Viscose Environmental Impact and Sustainability
topic
Environmental concerns include: CS₂ emissions (toxic, 20-50 kg per tonne fibre in conventional plants), ZnSO₄ discharge in wastewater, high water consumption (150-200 L/kg fibre), sulfur recovery challenges, and deforestation risks from unsustainable wood sourcing. Modern closed-loop systems (Lenzing, Birla) achieve >99% solvent recovery, FSC/PEFC certification, and 50% emission reduction.
Role
Sustainability improvements through closed-loop technology, responsible sourcing, and circular economy approaches are critical for viscose's future viability amidst regulatory pressure and consumer awareness.
