Some of the challenges in implementing Education for Sustainable Development: perspectives from Brazilian engineering students

© 2019, © 2019 Informa UK Limited, trading as Taylor & Francis Group. This article aims to analyse some of the main challenges evidenced in the insertion of sustainability in engineering courses, according to the view from a sample of Brazilian students. Through a systematic literature review, a set of 10 challenges were structured to base the research instrument (questionnaire). These challenges were evaluated by 91 engineering students who participate in sustainable action programs promoted by Enactus Brazil. The collected data were analysed in terms of the averages assigned and via the multi-criteria decision technique TOPSIS, which allowed ranking the challenges. The averages were higher than 5.0 on the scale used, indicating that the students notice the existence of the challenges in the courses in which they are enrolled. The ranking via TOPSIS presented the most evident challenges: ‘Sustainable issues debated only in specific disciplines in a limited extent’; ‘Difficulty to integrate disciplines for the broad teaching of sustainability’; ‘Lack of practical and real examples of how sustainability can be embedded in the specific context of the course’; and ‘Activities and examples presented focus exclusively on environmental issues’. The results presented here may be useful for course coordinators to improve their curriculum; educators to enrich their disciplines from the findings reported here; and researchers interested in the subject can use these findings as a starting point for proposing new teaching techniques. No similar publications were found in the literature, which indicates its originality and contribution to the knowledge base

Sustainability in manufacturing processes: practices performed in metal forming, casting, heat treatment, welding and electrostatic painting

© 2019, © 2019 Informa UK Limited, trading as Taylor & Francis Group. This article aims to list the main sustainable practices developed in the processes of metal forming, casting, heat treatment, welding and electrostatic painting. When analysed the literature about sustainable manufacturing, a predominance of studies about machining is observed and the processes mentioned are few explored in academic studies. The research strategy used to reach the objective was systematic literature review, conducted for each process cited. Many sustainable practices were identified with prominence of better materials use and energy efficiency. The authors of this article believe that the information presented here can be useful for researches in their future studies and for industry professionals interested in improving manufacturing processes
