ABSTRACT
A common characteristic of all engineering works is that they should be undertaken in minimum time using limited resources such as people, materials, and money. Engineers have also to be creative and responsive in facing the challenge of sustainability. To move toward a more sustainable practice of engineering, the design process must be modified to enable engineers to tackle sustainability issues in a structured manner. Sustainable engineering design requires a system approach whereby sustainability is systematically integrated in the design rather than considered as an “add-on.” The large number of criteria that need to be considered when integrating sustainability issues with conventional technical issues can be problematic. The sustainable process design case study illustrates how sustainability considerations could be integrated into process design from project initiation through preliminary to detailed design. The product sustainability assessment was a comprehensive evaluation process with the consideration of the energy, environmental, resource, technical and socio-economic indicators.
