  • Triboelectric separation charging tube sorting plastic flakes by contact charge polarity in an industrial free-fall separator
    22 August 2026

    Triboelectric Separation: Using Charge Difference to Sort Plastics and Minerals Instead of Fighting It

    Triboelectric separation turns contact electrification from a handling hazard into a deliberate sorting mechanism. This article covers how material pairs are selected by charge polarity, what feed moisture and particle size do to separation efficiency, and where the technique sits relative to density and optical sorting.
