Lenzing group

Problem statement

Reducing dependence on fossil fuel by developing biobased fibers for packaging application

Executive summary

Lenzing produces wood-based viscose fibers, modal fibers, lyocell fibers and filament yarn, which are used in the textile industry — in clothing, home textiles and technical textiles — as well as in the nonwovens industry. 0 % Pulp, 10% biobased materials (acetic acid, furfural, xylose, soda), 50% Bioenergy a) Tensel (Tensel Lyocell, Tensel Modal, Tensel Lyocell Filament, b) EcoVero c) Veocel (Veocel Lyocell, Veocel Specialty Viscose) d) Lenzing (Lenzing Lyocell, Lenzing Modal, Lenzing Viscose)

Value chain description

The biorefinery concept ensures that 100 percent of wood components are used to produce pulp for their botanical fibers, biorefinery products, and bioenergy. Beech wood is hydrolysed to get the cellulose fraction. Hemicellulose and lignin fraction which gets isolated from pulp during bleaching and krafting is used for synthesis of biobased chemicals (furfural, xylose, acetic acid).

Market deployment considerations

Cellulose fiber market size is projected to grow from USD 24.11 billion to USD 44.5 billion by 2030 at a CAGR of 9.2% during forecast period

Environmental considerations

: Lenzing reports the corresponding implementation measures and the progress it has made in its annual sustainability report. The rating provider also highlighted Lenzing’s comprehensive measures to reduce air pollution, wastewater and greenhouse gases.

Social Considerations

This project aims to support the development of certain rural areas by using natural resources in a sustainable manner as well as fostering alternative income opportunities for the communities. Part of the project is the afforestation of 20 ha of degraded land. This area surrounds the so called Eco-Social Farm, an institution for people with disabilities. As part of the project, a collaboration with Eco-Social Farm has been set up to employ people who would not have the opportunity to get a job in the normal labor market
