Critical raw materials – Advanced recycling technologies and processes: Recycling of rare earth metals out of end of life magnets by bioleaching with various bacteria as an example of an intelligent recycling strategy
Romy Auerbach,Katrin Bokelmann,Rudolf Stauber,Oliver Gutfleisch,Sylvia Schnell,Stefan Ratering +5 more
TL;DR: In this paper, the recycling potential of end-of-life magnets was investigated by means of bio-leaching with various bacteria, whereby the experiments were done in shaking batches, whereby in parallel the chemical leaching represented by abiotic controls was followed.

Towards an Alloy Recycling of Nd–Fe–B Permanent Magnets in a Circular Economy
Oliver Diehl,Mario Schönfeldt,Eva Brouwer,Almut Dirks,Karsten Rachut,Jürgen Gassmann,Konrad Güth,Alexander Buckow,Roland Gauß,Rudolf Stauber,Oliver Gutfleisch +10 more
TL;DR: In this paper, material-to-material recycling approaches are presented to maintain the magnet alloys and use them directly for a new magnet production loop, where the recycled magnets compete well with those made from primary materials, that is, in terms of magnetic properties and production costs.

Comparative Analysis About Degradation Mechanisms of Printed Circuit Boards (PCBs) in Slow and Fast Pyrolysis : The Influence of Heating Speed
Fabian Diaz,Benedikt Flerus,Benedikt Flerus,Samant Nagraj,Katrin Bokelmann,Rudolf Stauber,Bernd Friedrich +6 more
TL;DR: In this article, a detailed analysis of the degradation mechanisms during slow pyrolysis as well as its deflection under fast heating speed was made based on continuous off-gas analysis by Fourier transform infrared spectroscopy (FTIR).

New efficient Recycling Process for Li-ion Batteries
Daniel Horn,Jörg Zimmermann,Rudolf Stauber,Oliver Gutfleisch +3 more
- 01 Jan 2018
TL;DR: In this paper, a new functional and material specific recycling process was proposed to recover, recondition, and reuse Li-, Ni- and Co-containing chemical compounds and high-grade carbons for remanufacturing new cells.

Recyclable Phosphor Films: Three Water-Soluble Binder Systems Enabling the Recovery of Phosphor Powders in White LEDs
Matthias Hämmer,A. Gassmann,Armin Reller,H. von Seggern,Oliver Gutfleisch,Rudolf Stauber,J. Zimmermann +6 more
TL;DR: In this paper, a recyclable luminescence down-conversion film for commercial white light-emitting diodes (LEDs) is introduced to avoid waste of valuable materials such as rare-earth metal-containing phosphors.
