Increasing Resource Efficiency in the Recycling of Lithium-ion Batteries Through Advanced Mechanical Processing
© Lehrstuhl fĂĽr Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (12/2024)
In the future, large quantities of end-of-life lithium-ion batteries (LIBs) will be sent for recycling. Currently, recycling processes focus on high recovery of the black mass and its valuable components such as nickel and cobalt. However, this results in high losses of other materials contained in the batteries, such as aluminum.

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).

Mineral Wool Waste – From on-site Analysis to Recycling
© Lehrstuhl fĂĽr Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (12/2024)
Mineral wool waste has become increasingly challenging to manage within the Austrian waste management system. At present, the only available option for mineral wool waste of unknown origin is landfilling, as there are no existing recycling options.

I-STEP – A Case Study: Machine Learning Powered Condition Monitoring of a Linear Motion Industrial Vibrating Screen
© Lehrstuhl fĂĽr Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (12/2024)
Vibrating Screens, crucial in mineral and waste processing industries, usually lack adequate condition monitoring to assess condition states or predict machine errors. Addressing this issue, IFE Aufbereitungstechnik GmbH and its partners are developing "i-STEP," a digitalization solution potentially integrating any market-available sensor for a customizable, plant- wide monitoring platform. Thus far, a vibration sensor, "SES" has been developed to specifically measure oscillation patterns of vibrating screens, which is the main focus of this research.

Comparative Analysis of Transfer and Continual Learning for Vision-Based Particle Classification in Plastics Sorting for Recycling
© Lehrstuhl fĂĽr Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (12/2024)
In this study, we evaluate the effectiveness of transfer and continual learning techniques for vision-based trash particle detection and classification in plastics recycling. This task poses unique challenges for vision-based methods due to the great variety of particles in recycling material flows, their variability over time, and the lack of real recycling industrial datasets available for research.

The Allegory of Stupidity and Waste

This paper on the allegory of stupidity and waste is a more or less daring view on tomorrow’s capabilities in global waste management. A society facing seemingly unresolvable ecological challenges seems to be immune to its own overconsumption.

In the context of polymer recycling, differentiation and analysis of various polymer types are crucial for effective material separation and reuse. This study explores the effectiveness of computed tomography (CT) in distinguishing between different types of polymers based on their density and elemental composition, facilitating more efficient recycling processes.

The Use of Textile Waste for Fibre-Reinforced Geopolymer Composite
Production
© Lehrstuhl fĂĽr Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2022)
The textile industry is among the top largest industries in the world, as the demand for new products proportionally increases with population growth. In 2014, 90.8 million tons of textile fibres have been produced which is expected to exceed 100 million tons by 2025. Many different types of fibres can be used for textile production, such as cotton, hemp, nylon, polyester, however, the application of synthetic fibres had become more common compared to natural fibres in the recent years (Pensupa et al. 2017).
