Challenges for Design Engineers in Sustainable Engineering

Very few industrial processes only produce the target product, but other materials not desired by the manufacturer are also obtained. These unwanted products constitute the residues of the processes and their discharge contributes to the overall environmental impact. The concept of preventing pollution is gaining increased importance, and certain industries that are particularly similar in nature, could benefit from PPP (Pollution Prevention Program) cross-fertilization. Implementing PPP sets important targets and benefits. A number of codes of good practice lead to PPP, both from a management and technical viewpoints. The fast development of technology and pollution standards implies important challenges for environmental engineers, environmental research and development. Although there is no general route to success, there are however a number of pollution prevention and waste reduction schemes that apply. These alternatives and procedures are illustrated in the paper. It is clear that environment-caring companies will be more readily accepted by their human environment. It is also evident that the engineer of the 21st century faces new and complex environmental challenges. Research remains the backbone of successful development.
