Sustainable chemicals sourcing

The most important chemicals used – amounting to approximately 85 percent of the overall purchase volume – are caustic soda (NaOH), carbon disulfide (CS₂), sulfuric acid (H₂SO₄), sulfur (S), sulfur dioxide (SO₂), softening agents, flame retardants, modifiers, N-methylmorpholine N-oxide (NMMO), titanium dioxide (TiO₂), and zinc sulfate (ZnSO₄). Figures for chemical sourcing are not provided for confidentiality reasons.

Supplier assessments using the sustainability criteria provided in the EcoVadis tool are outlined in the Sustainability Report 2017, page 63. The target of assessing 80 percent of the most important suppliers (by purchasing value) was reached in 2019. New targets are in development. Nevertheless, additional suppliers continue to be assessed (table “Number of suppliers responding to EcoVadis questionnaire since the introduction of the assessment in 2017”). Global Purchasing has developed its pool of suppliers on the basis of sustainability. The overall EcoVadis Score achieved by the Lenzing Group’s suppliers (52.8) is much better than the average EcoVadis Score (43.8).

80 percent of all purchased chemicals are sourced from fewer than 60 suppliers. Relationships with these suppliers are highly stable. Around 90 percent of the chemicals are sourced regionally for the Lenzing Group as a whole (table “Regionality of purchased chemicals”).
