Mineral Wool Waste – From on-site Analysis to Recycling
© Lehrstuhl für 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.

Limits and Challenges of the Calculation and Verification of the Recycling Efficiency of Lithium-ion Batteries posed by the new European Battery Regulation
© Lehrstuhl für Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (12/2024)
The new European Battery Regulation, introduced as part of the EU's Green Deal, presents significant challenges and changes in recycling lithium-ion batteries (LIB). This regulation not only raises the general recycling efficiency quotas from 50 % to 65 % by 2027 and 70% by 2030 but also sets specific recycling efficiency requirements for cobalt (Co), copper (Cu), lithium (Li), and nickel (Ni) at the elemental level.

Viable recycling approaches to electrolyser stacks

To ensure the sustainable use of the world's limited resources, it is essential to integrate principles of circularity into every new technology or product development. The ReCycle project deals with the reduction of environmental impact and related recycling capabilities (of hydrogen technologies) and aims to apply these circularity principles to technologies within the hydrogen value chain.

Implementation and evaluation of a real-time capable approach to sensor-based sorting using CNNs
© Lehrstuhl für Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (12/2024)
In state-of-the-art optical sorting, engineered image processing algorithms are commonly used to identify materials. However, for complex material textures and high- ensity material streams, these approaches are often unable to maintain the desired sorting quality. Convolutional neural networks (CNNs) have been proven to outperform such approaches in their ability to classify objects in images.

Comparative Analysis of Transfer and Continual Learning for Vision-Based Particle Classification in Plastics Sorting for Recycling
© Lehrstuhl für 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.
