11th International Conference
on Fiber & Polymer Biotechnology

The 11th International Conference on Fiber and Polymer Biotechnology (IFPB 2022) will be held from 13th to 15th November 2022 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.

IFPB Opening

Georg Guebitz (BOKU)

Biobased polymers and fibres:

To tackle the world's plastic problem, bio-based polymers are the future. Many microbes are capable of producing biopolymers. How can we use such microorganisms as cell factories for production? Are polyhydroxyalkanoates (naturally occurring, biodegradable polyesters) the future of biopolymers? And where can we find aminopolysaccharides and aminopolysaccharide-glucan complexes?

Biorecycling & Sustainable Processes

Once the plastics are no longer used, it is difficult to recycle them. Some recycling strategies will be presented in this session: depolymerization of PET by a thermotolerant enzyme scaffold or the use of the metagenomic polyester hydrolase PHL7, engineered metabolism in Pseudomonas taiwanensis, and enzymes for energy conservation in refining or recycling cellulose fibers. But how are these recycling strategies compatible with industry requirements for hyper-stable protein design? And how can we effectively use resources for functional and smart textiles?

Coffee Break

Enzymatic decomposition of plastics

Worldwide, the plastic production and its use are accelerating and they are becoming one of the most discussed issues in the media and in different research sectors. In 2017, more than 27.1 million tonnes of plastic waste were produced in the EU with only 31.1 % being recycled, the residual 41.6 % were incinerated and 27.3 % landfilled. Conventional recycling still have some caveats regarding the complete separation of all the components, e.g. for multilayer and plastic mixes, thus not allowing to retrieve highly pure materials. Microbial and/or highly specific enzymatic processes are promising strategies in order to step-wise recover monomers from blended and multi-layer materials and/or for their bio-degradation.

The plastics biorefinery

Decomposition of plastics will lead to valuable building blocks which can e.g. be used for re-synthesis of polymers or as substrates for bioproduction. In the latter case, recent advances involve the engineering of microorganisms to use pure or mixed monomers as substrates to produce biopolymers or platform molecules. Such plastics biorefineries will ultimately help to close the plastics-cycle.
