- Technology description
- Waste of man-made fibres generated at an acrylic fibre plant as off-spec fibre, tow, spinning waste, and trimming/handling losses arising across polymerization, spinning and downstream washing/drying/finishing steps (cradle-to-gate plant waste stream).; Spinning/extrusion step converting acrylic polymer dope into as-spun fibre/tow. The user technical description indicates that waste includes off-spec fibre/tow and spinning waste, so a distinct spinning unit operation is modelled. Yacout et al. (2016) supports inclusion of manufacturing steps and generated waste within a cradle-to-gate acrylic fibre system boundary, but detailed operating conditions are not provided in the given excerpt.; Flow represents a plant-level mixed stream of man-made fibre scraps/offcuts (not fabric wet-processing residues), consistent with the ILCD 'Production mix, at plant' field.; Treatment is not defined in the flow; route ends at generation and on-site handling/temporary storage for off-site management.; Primary technology context anchored to acrylic fibre manufacturing as the closest matching reference cluster (C1).
