The Josef Ressel Center (JRC) for Recovery Strategies for Textiles (ReSTex) addresses one of the pillars of the European Green Deal in achieving sustainable societies and bio economies: textile recycling. Focused on cellulosic textiles and the separation of cellulosic blends of cotton/polyester, the JRC ReSTex is hosted by the University of Applied Sciences Wiener Neustadt, at the Biotech Campus Tulln, and funded by the Christian Doppler Research Association (CDG).

The voestalpine Group's High Performance Metals Division is globally known for producing high-quality steels using well defined combinations of alloy elements and sophisticated production techniques. What makes these steels special is the set of exceptional properties such as resistance to corrosion and heat, high purity, and extreme durability that makes our products suitable for diverse applications, from aviation to construction of turbine blades and high pressure die casting tools.

The heat is on! - From the material characterisation of spent refractory bricks to sensor training (practical examples from Project ReSoURCE)

Refractory products are essential for high-temperature industrial processes, from steel and cement production to waste incineration and many more. Harsh environmental conditions in these applications result in the frequent renewal of refractory lining.

Recycling paper and board from mixed waste streams: Determining data
requirements for a reliable environmental assessment
© Lehrstuhl für Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (12/2024)
To increase the recycling rate of paper and board, we investigate how yet unexploited paper and board from lightweight packaging waste can be recycled. Therefore, an environmental assessment via life cycle assessment (LCA) is crucial for the project to determine if the benefits from recycling exceed the efforts needed.

Geophysical characterization of an industrial landfill to quantify raw materials and detect possible leakages
© Lehrstuhl für Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (12/2024)
Our work aims at the geophysical characterization of a landfill associated to an industrial chemical plant. The landfill is fully enclosed by a non-permeable liner around all boundaries (consisting of PVC and clay layers). The last waste deposals took place in the 1970’s, yet recent events suggest possible leakage of contaminants. Hence, it is necessary to identify failures of the liner and leaking of leachates.

De-oiling of grinding sludge: What is the potential of mechanical de-oiling
by a centrifuge?
© Lehrstuhl für Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (12/2024)
Grinding sludge is a waste flow emerging from semi-finished products brought to their near-net-shape dimensions by grinding. In the grinding process, up to 50 wt% of the workpiece can be grinded off (Hagedorn et al. 2022). A lubricant is constantly sprayed onto the contact point between grinding tool and workpiece to reduce heat development, to remove the emerging metal chips and to reduce friction (Klocke 2018).

Advancing Polypropylene Recycling: A Study on Possibilities to Improve Sorting Systems

The current use of recycled polypropylene (PP) is still limited as the quality cannot compete with virgin PP. In addition to other influences, the mixing of different types and grades of PP during recycling has a negative effect on the quality of the recycled PP.
