Research

This project serves to support the project partners of the Josef Ressel Center "Restex", in which various recycling strategies for blended textile fabrics, primarily polycotton (cotton-polyethylene terephthalate blended fabrics), are developed and analyzed. During their service life and especially during thermal reprocessing, the polyester chains are degraded by chemical (detergent), thermal, mechanical or hydrolytic influences. Re-granulated polyethylene terephthalate (PET) is shear-sensitive and thermally sensitive during thermoplastic reprocessing. As a result of the reduced molecular weight the melt viscosity, melt strength and mechanical properties are drastically reduced compared to virgin polyesters. Hence the reuse of the polyester in equivalent applications is limited. The services provided by the Institute of Environmental Biotechnology (Bioplastics Technology Group) include the preparation of the textiles for the subsequent separation processes of cellulose and polyester as well as the performance of extrusion trials for the production of Re-PET granulates on a laboratory and production scale. The primary aims of these tests are (i) to optimize the mechanical properties of the recovered polyesters by means of analyses and (ii) to adapt the preparation and compounding process and, if necessary, (iii) to add additives to the recovered polyesters or surface modifications of the cellulosic residues.

SONIA-ProQ makes it possible to make soy value chains in Austria more resilient and sustainable. Through the further development of special applications based on near-infrared spectroscopy (NIRS), fundamental contributions are being made to develop and improve the use of sensors and real-time process control in the processing of soybeans into animal feed. An integrated feeding trial with fattening pigs supports the quantification of the potential. In addition, a special soybean training course is being set up, which will also lead to quality improvements at the processing and feeding level. The basis for this work is the exchange of experience and knowledge between the 9 project partners and 7 organizations in the Expert Council. Together, they form a soy network that has never before come together in this form in an R&D project in Austria. SONIA-ProQ addresses the SDGs (zero hunger; quality education and sustainable consumption and production) and makes an important contribution to the Austrian protein strategy. The results of the project enable the consortium partners to position themselves more strongly in the growing soy market in the long term and also address the interests of consumers with regard to GMO-free, regionality and organic farming.
