    Collaborative learning methodology for reusing waste produced during university educationMetodología de aprendizaje colaborativo para la reutilización de residuos producidos durante de la formación académica universitaria
    (2022) Rodriguez-Grau G.; Valderrama-Ulloa C.; Vidal F.; Sandoval C.
    © 2022This study develops a collaborative learning methodology for reusing waste generated in academia, without compromising learning objectives, while fostering environmental awareness in students. The methodology applied is divided into five sections: 1) identification of university courses that generate waste, 2) technical feasibility assessment for reusing generated waste, 3) intervention proposal design, 4) methodology’s implementation, and 5) methodology’s evaluation. The results show that collaborative learning allows first-year students to learn from the experience and knowledge of last-year students, promoting an increased and more adequate cognitive load than that of individual learning. In addition, 80% of the waste generated in practical teaching activities was reused. It is conclude that the methodology implemented here contributed to the creation of student awareness about environmental issues (waste) that students may face throughout their professional careers.

    Examining building deconstruction: Introducing a holistic index to evaluate the ease of disassembly
    (Bloomsbury Publishing Plc., 2025) Hernandez Lopez Hector Enrique; Diaz L.; Rodriguez-Grau G.
    © 2025 Elsevier B.V.The construction industry faces significant environmental challenges, with 35 % of global construction and demolition waste ending up untreated in landfills and <9 % of materials reused worldwide. Industrialized and circular construction approaches hold promise for sustainability, especially by promoting building designs for easier disassembly and material recovery. However, assessing building deconstruction potential remains challenging, exacerbated by the interchangeable use of disassembly-related terms, leading to misunderstandings of deconstruction and its measurement. This study addresses these issues by proposing a Disassembly Ease Index (DEI) based on seventeen key variables identified through a comprehensive literature review. The DEI, tested in a case study, was found to be sensitive to factors such as connection types, required disassembly tools, and deconstruction methods, all of which significantly influence value retention options like reuse. The research not only clarifies deconstruction terminology and confirms the relationship between more industrialized, circular designs and greater disassembly efficiency but also offers a practical tool for assessing the deconstruction potential of buildings.
