CIDAUT firmly committed to Circular Economy.

On March 27, 2018 took place the fourth meeting on Circular Economy promoted by the Regional Government of Castilla y León through the Ministry of Development and Environment and the Ministry of Economy and Finance.

This time the title of the meeting was “Circular Economy and Bioeconomy: Zero waste – Waste to resource” and it focuses on the use of waste as subproducts instead of dispose them in landfills as a way to accomplish with the principles of the Circular Economy.

During the day, legal possibilities in order to obtain an end-of-waste consideration were highlighted. The European Commission has already set down end-of-waste criteria for glass, metal and copper scrap and criteria for various other materials that are under development. This latter aspect, end-of-waste concept, is regarded as a first step toward these materials to be considered as raw materials for other processes more than as a waste that have to be managed.

Certification processes around Circular Economy were also reviewed which are an important tool for enterprises to demonstrate its actual commitment with Circular Economy.

Finally, there was a time for exchanging information about existing positive experiences on waste re-used within Castilla y León, mainly related with the agri-food sector.

CIDAUT participates in Circular Economy Events in Valladolid

Different events on Circular Economy have taken place in the last months in Valladolid and CIDAUT took the opportunity to participate in them.

Entrepreneurs from all over the country gathered on Friday 3rd and Saturday 4th of November in Valladolid to promote an innovative model of a more responsible economy. The Agency of Innovation and Economic Development of Valladolid celebrated this weekend the first edition of Circularweekend, a national innovation meeting to learn to launch ideas with circular business models, modernize companies implementing more efficient processes in the use of resources and get in touch with all the agents of the circular economy ecosystem.

The meeting, organized by Enviroo and aimed at making the concept of circular economy more practical, has had workshops to solve the challenges of this type of economic model and launch new projects.

CIDAUT was present in the first day and with its participation helped to promote in this way an innovative model of economy based on the value of products, materials and resources being kept in the economy for as long as possible, thus helping to minimize the generation of waste.

Moreover, CIDAUT has participated in the conference on “Circular Economy: New models of production and consumption” organized by the Institute for Business Competitiveness of Castilla y León (ICE) on 29th of November. It took place at PRAE (Environmental and Educational Proposals) facilities in Valladolid. This initiative is part of the Circular Economy and Bioeconomy Strategy, promoted by the Government of Castilla y León through the Departments of Development and Environment and Economy and Finance, respectively. More specifically, it belongs to  the activity of dissemination of the Circular Economy and the bioeconomy between the society of Castile and Leon in order to promote initiatives in cooperation.

The attendance and participation in these conferences by CIDAUT has allowed knowing in greater depth the framework of work on the use of waste within the scope of the circular economy, as well as the main barriers and opportunities that they generate.

Remaghic, two years running!

Last September in San Sebastian, the Remaghic Project partners held the 24 month meeting general assembly. During the last months many decisions have been taken on the best chain of processes to recycle rare earths and on the design of the currently manufactured facility to recycle Mg and produce the Remaghic magnesium alloy. Currently, casting tests with different alloying elements have been done, corrosion and mechanical testing campaigns are ongoing, and the project faces the last project year where the industrial validation and the LCA will highlight the results achieved.


The meeting took place on the 20th and 21st of September. During the first day, the meeting was focused on the last activities done to recycle rare earths from different residue streams (WP1), on the update of the alloy development (WP3), and on the industrial facility that has been designed and manufactured to enable magnesium foundries recycle in house their own scraps and drosses (WP4). Currently, the Remaghic Cosnortium is looking for partners to test this facility, if you are interested, contact us at The last part of the first day was dedicated to the LCA analysis of the different ongoing processes in the project.

The second project day was fully dedicated to the Dissemination, Communication and Exploitation work package. Now that results are on the table, Remaghic partners are making an effort to contribute with their knowledge on recycling processes to Europe’s scientific and manufacturing community. To mention one example, Cidaut presented the results and next steps for the Remaghic project at the International Magnesium Association European Committee Meeting last 25th of October held at Brunel University (BCAST) London. In November Remaghic project parntes will be also taking part at the23rd SETAC Europe LCA Case Studies Symposium with two posters respectively dedicated to rare earth elements recycling and magnesium recycling methodologies. The Symposium, organized by the International Life Cycle Academy will take place in Barcelona, meet us there!


Second Consortium Meeting of NEOHIRE

The second Consortium Meeting of NEOHIRE project (NEOdymium-Iron-Boron base materials, fabrication techniques and recycling solutions to HIghly REduce the consumption of Rare Earths in Permanent Magnets for Wind Energy Application) took place in San Sebastián (Spain) on 18th-19th October 2017. Representatives of all the different companies and research centers that make up the NEOHIRE consortium attended the two-day meeting.


During the first day, the meeting was focused on the technical activities done during the first six months of the project. Participants of WP1 (“Development of new NdFeB materials solutions for permanent magnets”) and WP2 (“Permanents magnets manufacturing and characterization at lab scale”) showed their first results. The last part of the first day was dedicated to the WP 5 (“Life-Cycle Assessment and Cost-Benefit Analysis of the developed solution”) concerning the different ongoing processes in the project.

The second project day was fully dedicated to the Management and Dissemination of NEOHIRE. The main aspects of the project were reviewed: deliverables, future meetings, etc.

This project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 720838

Remaghic Mid Term Review and upcoming events


Partners of the Remaghic project met at the European Commission the past 2nd of February to present the project status after eighteen months of research. The project so far has developed a magnesium recycling methodology for magnesium scrap and scum with the collaboration of CIDAUT with Grupo Antolín, in which recycling efficiencies of 80% have been achieved. This work done at laboratory level will be upscaled in the second half of the project to reach a TRL of 7.

A lot of effort in the Remaghic project has been devoted to the recycling rare earths. Different processes are featured in the project, from solvent extraction, hydrometallurgical treatments, thermal and pyrometallurgical treatments and molten salt extraction. These processes have been combined and intertwined to optimize efficiencies and yields and the work done on each selected residue stream will be soon presented at the European Rare Earth Resources (ERES) conference next May in Santorini, Greece by partners of the Remaghic Consortium Tecnalia, KU Leuven and Relight.

The involvement of the project end users has proven to be very important in the alloy requirement definition in order to help focus the rare earth recycling processes to the specific elements that have been selected to improve the recycled magnesium mechanical performance.


Finally, Life Cycle Analysis has endeavored to look at each of the processes and their environmental indicators. Merging different processes, at different technology readiness status, and balancing technical, economical and environmental indicators is a complex task coming ahead for this project in which the life cycle analysis and life cycle costing analysis will play an important role to guide the decisions that the project will need to take.
