<p>Integrating climate change education into engineering education is essential to prepare students for an uncertain and problematic future. The waste sector is a major consumer of natural resources and emitter of greenhouse gases, which is why it is a central theme in the training of engineering students. This paper presents the main takeaways from a pilot training module based on design fiction. The module aims to develop futures thinking in engineering students by helping them to imagine waste management in different climatic and technological contexts. An analysis of the futures images based on written output shows that the training module enables students to generate different technological schemes for waste recovery, which are conceived in their social and cultural context. Students nevertheless struggle to imagine futures that are radically different from lifestyles in a consumer society. Only output imagining a future of collapse explores ways of living that depart from our current lifestyles. Articulating the temporalities of technological and climatic processes and understanding low-tech approaches appear to be two opportunities for perfecting the module.</p>
