In collaboration with the Circular Economy University-Company Classroom of the Faculty of Engineering Gipuzkoa, UPV/EHU, Provincial Council of Gipuzkoa) from Thursday 7 to Saturday 9 (November) we will be in the txoko Where does the sea begin?
Under this slogan, primary microplastics and the origin of secondary microplastics derived from the degradation that plastic undergoes in marine conditions will be shown. In this line, the GMT collaborates with the LTC AquEus Transboundary Cooperation Laboratory to advance in the analysis of the effect of these pollutants. It also includes work by the GMT on the mechanical and chemical recycling of marine, urban and industrial waste.
 
For the development of sustainable production processes, aspects such as the waste hierarchy and the efficient use of resources promoted by the circular economy must be considered. For this reason, the GMT has been working for more than 2 decades on the valorisation of compounds derived from waste of renewable origin. These include compounds derived from wood processing, such as tannin and lignin, both of which have a wide range of applications from incorporation in the synthesis of phenolic resins to the formulation of cosmetics. We have also been passionate about the physical, chemical and mechanical properties of latxa sheep wool for many years. Therefore on the stand you will find some examples, such as wool composites processed as biodegradable 3D printing filament and sections of surfboards with wool reinforcement.
We would like to thank Tytti Thursberg, Mater Museoa, Yurre Peñagarikano (URKOME), LTC AquEUS (Euskampus Fundazioa) and all the people of the GMT who have participated in the research.

On July 3, 2024 the agreement Circular Economy in Engineering was signed with the Department of Sustainability of the Provincial Council of Gipuzkoa. This agreement includes two lines of work in which GMT will participate. Firstly, we will continue with the study of textile waste, analyzing physicochemical processes of textile waste recycling. In addition, we will evaluate the possibility of incorporating different renewable and recycled materials in the manufacture of the motorcycle that is being developed at the Engineering Faculty Gipuzkoa within the framework of the MotoStudent project.

In Cartagena de Indias, Colombia, on May 19-23, 2024, the "39^th International Conference of the Polymer Processing Society (39 PPS)" took place, organized by the Polymer Processing Society, Universidad de los Andes, and the Instituto de Capacitación e Investigación del Plástico y del Caucho (ICIPC). Our pre-doctoral researcher, Ana Cristina Restrepo Montoya, participated as a speaker, presenting her research work titled "Targeting Recyclability in Crosslinked Biobased Polyurethanes through Thermoreversible Bonds"

Cristina Peña, researcher-teacher of our group presented the research Analysis of the degradation of plastic marine litter at the EMCEI congress (6th Euro-Mediterranean conference for environmental integration) held in Marrakesh (Morocco) from May 15 to 18 and organized by Springer and the Université Cadi Ayyad and the University of Stax.

Aitor Arbelaiz, Cristina Peña and Ander Larruskain, researchers our group, collaborate with Elhuyar in the project called "Gluoien mahaia". This project, promoted by Elhuyar, has the collaboration of the Department of Economic Promotion and Strategic Projects of the Provincial Council of Gipuzkoa. Under the name "Research for sustainability to inspire young people", the aim is to bring young people closer to the world of research. To this end, with the help of research groups, the young people themselves carry out real research.

The research team of the GMT group has been researching renewable materials for more than 20 years, and one of them is latxa sheep's wool. This type of wool is hardly used nowadays in any sector, and around 2,000 tonnes are generated each year. They have explained this concern to a group of secondary school students from the IES Txindoki in Beasain and have jointly developed composites with latxa sheep's wool as reinforcement that could be used in construction. In a first session they presented the project at the school itself: they explained to the students the aim of the project and the first experimental part. Subsequently, the students were in our laboratories to  develop the mechanical characterization of the specimens obtained and evaluate the results. In a final session, the students will discuss the results with the researchers.
