RedOxRex in ERA-MIN 2 Project

Type of project: ERA-MIN 2
Name of project: Reduction/ Oxidation Recycling
Acronym of project: RedOxRec
Partners: Robert Bosch GmbH (Coordinator), HI-ERN – Forschungszentrum Jülich GmbH, National Institute of Chemistry, University of Antwerp Duration: 1. 1. 2020-31. 12. 2024

Our vision is to enable a more distributed recycling chain, where Small-Medium Enterprises (SME), individual production plants and municipalities become the main stakeholders of the recycling process chain. This shift in the recycling paradigm hinges on the dissemination of green recycling solutions throughout the territory.

The core innovation is the development of a medium-scale, environmentally friendly and low-cost hydrometallurgical process for the extraction of noble metals from End-of-Life products (e.g., electronics waste). Based on this technological breakthrough, we expect to trigger multiple ramifications from the technical, economic, social and environmental point of view. The cornerstone of this new hydrometallurgical recycling process is a completely new concept for noble metals chemical extraction by exploiting the so-called transient dissolution. This mechanism is a well-known degradation mechanism for all electrochemical applications and, opposite to conventional hydrometallurgy, does not require extremely aggressive conditions, but only a repeating change in surface (electro-) chemical potential.

We intend to transfer this, so far, the purely electrochemistry-related process to a chemical reactor (TRL 5) and to validate experimentally the process for real scrap, e.g., manufacturing refuse from electronics production. In order to assess the impact on the overall value chain, the project will deal with the evaluation of the recycling process in a decentralized network and the identification of the corresponding technological solutions for disassembly, pre-treatment and logistics. In conclusion, the data obtained the TRL5 reactor will serve as input data to verify the economical feasibility of our innovative chemistry and to assess the environmental benefit
