Viscose Rayon (viscose rayon)

Viscose rayon is a regenerated cellulose textile fibre — a semi-synthetic fibre made by chemically dissolving and re-forming natural cellulose (wood pulp or other plant fibre) into a usable textile fibre. It bridges natural and synthetic fibres: the raw material is natural cellulose, but the processing is chemical. Its wastewater generation benchmark is 150 m³ per tonne of product, lower than viscose filament yarn (500) but still water-intensive.

The viscose rayon process, like its filament and staple-fibre relatives, uses caustic soda, carbon disulphide and sulphuric acid, producing effluent laden with sulphate, zinc, sulphide and organic load. It is part of the regenerated-cellulose family that the wastewater generation standards target for its high water and chemical use.

For recyclers, viscose rayon is relevant as part of the regenerated-cellulose / textile material group and the broader textile recycling theme, rather than as a recycling process. It is one of the three named viscose sub-categories (with filament yarn and staple fibre) in the wastewater benchmarks, and it connects to cellulose and textile-waste recovery as a material class.

The practical relevance is contextual. Viscose rayon illustrates the water and chemical intensity of virgin regenerated-cellulose production, reinforcing — alongside viscose filament yarn and staple fibre — the environmental argument for textile and cellulosic-fibre recycling. For a recycler in the textile or fibre space it is useful to recognise as a major fibre type with a heavy production footprint; for most recyclers it is simply one of the named water-intensive industries in the wastewater generation standards.
