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

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.

Reporting of food waste in the EU – Results of current estimates in Germany

In February 2019, the German Federal Cabinet adopted the 'National Strategy for Reducing Food Waste', setting a framework for the future direction of this initiative. Among other things, it stipulated that an inter-ministerial "Indicator 12.3 Working Group" should prepare the data bases and methods for nationwide balancing of food waste generation (baseline). Based on existing 2015 data, this status quo analysis will be used as a starting point to agree on milestones for the respective sectors.

Combining laser cleaning and LIBS: fast and precise recycling of metal alloys

In respect of a limited amount of raw material, costs, CO2 and waste reduction, high precision metal recycling is getting more and more important these days. Contaminations of the melt with unwanted or outright detrimental elements (e.g. C, S, P, Cu or Pb in steel, Cr or Ni in low-alloy steels, Li in aluminium and so forth) are a huge liability toward the ‘‘alloy-to-alloy’’ recycling goal and essentially the only option in this case, is either costly dilution with clean raw materials, downgrading or worst case scenario discarding.

Development of local municipal solid waste management in the Western Transdanubia region of Hungary

Hungarian municipal solid wastes (MSW) management has developed tremendously over the past 15 years. More than 3,000 landfills and dumps had been closed, just to mention one improvement. However, still, lots of work is necessary to accomplish the EU’s ambitious aim of decreasing landfilling and increasing recycling and composting.

The new Waste Framework Directive and its impact on textile waste
© Lehrstuhl fĂźr Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2020)
In the course of implementing the circular economy package of the European Union, the Waste Framework Directive was amended recently. Textiles are no longer the poor relation of waste management but have come to the fore.
