validation. The development plan includes four phases: defining requirements and building a spectral library, preprocessing and model iteration, integration and safety testing, and a pilot program at a partner site. These phases will further validate and refine the system in preparation for commercial deployment.
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and offers an efficient, cost-effective alternative to traditional plastic management systems, which often rely on outdated processes that fail to address the majority of global plastic waste.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.
