ReTech

Material Intelligence for Smarter Recycling

Efficient recycling depends on knowing what materials are made of—not only what they look like.

RETECH brings together companies and organizations focused on waste management, resource recovery, recycling equipment, material processing, and circular-economy technologies. The 2026 event will take place from September 2–4 at KINTEX in Goyang, South Korea.

At RETECH, Headwall will present hyperspectral imaging solutions designed to identify and differentiate materials based on their spectral characteristics. This material-level information can help recycling operations distinguish visually similar substances, detect contamination, and make more accurate sorting decisions.

Visitors can explore how hyperspectral imaging supports the identification and classification of plastics, polymers, mixed materials, and other recyclable materials. The technology can be integrated into automated sorting and inspection workflows to improve recovered-material quality and increase the value captured from each material stream.

Meet Youngsoo Lee at the booth to discuss your recycling application, explore potential integration approaches, and assess whether hyperspectral imaging can provide the material information your process requires.

Better Material Decisions. Higher-Value Recovery.
