The evolution of construction techniques has spanned millennia, integrating locally sourced materials with innovative technological advancements. The use of earth in construction demonstrates remarkable versatility, exhibiting plasticity when wet and robust solidity upon drying. The environmental sustainability and abundant availability of earth further reinforce its role in architectural practices. This research explores the integration of recycled thermoplastic technology with traditional earthen construction methods, focusing on non-structural walls combining thermoplastic frameworks and mixed earth techniques. The study places particular emphasis on recycled High-Density Polyethylene (r-HDPE), a material that has garnered acclaim for its role in sustainable development through the reuse of secondary raw materials and its high moldability. The primary function of r-HDPE in this context is as a supplemental framework supporting earthen materials. Utilizing recycling and production methods from Precious Plastic, the research emphasizes the prototyping of r-HDPE structures with diverse configurations, digitally designed to create components ranging from beams to intricate truss networks. The earthen mortar comprises fine and coarse sand, wheat straw, and lime, adhering to traditional mixed earth construction practices. While the materials share structural limitations with conventional mixed earth methods, the potential addition of composites to thermoplastics could improve strength but hinder mechanical recyclability, favoring chemical recycling as an alternative. This study prioritizes recyclability with minimal environmental impact, limiting its scope to mechanical recycling without composite additives. The objective of this study is to achieve a balance between innovative applications of recycled thermoplastics and long-term environmental stewardship, thereby enhancing the synergy between sustainability and construction practices.
Approaches to Collective Cognition in the Historic Centre of Madrid

Beyond their direct use, buildings and heritage places are objects and settings which help to guide community actions. Cognitive perception systems interact directly with the built environment through action and generate experiences that will be used for subsequent actions. This requires a reorientation towards phenomenological perspectives that query the conceptual boundary between cognition and action. Five universities from three countries (Portugal, Italy, and Spain) came together in July 2023 through an Erasmus+ BIP (Blended Intense Programme) experience, developed for the La Latina neighbourhood, in the historical centre of Madrid. The intention was to highlight the importance of different disciplines, and interdisciplinary working, for planning an urban future which includes the goals of socio-economic and environmental sustainability, happiness, and the right of residents to maintain longstanding emotional connections with their neighbourhoods. The novelty of this experience compared to existing Master’s and PhD programmes in Europe was the early and intense contact of students with the subject through the development of fieldwork over two weeks. This was led by teachers from different disciplines to provide interdisciplinary perspectives for a training programme which included architecture, urbanism, urban anthropology, geography, history, and archaeology. Through this training, the intended outcomes were twofold: to equip students with the necessary knowledge and criteria to critically address these issues and to raise awareness among local stakeholders about the negative transformations affecting historic centres and their impact on residents’ quality of life.
