Tex2Mat: Recycling of industrial PA textiles to fibres and injection moulded parts
© Lehrstuhl fĂĽr Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2020)
The project Tex2Mat is a cooperation of several manufacturing companies and uni-versities. In the course of the project two waste streams from textile companies were analysed, one was textiles made from a mixture of PET (polyethylene terephthalate) and cotton and the second one was a mixture of polyamides (PA). In this subproject regarding the PA the following members were selected in a way that all processing steps were represented along the complete value chain. The main objective the project was to analyse the whole value chain from the loom to collecting the waste, the recycling process and the production of the original product or other technical demanding products.

Residual municipal waste composition analysis – New methods for Czech waste management
© Lehrstuhl fĂĽr Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2020)
Relevant information about MW composition and proper forecasting of MW composition is crucial for relevant technical and economical modelling and business planning in the field of waste management. These include techno-economical models of MW treatment units, e.g. sorting line, transfer station, energy recovery, waste collection and transport or a regional waste collection and treatment system modelling (Kropáč et al. 2018) and complex business models concerning specific investments in waste management. In this context, there is a project under the Ministry of Environment of the Czech Republic.

Packaging recycling in EU member states – requirements from the circular economy package
© Lehrstuhl fĂĽr Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2020)
The EU has established concrete recycling targets for packaging waste for 2025 and 2030. Furthermore, the methodology for calculating the corresponding recycling rates has been amended. The new and stricter calculation methodology will potentially lead to decreases of the current rates. This will be particularly the case for plastic packaging, where denkstatt calculated a gap far above 10 % compared to smaller decreases (> 2 %) to be expected for glass or steel packaging.

Collective research projects: Reviewing gaps in the recycling of multilayer flexible food packaging

Recyclability and sustainability are conflicts in multilayer flexible food packaging, where material combinations (polymers, paper, aluminium) intend functionality. To increase the sustainability of multilayer flexible packaging through recyclable solutions, systemic and technical obstacles need to be considered. A holistic redesign approach, addressing food protection and the packaging’s end of life (collection, sorting, recycling) is essential to improve these already sustainable packaging solutions. To this, current collective research projects at the University of Applied Sciences, aim to closely link science and industry, promote research in the field of sustainable packaging and provide solutions to recycling goals of the European Union.

PlasticFreeDanube: Composition of macro-plastic waste in and along the Danube River

The reliable estimates are essential to developing measures to reduce plastic pollution and to make successes measurable and visible. For this reason, the cross-border project "PlasticFreeDanube" (PFD), which is co-financed by the European Regional Development Fund within the framework of Interreg Slovakia-Austria, aims to gain new knowledge on this topic for the Danube.

Environmental-economic impact assessment of business models in the Austrian waste economy

The dynamic macroeconomic one-region and multi-sector model WIFO.DYNK (dynamic new-Keynesian) was adapted to model the employment and value-added impacts of the Austrian waste economy in this respect. It is based on the most recent input-output tables of Statistics Austria.

Influence of pre-screening before ballistic separation on NIR-sorting quality of plastic rich 3D-fractions out of MCW

The exploitation of plastics gains more importance over time. In this con-text, material recycling is especially focused on packaging plastics. A further waste stream that contains a significant amount of plastics is mixed commercial solid waste. To assess the potential of plastics for recycling and energy recovery from these waste stream large-scale experiments were conducted. The potential of mechanical pre-processing with the aim of generating a 3D-plastics pre-concentrate was assessed. The focus of these investigations was put on the relevance of the screening stage and its influence on down-stream material processing via ballistic separation and sensor-based sorting. Results demonstrate not only that the screening of the waste leads to enrichment of plastics in coarse particle size ranges (especially > 80 mm) and transfer of contaminants, organics and minerals to fine fractions (especially < 10 mm), but also that sensor-based sorting performance can be significantly enhanced due to cleaning effects on plastics, induced by the material circulation and friction in a drum screen.

State-of-the-art and future perspectives in textile recycling
© Lehrstuhl fĂĽr Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2020)
Today, the blending of materials within textiles is an asset in the design of protective clothing and various technical applications, but material mixes and blends also found their way into retail trade. The rise in end-of-life items is thus putting pressure on waste management to develop suitable recycling processes. Still, in the textile sector, waste prevention claimed by policy seems to be a pious wish.

Tex2Mat: The recycling of towels and laundry made from PET and cotton

The project “Tex2Mat” was a cooperation between companies working in the field of recycling or textiles and universities specializing in the field of polymer engineering and recycling. There were two polymers (PET and PA) examined and the whole project divided into two subprojects.

Digital and service transformation of business models - the case of ATM Recyclingsystems
© Lehrstuhl fĂĽr Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2020)
The trend of increasing digitalization and servitization affects all industrial companies in all sectors including the waste and recycling industry, as we will present in our case study. In this case, the company ATM Recyclingsystems implemented an IoT platform from t-matix with the goal, to provide customers with products that deliver the best efficiency and optimal cycle times.
