Leadership, support and organisation for academics’ participation in engineering education change for sustainable development

In light of mounting environmental concerns surrounding the overuse and accumulation of plastic waste, the United Nations (UN) has turned its attention towards sustainable materials and the Circular Economy (CE). Polymer recycling technologies have the potential to reduce the environmental impact and carbon footprint of plastic waste production, thereby contributing to the achievement of several Sustainable Development Goals (SDGs). In response to this challenge, students enrolled in the fourth year of secondary education, specializing in technology, during the 2021–2022 academic year, developed an open-source prototype that automatically transforms polyethylene terephthalate (PET) bottles into recycled rPET filament for 3D printing using an automated pultrusion model. In this working group, one of the students identified as gifted developed the pultrusion prototype using challenge-based learning and the project method (PM), which is now known as project-based learning. The resulting prototype has the capacity to transform PET bottles into rPET filament with mechanical properties comparable to those of commercial filaments, thereby enabling the manufacture of a wide range of products through 3D printing. It is not the intention of this work to create a commercial product. Rather, it is designed to promote social and sustainable entrepreneurship, CE, and the values of Education for Sustainable Development (ESD) through the recycling of polymers by means of 3D printing production. In addition, it seeks to develop the key competences for sustainability described in the methodological framework established by UNESCO in 2017.
