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.

Metal recovery over the product life cycle

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 Borealis Borcycle™ M Demo Plant – Borcycle™ M as Best Practice

Borcycleâ„¢ M is the mechanical recycling platform of Borealis, setting new standards for what is possible in mechanical recycling, enabling previously unattainable applications from cosmetics packaging through to mobility.

The heat is on! - From the material characterisation of spent refractory bricks to sensor training (practical examples from Project ReSoURCE)
© Lehrstuhl für Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (12/2024)
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.

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.

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.

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.

Measuring the Flow Properties of Secondary Plastics
© Lehrstuhl für Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (12/2024)
Recycling of plastics, particularly in high-value applications, is essential for sustainable resource management and achieving climate targets. A critical challenge lies in developing robust processing methods that ensure consistent feeding of secondary raw materials into recycling machinery.
