Carbon Footprint Reduction in Polyester Production
topic
Decarbonisation pathways for polyester: (1) Renewable energy in spinning and texturing (most energy-intensive steps, 60–80% of production GHG from electricity); (2) Green hydrogen for polymer synthesis (replacing natural gas); (3) Bio-based PTA from bio-p-xylene (Anellotech, Virent); (4) Carbon capture utilisation (CCU): CO₂ to methanol to EG pathway; (5) Process intensification: reducing melt time, increasing throughput per energy unit. SBTi (Science Based Targets initiative): leading brands commit to Scope 3 (supply chain) emission reductions aligned with 1.5°C pathway.
Role
Carbon footprint reduction of polyester production connects material science with energy systems, process engineering, and climate policy. It is increasingly important as brands face regulatory and investor pressure for supply chain decarbonisation.
