#Wood and pulp are the main raw materials for the man-made cellulose fibers produced by the Lenzing Group. The cellulose used as the base material for pulp and fiber production accounts for 40% – 50% of the #wood substance.
Cellulose occurs in the course of photosynthesis in plants. In this biochemical process, a plant converts carbon dioxide (CO2) from air and water into organic material with the help of energy from the sun and releases oxygen (O2) into the air. Forests are therefore a supplier of energy and a neutral raw material in terms of the climate. When #wood is used, no more carbon dioxide can be released than was previously contained in the plant.
Cellulose is the world’s most important biopolymer by far. About half of the global biomass consists of this material. It provides the structure of all plant matter. From a technical point of view, cellulose is the reinforcement material of one of the highest performing versatile composite materials, namely wood.
As a soft, voluminous “packaging material”, cellulose provides soft protection for valuable seeds and also serves as fluff, for example for poplar trees and their airborne distribution. Cellulose is found as hard spikes for cacti which can be driven into wooden boards like nails. And we keep discovering previously unknown properties of this unique biopolymer.
About 180 million tons of pulp is produced every year, about 15% of the wood harvested worldwide. Most industrial pulp is used by the paper industry, whereas the fiber industry only accounts for two to three percent, a negligibly low percentage of the entire wood harvested in the world each year.
Lenzing fibers are part of a self-contained raw material cycle. Biodegradability is inherent to Lenzing fibers because of their botanic origin, an origin confirmed by certifications (DIN CERTCO, Biobased und Vinçotte).
