The REMAGHIC project is a 3 years project divided into 7 WP’s, the latter two being in charge of the project Exploitation, Dissemination and Communication activities (WP6), and the project Management (WP7)
Regarding the technical implementation of the project work plan, the project will build its foundations on the research of recovery processes of those rare earths that will be later used to be alloyed with magnesium. This work will be done in WP1, where the industrial collaboration of Relight and ITRB will be key to increase the TRL level that will be developed by the project research partners such as KU Leuven, Tecnalia, Fraunhofer and Relight as well. All the processes will be fed with the same residues (coming from Relight’s processes and acquired by ITRB to complete a full overview of possibilities) and compared in order to measure the cost of recovering each element and set it against its foreseen contribution to magnesium.
The same will be done with magnesium in WP2, where the recycling routes from magnesium dross & sludge and scrap will be researched in order to obtain secondary magnesium. This work package will also evaluate the recycling of magnesium alloys that already contain rare earths, measuring the rare earth content and the feasibility of recovering the dross and scrap coming from this Mg+REE alloy as well. The obtained secondary magnesium will need to be competitive in price and performance. Regarding the overall alloy price, LCCA analyses will be carried out later in WP5 to measure the progress so that every possible deviation from the project expected results can be solved in time. Regarding the material performance, different experimental tests will be carried out to verify the secondary magnesium based alloys can replace non recycled ones, including some sector specific tests as corrosion for the aeronautics industry and in vitro biocompatibility for the biomedical sector.
Both work packages WP1, and WP2 will feed WP3, where the alloying process will be studied. It is important to note here that though many rare earths can be alloyed with magnesium to modify its behaviour and microstructure, the contribution of each rare earth, the influence of the recycling process on the rare earth contribution, the alloying process parameters, and different element combinations need to be assessed quantitatively as much as qualitatively, which will be done with the decision matrix obtained in WP1 and completed with this WP tasks.
While many of the tasks in the aforementioned work packages will be carried out on a laboratory scale, this project aims to develop a demonstration system, proving the developed technologies work and operate on a pre-commercial scale. WP4 will deal with the magnesium recycling and Mg+REE alloying technology up scaling to industrial level; it will demonstrate the process efficiency and the obtaining of the final alloys on the industrial facilities of Grupo Antolín (magnesium recovery, alloying and sample manufacturing). It will identify final operational and manufacturing issues, making sure the technology can reach the market one year after the project ends.
The evaluation of the recovery processes efficiency and thus, the project success, will be carried out by the last work package in this description: WP5 will carry out Life Cycle and Cost Benefit Assessment, updating current LCA of each process to the advance posed by the project, validating the LCA models, and providing with important indicators on each of the strategies efficiency, environmental impact and cost
