This book provides engineers with the necessary information to design sustainable processes, products and value chains. It describes the current consensus on sustainable development for four context levels: Planet, Society, Business, and Engineers. It also presents all required design steps: from problem definition, via synthesis of potential solutions, analysis of solutions, improvements to the final solution evaluation. For each design step, methods and guidelines are provided in relation to the goal of obtaining a sustainable solution; a solution that meets both the needs of people and all specific context constraints with regard to the planet and prosperity.
