The 11th International Conference on Fiber and Polymer Biotechnology (IFPB 2022) will be held in Graz, Austria, within ESIB. Starting more the 20 years ago in 2000 with the first congress of this series, – biotechnology related to fibre and polymer processing is an area with strongly growing scientific and industrial interest. Biotechnology and Enzyme-technology play an important role ranging over all steps of the value chain from biopolymer production and synthesis, functionalization & processing to novel approaches for recycling. Thereby, modern technologies of biotechnology (e.g. enzyme/metabolic engineering) play an essential role towards a transition of fibre and textile industries within a circular bioeconomy.
