More and more technical universities now advocate integrating sustainability in higher education and including it as a strategic goal for improving education's quality and relevance to society. This study examines 30 fourth-year chemical engineering students, graduates of a university course designed to combine their terminological domain with sustainability-oriented goals, focusing on topics like corporate sustainability, developing environmental policy, introduction to ISO 14001--Environmental Management Systems (EMS), and environmental legislation. The study explores their perception of industrial-environmental issues and asks--How did the study unit influence the students' ability to use their preexisting scientific knowledge, while relating to industrial-environmental issues? Our findings indicate that engineering students can develop industrial-environmental awareness, and make use of interdisciplinary knowledge beyond that strictly related to the realm of engineering. Regarding the research's particular aim--i.e. determining the study unit's influence on students' ability to relate industrial-environmental issues to their own field of engineering--the findings indeed show a change in the students' conceptions of environmental elements related to industry. The course graduates became more attentive to the environmental aspects associated with building and opening a factory, and the concepts they raised in connection with the topic gained in variety.
