Innovation Center Prof. Dr. rer. nat. habil. Steffen Fischer & Prof. Dr. rer. nat. Frank Miletzky

Biorefinery and Cellulose

The Innovation Centre (IZ) is dedicated to the task of revolutionising the chemistry of pulping wood and other fibre raw materials such as straw, hemp, etc. as well as residual materials.
The focus of the IZ is an innovative, patent-pending pulping process that combines simple, unpressurised process technology, single-stage process control, the exclusive use of non-toxic and sulphur-free chemicals and energy-saving regeneration.
The application potential of the fibres produced is particularly evident in the field of packaging and textile technology, but the lignins also have interesting properties.
